    • Indy VDR into LibIndy
    • Indy Credx into LibIndy
• Aries Shared Libraries
  • Aries Shared:
    • indy-vdr (Andrew Whitehead)  https://github.com/hyperledger/indy-vdr
      • Nearing release 0.6(?) - most work complete that was needed: Design doc, FFI, testing, CI / CD
        • CI - GitHub actions runs unit tests and basic integration tests
        • CD not there
        • No design doc, but crate docs
        • Rich Schema merged and behind a feature flag
        • Refactoring PR not merged - cleanup, internal simplification, crate docs
      • As an Aries interface becomes standardized, will add that API layer
      • VON Network browser moved to Indy-VDR - branch
      • BC Gov created a tails server based on Indy-VDR - with dynamic ledger access
    • indy-credx - https://github.com/andrewwhitehead/indy-credx
      • need to move ASAP to at least BC Gov repo - Andrew Whitehead
      • ACA-Py branch created that can do credential exchange with indy-credx
      • Next up: adding revocation 2.0 support
      • Integrating upgraded PyO3 library
    • indy-shared-rs - https://github.com/bcgov/indy-shared-rs
      • Shared features across indy-vdr and indy-credx
      • pack/unpack on Ursa (not libsodium)
      • home for revocation support?  Or at least shared set membership proof handling?
      • Move to Hyperledger move this week...
    • aries-credx
      • https://github.com/sovrin-foundation/aries-credx-framework-rs
        • 6 most common attribute encodings
        • Does not have anoncreds 1 attribute encoding.
      • Can make a non-revocable credential and create proofs.
        • Tagging will be moved to the KMS.
        • Mike will be working on revocation registry 2.0
    • Aries Secure Storage initiatives:
      • Mike working on documentation and architecture as an Aries RFC (KMS architecture) and Ursa RFC (API)
        • PR is submitted: https://github.com/hyperledger/aries-rfcs/pull/440
      • Mike and Cam's work aries-kms-mayaguez - repo?  features?Postgres backend for credential storage
        https://github.com/sovrin-foundation/aries-kms-rs
        • Persistence work allows plugging in any database engine.
        • Focus is using an external enclave.
        • Working on Postgres storage; will need help on lox
        • Something out the end of the week.
  • Ursa
    • BBS+ added
    • 0.3.5 pending, plus new additions
