Agenda

  • Recent issues - help wanted 

  • Recently merged PRs and Status updates:

    • Multitenancy - @Ian Costanzo @Timo Glastra @Victor Martinez 

      • Ready and working with relay functionality - code routes the message to the relevant wallet, Alice/Faber Demo – see code for examples

        • Managed wallets – base wallet handles the keys of the sub-wallets

        • In progress: Unmanaged wallets – keys are elsewhere – e.g. in a custodial use case - thin wallet

      • Next: test, docs, demos and integrating with mediator support

    • Mediator - @Daniel Bluhm  @Adam Burdett

      • Coordinate mediation work

      • Integrated that with connections – enabled construction of the peer DID to use the mediator

      • In progress – Admin API for using the mediator/managing

      • Next: Docs, demos, DID Exchange support

  • ACA-Py AMA with the core maintainers

    • Custodial Wallets Use Case

      • Attack surfaces and GDPR compliance

      • Separation of keys and wallet/data

        • Unmanaged wallets are the multi-tenancy approach

        • Example – Biometric on the user side, keys on cloud HSM, separate from the wallets - need to figure out how/when to bring the data/keys together

          • Goal - pluggable method to get the key to the wallet.

  • Integration Testing - Timo

    • Unit tests are there, but that's not enough.  Though we have 99% coverage.

    • Idea is to add a Behave framework to ACA-Py to enable integration tests for feature (vs. interop testing).

      • Need to be conscious of Aries Agent Test Harness

  • Current active work:

    • Web hooks re-organization

    • Persistent queues

    • Indy / Aries Shared components

  • Other Discussion

Next Meeting

  • ACA-Py Roadmap – what's next?
