There are two global -pools in the Staking module: the bonded pool and unbonding pool. Bonded Atoms -are part of the global bonded pool. If a candidate or delegator wants to unbond -its Atoms, those Atoms are moved to the the unbonding pool for the duration of -the unbonding period. In the Staking module, a pool is a logical concept, i.e., -there is no pool data structure that would be responsible for managing pool -resources. Instead, it is managed in a distributed way. More precisely, at the -global level, for each pool, we track only the total amount of bonded or unbonded -Atoms and the current amount of issued shares. A share is a unit of Atom distribution -and the value of the share (share-to-atom exchange rate) changes during -system execution. The share-to-atom exchange rate can be computed as: +collection of Atoms contributed by different Atom holders. There are three +pools in the Staking module: the bonded, unbonding, and unbonded pool. Bonded +Atoms are part of the global bonded pool. If a validator or delegator wants to +unbond its Shares, these Shares are moved to the the unbonding pool for the +duration of the unbonding period. From here normally Atoms will be moved +directly into the delegators wallet, however under the situation thatn an +entire validator gets unbonded, the Atoms of the delegations will remain with +the validator and moved to the unbonded pool.

A Tx is a Msg wrapped with authentication and fee data. + +### Messages + +Users can create messages containing arbitrary information by +implementing the `Msg` interface: + +```go +type Msg interface { + + // Return the message type. + // Must be alphanumeric or empty. + Type() string + + // Get the canonical byte representation of the Msg. + GetSignBytes() []byte + + // ValidateBasic does a simple validation check that + // doesn't require access to any other information. + ValidateBasic() error + + // Signers returns the addrs of signers that must sign. + // CONTRACT: All signatures must be present to be valid. + // CONTRACT: Returns addrs in some deterministic order. + GetSigners() []Address +} + +``` + +Messages must specify their type via the `Type()` method. The type should +correspond to the messages handler, so there can be many messages with the same +type. + +Messages must also specify how they are to be authenticated. The `GetSigners()` +method return a list of addresses that must sign the message, while the +`GetSignBytes()` method returns the bytes that must be signed for a signature +to be valid. + +Addresses in the SDK are arbitrary byte arrays that are hex-encoded when +displayed as a string or rendered in JSON. + +Messages can specify basic self-consistency checks using the `ValidateBasic()` +method to enforce that message contents are well formed before any actual logic +begins. + +For instance, the `Basecoin` message types are defined in `x/bank/tx.go`: + +```go +type MsgSend struct { + Inputs []Input `json:"inputs"` + Outputs []Output `json:"outputs"` +} + +type MsgIssue struct { + Banker sdk.Address `json:"banker"` + Outputs []Output `json:"outputs"` +} +``` + +Each specifies the addresses that must sign the message: + +```go +func (msg MsgSend) GetSigners() []sdk.Address { + addrs := make([]sdk.Address, len(msg.Inputs)) + for i, in := range msg.Inputs { + addrs[i] = in.Address + } + return addrs +} + +func (msg MsgIssue) GetSigners() []sdk.Address { + return []sdk.Address{msg.Banker} +} +``` + +### Transactions + +A transaction is a message with additional information for authentication: + +```go +type Tx interface { + + GetMsg() Msg + + // Signatures returns the signature of signers who signed the Msg. + // CONTRACT: Length returned is same as length of + // pubkeys returned from MsgKeySigners, and the order + // matches. + // CONTRACT: If the signature is missing (ie the Msg is + // invalid), then the corresponding signature is + // .Empty(). + GetSignatures() []StdSignature +} +``` + +The `tx.GetSignatures()` method returns a list of signatures, which must match +the list of addresses returned by `tx.Msg.GetSigners()`. The signatures come in +a standard form: + +```go +type StdSignature struct { + crypto.PubKey // optional + crypto.Signature + Sequence int64 +} +``` + +It contains the signature itself, as well as the corresponding account's +sequence number. The sequence number is expected to increment every time a +message is signed by a given account. This prevents "replay attacks", where +the same message could be executed over and over again. + +The `StdSignature` can also optionally include the public key for verifying the +signature. An application can store the public key for each address it knows +about, making it optional to include the public key in the transaction. In the +case of Basecoin, the public key only needs to be included in the first +transaction send by a given account - after that, the public key is forever +stored by the application and can be left out of transactions. + +The address responsible for paying the transactions fee is the first address +returned by msg.GetSigners(). The convenience function `FeePayer(tx Tx)` is provided +to return this. + +The standard way to create a transaction from a message is to use the `StdTx`: + +```go +type StdTx struct { + Msg + Signatures []StdSignature +} +``` + +### Encoding and Decoding Transactions + +Messages and transactions are designed to be generic enough for developers to +specify their own encoding schemes. This enables the SDK to be used as the +framwork for constructing already specified cryptocurrency state machines, for +instance Ethereum. + +When initializing an application, a developer must specify a `TxDecoder` +function which determines how an arbitrary byte array should be unmarshalled +into a `Tx`: + +```go +type TxDecoder func(txBytes []byte) (Tx, error) +``` + +In `Basecoin`, we use the Tendermint wire format and the `go-amino` library for +encoding and decoding all message types. The `go-amino` library has the nice +property that it can unmarshal into interface types, but it requires the +relevant types to be registered ahead of type. Registration happens on a +`Codec` object, so as not to taint the global name space. + +For instance, in `Basecoin`, we wish to register the `MsgSend` and `MsgIssue` +types: + +```go +cdc.RegisterInterface((*sdk.Msg)(nil), nil) +cdc.RegisterConcrete(bank.MsgSend{}, "cosmos-sdk/MsgSend", nil) +cdc.RegisterConcrete(bank.MsgIssue{}, "cosmos-sdk/MsgIssue", nil) +``` + +Note how each concrete type is given a name - these name determine the type's +unique "prefix bytes" during encoding. A registered type will always use the +same prefix-bytes, regardless of what interface it is satisfying. For more +details, see the [go-amino documentation](https://github.com/tendermint/go-amino/blob/develop). + + +## Storage + +### MultiStore + +MultiStore is like a root filesystem of an operating system, except +all the entries are fully Merkleized. You mount onto a MultiStore +any number of Stores. Currently only KVStores are supported, but in +the future we may support more kinds of stores, such as a HeapStore +or a NDStore for multidimensional storage. + +The MultiStore as well as all mounted stores provide caching (aka +cache-wrapping) for intermediate state (aka software transactional +memory) during the execution of transactions. In the case of the +KVStore, this also works for iterators. For example, after running +the app's AnteHandler, the MultiStore is cache-wrapped (and each +store is also cache-wrapped) so that should processing of the +transaction fail, at least the transaction fees are paid and +sequence incremented. + +The MultiStore as well as all stores support (or will support) +historical state pruning and snapshotting and various kinds of +queries with proofs. + +### KVStore + +Here we'll focus on the IAVLStore, which is a kind of KVStore. + +IAVLStore is a fast balanced dynamic Merkle store that also supports +iteration, and of course cache-wrapping, state pruning, and various +queries with proofs, such as proofs of existence, absence, range, +and so on. + +Here's how you mount them to a MultiStore. + +```go +mainDB, catDB := dbm.NewMemDB(), dbm.NewMemDB() +fooKey := sdk.NewKVStoreKey("foo") +barKey := sdk.NewKVStoreKey("bar") +catKey := sdk.NewKVStoreKey("cat") +ms := NewCommitMultiStore(mainDB) +ms.MountStoreWithDB(fooKey, sdk.StoreTypeIAVL, nil) +ms.MountStoreWithDB(barKey, sdk.StoreTypeIAVL, nil) +ms.MountStoreWithDB(catKey, sdk.StoreTypeIAVL, catDB) +``` + +In the example above, all IAVL nodes (inner and leaf) will be stored +in mainDB with the prefix of "s/k:foo/" and "s/k:bar/" respectively, +thus sharing the mainDB. All IAVL nodes (inner and leaf) for the +cat KVStore are stored separately in catDB with the prefix of +"s/\_/". The "s/k:KEY/" and "s/\_/" prefixes are there to +disambiguate store items from other items of non-storage concern. + + +## Context + +The SDK uses a `Context` to propogate common information across functions. The +`Context` is modeled after the Golang `context.Context` object, which has +become ubiquitous in networking middleware and routing applications as a means +to easily propogate request context through handler functions. + +The main information stored in the `Context` includes the application +MultiStore (see below), the last block header, and the transaction bytes. +Effectively, the context contains all data that may be necessary for processing +a transaction. + +Many methods on SDK objects receive a context as the first argument. + +## Handler + +Transaction processing in the SDK is defined through `Handler` functions: + +```go +type Handler func(ctx Context, tx Tx) Result +``` + +A handler takes a context and a transaction and returns a result. All +information necessary for processing a transaction should be available in the +context. + +While the context holds the entire application state (all referenced from the +root MultiStore), a particular handler only needs a particular kind of access +to a particular store (or two or more). Access to stores is managed using +capabilities keys and mappers. When a handler is initialized, it is passed a +key or mapper that gives it access to the relevant stores. + +```go +// File: cosmos-sdk/examples/basecoin/app/init_stores.go +app.BaseApp.MountStore(app.capKeyMainStore, sdk.StoreTypeIAVL) +app.accountMapper = auth.NewAccountMapper( + app.capKeyMainStore, // target store + &types.AppAccount{}, // prototype +) + +// File: cosmos-sdk/examples/basecoin/app/init_handlers.go +app.router.AddRoute("bank", bank.NewHandler(app.accountMapper)) + +// File: cosmos-sdk/x/bank/handler.go +// NOTE: Technically, NewHandler only needs a CoinMapper +func NewHandler(am sdk.AccountMapper) sdk.Handler { + return func(ctx sdk.Context, msg sdk.Msg) sdk.Result { + cm := CoinMapper{am} + ... + } +} +``` + +## AnteHandler + +### Handling Fee payment +### Handling Authentication + +## Accounts and x/auth + +### sdk.Account +### auth.BaseAccount +### auth.AccountMapper + +## Wire codec + +### Why another codec? +### vs encoding/json +### vs protobuf + +## KVStore example + +## Basecoin example + +The quintessential SDK application is Basecoin - a simple +multi-asset cryptocurrency. Basecoin consists of a set of +accounts stored in a Merkle tree, where each account may have +many coins. There are two message types: MsgSend and MsgIssue. +MsgSend allows coins to be sent around, while MsgIssue allows a +set of predefined users to issue new coins. + +## Conclusion diff --git a/docs/index.rst b/docs/index.rst new file mode 100644 index 000000000000..66e3f7cb8c1a --- /dev/null +++ b/docs/index.rst @@ -0,0 +1,59 @@ +..

This is a Merkle proof that the result of the query is actually +contained in the state. And the state's Merkle root is contained in a +recent block header. Behind the scenes, ``countercli`` will not only +verify that this state matches the header, but also that the header is +properly signed by the known validator set. It will even update the +validator set as needed, so long as there have not been major changes +and it is secure to do so. So, if you wonder why the query may take a +second... there is a lot of work going on in the background to make sure +even a lying full node can't trick your client. + +Accounts and Transactions +------------------------- + +For a better understanding of how to further use the tools, it helps to +understand the underlying data structures. + +Accounts +~~~~~~~~ + +The Basecoin state consists entirely of a set of accounts. Each account +contains a public key, a balance in many different coin denominations, +and a strictly increasing sequence number for replay protection. This +type of account was directly inspired by accounts in Ethereum, and is +unlike Bitcoin's use of Unspent Transaction Outputs (UTXOs). Note +Basecoin is a multi-asset cryptocurrency, so each account can have many +different kinds of tokens. + +:: + + type Account struct { + PubKey crypto.PubKey `json:"pub_key"` // May be nil, if not known. + Sequence int `json:"sequence"` + Balance Coins `json:"coins"` + } + + type Coins []Coin + + type Coin struct { + Denom string `json:"denom"` + Amount int64 `json:"amount"` + } + +If you want to add more coins to a blockchain, you can do so manually in +the ``~/.basecoin/genesis.json`` before you start the blockchain for the +first time. + +Accounts are serialized and stored in a Merkle tree under the key +``base/a/
``, where ``
`` is the address of the account. +Typically, the address of the account is the 20-byte ``RIPEMD160`` hash +of the public key, but other formats are acceptable as well, as defined +in the `Tendermint crypto +library `__. The Merkle tree +used in Basecoin is a balanced, binary search tree, which we call an +`IAVL tree `__. + +Transactions +~~~~~~~~~~~~ + +Basecoin defines a transaction type, the ``SendTx``, which allows tokens +to be sent to other accounts. The ``SendTx`` takes a list of inputs and +a list of outputs, and transfers all the tokens listed in the inputs +from their corresponding accounts to the accounts listed in the output. +The ``SendTx`` is structured as follows: + +:: + + type SendTx struct { + Gas int64 `json:"gas"` + Fee Coin `json:"fee"` + Inputs []TxInput `json:"inputs"` + Outputs []TxOutput `json:"outputs"` + } + + type TxInput struct { + Address []byte `json:"address"` // Hash of the PubKey + Coins Coins `json:"coins"` // + Sequence int `json:"sequence"` // Must be 1 greater than the last committed TxInput + Signature crypto.Signature `json:"signature"` // Depends on the PubKey type and the whole Tx + PubKey crypto.PubKey `json:"pub_key"` // Is present iff Sequence == 0 + } + + type TxOutput struct { + Address []byte `json:"address"` // Hash of the PubKey + Coins Coins `json:"coins"` // + } + +Note the ``SendTx`` includes a field for ``Gas`` and ``Fee``. The +``Gas`` limits the total amount of computation that can be done by the +transaction, while the ``Fee`` refers to the total amount paid in fees. +This is slightly different from Ethereum's concept of ``Gas`` and +``GasPrice``, where ``Fee = Gas x GasPrice``. In Basecoin, the ``Gas`` +and ``Fee`` are independent, and the ``GasPrice`` is implicit. + +In Basecoin, the ``Fee`` is meant to be used by the validators to inform +the ordering of transactions, like in Bitcoin. And the ``Gas`` is meant +to be used by the application plugin to control its execution. There is +currently no means to pass ``Fee`` information to the Tendermint +validators, but it will come soon... + +Note also that the ``PubKey`` only needs to be sent for +``Sequence == 0``. After that, it is stored under the account in the +Merkle tree and subsequent transactions can exclude it, using only the +``Address`` to refer to the sender. Ethereum does not require public +keys to be sent in transactions as it uses a different elliptic curve +scheme which enables the public key to be derived from the signature +itself. + +Finally, note that the use of multiple inputs and multiple outputs +allows us to send many different types of tokens between many different +accounts at once in an atomic transaction. Thus, the ``SendTx`` can +serve as a basic unit of decentralized exchange. When using multiple +inputs and outputs, you must make sure that the sum of coins of the +inputs equals the sum of coins of the outputs (no creating money), and +that all accounts that provide inputs have signed the transaction. + +Clean Up +-------- + +**WARNING:** Running these commands will wipe out any existing +information in both the ``~/.basecli`` and ``~/.basecoin`` directories, +including private keys. + +To remove all the files created and refresh your environment (e.g., if +starting this tutorial again or trying something new), the following +commands are run: + +:: + + basecli reset_all + rm -rf ~/.basecoin + +In this guide, we introduced the ``basecoin`` and ``basecli`` tools, +demonstrated how to start a new basecoin blockchain and how to send +tokens between accounts, and discussed the underlying data types for +accounts and transactions, specifically the ``Account`` and the +``SendTx``. diff --git a/docs/old/basecoin/extensions.rst b/docs/old/basecoin/extensions.rst new file mode 100644 index 000000000000..6f31222deffa --- /dev/null +++ b/docs/old/basecoin/extensions.rst @@ -0,0 +1,215 @@ +Basecoin Extensions +=================== + +TODO: re-write for extensions + +In the `previous guide `__, we saw how to use the +``basecoin`` tool to start a blockchain and the ``basecli`` tools to +send transactions.

We can build +plugins that take many arguments of different types, and easily extend +the tool to accomodate them. Of course, we can also expose queries on +our plugin: + +:: + + countercli query counter + +Tada! We can now see that our custom counter plugin transactions went +through. You should see a Counter value of 1 representing the number of +valid transactions. If we send another transaction, and then query +again, we will see the value increment.

