      • 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
    • Plan is to moving to aries-verified-credential-registry
    • 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.
      • 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.
  • Aries Shared Libraries

Main Business

  • Kiva update:
    • test networks is running Indy Node 1.8
      • Seeing some compatibility issues
    • created 5 million test wallets with citizen data
  • Non-secrets in the Indy Wallet
    • Cam is working on pluggable crypto. The wallet shouldn't decide what encryption you should be using.
    • Best practices with Indy today
      • Indy wallet wasn't designed for general storage, but people are using it because there aren't alternatives.
    • Shared goals for Aries
      • Aries-KMS is key specific
        • link secret should be treated the same as a key
      • Separate storage for connections, credentials, and protocol state
      • Need an additional storage for larger items
  • Use cases where we would want to move keys between wallets
    • We receive requests for moving the link secret / credential data from one device to another (synchronized storage)
      • Concerns with private keys ever leaving the wallet. If it can be done for any use case, how can it be protected against malicious use cases?
      • But wallet portability requires migration: export from one wallet, and import into a different wallet
        • migration between vendors
        • some types of upgrades
      • Preferred approach is to create a protocol for migrating credentials between wallets: move data and rotate to new private keys.
        • How do we handle the link secret?
    • Related use cases
      • backup and restore: storage layer backup
      • Debug use cases: unencrypted wallet plugin?
      • Delegation and guardianship: DID Doc
      • Enterprise use case:  pre-signing, signing API for arbitrary data.
    • Work-around with the web-crypto API

Future Calls

  • Results from performance testing LibIndy (
  • 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
    • 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

  • 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.
