Release Status and Work Updates

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
  - 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
    - 6 most common attribute encodings
    - Does not yet have anoncreds 1 attribute encoding.
  - https://github.com/andrewwhitehead/indy-credx
    - Can make a non-revocable credential and create proofs.
    - Tagging will be moved to the KMS.

    - PR is submitted: https://github.com/hyperledger/aries-rfcs/pull/440
  - Mike and Cam's aries-core-rs → aries-kms-mayaguez
    https://github.com/sovrin-foundation/aries-kms-rs
    - Persistence work allows plugging in any database engine.
    - Focus is using an external enclave.
  - 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
- Implementing the Out-Of-Band protocol
- Implementing issue-credential and present-proof protocols
Aries-SDK-Ruby (Jack)

Ursa
- 0.4.0 scheduled for late March
  - 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

Future of this meeting

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.
- Richard's role changed, so we need a change in host.
- Fewer meetings and more async collaboration?
