+# Storage Provider Management
+
+## Abstract
+
+SPs play a different role from Greenfield validators, although the same organizations or individuals can run both SPs
+and validators if they follow all the rules and procedures to get elected.
+
+The SP module is responsible for managing and maintaining several storage providers in the BNB Greenfield Decentralize
+Storage.
+
+- Metadata: The basic information about the SP, including address, tokens, status, and so on.
+- Deposit: Each SP who wants to join the storage network should stake tokens to ensure that it can provide storage
+services normally
+- Slash: The data stored on the SP will be challenged from time to time. When a challenge is successful, the SP will be
+slashed, and deduct some tokens.
+- Reputation: We will introduce a reputation system to evaluate SP's service quality. Users can choose which SP to store
+data based on reputation score.
+- Exit: The storage provider has the right to out of the service and gets back the staked tokens. When the storage
+provider has insufficient staked tokens or the reputation score is too low, InscriptionChain will force the storage
+provider to exit the storage network.
+
+## Key Workflow
+
+### Join the network
+
+SPs have to register themselves first by depositing on the Greenfield blockchain as their "Service Stake". Greenfield
+validators will go through a dedicated governance procedure to vote for the SPs of their election. SPs are encouraged to
+advertise their information and prove to the community their capability, as SPs have to provide a professional storage
+system with high-quality SLA.
+
+It will takes several transactions to join the greenfield storage network for storage provider.
+
+1. The funding account of sp should grant the governance module account to deduct tokens for staking.
+2. The sp submit a `CreateStorageProvider` proposal to governance module 
+3. Deposit enough tokens for this proposal
+4. The validators should vote for this proposal. Pass or reject.
+5. When enough validators vote the proposal, then the storage provider will be auto created on chain.
+
+### Leave the network
+
+When the SPs join and leave the network, they have to follow a series of actions to ensure data redundancy for the
+users; otherwise, their "Service Stake" will be fined. This is achieved through the data availability challenge and
+validator governance votes.
+
+### Reputation
+
+We'll introduce a reputation system for storage provider to evaluate the quality of service of SP.
+
+## State
+
+### StorageProvider
+
+Storage Provider can be ont of several statuses:
+
+* `STATUS_IN_SERVICE`: The sp is in service. it can serve user's Create/Upload/Download request.
+* `STATUS_IN_JAILED`: The sp was been slashed many times, and its deposit tokens is insufficient.
+* `STATUS_GRACEFUL_EXITING`: The SP is exiting gracefully. All the object stored in it will be shifted to another sp.
+* `STATUS_OUT_OF_SERVICE`: The SP is out of service. it can be a short-lived service unavailable. Users are unable 
+  to store or get payload data on it.
+
+Storage providers metadata should be primarily stored and accessed by the `OperatorAddr`, an EIP712 account address 
+for the operator of the storage provider. Three additional indices are maintained per storage provider metadata in 
+order to fulfill required lookups for SealObject/Deposit/Slash/GetApproval.
+
+* StorageProvider: `0x21 | OperatorAddr -> ProtocolBuffer(StorageProvider)`
+* StorageProviderByFundingAddress: `0x22 | FundingAddress -> OperatorAddr` 
+* StorageProviderBySealAddress: `0x23 | SealAddress -> OperatorAddr`
+* StorageProviderByApprovalAddress: `0x24 | ApprovalAddress -> OperatorAddr`
+
+Each storage provider's state is stored in a `StorageProvider` struct.
+
+```protobuf
+message StorageProvider {
+  option (gogoproto.equal) = false;
+  option (gogoproto.goproto_stringer) = false;
+
+  // operator_address defines the address of the sp's operator; It also is the unqiue index key of sp.
+  string operator_address = 1 [(cosmos_proto.scalar) = "cosmos.AddressString"];
+  // fund_address is the account address of the storage provider for deposit, remuneration.
+  string funding_address = 2 [(cosmos_proto.scalar) = "cosmos.AddressString"];
+  // seal_address is the account address of the storage provider for sealObject
+  string seal_address = 3 [(cosmos_proto.scalar) = "cosmos.AddressString"];
+  // approval_address is the account address of the storage provider for ack CreateBuclet/Object.
+  string approval_address = 4 [(cosmos_proto.scalar) = "cosmos.AddressString"];
+  // total_deposit define the deposit token
+  string total_deposit = 5 [
+    (cosmos_proto.scalar) = "cosmos.Int",
+    (gogoproto.customtype) = "github.com/cosmos/cosmos-sdk/types.Int",
+    (gogoproto.nullable) = false
+  ];
+  // status is the status of sp, which can be (in_service/read_only_service/graceful_exiting/out_of_service)
+  Status status = 6;
+  // endpoint is the service address of the storage provider
+  string endpoint = 7;
+  // description defines the description terms for the validator.
+  Description description = 8 [(gogoproto.nullable) = false];
+}
+```
+
+### Params
+Params is a module-wide configuration structure that stores system parameters
+and defines overall functioning of the sp module.
+
+```protobuf
+// Params defines the parameters for the module.
+message Params {
+  option (gogoproto.equal) = true;
+  option (gogoproto.goproto_stringer) = false;
+
+  // deposit_denom defines the staking coin denomination.
+  string deposit_denom = 1;
+  // min_deposit_amount defines the minimum deposit amount for storage providers.
+  string min_deposit = 2 [
+    (cosmos_proto.scalar) = "cosmos.Int",
+    (gogoproto.customtype) = "github.com/cosmos/cosmos-sdk/types.Int",
+    (gogoproto.nullable) = false
+  ];
+}
+```
+
+### Deposit Pool
+
+Sp module use its module account to manage all the staking tokens which deposit by storage providers.