The ``Name`` field in the +``AppTx`` refers to the particular plugin which should process the +transaction, and the ``Data`` field of the ``AppTx`` is the data to be +forwarded to the plugin for processing. + +Note the ``AppTx`` also has a ``Gas`` and ``Fee``, with the same meaning +as for the ``SendTx``. It also includes a single ``TxInput``, which +specifies the sender of the transaction, and some coins that can be +forwarded to the plugin as well. + +Plugins +------- + +A plugin is simply a Go package that implements the ``Plugin`` +interface: + +:: + + type Plugin interface { + + // Name of this plugin, should be short. + Name() string + + // Run a transaction from ABCI DeliverTx + RunTx(store KVStore, ctx CallContext, txBytes []byte) (res abci.Result) + + // Other ABCI message handlers + SetOption(store KVStore, key string, value string) (log string) + InitChain(store KVStore, vals []*abci.Validator) + BeginBlock(store KVStore, hash []byte, header *abci.Header) + EndBlock(store KVStore, height uint64) (res abci.ResponseEndBlock) + } + + type CallContext struct { + CallerAddress []byte // Caller's Address (hash of PubKey) + CallerAccount *Account // Caller's Account, w/ fee & TxInputs deducted + Coins Coins // The coins that the caller wishes to spend, excluding fees + } + +The workhorse of the plugin is ``RunTx``, which is called when an +``AppTx`` is processed. The ``Data`` from the ``AppTx`` is passed in as +the ``txBytes``, while the ``Input`` from the ``AppTx`` is used to +populate the ``CallContext``. + +Note that ``RunTx`` also takes a ``KVStore`` - this is an abstraction +for the underlying Merkle tree which stores the account data. By passing +this to the plugin, we enable plugins to update accounts in the Basecoin +state directly, and also to store arbitrary other information in the +state. In this way, the functionality and state of a Basecoin-derived +cryptocurrency can be greatly extended. One could imagine going so far +as to implement the Ethereum Virtual Machine as a plugin! + +For details on how to initialize the state using ``SetOption``, see the +`guide to using the basecoin tool `__. + +Implement your own +------------------ + +To implement your own plugin and tooling, make a copy of +``docs/guide/counter``, and modify the code accordingly. Here, we will +briefly describe the design and the changes to be made, but see the code +for more details. + +First is the ``cmd/counter/main.go``, which drives the program. It can +be left alone, but you should change any occurrences of ``counter`` to +whatever your plugin tool is going to be called. You must also register +your plugin(s) with the basecoin app with ``RegisterStartPlugin``. + +The light-client is located in ``cmd/countercli/main.go`` and allows for +transaction and query commands.

The most important part of +the implementation is the ``RunTx`` method, which determines the meaning +of the data sent along in the ``AppTx``. In our example, we define a new +transaction type, the ``CounterTx``, which we expect to be encoded in +the ``AppTx.Data``, and thus to be decoded in the ``RunTx`` method, and +used to update the plugin state. + +For more examples and inspiration, see our `repository of example +plugins `__. + +Conclusion +---------- + +In this guide, we demonstrated how to create a new plugin and how to +extend the ``basecoin`` tool to start a blockchain with the plugin +enabled and send transactions to it.

This is +mainly to provide a background and general understanding of the +different words and concepts that are used. Other documents will explain +in more detail how to combine these concepts to build a particular +application. + +Transaction +----------- + +A transaction is a packet of binary data that contains all information +to validate and perform an action on the blockchain. The only other data +that it interacts with is the current state of the chain (key-value +store), and it must have a deterministic action. The transaction is the +main piece of one request. + +We currently make heavy use of +`go-amino `__ to +provide binary and json encodings and decodings for ``struct`` or +interface\ ``objects. Here, encoding and decoding operations are designed to operate with interfaces nested any amount times (like an onion!). There is one public``\ TxMapper\` +in the basecoin root package, and all modules can register their own +transaction types there. This allows us to deserialize the entire +transaction in one location (even with types defined in other repos), to +easily embed an arbitrary transaction inside another without specifying +the type, and provide an automatic json representation allowing for +users (or apps) to inspect the chain. + +Note how we can wrap any other transaction, add a fee level, and not +worry about the encoding in our module any more? + +:: + + type Fee struct { + Fee coin.Coin `json:"fee"` + Payer basecoin.Actor `json:"payer"` // the address who pays the fee + Tx basecoin.Tx `json:"tx"` + } + +Context (ctx) +------------- + +As a request passes through the system, it may pick up information such +as the block height the request runs at. In order to carry this information +between modules it is saved to the context. Further, all information +must be deterministic from the context in which the request runs (based +on the transaction and the block it was included in) and can be used to +validate the transaction. + +Data Store +---------- + +In order to provide proofs to Tendermint, we keep all data in one +key-value (kv) store which is indexed with a merkle tree. This allows +for the easy generation of a root hash and proofs for queries without +requiring complex logic inside each module. Standardization of this +process also allows powerful light-client tooling as any store data may +be verified on the fly. + +The largest limitation of the current implemenation of the kv-store is +that interface that the application must use can only ``Get`` and +``Set`` single data points. That said, there are some data structures +like queues and range queries that are available in ``state`` package. +These provide higher-level functionality in a standard format, but have +not yet been integrated into the kv-store interface. + +Isolation +--------- + +One of the main arguments for blockchain is security. So while we +encourage the use of third-party modules, all developers must be +vigilant against security holes. If you use the +`stack `__ +package, it will provide two different types of compartmentalization +security. + +The first is to limit the working kv-store space of each module. When +``DeliverTx`` is called for a module, it is never given the entire data +store, but rather only its own prefixed subset of the store. This is +achieved by prefixing all keys transparently with +`` + 0x0``, using the null byte as a separator. Since the +module name must be a string, no malicious naming scheme can ever lead +to a collision. Inside a module, we can write using any key value we +desire without the possibility that we have modified data belonging to +separate module. + +The second is to add permissions to the transaction context. The +transaction context can specify that the tx has been signed by one or +multiple specific actors. + +A transactions will only be executed if the permission requirements have +been fulfilled. For example the sender of funds must have signed, or 2 +out of 3 multi-signature actors must have signed a joint account. To +prevent the forgery of account signatures from unintended modules each +permission is associated with the module that granted it (in this case +`auth `__), +and if a module tries to add a permission for another module, it will +panic. There is also protection if a module creates a brand new fake +context to trick the downstream modules. Each context enforces the rules +on how to make child contexts, and the stack builder enforces +that the context passed from one level to the next is a valid child of +the original one. + +These security measures ensure that modules can confidently write to +their local section of the database and trust the permissions associated +with the context, without concern of interference from other modules. +(Okay, if you see a bunch of C-code in the module traversing through all +the memory space of the application, then get worried....) + +Handler +------- + +The ABCI interface is handled by ``app``, which translates these data +structures into an internal format that is more convenient, but unable +to travel over the wire. The basic interface for any code that modifies +state is the ``Handler`` interface, which provides four methods: + +:: + + Name() string + CheckTx(ctx Context, store state.KVStore, tx Tx) (Result, error) + DeliverTx(ctx Context, store state.KVStore, tx Tx) (Result, error) + SetOption(l log.Logger, store state.KVStore, module, key, value string) (string, error) + +Note the ``Context``, ``KVStore``, and ``Tx`` as principal carriers of +information. And that Result is always success, and we have a second +error return for errors (which is much more standard golang that +``res.IsErr()``) + +The ``Handler`` interface is designed to be the basis for all modules +that execute transactions, and this can provide a large degree of code +interoperability, much like ``http.Handler`` does in golang web +development. + +Modules +------- + +TODO: update (s/Modules/handlers+mappers+stores/g) & add Msg + Tx (a signed message) + +A module is a set of functionality which should be typically designed as +self-sufficient. Common elements of a module are: + +- transaction types (either end transactions, or transaction wrappers) +- custom error codes +- data models (to persist in the kv-store) +- handler (to handle any end transactions) + +Dispatcher +---------- + +We usually will want to have multiple modules working together, and need +to make sure the correct transactions get to the correct module. So we +have ``coin`` sending money, ``roles`` to create multi-sig accounts, and +``ibc`` for following other chains all working together without +interference. + +We can then register a ``Dispatcher``, which +also implements the ``Handler`` interface. We then register a list of +modules with the dispatcher. Every module has a unique ``Name()``, which +is used for isolating its state space. We use this same name for routing +transactions. Each transaction implementation must be registed with +go-amino via ``TxMapper``, so we just look at the registered name of this +transaction, which should be of the form ``/xxx``. The +dispatcher grabs the appropriate module name from the tx name and routes +it if the module is present. + +This all seems like a bit of magic, but really we're just making use of +go-amino magic that we are already using, rather than add another layer. +For all the transactions to be properly routed, the only thing you need +to remember is to use the following pattern: + +:: + + const ( + NameCoin = "coin" + TypeSend = NameCoin + "/send" + ) + +Permissions +----------- + +TODO: replaces perms with object capabilities/object capability keys +- get rid of IPC + +IPC requires a more complex permissioning system to allow the modules to +have limited access to each other and also to allow more types of +permissions than simple public key signatures. Rather than just use an +address to identify who is performing an action, we can use a more +complex structure: + +:: + + type Actor struct { + ChainID string `json:"chain"` // this is empty unless it comes from a different chain + App string `json:"app"` // the app that the actor belongs to + Address data.Bytes `json:"addr"` // arbitrary app-specific unique id + } + +Here, the ``Actor`` abstracts any address that can authorize actions, +hold funds, or initiate any sort of transaction. It doesn't just have to +be a pubkey on this chain, it could stem from another app (such as +multi-sig account), or even another chain (via IBC) + +``ChainID`` is for IBC, discussed below. Let's focus on ``App`` and +``Address``. For a signature, the App is ``auth``, and any modules can +check to see if a specific public key address signed like this +``ctx.HasPermission(auth.SigPerm(addr))``. However, we can also +authorize a tx with ``roles``, which handles multi-sig accounts, it +checks if there were enough signatures by checking as above, then it can +add the role permission like +``ctx= ctx.WithPermissions(NewPerm(assume.Role))`` + +In addition to the permissions schema, the Actors are addresses just +like public key addresses. So one can create a mulit-sig role, then send +coin there, which can only be moved upon meeting the authorization +requirements from that module. ``coin`` doesn't even know the existence +of ``roles`` and one could build any other sort of module to provide +permissions (like bind the outcome of an election to move coins or to +modify the accounts on a role). + +One idea - not yet implemented - is to provide scopes on the +permissions. Currently, if I sign a transaction to one module, it can +pass it on to any other module over IPC with the same permissions. It +could move coins, vote in an election, or anything else. Ideally, when +signing, one could also specify the scope(s) that this signature +authorizes. The `oauth +protocol `__ also has to deal +with a similar problem, and maybe could provide some inspiration. diff --git a/docs/old/ibc.rst b/docs/old/ibc.rst new file mode 100644 index 000000000000..30b9a16faf91 --- /dev/null +++ b/docs/old/ibc.rst @@ -0,0 +1,424 @@ +IBC +=== + +TODO: update in light of latest SDK (this document is currently out of date) + +One of the most exciting elements of the Cosmos Network is the +InterBlockchain Communication (IBC) protocol, which enables +interoperability across different blockchains. We implemented IBC as a +basecoin plugin, and we'll show you how to use it to send tokens across +blockchains! + +Please note: this tutorial assumes familiarity with the Cosmos SDK. + +The IBC plugin defines a new set of transactions as subtypes of the +``AppTx``. The plugin's functionality is accessed by setting the +``AppTx.Name`` field to ``"IBC"``, and setting the ``Data`` field to the +serialized IBC transaction type. + +We'll demonstrate exactly how this works below. + +Inter BlockChain Communication +------------------------------ + +Let's review the IBC protocol. The purpose of IBC is to enable one +blockchain to function as a light-client of another. Since we are using +a classical Byzantine Fault Tolerant consensus algorithm, light-client +verification is cheap and easy: all we have to do is check validator +signatures on the latest block, and verify a Merkle proof of the state. + +In Tendermint, validators agree on a block before processing it. This +means that the signatures and state root for that block aren't included +until the next block. Thus, each block contains a field called +``LastCommit``, which contains the votes responsible for committing the +previous block, and a field in the block header called ``AppHash``, +which refers to the Merkle root hash of the application after processing +the transactions from the previous block. So, if we want to verify the +``AppHash`` from height H, we need the signatures from ``LastCommit`` at +height H+1. (And remember that this ``AppHash`` only contains the +results from all transactions up to and including block H-1) + +Unlike Proof-of-Work, the light-client protocol does not need to +download and check all the headers in the blockchain - the client can +always jump straight to the latest header available, so long as the +validator set has not changed much. If the validator set is changing, +the client needs to track these changes, which requires downloading +headers for each block in which there is a significant change. Here, we +will assume the validator set is constant, and postpone handling +validator set changes for another time. + +Now we can describe exactly how IBC works. Suppose we have two +blockchains, ``chain1`` and ``chain2``, and we want to send some data +from ``chain1`` to ``chain2``. We need to do the following: 1. Register +the details (ie. chain ID and genesis configuration) of ``chain1`` on +``chain2`` 2. Within ``chain1``, broadcast a transaction that creates an +outgoing IBC packet destined for ``chain2`` 3. Broadcast a transaction +to ``chain2`` informing it of the latest state (ie. header and commit +signatures) of ``chain1`` 4. Post the outgoing packet from ``chain1`` to +``chain2``, including the proof that it was indeed committed on +``chain1``. Note ``chain2`` can only verify this proof because it has a +recent header and commit. + +Each of these steps involves a separate IBC transaction type. Let's take +them up in turn. + +IBCRegisterChainTx +~~~~~~~~~~~~~~~~~~ + +The ``IBCRegisterChainTx`` is used to register one chain on another. It +contains the chain ID and genesis configuration of the chain to +register: + +:: + + type IBCRegisterChainTx struct { BlockchainGenesis } + + type BlockchainGenesis struct { ChainID string Genesis string } + +This transaction should only be sent once for a given chain ID, and +successive sends will return an error. + +IBCUpdateChainTx +~~~~~~~~~~~~~~~~ + +The ``IBCUpdateChainTx`` is used to update the state of one chain on +another. It contains the header and commit signatures for some block in +the chain: + +:: + + type IBCUpdateChainTx struct { + Header tm.Header + Commit tm.Commit + } + +In the future, it needs to be updated to include changes to the +validator set as well. Anyone can relay an ``IBCUpdateChainTx``, and +they only need to do so as frequently as packets are being sent or the +validator set is changing. + +IBCPacketCreateTx +~~~~~~~~~~~~~~~~~ + +The ``IBCPacketCreateTx`` is used to create an outgoing packet on one +chain. The packet itself contains the source and destination chain IDs, +a sequence number (i.e. an integer that increments with every message +sent between this pair of chains), a packet type (e.g. coin, data, +etc.), and a payload. + +:: + + type IBCPacketCreateTx struct { + Packet + } + + type Packet struct { + SrcChainID string + DstChainID string + Sequence uint64 + Type string + Payload []byte + } + +We have yet to define the format for the payload, so, for now, it's just +arbitrary bytes. + +One way to think about this is that ``chain2`` has an account on +``chain1``. With a ``IBCPacketCreateTx`` on ``chain1``, we send funds to +that account. Then we can prove to ``chain2`` that there are funds +locked up for it in it's account on ``chain1``. Those funds can only be +unlocked with corresponding IBC messages back from ``chain2`` to +``chain1`` sending the locked funds to another account on ``chain1``. + +IBCPacketPostTx +~~~~~~~~~~~~~~~ + +The ``IBCPacketPostTx`` is used to post an outgoing packet from one +chain to another. It contains the packet and a proof that the packet was +committed into the state of the sending chain: + +:: + + type IBCPacketPostTx struct { + FromChainID string // The immediate source of the packet, not always Packet.SrcChainID + FromChainHeight uint64 // The block height in which Packet was committed, to check Proof Packet + Proof *merkle.IAVLProof + } + +The proof is a Merkle proof in an IAVL tree, our implementation of a +balanced, Merklized binary search tree. It contains a list of nodes in +the tree, which can be hashed together to get the Merkle root hash. This +hash must match the ``AppHash`` contained in the header at +``FromChainHeight + 1`` + +- note the ``+ 1`` is necessary since ``FromChainHeight`` is the height + in which the packet was committed, and the resulting state root is + not included until the next block. + +IBC State +~~~~~~~~~ + +Now that we've seen all the transaction types, let's talk about the +state. Each chain stores some IBC state in its Merkle tree. For each +chain being tracked by our chain, we store: + +- Genesis configuration +- Latest state +- Headers for recent heights + +We also store all incoming (ingress) and outgoing (egress) packets. + +The state of a chain is updated every time an ``IBCUpdateChainTx`` is +committed. New packets are added to the egress state upon +``IBCPacketCreateTx``. New packets are added to the ingress state upon +``IBCPacketPostTx``, assuming the proof checks out. + +Merkle Queries +-------------- + +The Basecoin application uses a single Merkle tree that is shared across +all its state, including the built-in accounts state and all plugin +state. For this reason, it's important to use explicit key names and/or +hashes to ensure there are no collisions. + +We can query the Merkle tree using the ABCI Query method. If we pass in +the correct key, it will return the corresponding value, as well as a +proof that the key and value are contained in the Merkle tree. + +The results of a query can thus be used as proof in an +``IBCPacketPostTx``. + +Relay +----- + +While we need all these packet types internally to keep track of all the +proofs on both chains in a secure manner, for the normal work-flow, we +can run a relay node that handles the cross-chain interaction. + +In this case, there are only two steps. First ``basecoin relay init``, +which must be run once to register each chain with the other one, and +make sure they are ready to send and recieve. And then +``basecoin relay start``, which is a long-running process polling the +queue on each side, and relaying all new message to the other block. + +This requires that the relay has access to accounts with some funds on +both chains to pay for all the ibc packets it will be forwarding. + +Try it out +---------- + +Now that we have all the background knowledge, let's actually walk +through the tutorial. + +Make sure you have installed `basecoin and +basecli `__. + +Basecoin is a framework for creating new cryptocurrency applications. It +comes with an ``IBC`` plugin enabled by default. + +You will also want to install the +`jq `__ for handling JSON at the command +line. + +If you have any trouble with this, you can also look at the `test +scripts `__ or just run ``make test_cli`` in basecoin +repo. Otherwise, open up 5 (yes 5!) terminal tabs.... + +Preliminaries +~~~~~~~~~~~~~ + +:: + + # first, clean up any old garbage for a fresh slate... + rm -rf ~/.ibcdemo/ + +Let's start by setting up some environment variables and aliases: + +:: + + export BCHOME1_CLIENT=~/.ibcdemo/chain1/client + export BCHOME1_SERVER=~/.ibcdemo/chain1/server + export BCHOME2_CLIENT=~/.ibcdemo/chain2/client + export BCHOME2_SERVER=~/.ibcdemo/chain2/server + alias basecli1="basecli --home $BCHOME1_CLIENT" + alias basecli2="basecli --home $BCHOME2_CLIENT" + alias basecoin1="basecoin --home $BCHOME1_SERVER" + alias basecoin2="basecoin --home $BCHOME2_SERVER" + +This will give us some new commands to use instead of raw ``basecli`` +and ``basecoin`` to ensure we're using the right configuration for the +chain we want to talk to. + +We also want to set some chain IDs: + +:: + + export CHAINID1="test-chain-1" + export CHAINID2="test-chain-2" + +And since we will run two different chains on one machine, we need to +maintain different sets of ports: + +:: + + export PORT_PREFIX1=1234 + export PORT_PREFIX2=2345 + export RPC_PORT1=${PORT_PREFIX1}7 + export RPC_PORT2=${PORT_PREFIX2}7 + +Setup Chain 1 +~~~~~~~~~~~~~ + +Now, let's create some keys that we can use for accounts on +test-chain-1: + +:: + + basecli1 keys new money + basecli1 keys new gotnone + export MONEY=$(basecli1 keys get money | awk '{print $2}') + export GOTNONE=$(basecli1 keys get gotnone | awk '{print $2}') + +and create an initial configuration giving lots of coins to the $MONEY +key: + +:: + + basecoin1 init --chain-id $CHAINID1 $MONEY + +Now start basecoin: + +:: + + sed -ie "s/4665/$PORT_PREFIX1/" $BCHOME1_SERVER/config.toml + + basecoin1 start &> basecoin1.log & + +Note the ``sed`` command to replace the ports in the config file.

