Main Business

  • Connection Redirect
    • Evernym has something working in LibVCX, and needs to contribute an Aries RFC
    • Stephen, George, Sam, and Andrew are working on a similar Aries RFC
  • Indy-Credx
    • https://github.com/andrewwhitehead/indy-credx
    • Using Pyo3: Python extension written in Rust that wraps crate directly. Improves performance and security. Allows multiple threads.
      • Expect to add an FFI interface in the future
    • Can issue credentials, no support for proof requests or revocation yet
  • Indy-VDR
  • "State proof" validation bug reported through the HTTP Proxy: audit ledger proof
    • IS-1502 - Getting issue details... STATUS
  • Need to decide the future of CI / CD
    • Need CI / CD for indy-vdr immediately
      • Does the team at BC.gov have plans?
        • Indy-VDR has a docker that can be used for tests
        • Want to create a GitHub action
      • Where should it live?
        • Current Jenkins infrastructure is aging
        • Foundation's GitLab environment isn't functional
        • Hyperledger is using Azure Pipelines, but concerns about running an Indy Pool there
        • Evernym team's recent research:
          • IS-1497 - Getting issue details... STATUS  GitLab
          • IS-1496 - Getting issue details... STATUS GitHub Actions
          • IS-1504 - Getting issue details... STATUS Circle CI
          • IS-1503 - Getting issue details... STATUS Azure Pipelines
    • Ursa doesn't have any CI
    • Decided: Move forward with GitHub Actions
  • Rich Schemas:
    • Need to correct existing HIPEs
    • Need to evolve DIF DIDComm to support Rich Schemas
    • Implement first in Indy-VDR and Indy-Credx, then decide how to migrate there from LibIndy.
    • How will we mix old credential definitions with new credential definitions?
      • Only difference is the mapping object
      • Anoncreds 1.0 vs 2.0 might require more effort to remain compatible. Anoncreds 2.0 only support Rich Schemas (new credential definition object)?

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?