+
+## Message
+
+### MsgCreateStorageProvider
+
+A storage provider is created using the `MsgCreateProvider` messages.
+
+```protobuf
+message MsgCreateStorageProvider {
+  option (cosmos.msg.v1.signer) = "creator";
+
+  string creator = 1 [(cosmos_proto.scalar) = "cosmos.AddressString"];
+  Description description = 2 [(gogoproto.nullable) = false];
+  string sp_address = 3 [(cosmos_proto.scalar) = "cosmos.AddressString"];
+  string funding_address = 4 [(cosmos_proto.scalar) = "cosmos.AddressString"];
+  string seal_address = 5 [(cosmos_proto.scalar) = "cosmos.AddressString"];
+  string approval_address = 6 [(cosmos_proto.scalar) = "cosmos.AddressString"];
+  string endpoint = 7;
+  cosmos.base.v1beta1.Coin deposit = 8 [(gogoproto.nullable) = false];
+}
+```
+
+This message is expected to fail if:
+
+* another storage provider with this operator/seal/funding/approval address is already registered.
+* the initial deposit tokens are of a denom not specified as the deposit denom of sp module
+* the deposit tokens is insufficient
+
+### MsgEditStorageProvider
+
+The metadata of a storage provider can be edit using `MsgEditStorageProvider` messages.
+
+```protobuf
+// MsgEditStorageProvider defines a SDK message for editing an existing sp.
+message MsgEditStorageProvider {
+  option (cosmos.msg.v1.signer) = "sp_address";
+
+  string sp_address = 1 [(cosmos_proto.scalar) = "cosmos.AddressString"];
+  string endpoint = 2;
+  Description description = 3 [(gogoproto.nullable) = false];
+}
+```
+
+This message is expected to fail if:
+
+* the storage provider is not exist
+* the description fields are too large
+
+### MsgDeposit
+
+When the deposit tokens of a storage provider is insufficient, it can use `MsgDeposit` messages to resupply the 
+deposit tokens.
+
+```protobuf
+// MsgDeposit defines a SDK message for deposit token for sp.
+message MsgDeposit {
+  option (cosmos.msg.v1.signer) = "creator";
+
+  // creator is the msg signer, it should be sp address or sp's fund address
+  string creator = 1 [(cosmos_proto.scalar) = "cosmos.AddressString"];
+  // sp_address is the operator address of sp
+  string sp_address = 2 [(cosmos_proto.scalar) = "cosmos.AddressString"];
+  // deposit is a mount of token which used to deposit for SP
+  cosmos.base.v1beta1.Coin deposit = 3 [(gogoproto.nullable) = false];
+}
+```
+
+This message is expected to fail if:
+
+* the storage provider is not exist
+* the deposit tokens are of a denom not specified as the deposit denom of sp module

+# Storage MetaData Models
+
+## Abstract
+The basic data models for Greenfield storage are:
+
+- bucket
+- object
+- group
+- permission
+
+These metadata are stored as blockchain state into the persistent storage of the Greenfield blockchain.
+
+## Concepts
+
+### Bucket
+
+Bucket is the unit to group storage "objects". BucketName has to be globally unique. Every user account can create a
+bucket. The account will become the "owner" of the bucket.
+
+Each bucket should be associated with its own Primary SP, and the payment accounts for Read and Store. The owner's
+address will be the default payment account.
+
+### Object
+
+Object is the basic unit to store data on Greenfield. The metadata for the object will be stored on the Greenfield
+blockchain:
+
+- name and ID
+- owner
+- bucket that hosts it
+- size and timestamps
+- content type
+- checkSums for the storage pieces
+- storage status
+- associated SP information
+
+Object metadata is stored with the bucket name as the prefix of the key. It is possible to iterate through all
+objects under the same bucket, but it may be a heavy-lifting job for a large bucket with lots of objects.
+
+### Group
+
+A Group is a collection of accounts with the same permissions. The group name is not allowed to be duplicated under the
+same user. However, a group can not create or own any resource. A group can not be a member of another group either.
+
+A resource can only have a limited number of groups associated with it for permissions. This ensures that the on-chain
+permission check can be finished within a constant time.
+
+## State
+
+The storage module keeps state of the following primary objects:
+
+* BucketInfo 
+* ObjectInfo
+* GroupInfo
+
+These primary objects should be primarily stored and accessed by the `ID` which is a auto-incremented sequence. An 
+additional indices are maintained per primary objects in order to compatibility with the S3 object storage.
+
+* BucketInfo: `0x11 | hash(bucketName) -> BigEndian(bucketId)`
+* ObjectInfo: `0x12 | hash(bucketName)_hash(objectName) -> BigEndian(objectId)`
+* GroupInfo: `0x13 | OwnerAddr_hash(groupName) -> BigEndian(groupId)`
+
+* BucketInfoById: `0x21 | BigEndian(bucketId) -> ProtoBuf(BucketInfo)`
+* ObjectInfoById: `0x22 | BigEndian(objectId) -> ProtoBuf(ObjectInfo)`
+* GroupInfoById: `0x23 | BigEndian(groupId) -> ProtoBuf(GroupInfo)`

+}
+```
+
+* the max_segment_size/redundant_data_chunk_num/redundant_parity_chunk_num is for redundancy algorithm
+* the max_payload_size is a limit on the size of objects uploaded by users