So we have two chains running on your local machine, with different +keys on each. Let's hook them up together by starting a relay process to +forward messages from one chain to the other. + +The relay account needs some money in it to pay for the ibc messages, so +for now, we have to transfer some cash from the rich accounts before we +start the actual relay. + +:: + + # note that this key.json file is a hardcoded demo for all chains, this will + # be updated in a future release + RELAY_KEY=$BCHOME1_SERVER/key.json + RELAY_ADDR=$(cat $RELAY_KEY | jq .address | tr -d \") + + basecli1 tx send --amount=100000mycoin --sequence=1 --to=$RELAY_ADDR--name=money + basecli1 query account $RELAY_ADDR + + basecli2 tx send --amount=100000mycoin --sequence=1 --to=$RELAY_ADDR --name=moremoney + basecli2 query account $RELAY_ADDR + +Now we can start the relay process. + +:: + + basecoin relay init --chain1-id=$CHAINID1 --chain2-id=$CHAINID2 \ + --chain1-addr=tcp://localhost:${RPC_PORT1} --chain2-addr=tcp://localhost:${RPC_PORT2} \ + --genesis1=${BCHOME1_SERVER}/genesis.json --genesis2=${BCHOME2_SERVER}/genesis.json \ + --from=$RELAY_KEY + + basecoin relay start --chain1-id=$CHAINID1 --chain2-id=$CHAINID2 \ + --chain1-addr=tcp://localhost:${RPC_PORT1} --chain2-addr=tcp://localhost:${RPC_PORT2} \ + --from=$RELAY_KEY &> relay.log & + +This should start up the relay, and assuming no error messages came out, +the two chains are now fully connected over IBC. Let's use this to send +our first tx accross the chains... + +Sending cross-chain payments +~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The hard part is over, we set up two blockchains, a few private keys, +and a secure relay between them. Now we can enjoy the fruits of our +labor... + +:: + + # Here's an empty account on test-chain-2 + basecli2 query account $BROKE + +:: + + # Let's send some funds from test-chain-1 + basecli1 tx send --amount=12345mycoin --sequence=2 --to=test-chain-2/$BROKE --name=money + +:: + + # give it time to arrive... + sleep 2 + # now you should see 12345 coins! + basecli2 query account $BROKE + +You're no longer broke! Cool, huh? Now have fun exploring and sending +coins across the chains. And making more accounts as you want to. + +Conclusion +---------- + +In this tutorial we explained how IBC works, and demonstrated how to use +it to communicate between two chains. We did the simplest communciation +possible: a one way transfer of data from chain1 to chain2. The most +important part was that we updated chain2 with the latest state (i.e. +header and commit) of chain1, and then were able to post a proof to +chain2 that a packet was committed to the outgoing state of chain1. + +In a future tutorial, we will demonstrate how to use IBC to actually +transfer tokens between two blockchains, but we'll do it with real +testnets deployed across multiple nodes on the network.

The +framework is designed around a modular execution stack which allows +applications to mix and match elements as desired. In addition, +all modules are sandboxed for greater application security. + +Framework Overview +------------------ + +Object-Capability Model +~~~~~~~~~~~~~~~~~~~~~~~ + +When thinking about security, it's good to start with a specific threat model. Our threat model is the following: + +:: + + We assume that a thriving ecosystem of Cosmos-SDK modules that are easy to compose into a blockchain application will contain faulty or malicious modules. + +The Cosmos-SDK is designed to address this threat by being the foundation of an object capability system. + +:: + + The structural properties of object capability systems favor + modularity in code design and ensure reliable encapsulation in + code implementation. + + These structural properties facilitate the analysis of some + security properties of an object-capability program or operating + system. Some of these — in particular, information flow properties + — can be analyzed at the level of object references and + connectivity, independent of any knowledge or analysis of the code + that determines the behavior of the objects. As a consequence, + these security properties can be established and maintained in the + presence of new objects that contain unknown and possibly + malicious code. + + These structural properties stem from the two rules governing + access to existing objects: + + 1) An object A can send a message to B only if object A holds a + reference to B. + + 2) An object A can obtain a reference to C only + if object A receives a message containing a reference to C. As a + consequence of these two rules, an object can obtain a reference + to another object only through a preexisting chain of references. + In short, "Only connectivity begets connectivity." + +See the `wikipedia article `__ for more information. + +Strictly speaking, Golang does not implement object capabilities completely, because of several issues: + +* pervasive ability to import primitive modules (e.g. "unsafe", "os") +* pervasive ability to override module vars https://github.com/golang/go/issues/23161 +* data-race vulnerability where 2+ goroutines can create illegal interface values + +The first is easy to catch by auditing imports and using a proper dependency version control system like Dep. The second and third are unfortunate but it can be audited with some cost. + +Perhaps `Go2 will implement the object capability model `__. + +What does it look like? +^^^^^^^^^^^^^^^^^^^^^^^ + +Only reveal what is necessary to get the work done. + +For example, the following code snippet violates the object capabilities principle: + +:: + + type AppAccount struct {...} + var account := &AppAccount{ + Address: pub.Address(), + Coins: sdk.Coins{{"ATM", 100}}, + } + var sumValue := externalModule.ComputeSumValue(account) + +The method "ComputeSumValue" implies a pure function, yet the implied capability of accepting a pointer value is the capability to modify that value. The preferred method signature should take a copy instead. + +:: + + var sumValue := externalModule.ComputeSumValue(*account) + +In the Cosmos SDK, you can see the application of this principle in the basecoin examples folder. + +:: + + // File: cosmos-sdk/examples/basecoin/app/init_handlers.go + package app + + import ( + "github.com/cosmos/cosmos-sdk/x/bank" + "github.com/cosmos/cosmos-sdk/x/sketchy" + ) + + func (app *BasecoinApp) initRouterHandlers() { + + // All handlers must be added here. + // The order matters. + app.router.AddRoute("bank", bank.NewHandler(app.accountMapper)) + app.router.AddRoute("sketchy", sketchy.NewHandler()) + } + +In the Basecoin example, the sketchy handler isn't provided an account mapper, which does provide the bank handler with the capability (in conjunction with the context of a transaction run). + +Security Overview +----------------- + +For examples, see the `examples `__ directory. + +Design Goals +~~~~~~~~~~~~ + +The design of the Cosmos SDK is based on the principles of "capabilities systems". + +Capabilities systems +~~~~~~~~~~~~~~~~~~~~ + +TODO: + +* Need for module isolation +* Capability is implied permission +* Link to thesis + +Tx & Msg +~~~~~~~~ + +The SDK distinguishes between transactions (Tx) and messages +(Msg). A Tx is a Msg wrapped with authentication and fee data. + +Messages +^^^^^^^^ + +Users can create messages containing arbitrary information by +implementing the ``Msg`` interface: + +:: + + type Msg interface { + + // Return the message type. + // Must be alphanumeric or empty. + Type() string + + // Get the canonical byte representation of the Msg. + GetSignBytes() []byte + + // ValidateBasic does a simple validation check that + // doesn't require access to any other information. + ValidateBasic() error + + // Signers returns the addrs of signers that must sign. + // CONTRACT: All signatures must be present to be valid. + // CONTRACT: Returns addrs in some deterministic order. + GetSigners() []Address + } + +Messages must specify their type via the ``Type()`` method. The type should +correspond to the messages handler, so there can be many messages with the same +type. + +Messages must also specify how they are to be authenticated. The ``GetSigners()`` +method return a list of addresses that must sign the message, while the +``GetSignBytes()`` method returns the bytes that must be signed for a signature +to be valid. + +Addresses in the SDK are arbitrary byte arrays that are hex-encoded when +displayed as a string or rendered in JSON. + +Messages can specify basic self-consistency checks using the ``ValidateBasic()`` +method to enforce that message contents are well formed before any actual logic +begins. + +For instance, the ``Basecoin`` message types are defined in ``x/bank/tx.go``: + +:: + + type SendMsg struct { + Inputs []Input `json:"inputs"` + Outputs []Output `json:"outputs"` + } + + type IssueMsg struct { + Banker sdk.Address `json:"banker"` + Outputs []Output `json:"outputs"` + } + +Each specifies the addresses that must sign the message: + +:: + + func (msg SendMsg) GetSigners() []sdk.Address { + addrs := make([]sdk.Address, len(msg.Inputs)) + for i, in := range msg.Inputs { + addrs[i] = in.Address + } + return addrs + } + + func (msg IssueMsg) GetSigners() []sdk.Address { + return []sdk.Address{msg.Banker} + } + +Transactions +^^^^^^^^^^^^ + +A transaction is a message with additional information for authentication: + +:: + + type Tx interface { + + GetMsg() Msg + + // Signatures returns the signature of signers who signed the Msg. + // CONTRACT: Length returned is same as length of + // pubkeys returned from MsgKeySigners, and the order + // matches. + // CONTRACT: If the signature is missing (ie the Msg is + // invalid), then the corresponding signature is + // .Empty(). + GetSignatures() []StdSignature + } + +The ``tx.GetSignatures()`` method returns a list of signatures, which must match +the list of addresses returned by ``tx.Msg.GetSigners()``. The signatures come in +a standard form: + +:: + + type StdSignature struct { + crypto.PubKey // optional + crypto.Signature + AccountNumber int64 + Sequence int64 + } + +It contains the signature itself, as well as the corresponding account's account and +sequence numbers. The sequence number is expected to increment every time a +message is signed by a given account. The account number stays the same and is assigned +when the account is first generated. These prevent "replay attacks", where +the same message could be executed over and over again. + +The ``StdSignature`` can also optionally include the public key for verifying the +signature. An application can store the public key for each address it knows +about, making it optional to include the public key in the transaction. In the +case of Basecoin, the public key only needs to be included in the first +transaction send by a given account - after that, the public key is forever +stored by the application and can be left out of transactions. + +The standard way to create a transaction from a message is to use the ``StdTx``: + +:: + + type StdTx struct { + Msg + Signatures []StdSignature + } + +Encoding and Decoding Transactions +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Messages and transactions are designed to be generic enough for developers to +specify their own encoding schemes. This enables the SDK to be used as the +framwork for constructing already specified cryptocurrency state machines, for +instance Ethereum. + +When initializing an application, a developer must specify a ``TxDecoder`` +function which determines how an arbitrary byte array should be unmarshalled +into a ``Tx``: + +:: + + type TxDecoder func(txBytes []byte) (Tx, error) + +In ``Basecoin``, we use the Tendermint wire format and the ``go-amino`` library for +encoding and decoding all message types. The ``go-amino`` library has the nice +property that it can unmarshal into interface types, but it requires the +relevant types to be registered ahead of type. Registration happens on a +``Codec`` object, so as not to taint the global name space. + +For instance, in ``Basecoin``, we wish to register the ``SendMsg`` and ``IssueMsg`` +types: + +:: + + cdc.RegisterInterface((*sdk.Msg)(nil), nil) + cdc.RegisterConcrete(bank.SendMsg{}, "cosmos-sdk/SendMsg", nil) + cdc.RegisterConcrete(bank.IssueMsg{}, "cosmos-sdk/IssueMsg", nil) + +Note how each concrete type is given a name - these name determine the type's +unique "prefix bytes" during encoding. A registered type will always use the +same prefix-bytes, regardless of what interface it is satisfying. For more +details, see the `go-amino documentation `__. + + +MultiStore +~~~~~~~~~~ + +MultiStore is like a filesystem +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Mounting an IAVLStore +^^^^^^^^^^^^^^^^^^^^^ + +TODO: + +* IAVLStore: Fast balanced dynamic Merkle store. + + * supports iteration. + +* MultiStore: multiple Merkle tree backends in a single store + + * allows using Ethereum Patricia Trie and Tendermint IAVL in same app + +* Provide caching for intermediate state during execution of blocks and transactions (including for iteration) +* Historical state pruning and snapshotting. +* Query proofs (existence, absence, range, etc.) on current and retained historical state. + +Context +------- + +The SDK uses a ``Context`` to propogate common information across functions. The +``Context`` is modelled after the Golang ``context.Context`` object, which has +become ubiquitous in networking middleware and routing applications as a means +to easily propogate request context through handler functions. + +The main information stored in the ``Context`` includes the application +MultiStore (see below), the last block header, and the transaction bytes. +Effectively, the context contains all data that may be necessary for processing +a transaction. + +Many methods on SDK objects receive a context as the first argument. + +Handler +------- + +Transaction processing in the SDK is defined through ``Handler`` functions: + +:: + + type Handler func(ctx Context, tx Tx) Result + +A handler takes a context and a transaction and returns a result. All +information necessary for processing a transaction should be available in the +context. + +While the context holds the entire application state (all referenced from the +root MultiStore), a particular handler only needs a particular kind of access +to a particular store (or two or more). Access to stores is managed using +capabilities keys and mappers. When a handler is initialized, it is passed a +key or mapper that gives it access to the relevant stores. + +:: + + // File: cosmos-sdk/examples/basecoin/app/init_stores.go + app.BaseApp.MountStore(app.capKeyMainStore, sdk.StoreTypeIAVL) + app.accountMapper = auth.NewAccountMapper( + app.capKeyMainStore, // target store + &types.AppAccount{}, // prototype + ) + + // File: cosmos-sdk/examples/basecoin/app/init_handlers.go + app.router.AddRoute("bank", bank.NewHandler(app.accountMapper)) + + // File: cosmos-sdk/x/bank/handler.go + // NOTE: Technically, NewHandler only needs a CoinMapper + func NewHandler(am sdk.AccountMapper) sdk.Handler { + return func(ctx sdk.Context, msg sdk.Msg) sdk.Result { + cm := CoinMapper{am} + ... + } + } + +AnteHandler +----------- + +Handling Fee payment +~~~~~~~~~~~~~~~~~~~~ + +Handling Authentication +~~~~~~~~~~~~~~~~~~~~~~~ + +Accounts and x/auth +------------------- + +sdk.Account +~~~~~~~~~~~ + +auth.BaseAccount +~~~~~~~~~~~~~~~~ + +auth.AccountMapper +~~~~~~~~~~~~~~~~~~ + +Wire codec +---------- + +Why another codec? +~~~~~~~~~~~~~~~~~~ + +vs encoding/json +~~~~~~~~~~~~~~~~ + +vs protobuf +~~~~~~~~~~~ + +KVStore example +--------------- + +Basecoin example +---------------- + +The quintessential SDK application is Basecoin - a simple +multi-asset cryptocurrency. Basecoin consists of a set of +accounts stored in a Merkle tree, where each account may have +many coins. There are two message types: SendMsg and IssueMsg. +SendMsg allows coins to be sent around, while IssueMsg allows a +set of predefined users to issue new coins. diff --git

