## Description
Implements [ICS-23](https://github.com/cosmos/ibc/tree/master/spec/core/ics-023-vector-commitments) conformant proofs for the SMT-based KV store and defines the proof spec as part of [ADR-040](eb7d939f86/docs/architecture/adr-040-storage-and-smt-state-commitments.md).
Closes: https://github.com/vulcanize/cosmos-sdk/issues/8
