  • Proposal for Hyperledger AnonCreds to be a top level project is here.  Please review, comment and if you support this, and your name to the sponsor list.
  • AnonCreds on ledgers other than Indy – now up to 6 independent implementations.  Working in the spec. group on making that easier.
  • AnonCreds in W3C VC Data Model standard.  Seems to be not very difficult to do.  Working on a proposal to share for putting an AnonCreds VC into W3C format (and reverse) and the same for an AnonCreds presentation into W3C VC (or VP) Data Model format.
