      • Deprecate  additional wrappers (IS-1424) and LibVCX (IS-1416)
      • GitLab migration alongside Jenkins (Foundation)?
      • Warnings from rust cargo clippy (Mike and Axel), epic: IS-1401
  • Indy Catalyst
    • Production deployment testing: volume loads.
      • Happy with performance now.
    • Not yet migrated to Hyperledger. Needs more documentation.
  • New design for revocation / Anoncreds 2.0 (Mike)
    • Would be useful to have a comparison in performance between Anoncreds 1.0 and Anoncreds 2.0
    • Need a plan for changes to Indy Node
      • HIPE for overall changes, then a design PR for the changes specific to the different repos.
        https://github.com/hyperledger/indy-node/tree/master/design
      • BC.gov will implement the existing revocation capability in ACA-Py for use in constrained cases
        • Looking to build against Anoncreds 2.0 as soon as it is available.
        • Unable to contribute to the Anoncreds 2.0 revocation capability at this time - no resources for that work.

Main Business

  • Changes to the Transaction Author Agreement
  • Migrating LibIndy to Aries
    • Indy Resolver becomes Indy-Aries-VDRI
      • Can wait to follow the DID-resolution spec, because the spec doesn't have enough detail today.
    • Indy Anoncreds becomes Indy-Aries-Anoncreds
      • We prefer keeping it as a separate repo in Indy until another ledger shows interest.
      • We considered Aries-Shared-Creds-Anoncreds, but it is likely that it is closely tied to Indy at least in the short term. The interface should live in Aries.
    • Indy Wallet becomes Aries-Shared-KMS
      • Includes plugin interface
      • Aries-Shared-KMS-PostgreSQL
      • Aries-Shared-KMS-SQLite
  • Evernym can assist with:
    • Consensus
    • Revocation
    • Rich Schemas
    • DID Doc
  • Other themes from the Aries Connect-a-thon
  • Requirements questions:
    • INDY-2305: Add IP address range for outbound TCP connections from validator nodes
      • Changes the way nodes are represented in the Pool Ledger
  • How soon should we deprecate the LibIndy .NET wrapper.

Future Calls

  • January 13: Indy performance analysis (BC.gov)
  • 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?
  • Non-secrets in the Indy Wallet
    • Cam is working on pluggable crypto. The wallet shouldn't decide what encryption you should be using.
    • Use cases where we would want to move keys between wallets
      • Moving the link secret / credential data from one device to another (synchronized storage).
      • Debug use cases
      • Richard's hit other uses cases that were better solved with DID Doc,  pre-signing, signing API.
    • Work-around with the web-crypto API
  • Migration of Indy-SDK to Aries-Core

Action items

  • HIPE #138, Issue #144 (Ken and Brent)
    • Create a PR for changing status to ACCEPTED
    • Check for an Aries RFC
  • PR to RFC #0019 to compare pack/upack to msgpack (Sergey)
  • Richard and Sergey will close old pull requests with a descriptive comment.
  • Mike wants to review the 61 cases of "unsafe" libindy calls and figure out if they are justified.
