Problem Definition

app/app.go is too big file.

provenance/app

Hi there! I really liked your PR for the hub, this one:

• app.go cleanup cosmos/gaia#1580

I have been in seoul and unable to give it a proper review.

Are the osmo and provenance styles different?

Point blank: I agree with you.

@faddat - refactor useful? might be some good practice to get warm.

regarding the git workflow here - already made a decision on how to get started?
( the pull / branch strategy we should go for )

cosmos/gaia#1580 (review)

[Anmol1696]

@faddat provenance style is a little different in the sense they define there upgrades as a map with values as the upgrade function like this, then they have functions to deal with this map and create handlers out of this.

In osmo this is more modular and we create a package itself per upgrade version, instead of a key value in map.

I prefer the osmo way since it is cleaner and will be able to do alot more, includig handling forks better as well.

PS. Would like to contribute to this, once we agree on the approach, i dont mind raising a PR and then have discussion then.

I'm very happy ot use the osmo style :D
