Agenda

• Oracle Labs progress report on a higher layer abstraction based on AnonCreds v2 and other signature schemes – Mark, Harold
• Status updates from current work:
  • Revocation Manager for ALLOSAUR Project – Hyperledger Mentorship project being executed by VictorH2208Project plan
  • MPC part of ALLOSAUR is done – Mike – oblivious transfer and homomorphic – possibly a separate repo – Beaver Triples (based on "Beaver's Trick" from the 90s) – public component and ABC – proving A*B = C – simplifies communications.
  • Updates on Agora contributions and audits
    • Verifiable secret sharing – almost ready to contribute, will update Genaro with the same changes and contribute soon. End of week???  Maybe...
• Moving AnonCreds to the Decentralized Identity Foundation (DIF)?  Considering it...
• Open Discussion
