Agenda

• Update on BC Gov Code With Us – ACA-Py Indy-SDK to Askar conversion script - Indicio
  • Started from Andrew's script, SQLite only though
  • Adding Postgres support
  • Upgraded the per database wallet and adding tests
  • Repo is: https://github.com/Indicio-tech/acapy-wallet-upgrade; open question as to where it will live in the end – ACA-Py or external?  Leaning to leaving it outside.
  • Current branch: https://github.com/Indicio-tech/acapy-wallet-upgrade/tree/feature/psql-support
  • From Timo Glastra – AFJ issue: https://github.com/Indicio-tech/acapy-wallet-upgrade/tree/feature/psql-support
• Ledger-Agnostic AnonCreds Interface is ACA-Py: progress
  • Issue: #2044 in ACA-Py is about the ledger-agnostic AnonCreds interface
  • Hack MD Document: https://hackmd.io/Ailjb-WDTeC48EjF0gjrGA
    • DID Registration interface from DIF: https://identity.foundation/did-registration/ – basis of the API
    • Bottom line – a new endpoint /anoncreds will be added to the Admin API for handling AnonCreds
      • Will handle the differences in the ledgers
      • Tricky will be handling endorsing within Indy – and possibly other ledgers that need similar (but not the same) support
  • RootsID working on Cardano AnonCreds implementation
    • https://github.com/roots-id/cardano-anoncreds
    • AnonCreds Method Registry entry: https://hyperledger.github.io/anoncreds-methods-registry/#cardano-anoncreds-method 
  • Question from Alex in chat:  What would be the process to add cheqd and cardano anoncreds in acapy 1.0? Is the driver to write to the ledger enough?
    • From Timo Glastra : Alex, there's some work that needs to be done on the did registrar module, as you need to have the key in the wallet to publish to the ledgers
• BC Gov ACA-Py 1.0 Priorities – Project
  • Adding a Documentation site for ACA-Py - as nice as the AFJ one - https://aries.js.org/
  • AIP 2.0 Support
    • Legacy Peer DIDs / Peer DIDs / DID Key / Encryption Envelope
    • Please Ack
  • Other activities:
    • Cluster Support - PQs and Shared Cache - Documentation and Testing
    • OCA for Aries – Issuer support, plus holder for testing
    • Ledger Agnostic DIDs
    • Ledger Agnostic AnonCreds
      • Drop indy-sdk support in 1.0?
        • OK if we have the upgrade script and do some patch releases if really needed.
        • Agents with different underlying features can interop – indy-sdk and shared-components
  • Need a release roadmap, as that is a long list for 1.0.0.
• Open Discussion
  • Encryption Envelope for DIDComm V2, issues to discuss: 
    • Encryption envelope in Askar - how do we proceed to get that created?
    • Other libraries are available (Python, Rust, others) - e.g., SICPA – should we use one of those are keep working on Askar's implementation?
      • Askar – somethings are still missing
      • SICPA Python library is more complete - suggestion is to use that - donated to the OWF - contact SICPA to find out development status
        • Indicio also looking at it.
        • Use authlib – private keys are being called to a library – makes it harder to use an HSM for handling secrets
      • 2 or 3 others available - Rust, Go
      • Decision: Go with SICPA library for now.
  • Python upgrade
    • Completing the upgrade away from 3.6.  What is needed?
      • Creating images for 3.9 as the target - Daniel Bluhm has started, but if others want to pick it up, he'll review.
    • Why are 3.7 and 3.10 failing?  Could be a dependency issue away from 3.6.
    • First important step is 3.9 images.

Next Meeting

• Does anyone use/see a use case for Web Sockets and Return Route beyond ACA-Py as a mobile agent mediator?
• Issue 2029: Additional security controls for webhooks for multi-tenancy
