Other Business

• Progress on Rich Schemas Ken EbertSchemas / W3C Verifiable Credentials Ken Ebert
  • Collaboration session

  • Rich Schemas Roadmap:

    • HIPE / RFCs (50% done)
      • 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
  • Milestone 1: Issue a credential
  • Milestone 2:
    1. Issue a credential
    1. 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.
  Merge indy-credx with aries-credx? (Ken Ebert)
  • Allows multiple threads.
  • 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)
