- PRs to Review
- Design and planning – AnonCreds v1.0 in the W3C Verifiable Credentials Data Model Standard format
- The BC Gov Code With Us on AnonCreds Rust – https://marketplace.digital.gov.bc.ca/opportunities/code-with-us/d81f1bb4-4abb-4a4c-8b19-92904e0bd6a6
- Initial PR with a starting point for discussing the design: https://github.com/DSRCorporationhyperledger/anoncreds-rs/tree/design/w3c-support/pull/266
- Questions Raised:
- JSON-LD processing on the contexts?
- Identifier within the
CredentialSubject
? - Nested JSON and Arrays in AnonCreds credentials.
- Encoding scheme – move into AnonCreds or leave for the issuer?
- Time of Day for the `IssuanceDate` field
- Use of the term "Data Integrity Proof" to differentiate AnonCreds and non-AnonCreds Data Integrity Proofs.
- Simple vs. complex/size efficient encoding of the proof data into a single "proof" JSON item?
- "mapping" of source VC attributes/predicates to the presentation request.
- Using other than the AnonCreds presentation request model
- Out of scope – support in the AnonCreds library for signing W3C VC/VP Format Data Integrity Proofs with other Proof Types.
- There might be some "devil in the details" in this. Do we have to add extra values (notably
issuer
) to have a second signature?
