Merkle Tree Integration Benefits

Verifiable Key Directory
Provides a cryptographic proof that registered keys are properly stored and unmodified. By publishing only the Merkle root as a trust anchor, users can verify their registration status while maintaining the privacy of the full directory.

Permission Change Verification
Enables efficient verification of permission updates without requiring access to the complete permission set. Users can mathematically prove their current permissions are correctly reflected in the system while preserving the privacy of other users' permission relationships.

Auditable Operation Log
Creates an append-only, cryptographically verifiable log of all operations including key registrations and permission changes. Similar to Certificate Transparency logs, this provides transparency and accountability while maintaining user privacy and enabling efficient proofs of inclusion.

These features would enhance trust in the system by adding cryptographic verification capabilities without compromising the existing privacy model.

I’ve been kicking ideas like this around as well. https://github.com/transparency-dev/trillian-tessera looks pretty easy to integrate.
