          • CD not there
          • No design doc, but crate docs
        • As an Aries interface becomes standardized, will add that API layer
          • Do we hold off on setting the version until this is in place.  Maybe 0.8
        • GitHub actions runs unit tests and basic integration tests
        • VON Network browser moved to Indy-VDR instead of LibIndy (no wallet needed because it is stateless)
          • Andrew working a refactor in a PR
      • indy-credx - https://github.com/andrewwhitehead/indy-credx
        • 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)

      • Aries Secure Storage initiatives:
    • Ursa
      • Not covered

Other Business

  • Move to GitHub Issues from JIRA for indy-sdk, indy-node, indy-plenum
    • Activate issues, update README to mention history
    • Plan - Lazy Migration: Migrate current, likely to happen JIRAs to Issues as needed
      • NOTE: about 200 open issues on indy-sdk with a guess of about 50% to be moved
        • Even more open issues on plenum and node
    • Action: Stephen to get Ry to activate Github issues; update READMEs to reflect change.
  • Migrate Jenkins to GitHub Actions (and perhaps Azure pipelines)
    • Plan started - Sovrin resource migration
    • Resources:  Wade Barnes (BC Gov), Thor Wolpert (BC Gov) for first step (Indy SDK/Linux)
  • Revocation 2.0
    • Presentation (summary of what was presented on the Aries WG Call)
      • General agreement on the approach.
      • Comments from discussion:
        • The limiting factor will be the calculations and space needed by the prover to create the merkle tree interior nodes
        • What are the space/time trade-offs between repeating calculations per proof vs. caching the calculated tree?
        • Action: need some experimenting with the approach - compression and space/time for tree calculations
    • Please provide feedback on the proposed design (see JIRA: Indy-2365)
    • Do we need to update/release indy-node if transactions are the same but data is new?
      • Yes, but not much.  Mainly to verify the content of the data before writing to the ledger.

Future Calls

Next call:

Future:

  • Requirements questions:
    • IS-1099: anoncreds.prover_get_credentials_for_proof_req should return per-credential timestamp
      • Should we allow duplicate credentials from the same issuer?

Action items

  • PR to RFC #0019 to compare pack/upack to msgpack (Sergey)
  • Review the 61 cases of "unsafe" libindy calls and figure out if they are justified.
