Agenda

• Release 1.3.1.rc1 out – feedback?

  • Should be ready to go soon – need to cherry picking of three PRs and the LTS GHA.

• Update: Concurrency Challenges in ACA-Py – Issue #3738

  • The issue that raised the concern was triggered by a change in the code when transitioning from the old endpoints to the new AnonCreds endpoints. In those updates, a concurrency problem prevention mechanism was dropped. Putting it back should resolve the issue – e.g. at 99.7% (give or take).

  • Should we still do the distributed lock?

• Latest updates on Kanon.

• Adding Indy’s “endorser” type mechanisms to did:webvh server.

  • Adding a policy controlled publication rules to did:webvh for DIDs and (at least) AnonCreds resources

    • Or more generally, attested resources.

  • Use the did:webvh witness capability.

  • Implementing the equivalent of acapy-endorser-service to enable managing rules for what will be endorsed, and getting the signatures.

• Potential RevReg handling optimizations – (discussed previously) progress being made.

  • Document, presentation and recording (starting at the 12:56 mark) made yesterday’s AnonCreds meeting

• VerId team is looking at using ZKP Smart Contract for revocation

  • Using a circuit by the issuer and then publishing a smart contract

  • Issuer generates the ZKP (heavier work)

  • Holder provides a pointer to the ZKP to the verifier

  • Verifier verifies the proof (lightweight)

• Other work – adding MetaData to the CredDef

  • Description, display data, logo, OCA, SVG files

• Open Discussion