Once the `QueueElemReDelegation` has reached +maturity, the appropriate unbonding shares are removed from the `Shares` and +`RedelegatingShares` term. + +Note that with the current menchanism a delegator cannot redelegate funds which +are currently redelegating. + +### Cancel Unbonding + +A delegator who is in the process of unbonding from a validator may use the +re-delegate transaction to bond back to the original validator they're +currently unbonding from (and only that validator). If initiated, the delegator +will immediately begin to one again collect rewards from their validator. + + +## Provision Calculations + +Every hour atom provisions are assigned proportionally to the each slashable +bonded token which includes re-delegating atoms but not unbonding tokens. + +Validation provisions are payed directly to a global hold account +(`BondedTokenPool`) and proportions of that hold account owned by each +validator is defined as the `GlobalStakeBonded`. The tokens are payed as bonded +tokens. + +Here, the bonded tokens that a candidate has can be calculated as: + +``` +globalStakeExRate = params.BondedTokenPool / params.IssuedGlobalStakeShares +candidateCoins = candidate.GlobalStakeShares * globalStakeExRate +``` + +If a delegator chooses to add more tokens to a validator then the amount of +validator shares distributed is calculated on exchange rate (aka every +delegators shares do not change value at that moment. The validator's +accounting of distributed shares to delegators must also increased at every +deposit. + +``` +delegatorExRate = validatorCoins / candidate.IssuedDelegatorShares +createShares = coinsDeposited / delegatorExRate +candidate.IssuedDelegatorShares += createShares +``` + +Whenever a validator has new tokens added to it, the `BondedTokenPool` is +increased and must be reflected in the global parameter as well as the +validators `GlobalStakeShares`. This calculation ensures that the worth of the +`GlobalStakeShares` of other validators remains worth a constant absolute +amount of the `BondedTokenPool` + +``` +createdGlobalStakeShares = coinsDeposited / globalStakeExRate +validator.GlobalStakeShares += createdGlobalStakeShares +params.IssuedGlobalStakeShares += createdGlobalStakeShares + +params.BondedTokenPool += coinsDeposited +``` + +Similarly, if a delegator wanted to unbond coins: + +``` +coinsWithdrawn = withdrawlShares * delegatorExRate + +destroyedGlobalStakeShares = coinsWithdrawn / globalStakeExRate +validator.GlobalStakeShares -= destroyedGlobalStakeShares +params.IssuedGlobalStakeShares -= destroyedGlobalStakeShares +params.BondedTokenPool -= coinsWithdrawn +``` + +Note that when an re-delegation occurs the shares to move are placed in an +re-delegation queue where they continue to collect validator provisions until +queue element matures. Although provisions are collected during re-delegation, +re-delegation tokens do not contribute to the voting power of a validator. + +Validator provisions are minted on an hourly basis (the first block of a new +hour). The annual target of between 7% and 20%. The long-term target ratio of +bonded tokens to unbonded tokens is 67%. + +The target annual inflation rate is recalculated for each previsions cycle. The +inflation is also subject to a rate change (positive of negative) depending or +the distance from the desired ratio (67%). The maximum rate change possible is +defined to be 13% per year, however the annual inflation is capped as between +7% and 20%. + +``` +inflationRateChange(0) = 0 +annualInflation(0) = 0.07 + +bondedRatio = bondedTokenPool / totalTokenSupply +AnnualInflationRateChange = (1 - bondedRatio / 0.67) * 0.13 + +annualInflation += AnnualInflationRateChange + +if annualInflation > 0.20 then annualInflation = 0.20 +if annualInflation < 0.07 then annualInflation = 0.07 + +provisionTokensHourly = totalTokenSupply * annualInflation / (365.25*24) +``` + +Because the validators hold a relative bonded share (`GlobalStakeShare`), when +more bonded tokens are added proportionally to all validators the only term +which needs to be updated is the `BondedTokenPool`. So for each previsions +cycle: + +``` +params.BondedTokenPool += provisionTokensHourly +``` + +## Fee Calculations + +Collected fees are pooled globally and divided out passively to validators and +delegators. Each validator has the opportunity to charge commission to the +delegators on the fees collected on behalf of the delegators by the validators. +Fees are paid directly into a global fee pool. Due to the nature of of passive +accounting whenever changes to parameters which affect the rate of fee +distribution occurs, withdrawal of fees must also occur. + + - when withdrawing one must withdrawal the maximum amount they are entitled + too, leaving nothing in the pool, + - when bonding, unbonding, or re-delegating tokens to an existing account a + full withdrawal of the fees must occur (as the rules for lazy accounting + change), + - when a candidate chooses to change the commission on fees, all accumulated + commission fees must be simultaneously withdrawn. + +When the validator is the proposer of the round, that validator (and their +delegators) receives between 1% and 5% of fee rewards, the reserve tax is then +charged, then the remainder is distributed socially by voting power to all +validators including the proposer validator. The amount of proposer reward is +calculated from pre-commits Tendermint messages. All provision rewards are +added to a provision reward pool which validator holds individually. Here note +that `BondedShares` represents the sum of all voting power saved in the +`GlobalState` (denoted `gs`). + +``` +proposerReward = feesCollected * (0.01 + 0.04 + * sumOfVotingPowerOfPrecommitValidators / gs.BondedShares) +candidate.ProposerRewardPool += proposerReward + +reserveTaxed = feesCollected * params.ReserveTax +gs.ReservePool += reserveTaxed + +distributedReward = feesCollected - proposerReward - reserveTaxed +gs.FeePool += distributedReward +gs.SumFeesReceived += distributedReward +gs.RecentFee = distributedReward +``` + +The entitlement to the fee pool held by the each validator can be accounted for +lazily. First we must account for a candidate's `count` and `adjustment`. The +`count` represents a lazy accounting of what that candidates entitlement to the +fee pool would be if there `VotingPower` was to never change and they were to +never withdraw fees. + +``` +candidate.count = candidate.VotingPower * BlockHeight +``` + +Similarly the GlobalState count can be passively calculated whenever needed, +where `BondedShares` is the updated sum of voting powers from all validators. + +``` +gs.count = gs.BondedShares * BlockHeight +``` + +The `adjustment` term accounts for changes in voting power and withdrawals of +fees. The adjustment factor must be persisted with the candidate and modified +whenever fees are withdrawn from the candidate or the voting power of the +candidate changes. When the voting power of the candidate changes the +`Adjustment` factor is increased/decreased by the cumulative difference in the +voting power if the voting power has been the new voting power as opposed to +the old voting power for the entire duration of the blockchain up the previous +block. Each time there is an adjustment change the GlobalState (denoted `gs`) +`Adjustment` must also be updated. + +``` +simplePool = candidate.count / gs.count * gs.SumFeesReceived +projectedPool = candidate.PrevPower * (height-1) + / (gs.PrevPower * (height-1)) * gs.PrevFeesReceived + + candidate.Power / gs.Power * gs.RecentFee + +AdjustmentChange = simplePool - projectedPool +candidate.AdjustmentRewardPool += AdjustmentChange +gs.Adjustment += AdjustmentChange +``` + +Every instance that the voting power changes, information about the state of +the validator set during the change must be recorded as a `powerChange` for +other validators to run through. Before any validator modifies its voting power +it must first run through the above calculation to determine the change in +their `caandidate.AdjustmentRewardPool` for all historical changes in the set +of `powerChange` which they have not yet synced to. The set of all +`powerChange` may be trimmed from its oldest members once all validators have +synced past the height of the oldest `powerChange`. This trim procedure will +occur on an epoch basis. + +```golang +type powerChange struct { + height int64 // block height at change + power rational.Rat // total power at change + prevpower rational.Rat // total power at previous height-1 + feesin coins.Coin // fees in at block height + prevFeePool coins.Coin // total fees in at previous block height +} +``` + +Note that the adjustment factor may result as negative if the voting power of a +different candidate has decreased. + +``` +candidate.AdjustmentRewardPool += withdrawn +gs.Adjustment += withdrawn +``` + +Now the entitled fee pool of each candidate can be lazily accounted for at +any given block: + +``` +candidate.feePool = candidate.simplePool - candidate.Adjustment +``` + +So far we have covered two sources fees which can be withdrawn from: Fees from +proposer rewards (`candidate.ProposerRewardPool`), and fees from the fee pool +(`candidate.feePool`). However we should note that all fees from fee pool are +subject to commission rate from the owner of the candidate. These next +calculations outline the math behind withdrawing fee rewards as either a +delegator to a candidate providing commission, or as the owner of a candidate +who is receiving commission. + +### Calculations For Delegators and Candidates + +The same mechanism described to calculate the fees which an entire validator is +entitled to is be applied to delegator level to determine the entitled fees for +each delegator and the candidates entitled commission from `gs.FeesPool` and +`candidate.ProposerRewardPool`. + +The calculations are identical with a few modifications to the parameters: + - Delegator's entitlement to `gs.FeePool`: + - entitled party voting power should be taken as the effective voting power + after commission is retrieved, + `bond.Shares/candidate.TotalDelegatorShares * candidate.VotingPower * (1 - candidate.Commission)` + - Delegator's entitlement to `candidate.ProposerFeePool` + - global power in this context is actually shares + `candidate.TotalDelegatorShares` + - entitled party voting power should be taken as the effective shares after + commission is retrieved, `bond.Shares * (1 - candidate.Commission)` + - Candidate's commission entitlement to `gs.FeePool` + - entitled party voting power should be taken as the effective voting power + of commission portion of total voting power, + `candidate.VotingPower * candidate.Commission` + - Candidate's commission entitlement to `candidate.ProposerFeePool` + - global power in this context is actually shares + `candidate.TotalDelegatorShares` + - entitled party voting power should be taken as the of commission portion + of total delegators shares, + `candidate.TotalDelegatorShares * candidate.Commission` + +For more implementation ideas see spreadsheet `spec/AbsoluteFeeDistrModel.xlsx` + +As mentioned earlier, every time the voting power of a delegator bond is +changing either by unbonding or further bonding, all fees must be +simultaneously withdrawn.

Once the `QueueElemReDelegation` has reached +maturity, the appropriate unbonding shares are removed from the `Shares` and +`RedelegatingShares` term. + +Note that with the current menchanism a delegator cannot redelegate funds which +are currently redelegating. + +---------------------------------------------- + +## Provision Calculations + +Every hour atom provisions are assigned proportionally to the each slashable +bonded token which includes re-delegating atoms but not unbonding tokens. + +Validation provisions are payed directly to a global hold account +(`BondedTokenPool`) and proportions of that hold account owned by each +validator is defined as the `GlobalStakeBonded`. The tokens are payed as bonded +tokens. + +Here, the bonded tokens that a candidate has can be calculated as: + +``` +globalStakeExRate = params.BondedTokenPool / params.IssuedGlobalStakeShares +candidateCoins = candidate.GlobalStakeShares * globalStakeExRate +``` + +If a delegator chooses to add more tokens to a validator then the amount of +validator shares distributed is calculated on exchange rate (aka every +delegators shares do not change value at that moment.

Although provisions are collected during re-delegation, +re-delegation tokens do not contribute to the voting power of a validator. + +Validator provisions are minted on an hourly basis (the first block of a new +hour). The annual target of between 7% and 20%. The long-term target ratio of +bonded tokens to unbonded tokens is 67%. + +The target annual inflation rate is recalculated for each previsions cycle. The +inflation is also subject to a rate change (positive of negative) depending or +the distance from the desired ratio (67%).

So for each previsions +cycle: + +``` +params.BondedTokenPool += provisionTokensHourly +``` + +## Fee Calculations + +Collected fees are pooled globally and divided out passively to validators and +delegators. Each validator has the opportunity to charge commission to the +delegators on the fees collected on behalf of the delegators by the validators. +Fees are paid directly into a global fee pool.

The amount of proposer reward is +calculated from pre-commits Tendermint messages. All provision rewards are +added to a provision reward pool which validator holds individually.

The adjustment factor must be persisted with the candidate and modified +whenever fees are withdrawn from the candidate or the voting power of the +candidate changes. When the voting power of the candidate changes the +`Adjustment` factor is increased/decreased by the cumulative difference in the +voting power if the voting power has been the new voting power as opposed to +the old voting power for the entire duration of the blockchain up the previous +block. Each time there is an adjustment change the GlobalState (denoted `gs`) +`Adjustment` must also be updated. + +``` +simplePool = candidate.count / gs.count * gs.SumFeesReceived +projectedPool = candidate.PrevPower * (height-1) + / (gs.PrevPower * (height-1)) * gs.PrevFeesReceived + + candidate.Power / gs.Power * gs.RecentFee + +AdjustmentChange = simplePool - projectedPool +candidate.AdjustmentRewardPool += AdjustmentChange +gs.Adjustment += AdjustmentChange +``` + +Every instance that the voting power changes, information about the state of +the validator set during the change must be recorded as a `powerChange` for +other validators to run through. Before any validator modifies its voting power +it must first run through the above calculation to determine the change in +their `caandidate.AdjustmentRewardPool` for all historical changes in the set +of `powerChange` which they have not yet synced to. The set of all +`powerChange` may be trimmed from its oldest members once all validators have +synced past the height of the oldest `powerChange`. This trim procedure will +occur on an epoch basis. + +```golang +type powerChange struct { + height int64 // block height at change + power rational.Rat // total power at change + prevpower rational.Rat // total power at previous height-1 + feesin coins.Coin // fees in at block height + prevFeePool coins.Coin // total fees in at previous block height +} +``` + +Note that the adjustment factor may result as negative if the voting power of a +different candidate has decreased. + +``` +candidate.AdjustmentRewardPool += withdrawn +gs.Adjustment += withdrawn +``` + +Now the entitled fee pool of each candidate can be lazily accounted for at +any given block: + +``` +candidate.feePool = candidate.simplePool - candidate.Adjustment +``` + +So far we have covered two sources fees which can be withdrawn from: Fees from +proposer rewards (`candidate.ProposerRewardPool`), and fees from the fee pool +(`candidate.feePool`).

