Welcome / Introductions

Announcements

...

  • Aries Protocol Test Suite
    • Issue, credential, and proof tests are merged.
  • Aries Shared:
    • indy-vdr (Andrew Whitehead) https://github.com/hyperledger/indy-vdr
      • Remaining work: Design doc, FFI, testing, CI / CD
      • As an Aries interface becomes standardized, will add that API layer
      • HTTP Proxy App updates
        • ACAPy using it as a proxy in a branch
      • Integrating into LibIndy in a separate branch, goal is to release in April/May
      • Rich Schemas functions are coming soon
      • Split out an Indy-Util to contain common components between Indy-VDR and Indy-Credx
        • Need to check that duplicate copies of the util library doesn't cause trouble.
      • GitHub actions runs unit tests and basic integration tests
      • VON Network browser moved to Indy-VDR instead of LibIndy (no wallet needed because it is stateless)
      • Andrew working a large refactor in a PR
      • Put rich shemas behind a feature flag?
    • indy-credx and aries-credx
      • https://github.com/sovrin-foundation/aries-credx-framework-rs
        • Generic APIs that are pluggable
        • Test vectors for interop
        • Coming soon: Rich Schemas functions
        • 6 most common attribute encodings
        • Does not yet have anoncreds 1 attribute encoding.
      • https://github.com/andrewwhitehead/indy-credx
        • Improved revocation (Annoncreds 1) support (faster tails generation)
        • Python wrapper using Pyo3 is solid. Needs FFI.
        • Can make a non-revocable credential and create proofs.
        • Tagging will be moved to the KMS.
        • Mike will be working on revocation registry 2.0
      • Integrating upgraded PyO3 library
      • Create an Indy-Util for API types and other utility functions?
    • Aries-Shared-Util
      • Pack / Unpack
      • Not started yet
    • Aries-KMS
      • Mike Lodder working Mike working on documentation and architecture as an Aries RFC (KMS architecture) and Ursa RFC (API)
        • Differs from Indy Wallet architecture by separating out auth and access control. Intention is to ensure a smooth transition from Indy.
        • Ability to export keys under certain conditions (metadata is set upon key creation)
        • PR is submitted: https://github.com/hyperledger/aries-rfcs/pull/440
      • Mike Mike and Cam's aries-core-rs → rs → aries-kms-mayaguez
        https://github.com/sovrin-foundation/aries-kms-rs
        • Evolution from lox
        • Persistence work allows plugging in any database engine.
        • Focus is using an external enclave.Will include a default storage that is not a different implementation from the plugins
      • Indy wallet crate might move to start another aries-kms implementation → aries-kms-vostok
    • Aries-Storage
      • Non-KMS entities
  • Aries-CloudAgent-Python (bc.gov)
    • Release 0.4.5 is on PyPi.
    • Revocation support has merged into master and is likely to included in the next release. Some smoothing of the edges happening.
      • Note: uses anoncreds 1.0 (hence, tails files) and so will be constrained in use cases to those with small numbers of credentials (e.g. ~25k per RevReg.)
  • Aries-Framework-Go (Troy) #aries-go
  • Aries-SDK-Ruby (Jack)
  • Aries-Framework-DotNet (Tomislav)
    • Release last week for Aries compatibility with ACApy and LibVCX (RFC 0094)
  • Aries-StaticAgent-Python
  • Aries-Toolbox
    • Added basic message admin
    • Working on a getting started video
  • Aries-SDK-Java
  • Aries-Framework-JavaScript / Aries-SDK-JavaScript
  • Rich Schemas and W3C Verifiable Credentials (Brent & Ken)
  • Aries-OSMA / Aries-MobileAgent-Xamarin
  • Ursa
    • 0.4.0 scheduled for late March
      • Hash Improved hash to curve algorithm
      • Updates to AMCL wrapper
    • To replace libsodium, need to have a replacement for the anoncrypt / authcrypt sealed box for pack / unpack.
      • Can be done in Ursa with two steps, but might add as a single function call.

RFC Progress

Other Business

...

  • We recognize as a community that each of us needs to adapt to current global events: improving the upstream open source libraries is likely to be slower.
    • No apology is needed if people take longer to respond to things.
    • My Richard's role changed, so we need a change in host.
    • Fewer meetings and more async collaboration?
