AnonCreds RS

  • It appears there is enough typescript support in AnonCreds-RS for us to do the smallest demo w/AnonCreds-Cardano driver.

AnonCreds v2

  • Mike Lodder wanted to know if there should be a new meeting to begin work towards a v2 that includes his updates.

January 20, 2023 Working Group Meeting

Participants:

  • Lance Byrd (RootsID)
  • Ed Eykholt (BlockTrust)

Cardano AnonCreds Method

  • What dependencies does the typescript implementation have? We haven't tested in browser but the blockfrost and emurgo serialization should work in the browser.
  • Animo is creating a Rust library so all crypto, etc which should be useful with WASM for browser, etc. https://github.com/hyperledger/anoncreds-rs
  • Swift and Java and React Native support are coming
  • What would an interopathon at IIW look like?

Next steps:

Atala Prism

AnonCreds spec

  • Work being done on the revocation model list

AnonCreds rust impl

  • Replace indy-credx implementation with AnonCreds-rx
  • Move indy-wql to Aries Askar
  • Wrappers for each language

Cardano AnonCreds method thoughts?

Discussion

  • Revocation accumulator
  • Ids on chain (resources), including the hash of the transaction
  • Combine Spec models with Cardano specific fields
  • @Rodo will help define how we store this
  • All of the objects need an id, but then we can't use the hash from the transaction... instead right after publishing (accepted) with trx id.
  • Tails service