It is operated and secured by an +open and globally decentralized set of validators. Tendermint consensus is a +Byzantine fault-tolerant distributed protocol that involves all validators in +the process of exchanging protocol messages in the production of each block. To +avoid Nothing-at-Stake problem, a validator in Tendermint needs to lock up +coins in a bond deposit. Tendermint protocol messages are signed by the +validator's private key, and this is a basis for Tendermint strict +accountability that allows punishing misbehaving validators by slashing +(burning) their bonded Atoms. On the other hand, validators are rewarded for +their service of securing blockchain network by the inflationary provisions and +transactions fees. This incentives correct behavior of the validators and +provides the economic security of the network. + +The native token of the Cosmos Hub is called Atom; becoming a validator of the +Cosmos Hub requires holding Atoms. However, not all Atom holders are validators +of the Cosmos Hub. More precisely, there is a selection process that determines +the validator set as a subset of all validator candidates (Atom holders that +wants to become a validator). The other option for Atom holder is to delegate +their atoms to validators, i.e., being a delegator. A delegator is an Atom +holder that has bonded its Atoms by delegating it to a validator (or validator +candidate). By bonding Atoms to secure the network (and taking a risk of being +slashed in case of misbehaviour), a user is rewarded with inflationary +provisions and transaction fees proportional to the amount of its bonded Atoms. +The Cosmos Hub is designed to efficiently facilitate a small numbers of +validators (hundreds), and large numbers of delegators (tens of thousands). +More precisely, it is the role of the Staking module of the Cosmos Hub to +support various staking functionality including validator set selection, +delegating, bonding and withdrawing Atoms, and the distribution of inflationary +provisions and transaction fees. + +## Basic Terms and Definitions + +* Cosmsos Hub - a Tendermint-based Proof of Stake blockchain system +* Atom - native token of the Cosmsos Hub +* Atom holder - an entity that holds some amount of Atoms +* Candidate - an Atom holder that is actively involved in the Tendermint + blockchain protocol (running Tendermint Full Node (TODO: add link to Full + Node definition) and is competing with other candidates to be elected as a + validator (TODO: add link to Validator definition)) +* Validator - a candidate that is currently selected among a set of candidates + to be able to sign protocol messages in the Tendermint consensus protocol +* Delegator - an Atom holder that has bonded some of its Atoms by delegating + them to a validator (or a candidate) +* Bonding Atoms - a process of locking Atoms in a bond deposit (putting Atoms + under protocol control). Atoms are always bonded through a validator (or + candidate) process. Bonded atoms can be slashed (burned) in case a validator + process misbehaves (does not behave according to the protocol specification). + Atom holders can regain access to their bonded Atoms if they have not been + slashed by waiting an Unbonding period. +* Unbonding period - a period of time after which Atom holder gains access to + its bonded Atoms (they can be withdrawn to a user account) or they can be + re-delegated. +* Inflationary provisions - inflation is the process of increasing the Atom supply. + Atoms are periodically created on the Cosmos Hub and issued to bonded Atom holders. + The goal of inflation is to incentize most of the Atoms in existence to be bonded. +* Transaction fees - transaction fee is a fee that is included in a Cosmsos Hub + transaction. The fees are collected by the current validator set and + distributed among validators and delegators in proportion to their bonded + Atom share. +* Commission fee - a fee taken from the transaction fees by a validator for + their service + +## The pool and the share + +At the core of the Staking module is the concept of a pool which denotes a +collection of Atoms contributed by different Atom holders. There are two global +pools in the Staking module: the bonded pool and unbonding pool. Bonded Atoms +are part of the global bonded pool. If a candidate or delegator wants to unbond +its Atoms, those Atoms are moved to the the unbonding pool for the duration of +the unbonding period. In the Staking module, a pool is a logical concept, i.e., +there is no pool data structure that would be responsible for managing pool +resources. Instead, it is managed in a distributed way. More precisely, at the +global level, for each pool, we track only the total amount of bonded or unbonded +Atoms and the current amount of issued shares. A share is a unit of Atom distribution +and the value of the share (share-to-atom exchange rate) changes during +system execution. The share-to-atom exchange rate can be computed as: + +`share-to-atom-exchange-rate = size of the pool / ammount of issued shares` + +Then for each validator candidate (in a per candidate data structure) we keep track of +the amount of shares the candidate owns in a pool. At any point in time, +the exact amount of Atoms a candidate has in the pool can be computed as the +number of shares it owns multiplied with the current share-to-atom exchange rate: + +`candidate-coins = candidate.Shares * share-to-atom-exchange-rate` + +The benefit of such accounting of the pool resources is the fact that a +modification to the pool from bonding/unbonding/slashing/provisioning of +Atoms affects only global data (size of the pool and the number of shares) and +not the related validator/candidate data structure, i.e., the data structure of +other validators do not need to be modified. This has the advantage that +modifying global data is much cheaper computationally than modifying data of +every validator. Let's explain this further with several small examples: + +We consider initially 4 validators p1, p2, p3 and p4, and that each validator +has bonded 10 Atoms to the bonded pool. Furthermore, let's assume that we have +issued initially 40 shares (note that the initial distribution of the shares, +i.e., share-to-atom exchange rate can be set to any meaningful value), i.e., +share-to-atom-ex-rate = 1 atom per share. Then at the global pool level we +have, the size of the pool is 40 Atoms, and the amount of issued shares is +equal to 40. And for each validator we store in their corresponding data +structure that each has 10 shares of the bonded pool. Now lets assume that the +validator p4 starts process of unbonding of 5 shares. Then the total size of +the pool is decreased and now it will be 35 shares and the amount of Atoms is +35 . Note that the only change in other data structures needed is reducing the +number of shares for a validator p4 from 10 to 5. + +Let's consider now the case where a validator p1 wants to bond 15 more atoms to +the pool. Now the size of the pool is 50, and as the exchange rate hasn't +changed (1 share is still worth 1 Atom), we need to create more shares, i.e. we +now have 50 shares in the pool in total. Validators p2, p3 and p4 still have +(correspondingly) 10, 10 and 5 shares each worth of 1 atom per share, so we +don't need to modify anything in their corresponding data structures. But p1 +now has 25 shares, so we update the amount of shares owned by p1 in its +data structure. Note that apart from the size of the pool that is in Atoms, all +other data structures refer only to shares. + +Finally, let's consider what happens when new Atoms are created and added to +the pool due to inflation. Let's assume that the inflation rate is 10 percent +and that it is applied to the current state of the pool. This means that 5 +Atoms are created and added to the pool and that each validator now +proportionally increase it's Atom count. Let's analyse how this change is +reflected in the data structures. First, the size of the pool is increased and +is now 55 atoms. As a share of each validator in the pool hasn't changed, this +means that the total number of shares stay the same (50) and that the amount of +shares of each validator stays the same (correspondingly 25, 10, 10, 5). But +the exchange rate has changed and each share is now worth 55/50 Atoms per +share, so each validator has effectively increased amount of Atoms it has. So +validators now have (correspondingly) 55/2, 55/5, 55/5 and 55/10 Atoms. + +The concepts of the pool and its shares is at the core of the accounting in the +Staking module. It is used for managing the global pools (such as bonding and +unbonding pool), but also for distribution of Atoms between validator and its +delegators (we will explain this in section X). + +#### Delegator shares + +A candidate is, depending on it's status, contributing Atoms to either the +bonded or unbonding pool, and in return gets some amount of (global) pool +shares. Note that not all those Atoms (and respective shares) are owned by the +candidate as some Atoms could be delegated to a candidate. The mechanism for +distribution of Atoms (and shares) between a candidate and it's delegators is +based on a notion of delegator shares. More precisely, every candidate is +issuing (local) delegator shares (`Candidate.IssuedDelegatorShares`) that +represents some portion of global shares managed by the candidate +(`Candidate.GlobalStakeShares`). The principle behind managing delegator shares +is the same as described in [Section](#The pool and the share). We now +illustrate it with an example. + +Let's consider 4 validators p1, p2, p3 and p4, and assume that each validator +has bonded 10 Atoms to the bonded pool. Furthermore, let's assume that we have +issued initially 40 global shares, i.e., that +`share-to-atom-exchange-rate = 1 atom per share`. So we will set +`GlobalState.BondedPool = 40` and `GlobalState.BondedShares = 40` and in the +Candidate data structure of each validator `Candidate.GlobalStakeShares = 10`. +Furthermore, each validator issued 10 delegator shares which are initially +owned by itself, i.e., `Candidate.IssuedDelegatorShares = 10`, where +`delegator-share-to-global-share-ex-rate = 1 global share per delegator share`. +Now lets assume that a delegator d1 delegates 5 atoms to a validator p1 and +consider what are the updates we need to make to the data structures. First, +`GlobalState.BondedPool = 45` and `GlobalState.BondedShares = 45`. Then, for +validator p1 we have `Candidate.GlobalStakeShares = 15`, but we also need to +issue also additional delegator shares, i.e., +`Candidate.IssuedDelegatorShares = 15` as the delegator d1 now owns 5 delegator +shares of validator p1, where each delegator share is worth 1 global shares, +i.e, 1 Atom. Lets see now what happens after 5 new Atoms are created due to +inflation. In that case, we only need to update `GlobalState.BondedPool` which +is now equal to 50 Atoms as created Atoms are added to the bonded pool. Note +that the amount of global and delegator shares stay the same but they are now +worth more as share-to-atom-exchange-rate is now worth 50/45 Atoms per share. +Therefore, a delegator d1 now owns: + +`delegatorCoins = 5 (delegator shares) * 1 (delegator-share-to-global-share-ex-rate) * 50/45 (share-to-atom-ex-rate) = 5.55 Atoms` + +### Inflation provisions + +Validator provisions are minted on an hourly basis (the first block of a new +hour). The annual target of between 7% and 20%. The long-term target ratio of +bonded tokens to unbonded tokens is 67%. + +The target annual inflation rate is recalculated for each provisions cycle. The +inflation is also subject to a rate change (positive or negative) depending on +the distance from the desired ratio (67%). The maximum rate change possible is +defined to be 13% per year, however the annual inflation is capped as between +7% and 20%. + +```go +inflationRateChange(0) = 0 +GlobalState.Inflation(0) = 0.07 + +bondedRatio = GlobalState.BondedPool / GlobalState.TotalSupply +AnnualInflationRateChange = (1 - bondedRatio / 0.67) * 0.13 + +annualInflation += AnnualInflationRateChange + +if annualInflation > 0.20 then GlobalState.Inflation = 0.20 +if annualInflation < 0.07 then GlobalState.Inflation = 0.07 + +provisionTokensHourly = GlobalState.TotalSupply * GlobalState.Inflation / (365.25*24) +``` + +Because the validators hold a relative bonded share (`GlobalStakeShares`), when +more bonded tokens are added proportionally to all validators, the only term +which needs to be updated is the `GlobalState.BondedPool`. So for each +provisions cycle: + +```go +GlobalState.BondedPool += provisionTokensHourly +``` diff --git a/docs/spec/staking/state.md b/docs/spec/staking/state.md index 72cda1bb4581..2bcf13dea020 100644 --- a/docs/spec/staking/state.md +++ b/docs/spec/staking/state.md @@ -1,147 +1,204 @@ -## State - -### Pool - - index: n/a single-record -The pool is a space for all dynamic global state of the Cosmos Hub.

-If you want to see some examples, take a look at the [examples/basecoin](/examples/basecoin) directory. - -## Design Goals - -The design of the Cosmos SDK is based on the principles of "capabilities systems". - -## Capabilities systems - -### Need for module isolation -### Capability is implied permission -### TODO Link to thesis - -## Tx & Msg - -The SDK distinguishes between transactions (Tx) and messages -(Msg). A Tx is a Msg wrapped with authentication and fee data. - -### Messages - -Users can create messages containing arbitrary information by -implementing the `Msg` interface: - -```go -type Msg interface { - - // Return the message type. - // Must be alphanumeric or empty. - Type() string - - // Get the canonical byte representation of the Msg. - GetSignBytes() []byte - - // ValidateBasic does a simple validation check that - // doesn't require access to any other information. - ValidateBasic() error - - // Signers returns the addrs of signers that must sign. - // CONTRACT: All signatures must be present to be valid. - // CONTRACT: Returns addrs in some deterministic order. - GetSigners() []Address -} - -``` - -Messages must specify their type via the `Type()` method. The type should -correspond to the messages handler, so there can be many messages with the same -type. - -Messages must also specify how they are to be authenticated. The `GetSigners()` -method return a list of addresses that must sign the message, while the -`GetSignBytes()` method returns the bytes that must be signed for a signature -to be valid. - -Addresses in the SDK are arbitrary byte arrays that are hex-encoded when -displayed as a string or rendered in JSON. - -Messages can specify basic self-consistency checks using the `ValidateBasic()` -method to enforce that message contents are well formed before any actual logic -begins. - -For instance, the `Basecoin` message types are defined in `x/bank/tx.go`: - -```go -type MsgSend struct { - Inputs []Input `json:"inputs"` - Outputs []Output `json:"outputs"` -} - -type MsgIssue struct { - Banker sdk.Address `json:"banker"` - Outputs []Output `json:"outputs"` -} -``` - -Each specifies the addresses that must sign the message: - -```go -func (msg MsgSend) GetSigners() []sdk.Address { - addrs := make([]sdk.Address, len(msg.Inputs)) - for i, in := range msg.Inputs { - addrs[i] = in.Address - } - return addrs -} - -func (msg MsgIssue) GetSigners() []sdk.Address { - return []sdk.Address{msg.Banker} -} -``` - -### Transactions - -A transaction is a message with additional information for authentication: - -```go -type Tx interface { - - GetMsg() Msg - - // Signatures returns the signature of signers who signed the Msg. - // CONTRACT: Length returned is same as length of - // pubkeys returned from MsgKeySigners, and the order - // matches. - // CONTRACT: If the signature is missing (ie the Msg is - // invalid), then the corresponding signature is - // .Empty(). - GetSignatures() []StdSignature -} -``` - -The `tx.GetSignatures()` method returns a list of signatures, which must match -the list of addresses returned by `tx.Msg.GetSigners()`. The signatures come in -a standard form: - -```go -type StdSignature struct { - crypto.PubKey // optional - crypto.Signature - Sequence int64 -} -``` - -It contains the signature itself, as well as the corresponding account's -sequence number. The sequence number is expected to increment every time a -message is signed by a given account. This prevents "replay attacks", where -the same message could be executed over and over again. - -The `StdSignature` can also optionally include the public key for verifying the -signature. An application can store the public key for each address it knows -about, making it optional to include the public key in the transaction. In the -case of Basecoin, the public key only needs to be included in the first -transaction send by a given account - after that, the public key is forever -stored by the application and can be left out of transactions. - -The address responsible for paying the transactions fee is the first address -returned by msg.GetSigners(). The convenience function `FeePayer(tx Tx)` is provided -to return this. - -The standard way to create a transaction from a message is to use the `StdTx`: - -```go -type StdTx struct { - Msg - Signatures []StdSignature -} -``` - -### Encoding and Decoding Transactions - -Messages and transactions are designed to be generic enough for developers to -specify their own encoding schemes. This enables the SDK to be used as the -framwork for constructing already specified cryptocurrency state machines, for -instance Ethereum. - -When initializing an application, a developer must specify a `TxDecoder` -function which determines how an arbitrary byte array should be unmarshalled -into a `Tx`: - -```go -type TxDecoder func(txBytes []byte) (Tx, error) -``` - -In `Basecoin`, we use the Tendermint wire format and the `go-amino` library for -encoding and decoding all message types. The `go-amino` library has the nice -property that it can unmarshal into interface types, but it requires the -relevant types to be registered ahead of type. Registration happens on a -`Codec` object, so as not to taint the global name space. - -For instance, in `Basecoin`, we wish to register the `MsgSend` and `MsgIssue` -types: - -```go -cdc.RegisterInterface((*sdk.Msg)(nil), nil) -cdc.RegisterConcrete(bank.MsgSend{}, "cosmos-sdk/MsgSend", nil) -cdc.RegisterConcrete(bank.MsgIssue{}, "cosmos-sdk/MsgIssue", nil) -``` - -Note how each concrete type is given a name - these name determine the type's -unique "prefix bytes" during encoding. A registered type will always use the -same prefix-bytes, regardless of what interface it is satisfying. For more -details, see the [go-amino documentation](https://github.com/tendermint/go-amino/blob/develop). - - -## Storage - -### MultiStore - -MultiStore is like a root filesystem of an operating system, except -all the entries are fully Merkleized. You mount onto a MultiStore -any number of Stores. Currently only KVStores are supported, but in -the future we may support more kinds of stores, such as a HeapStore -or a NDStore for multidimensional storage. - -The MultiStore as well as all mounted stores provide caching (aka -cache-wrapping) for intermediate state (aka software transactional -memory) during the execution of transactions. In the case of the -KVStore, this also works for iterators. For example, after running -the app's AnteHandler, the MultiStore is cache-wrapped (and each -store is also cache-wrapped) so that should processing of the -transaction fail, at least the transaction fees are paid and -sequence incremented. - -The MultiStore as well as all stores support (or will support) -historical state pruning and snapshotting and various kinds of -queries with proofs. - -### KVStore - -Here we'll focus on the IAVLStore, which is a kind of KVStore. - -IAVLStore is a fast balanced dynamic Merkle store that also supports -iteration, and of course cache-wrapping, state pruning, and various -queries with proofs, such as proofs of existence, absence, range, -and so on. - -Here's how you mount them to a MultiStore. - -```go -mainDB, catDB := dbm.NewMemDB(), dbm.NewMemDB() -fooKey := sdk.NewKVStoreKey("foo") -barKey := sdk.NewKVStoreKey("bar") -catKey := sdk.NewKVStoreKey("cat") -ms := NewCommitMultiStore(mainDB) -ms.MountStoreWithDB(fooKey, sdk.StoreTypeIAVL, nil) -ms.MountStoreWithDB(barKey, sdk.StoreTypeIAVL, nil) -ms.MountStoreWithDB(catKey, sdk.StoreTypeIAVL, catDB) -``` - -In the example above, all IAVL nodes (inner and leaf) will be stored -in mainDB with the prefix of "s/k:foo/" and "s/k:bar/" respectively, -thus sharing the mainDB. All IAVL nodes (inner and leaf) for the -cat KVStore are stored separately in catDB with the prefix of -"s/\_/". The "s/k:KEY/" and "s/\_/" prefixes are there to -disambiguate store items from other items of non-storage concern. - - -## Context - -The SDK uses a `Context` to propogate common information across functions. The -`Context` is modeled after the Golang `context.Context` object, which has -become ubiquitous in networking middleware and routing applications as a means -to easily propogate request context through handler functions. - -The main information stored in the `Context` includes the application -MultiStore (see below), the last block header, and the transaction bytes. -Effectively, the context contains all data that may be necessary for processing -a transaction. - -Many methods on SDK objects receive a context as the first argument. - -## Handler - -Transaction processing in the SDK is defined through `Handler` functions: - -```go -type Handler func(ctx Context, tx Tx) Result -``` - -A handler takes a context and a transaction and returns a result. All -information necessary for processing a transaction should be available in the -context. - -While the context holds the entire application state (all referenced from the -root MultiStore), a particular handler only needs a particular kind of access -to a particular store (or two or more). Access to stores is managed using -capabilities keys and mappers. When a handler is initialized, it is passed a -key or mapper that gives it access to the relevant stores. - -```go -// File: cosmos-sdk/examples/basecoin/app/init_stores.go -app.BaseApp.MountStore(app.capKeyMainStore, sdk.StoreTypeIAVL) -app.accountMapper = auth.NewAccountMapper( - app.capKeyMainStore, // target store - &types.AppAccount{}, // prototype -) - -// File: cosmos-sdk/examples/basecoin/app/init_handlers.go -app.router.AddRoute("bank", bank.NewHandler(app.accountMapper)) - -// File: cosmos-sdk/x/bank/handler.go -// NOTE: Technically, NewHandler only needs a CoinMapper -func NewHandler(am sdk.AccountMapper) sdk.Handler { - return func(ctx sdk.Context, msg sdk.Msg) sdk.Result { - cm := CoinMapper{am} - ... - } -} -``` - -## AnteHandler - -### Handling Fee payment -### Handling Authentication - -## Accounts and x/auth - -### sdk.Account -### auth.BaseAccount -### auth.AccountMapper - -## Wire codec - -### Why another codec? -### vs encoding/json -### vs protobuf - -## KVStore example - -## Basecoin example - -The quintessential SDK application is Basecoin - a simple -multi-asset cryptocurrency. Basecoin consists of a set of -accounts stored in a Merkle tree, where each account may have -many coins. There are two message types: MsgSend and MsgIssue. -MsgSend allows coins to be sent around, while MsgIssue allows a -set of predefined users to issue new coins. - -## Conclusion diff --git a/docs/guides/Makefile b/docs/guides/Makefile deleted file mode 100644 index f4bccf3bd32b..000000000000 --- a/docs/guides/Makefile +++ /dev/null @@ -1,20 +0,0 @@ -# Minimal makefile for Sphinx documentation -# - -# You can set these variables from the command line. -SPHINXOPTS = -SPHINXBUILD = python -msphinx -SPHINXPROJ = Cosmos-SDK -SOURCEDIR = . -BUILDDIR = _build - -# Put it first so that "make" without argument is like "make help". -help: - @$(SPHINXBUILD) -M help "$(SOURCEDIR)" "$(BUILDDIR)" $(SPHINXOPTS) $(O) - -.PHONY: help Makefile - -# Catch-all target: route all unknown targets to Sphinx using the new -# "make mode" option. $(O) is meant as a shortcut for $(SPHINXOPTS). -%: Makefile - @$(SPHINXBUILD) -M $@ "$(SOURCEDIR)" "$(BUILDDIR)" $(SPHINXOPTS) $(O) \ No newline at end of file diff --git a/docs/guides/conf.py b/docs/guides/conf.py deleted file mode 100644 index 73a0220fd5f3..000000000000 --- a/docs/guides/conf.py +++ /dev/null @@ -1,170 +0,0 @@ -# -*- coding: utf-8 -*- -# -# Cosmos-SDK documentation build configuration file, created by -# sphinx-quickstart on Fri Sep 1 21:37:02 2017. -# -# This file is execfile()d with the current directory set to its -# containing dir. -# -# Note that not all possible configuration values are present in this -# autogenerated file. -# -# All configuration values have a default; values that are commented out -# serve to show the default. - -# If extensions (or modules to document with autodoc) are in another directory, -# add these directories to sys.path here.

