We need to finalize a decision on Lock Commitment for the BPI State Object the Interop Worksteps are working on:

Suggestion:

Use Sparse Merkle Tree (SMT) since this allows proof-of-non-membership of the hash of the BPI State Object.

That then needs a separate Smart Contract to

store the Merkle Proof & verify it
verification function that proof is correct (proof has to be verified onchain only once, and then we just need a mapping that says that the proof for this commitment was verified
Store function only for owning BPI
Verification function open to public
