- 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
- PR with a starting point for discussing the design: https://github.com/hyperledger/anoncreds-rs/pull/266

- No
- Identifier within the
CredentialSubject
?- No
- Nested JSON and Arrays in AnonCreds credentials.
- Not supported
- Encoding scheme – move into AnonCreds or leave for the issuer?
- Leave
- Time of Day for the `IssuanceDate` field - random? Zeroed?
- 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?
- TBD – start simple
- "mapping" of source VC attributes/predicates to the presentation request.
- Using other than the AnonCreds presentation request model
- No
- Support Out of scope – support in the AnonCreds library for signing W3C VC/VP Format Data Integrity Proofs with other Proof Types.
- No
- There might be some "devil in the details" in this. Do we have to add extra values (notably

) to have a second signature?
- Altering the format/Data Model of the Credential Offer and Request format.
- No
- Proposed AnonCreds library API changes.
- For others to review