Each account -contains a public key, a balance in many different coin denominations, -and a strictly increasing sequence number for replay protection. This -type of account was directly inspired by accounts in Ethereum, and is -unlike Bitcoin's use of Unspent Transaction Outputs (UTXOs). Note -Basecoin is a multi-asset cryptocurrency, so each account can have many -different kinds of tokens. - -:: - - type Account struct { - PubKey crypto.PubKey `json:"pub_key"` // May be nil, if not known. - Sequence int `json:"sequence"` - Balance Coins `json:"coins"` - } - - type Coins []Coin - - type Coin struct { - Denom string `json:"denom"` - Amount int64 `json:"amount"` - } - -If you want to add more coins to a blockchain, you can do so manually in -the ``~/.basecoin/genesis.json`` before you start the blockchain for the -first time. - -Accounts are serialized and stored in a Merkle tree under the key -``base/a/
``, where ``
`` is the address of the account. -Typically, the address of the account is the 20-byte ``RIPEMD160`` hash -of the public key, but other formats are acceptable as well, as defined -in the `Tendermint crypto -library `__. The Merkle tree -used in Basecoin is a balanced, binary search tree, which we call an -`IAVL tree `__. - -Transactions -~~~~~~~~~~~~ - -Basecoin defines a transaction type, the ``SendTx``, which allows tokens -to be sent to other accounts. The ``SendTx`` takes a list of inputs and -a list of outputs, and transfers all the tokens listed in the inputs -from their corresponding accounts to the accounts listed in the output. -The ``SendTx`` is structured as follows: - -:: - - type SendTx struct { - Gas int64 `json:"gas"` - Fee Coin `json:"fee"` - Inputs []TxInput `json:"inputs"` - Outputs []TxOutput `json:"outputs"` - } - - type TxInput struct { - Address []byte `json:"address"` // Hash of the PubKey - Coins Coins `json:"coins"` // - Sequence int `json:"sequence"` // Must be 1 greater than the last committed TxInput - Signature crypto.Signature `json:"signature"` // Depends on the PubKey type and the whole Tx - PubKey crypto.PubKey `json:"pub_key"` // Is present iff Sequence == 0 - } - - type TxOutput struct { - Address []byte `json:"address"` // Hash of the PubKey - Coins Coins `json:"coins"` // - } - -Note the ``SendTx`` includes a field for ``Gas`` and ``Fee``. The -``Gas`` limits the total amount of computation that can be done by the -transaction, while the ``Fee`` refers to the total amount paid in fees. -This is slightly different from Ethereum's concept of ``Gas`` and -``GasPrice``, where ``Fee = Gas x GasPrice``. In Basecoin, the ``Gas`` -and ``Fee`` are independent, and the ``GasPrice`` is implicit. - -In Basecoin, the ``Fee`` is meant to be used by the validators to inform -the ordering of transactions, like in Bitcoin. And the ``Gas`` is meant -to be used by the application plugin to control its execution. There is -currently no means to pass ``Fee`` information to the Tendermint -validators, but it will come soon... - -Note also that the ``PubKey`` only needs to be sent for -``Sequence == 0``. After that, it is stored under the account in the -Merkle tree and subsequent transactions can exclude it, using only the -``Address`` to refer to the sender. Ethereum does not require public -keys to be sent in transactions as it uses a different elliptic curve -scheme which enables the public key to be derived from the signature -itself. - -Finally, note that the use of multiple inputs and multiple outputs -allows us to send many different types of tokens between many different -accounts at once in an atomic transaction. Thus, the ``SendTx`` can -serve as a basic unit of decentralized exchange. When using multiple -inputs and outputs, you must make sure that the sum of coins of the -inputs equals the sum of coins of the outputs (no creating money), and -that all accounts that provide inputs have signed the transaction. - -Clean Up --------- - -**WARNING:** Running these commands will wipe out any existing -information in both the ``~/.basecli`` and ``~/.basecoin`` directories, -including private keys. - -To remove all the files created and refresh your environment (e.g., if -starting this tutorial again or trying something new), the following -commands are run: - -:: - - basecli reset_all - rm -rf ~/.basecoin - -In this guide, we introduced the ``basecoin`` and ``basecli`` tools, -demonstrated how to start a new basecoin blockchain and how to send -tokens between accounts, and discussed the underlying data types for -accounts and transactions, specifically the ``Account`` and the -``SendTx``. diff --git a/docs/old/basecoin/extensions.rst b/docs/old/basecoin/extensions.rst deleted file mode 100644 index 6f31222deffa..000000000000 --- a/docs/old/basecoin/extensions.rst +++ /dev/null @@ -1,215 +0,0 @@ -Basecoin Extensions -=================== - -TODO: re-write for extensions - -In the `previous guide `__, we saw how to use the -``basecoin`` tool to start a blockchain and the ``basecli`` tools to -send transactions.

The ``Name`` field in the -``AppTx`` refers to the particular plugin which should process the -transaction, and the ``Data`` field of the ``AppTx`` is the data to be -forwarded to the plugin for processing. - -Note the ``AppTx`` also has a ``Gas`` and ``Fee``, with the same meaning -as for the ``SendTx``. It also includes a single ``TxInput``, which -specifies the sender of the transaction, and some coins that can be -forwarded to the plugin as well. - -Plugins -------- - -A plugin is simply a Go package that implements the ``Plugin`` -interface: - -:: - - type Plugin interface { - - // Name of this plugin, should be short. - Name() string - - // Run a transaction from ABCI DeliverTx - RunTx(store KVStore, ctx CallContext, txBytes []byte) (res abci.Result) - - // Other ABCI message handlers - SetOption(store KVStore, key string, value string) (log string) - InitChain(store KVStore, vals []*abci.Validator) - BeginBlock(store KVStore, hash []byte, header *abci.Header) - EndBlock(store KVStore, height uint64) (res abci.ResponseEndBlock) - } - - type CallContext struct { - CallerAddress []byte // Caller's Address (hash of PubKey) - CallerAccount *Account // Caller's Account, w/ fee & TxInputs deducted - Coins Coins // The coins that the caller wishes to spend, excluding fees - } - -The workhorse of the plugin is ``RunTx``, which is called when an -``AppTx`` is processed. The ``Data`` from the ``AppTx`` is passed in as -the ``txBytes``, while the ``Input`` from the ``AppTx`` is used to -populate the ``CallContext``. - -Note that ``RunTx`` also takes a ``KVStore`` - this is an abstraction -for the underlying Merkle tree which stores the account data. By passing -this to the plugin, we enable plugins to update accounts in the Basecoin -state directly, and also to store arbitrary other information in the -state. In this way, the functionality and state of a Basecoin-derived -cryptocurrency can be greatly extended.

These files -are where we extend the tool with any new commands and flags we need to -send transactions or queries to our plugin. You define custom ``tx`` and -``query`` subcommands, which are registered in ``main.go`` (avoiding -``init()`` auto-registration, for less magic and more control in the -main executable). - -Finally is ``plugins/counter/counter.go``, where we provide an -implementation of the ``Plugin`` interface. The most important part of -the implementation is the ``RunTx`` method, which determines the meaning -of the data sent along in the ``AppTx``. In our example, we define a new -transaction type, the ``CounterTx``, which we expect to be encoded in -the ``AppTx.Data``, and thus to be decoded in the ``RunTx`` method, and -used to update the plugin state. - -For more examples and inspiration, see our `repository of example -plugins `__. - -Conclusion ----------- - -In this guide, we demonstrated how to create a new plugin and how to -extend the ``basecoin`` tool to start a blockchain with the plugin -enabled and send transactions to it.

This is -mainly to provide a background and general understanding of the -different words and concepts that are used. Other documents will explain -in more detail how to combine these concepts to build a particular -application. - -Transaction ------------ - -A transaction is a packet of binary data that contains all information -to validate and perform an action on the blockchain. The only other data -that it interacts with is the current state of the chain (key-value -store), and it must have a deterministic action. The transaction is the -main piece of one request. - -We currently make heavy use of -`go-amino `__ to -provide binary and json encodings and decodings for ``struct`` or -interface\ ``objects. Here, encoding and decoding operations are designed to operate with interfaces nested any amount times (like an onion!). There is one public``\ TxMapper\` -in the basecoin root package, and all modules can register their own -transaction types there. This allows us to deserialize the entire -transaction in one location (even with types defined in other repos), to -easily embed an arbitrary transaction inside another without specifying -the type, and provide an automatic json representation allowing for -users (or apps) to inspect the chain. - -Note how we can wrap any other transaction, add a fee level, and not -worry about the encoding in our module any more? - -:: - - type Fee struct { - Fee coin.Coin `json:"fee"` - Payer basecoin.Actor `json:"payer"` // the address who pays the fee - Tx basecoin.Tx `json:"tx"` - } - -Context (ctx) -------------- - -As a request passes through the system, it may pick up information such -as the block height the request runs at. In order to carry this information -between modules it is saved to the context. Further, all information -must be deterministic from the context in which the request runs (based -on the transaction and the block it was included in) and can be used to -validate the transaction. - -Data Store ----------- - -In order to provide proofs to Tendermint, we keep all data in one -key-value (kv) store which is indexed with a merkle tree. This allows -for the easy generation of a root hash and proofs for queries without -requiring complex logic inside each module. Standardization of this -process also allows powerful light-client tooling as any store data may -be verified on the fly. - -The largest limitation of the current implemenation of the kv-store is -that interface that the application must use can only ``Get`` and -``Set`` single data points. That said, there are some data structures -like queues and range queries that are available in ``state`` package. -These provide higher-level functionality in a standard format, but have -not yet been integrated into the kv-store interface. - -Isolation ---------- - -One of the main arguments for blockchain is security. So while we -encourage the use of third-party modules, all developers must be -vigilant against security holes. If you use the -`stack `__ -package, it will provide two different types of compartmentalization -security. - -The first is to limit the working kv-store space of each module. When -``DeliverTx`` is called for a module, it is never given the entire data -store, but rather only its own prefixed subset of the store. This is -achieved by prefixing all keys transparently with -`` + 0x0``, using the null byte as a separator. Since the -module name must be a string, no malicious naming scheme can ever lead -to a collision. Inside a module, we can write using any key value we -desire without the possibility that we have modified data belonging to -separate module. - -The second is to add permissions to the transaction context. The -transaction context can specify that the tx has been signed by one or -multiple specific actors. - -A transactions will only be executed if the permission requirements have -been fulfilled. For example the sender of funds must have signed, or 2 -out of 3 multi-signature actors must have signed a joint account. To -prevent the forgery of account signatures from unintended modules each -permission is associated with the module that granted it (in this case -`auth `__), -and if a module tries to add a permission for another module, it will -panic. There is also protection if a module creates a brand new fake -context to trick the downstream modules. Each context enforces the rules -on how to make child contexts, and the stack builder enforces -that the context passed from one level to the next is a valid child of -the original one. - -These security measures ensure that modules can confidently write to -their local section of the database and trust the permissions associated -with the context, without concern of interference from other modules. -(Okay, if you see a bunch of C-code in the module traversing through all -the memory space of the application, then get worried....) - -Handler -------- - -The ABCI interface is handled by ``app``, which translates these data -structures into an internal format that is more convenient, but unable -to travel over the wire. The basic interface for any code that modifies -state is the ``Handler`` interface, which provides four methods: - -:: - - Name() string - CheckTx(ctx Context, store state.KVStore, tx Tx) (Result, error) - DeliverTx(ctx Context, store state.KVStore, tx Tx) (Result, error) - SetOption(l log.Logger, store state.KVStore, module, key, value string) (string, error) - -Note the ``Context``, ``KVStore``, and ``Tx`` as principal carriers of -information. And that Result is always success, and we have a second -error return for errors (which is much more standard golang that -``res.IsErr()``) - -The ``Handler`` interface is designed to be the basis for all modules -that execute transactions, and this can provide a large degree of code -interoperability, much like ``http.Handler`` does in golang web -development. - -Modules -------- - -TODO: update (s/Modules/handlers+mappers+stores/g) & add Msg + Tx (a signed message) - -A module is a set of functionality which should be typically designed as -self-sufficient. Common elements of a module are: - -- transaction types (either end transactions, or transaction wrappers) -- custom error codes -- data models (to persist in the kv-store) -- handler (to handle any end transactions) - -Dispatcher ----------- - -We usually will want to have multiple modules working together, and need -to make sure the correct transactions get to the correct module. So we -have ``coin`` sending money, ``roles`` to create multi-sig accounts, and -``ibc`` for following other chains all working together without -interference. - -We can then register a ``Dispatcher``, which -also implements the ``Handler`` interface. We then register a list of -modules with the dispatcher. Every module has a unique ``Name()``, which -is used for isolating its state space. We use this same name for routing -transactions. Each transaction implementation must be registed with -go-amino via ``TxMapper``, so we just look at the registered name of this -transaction, which should be of the form ``/xxx``. The -dispatcher grabs the appropriate module name from the tx name and routes -it if the module is present. - -This all seems like a bit of magic, but really we're just making use of -go-amino magic that we are already using, rather than add another layer. -For all the transactions to be properly routed, the only thing you need -to remember is to use the following pattern: - -:: - - const ( - NameCoin = "coin" - TypeSend = NameCoin + "/send" - ) - -Permissions ------------ - -TODO: replaces perms with object capabilities/object capability keys -- get rid of IPC - -IPC requires a more complex permissioning system to allow the modules to -have limited access to each other and also to allow more types of -permissions than simple public key signatures. Rather than just use an -address to identify who is performing an action, we can use a more -complex structure: - -:: - - type Actor struct { - ChainID string `json:"chain"` // this is empty unless it comes from a different chain - App string `json:"app"` // the app that the actor belongs to - Address data.Bytes `json:"addr"` // arbitrary app-specific unique id - } - -Here, the ``Actor`` abstracts any address that can authorize actions, -hold funds, or initiate any sort of transaction. It doesn't just have to -be a pubkey on this chain, it could stem from another app (such as -multi-sig account), or even another chain (via IBC) - -``ChainID`` is for IBC, discussed below. Let's focus on ``App`` and -``Address``. For a signature, the App is ``auth``, and any modules can -check to see if a specific public key address signed like this -``ctx.HasPermission(auth.SigPerm(addr))``. However, we can also -authorize a tx with ``roles``, which handles multi-sig accounts, it -checks if there were enough signatures by checking as above, then it can -add the role permission like -``ctx= ctx.WithPermissions(NewPerm(assume.Role))`` - -In addition to the permissions schema, the Actors are addresses just -like public key addresses. So one can create a mulit-sig role, then send -coin there, which can only be moved upon meeting the authorization -requirements from that module. ``coin`` doesn't even know the existence -of ``roles`` and one could build any other sort of module to provide -permissions (like bind the outcome of an election to move coins or to -modify the accounts on a role). - -One idea - not yet implemented - is to provide scopes on the -permissions. Currently, if I sign a transaction to one module, it can -pass it on to any other module over IPC with the same permissions. It -could move coins, vote in an election, or anything else. Ideally, when -signing, one could also specify the scope(s) that this signature -authorizes. The `oauth -protocol `__ also has to deal -with a similar problem, and maybe could provide some inspiration. diff --git a/docs/old/ibc.rst b/docs/old/ibc.rst deleted file mode 100644 index 30b9a16faf91..000000000000 --- a/docs/old/ibc.rst +++ /dev/null @@ -1,424 +0,0 @@ -IBC -=== - -TODO: update in light of latest SDK (this document is currently out of date) - -One of the most exciting elements of the Cosmos Network is the -InterBlockchain Communication (IBC) protocol, which enables -interoperability across different blockchains.

