Other Business

• Progress on Rich Schemas Schemas / W3C Verifiable Credentials Ken Ebert
  • Milestone 1: Issue a credential
  • Milestone 2: Verify using a presentation definition with ZKP signatureCollaboration session

  • Rich Schemas Roadmap:

    • HIPE / RFCs (50% done)
      • Update existing HIPEs (Alex)
      HIPEs for new objects:
      • • Issuance in DIDComm
        • Proof in DIDComm
        • Mapping (Alex)
        • Cred Def (Alex)
        • Presentation Def (Ken and Brent)
        • Presentation (Ken and Brent)
        • Verifiable Credential (Alex)
      • Update existing HIPEs/RFCs (Alex)
      • HIPEs/RFCs for new objects:
      • Indy Node implementation (95% done) (Alex)
      • Indy-vdr (Andrew N)
      • Prerequisite: CI / CD for indy-vdr, and integration into Indy SDK
      • aries-credx (Andrew N and Echo)
      • create_w3c_cred
      • sign_w3c_cred 
      • verify_w3c_cred
      • create_presentation
    •  Milestones
      1. Issue a credential
      2. Verify using a presentation definition with ZKP signature
    • Aries-Framework-Go already supports W3C VC's: JSON-LD and JWTs
    • Avoid the term "Rich Schema" in artifacts and code.
  • Merge indy-credx with aries-credx?
    • https://github.com/sovrin-foundation/aries-credx-framework-rs
      • Generic APIs that are pluggable
      • Test vectors for interop
        
        • W3C test suite doesn't have encodings / mappings in the data model
        • But should test against the W3C test suite for the shape of the data model

        • aries-framework-go W3C test suite CI: https://github.com/hyperledger/aries-framework-go/actions?query=workflow%3Atest-suite

    • https://github.com/andrewwhitehead/indy-credx
      • Anoncreds 1.0 won't have the W3C credential container
  • Indy VDR is moved to Hyperledger
    • https://github.com/hyperledger/indy-vdr
  • CI / CD Aries shared libraries
    • Prefer GitHub Actions.
      
      • Use GitHub Actions Runner for iOS and Android hosted by the Sovrin Foundation.
      • Can easily migrate to Azure Pipelines or Circle CI if needed.
    • Aries-Framework-Go is using both GitHub Actions and (to a limited extent) Azure Pipelines
      • Azure Pipelines supported deployments that GitHub Actions didn't (likely does now)
      • Azure Pipelines worked better for heavy tests:  more computationally intensive and parallel
    • We plan to reduce the number of architectures. Won't support old devices.
  • When building Aries Util (pack / unpack) will migrate from LibSodium to Ursa key exchange?
    • Probably, but need additional testing.
  • BC.gov is using Pyo3 as well as FFI in shared libraries
    • Python extension written in Rust that wraps crate directly. Improves performance and security. Allows multiple threads.
    Merge indy-credx with aries-credx? (Ken Ebert)
    • Take a different approach for FII? Raw pointers or buffer paradigm instead of serialized strings

    • https://github.com/andrewwhitehead/indy-credx/blob/master/wrappers/python/src/buffer.rs

  Future Topics

  • Next Meeting (March 11)
    • Aries KMS design Mike Lodder
      • Architecture RFC
      • 3rd party libraries we could leverage:
        • Google Tink as an encryption library used in the KMS for aries-framework-go
  • Other:
    
    • Formal verification (Sven Hammann)
    • Where should we document interoperability results (AIP 1.0)? A page in this wiki space?
    • Hubs vs Agents
      • https://www.hyperledger.org/blog/2019/07/23/rhythm-and-melody-how-hubs-and-agents-rock-together
    • Status and future of wallet query language
    • IOT best practices (Robert Mitwicki, Adam Burdett , Lohan Spies )
    • DID Resolution W3C and Sam's concerns: https://github.com/hyperledger/aries-rfcs/issues/130
    • Architecture of Aries Verifiable Credentials Proof Formats (Mike Lodder)
