Feature Request

Context

The SDK recently added support to allow node operators to restore app state from a local snapshot (and additionally manipulate app snapshots). For a more thorough context, see section "Application-implemented local state sync" from ADR 104 in #801.

As part of this work, the bootstrap-state command in the SDK handles the bootstrapping of a fresh comet-based node.

Problem

This SDK bootstrap-state command comprises initializing the block store and state store, as well as light client verification. All of these steps rely on internal interfaces of CometBFT.

Proposal

Ideally, the SDK should be provided with a simpler and direct API from Comet that handles this bootstrapping functionality. We should add a public Go API method for this purpose.