The purpose of IBC is to enable one -blockchain to function as a light-client of another. Since we are using -a classical Byzantine Fault Tolerant consensus algorithm, light-client -verification is cheap and easy: all we have to do is check validator -signatures on the latest block, and verify a Merkle proof of the state. - -In Tendermint, validators agree on a block before processing it. This -means that the signatures and state root for that block aren't included -until the next block. Thus, each block contains a field called -``LastCommit``, which contains the votes responsible for committing the -previous block, and a field in the block header called ``AppHash``, -which refers to the Merkle root hash of the application after processing -the transactions from the previous block. So, if we want to verify the -``AppHash`` from height H, we need the signatures from ``LastCommit`` at -height H+1. (And remember that this ``AppHash`` only contains the -results from all transactions up to and including block H-1) - -Unlike Proof-of-Work, the light-client protocol does not need to -download and check all the headers in the blockchain - the client can -always jump straight to the latest header available, so long as the -validator set has not changed much. If the validator set is changing, -the client needs to track these changes, which requires downloading -headers for each block in which there is a significant change. Here, we -will assume the validator set is constant, and postpone handling -validator set changes for another time. - -Now we can describe exactly how IBC works. Suppose we have two -blockchains, ``chain1`` and ``chain2``, and we want to send some data -from ``chain1`` to ``chain2``. We need to do the following: 1. Register -the details (ie. chain ID and genesis configuration) of ``chain1`` on -``chain2`` 2. Within ``chain1``, broadcast a transaction that creates an -outgoing IBC packet destined for ``chain2`` 3. Broadcast a transaction -to ``chain2`` informing it of the latest state (ie. header and commit -signatures) of ``chain1`` 4. Post the outgoing packet from ``chain1`` to -``chain2``, including the proof that it was indeed committed on -``chain1``. Note ``chain2`` can only verify this proof because it has a -recent header and commit. - -Each of these steps involves a separate IBC transaction type. Let's take -them up in turn. - -IBCRegisterChainTx -~~~~~~~~~~~~~~~~~~ - -The ``IBCRegisterChainTx`` is used to register one chain on another. It -contains the chain ID and genesis configuration of the chain to -register: - -:: - - type IBCRegisterChainTx struct { BlockchainGenesis } - - type BlockchainGenesis struct { ChainID string Genesis string } - -This transaction should only be sent once for a given chain ID, and -successive sends will return an error. - -IBCUpdateChainTx -~~~~~~~~~~~~~~~~ - -The ``IBCUpdateChainTx`` is used to update the state of one chain on -another. It contains the header and commit signatures for some block in -the chain: - -:: - - type IBCUpdateChainTx struct { - Header tm.Header - Commit tm.Commit - } - -In the future, it needs to be updated to include changes to the -validator set as well. Anyone can relay an ``IBCUpdateChainTx``, and -they only need to do so as frequently as packets are being sent or the -validator set is changing. - -IBCPacketCreateTx -~~~~~~~~~~~~~~~~~ - -The ``IBCPacketCreateTx`` is used to create an outgoing packet on one -chain. The packet itself contains the source and destination chain IDs, -a sequence number (i.e. an integer that increments with every message -sent between this pair of chains), a packet type (e.g. coin, data, -etc.), and a payload. - -:: - - type IBCPacketCreateTx struct { - Packet - } - - type Packet struct { - SrcChainID string - DstChainID string - Sequence uint64 - Type string - Payload []byte - } - -We have yet to define the format for the payload, so, for now, it's just -arbitrary bytes. - -One way to think about this is that ``chain2`` has an account on -``chain1``. With a ``IBCPacketCreateTx`` on ``chain1``, we send funds to -that account. Then we can prove to ``chain2`` that there are funds -locked up for it in it's account on ``chain1``. Those funds can only be -unlocked with corresponding IBC messages back from ``chain2`` to -``chain1`` sending the locked funds to another account on ``chain1``. - -IBCPacketPostTx -~~~~~~~~~~~~~~~ - -The ``IBCPacketPostTx`` is used to post an outgoing packet from one -chain to another. It contains the packet and a proof that the packet was -committed into the state of the sending chain: - -:: - - type IBCPacketPostTx struct { - FromChainID string // The immediate source of the packet, not always Packet.SrcChainID - FromChainHeight uint64 // The block height in which Packet was committed, to check Proof Packet - Proof *merkle.IAVLProof - } - -The proof is a Merkle proof in an IAVL tree, our implementation of a -balanced, Merklized binary search tree. It contains a list of nodes in -the tree, which can be hashed together to get the Merkle root hash. This -hash must match the ``AppHash`` contained in the header at -``FromChainHeight + 1`` - -- note the ``+ 1`` is necessary since ``FromChainHeight`` is the height - in which the packet was committed, and the resulting state root is - not included until the next block. - -IBC State -~~~~~~~~~ - -Now that we've seen all the transaction types, let's talk about the -state. Each chain stores some IBC state in its Merkle tree. For each -chain being tracked by our chain, we store: - -- Genesis configuration -- Latest state -- Headers for recent heights - -We also store all incoming (ingress) and outgoing (egress) packets. - -The state of a chain is updated every time an ``IBCUpdateChainTx`` is -committed. New packets are added to the egress state upon -``IBCPacketCreateTx``. New packets are added to the ingress state upon -``IBCPacketPostTx``, assuming the proof checks out. - -Merkle Queries --------------- - -The Basecoin application uses a single Merkle tree that is shared across -all its state, including the built-in accounts state and all plugin -state. For this reason, it's important to use explicit key names and/or -hashes to ensure there are no collisions. - -We can query the Merkle tree using the ABCI Query method. If we pass in -the correct key, it will return the corresponding value, as well as a -proof that the key and value are contained in the Merkle tree. - -The results of a query can thus be used as proof in an -``IBCPacketPostTx``. - -Relay ------ - -While we need all these packet types internally to keep track of all the -proofs on both chains in a secure manner, for the normal work-flow, we -can run a relay node that handles the cross-chain interaction. - -In this case, there are only two steps. First ``basecoin relay init``, -which must be run once to register each chain with the other one, and -make sure they are ready to send and recieve.

-The SDK design optimizes flexibility and security.

In addition, -all modules are sandboxed for greater application security. - -Framework Overview ------------------- - -Object-Capability Model -~~~~~~~~~~~~~~~~~~~~~~~ - -When thinking about security, it's good to start with a specific threat model. Our threat model is the following: - -:: - - We assume that a thriving ecosystem of Cosmos-SDK modules that are easy to compose into a blockchain application will contain faulty or malicious modules. - -The Cosmos-SDK is designed to address this threat by being the foundation of an object capability system. - -:: - - The structural properties of object capability systems favor - modularity in code design and ensure reliable encapsulation in - code implementation. - - These structural properties facilitate the analysis of some - security properties of an object-capability program or operating - system. Some of these — in particular, information flow properties - — can be analyzed at the level of object references and - connectivity, independent of any knowledge or analysis of the code - that determines the behavior of the objects. As a consequence, - these security properties can be established and maintained in the - presence of new objects that contain unknown and possibly - malicious code. - - These structural properties stem from the two rules governing - access to existing objects: - - 1) An object A can send a message to B only if object A holds a - reference to B. - - 2) An object A can obtain a reference to C only - if object A receives a message containing a reference to C. As a - consequence of these two rules, an object can obtain a reference - to another object only through a preexisting chain of references. - In short, "Only connectivity begets connectivity." - -See the `wikipedia article `__ for more information. - -Strictly speaking, Golang does not implement object capabilities completely, because of several issues: - -* pervasive ability to import primitive modules (e.g. "unsafe", "os") -* pervasive ability to override module vars https://github.com/golang/go/issues/23161 -* data-race vulnerability where 2+ goroutines can create illegal interface values - -The first is easy to catch by auditing imports and using a proper dependency version control system like Dep. The second and third are unfortunate but it can be audited with some cost. - -Perhaps `Go2 will implement the object capability model `__. - -What does it look like? -^^^^^^^^^^^^^^^^^^^^^^^ - -Only reveal what is necessary to get the work done. - -For example, the following code snippet violates the object capabilities principle: - -:: - - type AppAccount struct {...} - var account := &AppAccount{ - Address: pub.Address(), - Coins: sdk.Coins{{"ATM", 100}}, - } - var sumValue := externalModule.ComputeSumValue(account) - -The method "ComputeSumValue" implies a pure function, yet the implied capability of accepting a pointer value is the capability to modify that value. The preferred method signature should take a copy instead. - -:: - - var sumValue := externalModule.ComputeSumValue(*account) - -In the Cosmos SDK, you can see the application of this principle in the basecoin examples folder. - -:: - - // File: cosmos-sdk/examples/basecoin/app/init_handlers.go - package app - - import ( - "github.com/cosmos/cosmos-sdk/x/bank" - "github.com/cosmos/cosmos-sdk/x/sketchy" - ) - - func (app *BasecoinApp) initRouterHandlers() { - - // All handlers must be added here. - // The order matters. - app.router.AddRoute("bank", bank.NewHandler(app.accountMapper)) - app.router.AddRoute("sketchy", sketchy.NewHandler()) - } - -In the Basecoin example, the sketchy handler isn't provided an account mapper, which does provide the bank handler with the capability (in conjunction with the context of a transaction run). - -Security Overview ------------------ - -For examples, see the `examples `__ directory. - -Design Goals -~~~~~~~~~~~~ - -The design of the Cosmos SDK is based on the principles of "capabilities systems". - -Capabilities systems -~~~~~~~~~~~~~~~~~~~~ - -TODO: - -* Need for module isolation -* Capability is implied permission -* Link to thesis - -Tx & Msg -~~~~~~~~ - -The SDK distinguishes between transactions (Tx) and messages -(Msg). A Tx is a Msg wrapped with authentication and fee data. - -Messages -^^^^^^^^ - -Users can create messages containing arbitrary information by -implementing the ``Msg`` interface: - -:: - - type Msg interface { - - // Return the message type. - // Must be alphanumeric or empty. - Type() string - - // Get the canonical byte representation of the Msg. - GetSignBytes() []byte - - // ValidateBasic does a simple validation check that - // doesn't require access to any other information. - ValidateBasic() error - - // Signers returns the addrs of signers that must sign. - // CONTRACT: All signatures must be present to be valid. - // CONTRACT: Returns addrs in some deterministic order. - GetSigners() []Address - } - -Messages must specify their type via the ``Type()`` method. The type should -correspond to the messages handler, so there can be many messages with the same -type. - -Messages must also specify how they are to be authenticated. The ``GetSigners()`` -method return a list of addresses that must sign the message, while the -``GetSignBytes()`` method returns the bytes that must be signed for a signature -to be valid. - -Addresses in the SDK are arbitrary byte arrays that are hex-encoded when -displayed as a string or rendered in JSON. - -Messages can specify basic self-consistency checks using the ``ValidateBasic()`` -method to enforce that message contents are well formed before any actual logic -begins. - -For instance, the ``Basecoin`` message types are defined in ``x/bank/tx.go``: - -:: - - type SendMsg struct { - Inputs []Input `json:"inputs"` - Outputs []Output `json:"outputs"` - } - - type IssueMsg struct { - Banker sdk.Address `json:"banker"` - Outputs []Output `json:"outputs"` - } - -Each specifies the addresses that must sign the message: - -:: - - func (msg SendMsg) GetSigners() []sdk.Address { - addrs := make([]sdk.Address, len(msg.Inputs)) - for i, in := range msg.Inputs { - addrs[i] = in.Address - } - return addrs - } - - func (msg IssueMsg) GetSigners() []sdk.Address { - return []sdk.Address{msg.Banker} - } - -Transactions -^^^^^^^^^^^^ - -A transaction is a message with additional information for authentication: - -:: - - type Tx interface { - - GetMsg() Msg - - // Signatures returns the signature of signers who signed the Msg. - // CONTRACT: Length returned is same as length of - // pubkeys returned from MsgKeySigners, and the order - // matches. - // CONTRACT: If the signature is missing (ie the Msg is - // invalid), then the corresponding signature is - // .Empty(). - GetSignatures() []StdSignature - } - -The ``tx.GetSignatures()`` method returns a list of signatures, which must match -the list of addresses returned by ``tx.Msg.GetSigners()``. The signatures come in -a standard form: - -:: - - type StdSignature struct { - crypto.PubKey // optional - crypto.Signature - AccountNumber int64 - Sequence int64 - } - -It contains the signature itself, as well as the corresponding account's account and -sequence numbers. The sequence number is expected to increment every time a -message is signed by a given account. The account number stays the same and is assigned -when the account is first generated. These prevent "replay attacks", where -the same message could be executed over and over again. - -The ``StdSignature`` can also optionally include the public key for verifying the -signature. An application can store the public key for each address it knows -about, making it optional to include the public key in the transaction. In the -case of Basecoin, the public key only needs to be included in the first -transaction send by a given account - after that, the public key is forever -stored by the application and can be left out of transactions. - -The standard way to create a transaction from a message is to use the ``StdTx``: - -:: - - type StdTx struct { - Msg - Signatures []StdSignature - } - -Encoding and Decoding Transactions -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Messages and transactions are designed to be generic enough for developers to -specify their own encoding schemes. This enables the SDK to be used as the -framwork for constructing already specified cryptocurrency state machines, for -instance Ethereum. - -When initializing an application, a developer must specify a ``TxDecoder`` -function which determines how an arbitrary byte array should be unmarshalled -into a ``Tx``: - -:: - - type TxDecoder func(txBytes []byte) (Tx, error) - -In ``Basecoin``, we use the Tendermint wire format and the ``go-amino`` library for -encoding and decoding all message types. The ``go-amino`` library has the nice -property that it can unmarshal into interface types, but it requires the -relevant types to be registered ahead of type. Registration happens on a -``Codec`` object, so as not to taint the global name space. - -For instance, in ``Basecoin``, we wish to register the ``SendMsg`` and ``IssueMsg`` -types: - -:: - - cdc.RegisterInterface((*sdk.Msg)(nil), nil) - cdc.RegisterConcrete(bank.SendMsg{}, "cosmos-sdk/SendMsg", nil) - cdc.RegisterConcrete(bank.IssueMsg{}, "cosmos-sdk/IssueMsg", nil) - -Note how each concrete type is given a name - these name determine the type's -unique "prefix bytes" during encoding. A registered type will always use the -same prefix-bytes, regardless of what interface it is satisfying. For more -details, see the `go-amino documentation `__. - - -MultiStore -~~~~~~~~~~ - -MultiStore is like a filesystem -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - -Mounting an IAVLStore -^^^^^^^^^^^^^^^^^^^^^ - -TODO: - -* IAVLStore: Fast balanced dynamic Merkle store. - - * supports iteration. - -* MultiStore: multiple Merkle tree backends in a single store - - * allows using Ethereum Patricia Trie and Tendermint IAVL in same app - -* Provide caching for intermediate state during execution of blocks and transactions (including for iteration) -* Historical state pruning and snapshotting. -* Query proofs (existence, absence, range, etc.) on current and retained historical state. - -Context -------- - -The SDK uses a ``Context`` to propogate common information across functions. The -``Context`` is modelled after the Golang ``context.Context`` object, which has -become ubiquitous in networking middleware and routing applications as a means -to easily propogate request context through handler functions. - -The main information stored in the ``Context`` includes the application -MultiStore (see below), the last block header, and the transaction bytes. -Effectively, the context contains all data that may be necessary for processing -a transaction. - -Many methods on SDK objects receive a context as the first argument. - -Handler -------- - -Transaction processing in the SDK is defined through ``Handler`` functions: - -:: - - type Handler func(ctx Context, tx Tx) Result - -A handler takes a context and a transaction and returns a result. All -information necessary for processing a transaction should be available in the -context. - -While the context holds the entire application state (all referenced from the -root MultiStore), a particular handler only needs a particular kind of access -to a particular store (or two or more). Access to stores is managed using -capabilities keys and mappers. When a handler is initialized, it is passed a -key or mapper that gives it access to the relevant stores. - -:: - - // File: cosmos-sdk/examples/basecoin/app/init_stores.go - app.BaseApp.MountStore(app.capKeyMainStore, sdk.StoreTypeIAVL) - app.accountMapper = auth.NewAccountMapper( - app.capKeyMainStore, // target store - &types.AppAccount{}, // prototype - ) - - // File: cosmos-sdk/examples/basecoin/app/init_handlers.go - app.router.AddRoute("bank", bank.NewHandler(app.accountMapper)) - - // File: cosmos-sdk/x/bank/handler.go - // NOTE: Technically, NewHandler only needs a CoinMapper - func NewHandler(am sdk.AccountMapper) sdk.Handler { - return func(ctx sdk.Context, msg sdk.Msg) sdk.Result { - cm := CoinMapper{am} - ... - } - } - -AnteHandler ------------ - -Handling Fee payment -~~~~~~~~~~~~~~~~~~~~ - -Handling Authentication -~~~~~~~~~~~~~~~~~~~~~~~ - -Accounts and x/auth -------------------- - -sdk.Account -~~~~~~~~~~~ - -auth.BaseAccount -~~~~~~~~~~~~~~~~ - -auth.AccountMapper -~~~~~~~~~~~~~~~~~~ - -Wire codec ----------- - -Why another codec? -~~~~~~~~~~~~~~~~~~ - -vs encoding/json -~~~~~~~~~~~~~~~~ - -vs protobuf -~~~~~~~~~~~ - -KVStore example ---------------- - -Basecoin example ----------------- - -The quintessential SDK application is Basecoin - a simple -multi-asset cryptocurrency. Basecoin consists of a set of -accounts stored in a Merkle tree, where each account may have -many coins. There are two message types: SendMsg and IssueMsg. -SendMsg allows coins to be sent around, while IssueMsg allows a -set of predefined users to issue new coins. diff --git

20% of global stake - - The most recent week if they have = 0% of global stake - - Linear interpolation of the above two scenarios - -Liveliness kicks are only checked when a `TxLivelinessCheck` transaction is -submitted. - -``` golang -type TxLivelinessCheck struct { - PubKey crypto.PubKey - RewardAccount Addresss -} -``` - -If the `TxLivelinessCheck is successful in kicking a validator, 5% of the -liveliness punishment is provided as a reward to `RewardAccount`. - -#### Validator Liveliness Proof - -If the validator was kicked for liveliness issues and is able to regain -liveliness then all delegators in the temporary unbonding pool which have not -transacted to move will be bonded back to the now-live validator and begin to -once again collect provisions and rewards. Regaining livliness is demonstrated -by sending in a `TxProveLive` transaction: - -``` golang -type TxProveLive struct { - PubKey crypto.PubKey -} -``` - -## Delegator bond - -Atom holders may delegate coins to validators, under this circumstance their -funds are held in a `DelegatorBond`. It is owned by one delegator, and is -associated with the shares for one validator. The sender of the transaction is -considered to be the owner of the bond, - -``` golang -type DelegatorBond struct { - Candidate crypto.PubKey - Shares rational.Rat - AdjustmentFeePool coin.Coins - AdjustmentRewardPool coin.Coins -} -``` - -Description: - - Candidate: pubkey of the validator candidate: bonding too - - Shares: the number of shares received from the validator candidate - - AdjustmentFeePool: Adjustment factor used to passively calculate each bonds - entitled fees from `GlobalState.FeePool` - - AdjustmentRewardPool: Adjustment factor used to passively calculate each - bonds entitled fees from `Candidate.ProposerRewardPool`` - -Each `DelegatorBond` is individually indexed within the store by delegator -address and candidate pubkey. - - - key: Delegator and Candidate-Pubkey - - value: DelegatorBond - - -### Delegating - -Delegator bonds are created using the TxDelegate transaction. Within this -transaction the validator candidate queried with an amount of coins, whereby -given the current exchange rate of candidate's delegator-shares-to-atoms the -candidate will return shares which are assigned in `DelegatorBond.Shares`. - -``` golang -type TxDelegate struct { - PubKey crypto.PubKey - Amount coin.Coin -} -``` - -### Unbonding - -Delegator unbonding is defined by the following transaction type: - -``` golang -type TxUnbond struct { - PubKey crypto.PubKey - Shares rational.Rat -} -``` - -When unbonding is initiated, delegator shares are immediately removed from the -candidate and added to a queue object. - -``` golang -type QueueElemUnbondDelegation struct { - QueueElem - Payout Address // account to pay out to - Shares rational.Rat // amount of shares which are unbonding - StartSlashRatio rational.Rat // candidate slash ratio at start of re-delegation -} -``` - -In the unbonding queue - the fraction of all historical slashings on -that validator are recorded (`StartSlashRatio`).

Similarly if the validator changes the commission -rate, all commission on fees must be simultaneously withdrawn. - -### Other general notes on fees accounting - -- When a delegator chooses to re-delegate shares, fees continue to accumulate - until the re-delegation queue reaches maturity. At the block which the queue - reaches maturity and shares are re-delegated all available fees are - simultaneously withdrawn. -- Whenever a totally new validator is added to the validator set, the `accum` - of the entire candidate must be 0, meaning that the initial value for - `candidate.Adjustment` must be set to the value of `canidate.Count` for the - height which the candidate is added on the validator set. -- The feePool of a new delegator bond will be 0 for the height at which the bond - was added. This is achieved by setting `DelegatorBond.FeeWithdrawalHeight` to - the height which the bond was added. diff --git a/docs/spec/staking/overview.md b/docs/spec/staking/overview.md deleted file mode 100644 index a202fbc1192c..000000000000 --- a/docs/spec/staking/overview.md +++ /dev/null @@ -1,214 +0,0 @@ -# Staking Module - -## Overview - -The Cosmos Hub is a Tendermint-based Proof of Stake blockchain system that -serves as a backbone of the Cosmos ecosystem. It is operated and secured by an -open and globally decentralized set of validators. Tendermint consensus is a -Byzantine fault-tolerant distributed protocol that involves all validators in -the process of exchanging protocol messages in the production of each block. To -avoid Nothing-at-Stake problem, a validator in Tendermint needs to lock up -coins in a bond deposit. Tendermint protocol messages are signed by the -validator's private key, and this is a basis for Tendermint strict -accountability that allows punishing misbehaving validators by slashing -(burning) their bonded Atoms. On the other hand, validators are rewarded for -their service of securing blockchain network by the inflationary provisions and -transactions fees. This incentives correct behavior of the validators and -provides the economic security of the network. - -The native token of the Cosmos Hub is called Atom; becoming a validator of the -Cosmos Hub requires holding Atoms. However, not all Atom holders are validators -of the Cosmos Hub. More precisely, there is a selection process that determines -the validator set as a subset of all validator candidates (Atom holders that -wants to become a validator). The other option for Atom holder is to delegate -their atoms to validators, i.e., being a delegator. A delegator is an Atom -holder that has bonded its Atoms by delegating it to a validator (or validator -candidate). By bonding Atoms to secure the network (and taking a risk of being -slashed in case of misbehaviour), a user is rewarded with inflationary -provisions and transaction fees proportional to the amount of its bonded Atoms. -The Cosmos Hub is designed to efficiently facilitate a small numbers of -validators (hundreds), and large numbers of delegators (tens of thousands). -More precisely, it is the role of the Staking module of the Cosmos Hub to -support various staking functionality including validator set selection, -delegating, bonding and withdrawing Atoms, and the distribution of inflationary -provisions and transaction fees. - -## Basic Terms and Definitions - -* Cosmsos Hub - a Tendermint-based Proof of Stake blockchain system -* Atom - native token of the Cosmsos Hub -* Atom holder - an entity that holds some amount of Atoms -* Candidate - an Atom holder that is actively involved in the Tendermint - blockchain protocol (running Tendermint Full Node (TODO: add link to Full - Node definition) and is competing with other candidates to be elected as a - validator (TODO: add link to Validator definition)) -* Validator - a candidate that is currently selected among a set of candidates - to be able to sign protocol messages in the Tendermint consensus protocol -* Delegator - an Atom holder that has bonded some of its Atoms by delegating - them to a validator (or a candidate) -* Bonding Atoms - a process of locking Atoms in a bond deposit (putting Atoms - under protocol control). Atoms are always bonded through a validator (or - candidate) process. Bonded atoms can be slashed (burned) in case a validator - process misbehaves (does not behave according to the protocol specification). - Atom holders can regain access to their bonded Atoms if they have not been - slashed by waiting an Unbonding period. -* Unbonding period - a period of time after which Atom holder gains access to - its bonded Atoms (they can be withdrawn to a user account) or they can be - re-delegated. -* Inflationary provisions - inflation is the process of increasing the Atom supply. - Atoms are periodically created on the Cosmos Hub and issued to bonded Atom holders. - The goal of inflation is to incentize most of the Atoms in existence to be bonded. -* Transaction fees - transaction fee is a fee that is included in a Cosmsos Hub - transaction. The fees are collected by the current validator set and - distributed among validators and delegators in proportion to their bonded - Atom share. -* Commission fee - a fee taken from the transaction fees by a validator for - their service - -## The pool and the share - -At the core of the Staking module is the concept of a pool which denotes a -collection of Atoms contributed by different Atom holders. There are two global -pools in the Staking module: the bonded pool and unbonding pool. Bonded Atoms -are part of the global bonded pool. If a candidate or delegator wants to unbond -its Atoms, those Atoms are moved to the the unbonding pool for the duration of -the unbonding period. In the Staking module, a pool is a logical concept, i.e., -there is no pool data structure that would be responsible for managing pool -resources. Instead, it is managed in a distributed way. More precisely, at the -global level, for each pool, we track only the total amount of bonded or unbonded -Atoms and the current amount of issued shares. A share is a unit of Atom distribution -and the value of the share (share-to-atom exchange rate) changes during -system execution. The share-to-atom exchange rate can be computed as: - -`share-to-atom-exchange-rate = size of the pool / ammount of issued shares` - -Then for each validator candidate (in a per candidate data structure) we keep track of -the amount of shares the candidate owns in a pool. At any point in time, -the exact amount of Atoms a candidate has in the pool can be computed as the -number of shares it owns multiplied with the current share-to-atom exchange rate: - -`candidate-coins = candidate.Shares * share-to-atom-exchange-rate` - -The benefit of such accounting of the pool resources is the fact that a -modification to the pool from bonding/unbonding/slashing/provisioning of -Atoms affects only global data (size of the pool and the number of shares) and -not the related validator/candidate data structure, i.e., the data structure of -other validators do not need to be modified. This has the advantage that -modifying global data is much cheaper computationally than modifying data of -every validator. Let's explain this further with several small examples: - -We consider initially 4 validators p1, p2, p3 and p4, and that each validator -has bonded 10 Atoms to the bonded pool. Furthermore, let's assume that we have -issued initially 40 shares (note that the initial distribution of the shares, -i.e., share-to-atom exchange rate can be set to any meaningful value), i.e., -share-to-atom-ex-rate = 1 atom per share. Then at the global pool level we -have, the size of the pool is 40 Atoms, and the amount of issued shares is -equal to 40. And for each validator we store in their corresponding data -structure that each has 10 shares of the bonded pool. Now lets assume that the -validator p4 starts process of unbonding of 5 shares. Then the total size of -the pool is decreased and now it will be 35 shares and the amount of Atoms is -35 . Note that the only change in other data structures needed is reducing the -number of shares for a validator p4 from 10 to 5. - -Let's consider now the case where a validator p1 wants to bond 15 more atoms to -the pool. Now the size of the pool is 50, and as the exchange rate hasn't -changed (1 share is still worth 1 Atom), we need to create more shares, i.e. we -now have 50 shares in the pool in total. Validators p2, p3 and p4 still have -(correspondingly) 10, 10 and 5 shares each worth of 1 atom per share, so we -don't need to modify anything in their corresponding data structures. But p1 -now has 25 shares, so we update the amount of shares owned by p1 in its -data structure. Note that apart from the size of the pool that is in Atoms, all -other data structures refer only to shares. - -Finally, let's consider what happens when new Atoms are created and added to -the pool due to inflation. Let's assume that the inflation rate is 10 percent -and that it is applied to the current state of the pool. This means that 5 -Atoms are created and added to the pool and that each validator now -proportionally increase it's Atom count. Let's analyse how this change is -reflected in the data structures. First, the size of the pool is increased and -is now 55 atoms. As a share of each validator in the pool hasn't changed, this -means that the total number of shares stay the same (50) and that the amount of -shares of each validator stays the same (correspondingly 25, 10, 10, 5). But -the exchange rate has changed and each share is now worth 55/50 Atoms per -share, so each validator has effectively increased amount of Atoms it has. So -validators now have (correspondingly) 55/2, 55/5, 55/5 and 55/10 Atoms. - -The concepts of the pool and its shares is at the core of the accounting in the -Staking module. It is used for managing the global pools (such as bonding and -unbonding pool), but also for distribution of Atoms between validator and its -delegators (we will explain this in section X). - -#### Delegator shares - -A candidate is, depending on it's status, contributing Atoms to either the -bonded or unbonding pool, and in return gets some amount of (global) pool -shares. Note that not all those Atoms (and respective shares) are owned by the -candidate as some Atoms could be delegated to a candidate. The mechanism for -distribution of Atoms (and shares) between a candidate and it's delegators is -based on a notion of delegator shares. More precisely, every candidate is -issuing (local) delegator shares (`Candidate.IssuedDelegatorShares`) that -represents some portion of global shares managed by the candidate -(`Candidate.GlobalStakeShares`). The principle behind managing delegator shares -is the same as described in [Section](#The pool and the share). We now -illustrate it with an example. - -Let's consider 4 validators p1, p2, p3 and p4, and assume that each validator -has bonded 10 Atoms to the bonded pool. Furthermore, let's assume that we have -issued initially 40 global shares, i.e., that -`share-to-atom-exchange-rate = 1 atom per share`. So we will set -`GlobalState.BondedPool = 40` and `GlobalState.BondedShares = 40` and in the -Candidate data structure of each validator `Candidate.GlobalStakeShares = 10`. -Furthermore, each validator issued 10 delegator shares which are initially -owned by itself, i.e., `Candidate.IssuedDelegatorShares = 10`, where -`delegator-share-to-global-share-ex-rate = 1 global share per delegator share`. -Now lets assume that a delegator d1 delegates 5 atoms to a validator p1 and -consider what are the updates we need to make to the data structures. First, -`GlobalState.BondedPool = 45` and `GlobalState.BondedShares = 45`. Then, for -validator p1 we have `Candidate.GlobalStakeShares = 15`, but we also need to -issue also additional delegator shares, i.e., -`Candidate.IssuedDelegatorShares = 15` as the delegator d1 now owns 5 delegator -shares of validator p1, where each delegator share is worth 1 global shares, -i.e, 1 Atom. Lets see now what happens after 5 new Atoms are created due to -inflation. In that case, we only need to update `GlobalState.BondedPool` which -is now equal to 50 Atoms as created Atoms are added to the bonded pool. Note -that the amount of global and delegator shares stay the same but they are now -worth more as share-to-atom-exchange-rate is now worth 50/45 Atoms per share. -Therefore, a delegator d1 now owns: - -`delegatorCoins = 5 (delegator shares) * 1 (delegator-share-to-global-share-ex-rate) * 50/45 (share-to-atom-ex-rate) = 5.55 Atoms` - -### Inflation provisions - -Validator provisions are minted on an hourly basis (the first block of a new -hour). The annual target of between 7% and 20%. The long-term target ratio of -bonded tokens to unbonded tokens is 67%. - -The target annual inflation rate is recalculated for each provisions cycle. The -inflation is also subject to a rate change (positive or negative) depending on -the distance from the desired ratio (67%). The maximum rate change possible is -defined to be 13% per year, however the annual inflation is capped as between -7% and 20%. - -```go -inflationRateChange(0) = 0 -GlobalState.Inflation(0) = 0.07 - -bondedRatio = GlobalState.BondedPool / GlobalState.TotalSupply -AnnualInflationRateChange = (1 - bondedRatio / 0.67) * 0.13 - -annualInflation += AnnualInflationRateChange - -if annualInflation > 0.20 then GlobalState.Inflation = 0.20 -if annualInflation < 0.07 then GlobalState.Inflation = 0.07 - -provisionTokensHourly = GlobalState.TotalSupply * GlobalState.Inflation / (365.25*24) -``` - -Because the validators hold a relative bonded share (`GlobalStakeShares`), when -more bonded tokens are added proportionally to all validators, the only term -which needs to be updated is the `GlobalState.BondedPool`.
