Project Health

Limited progress was made on the "next generation" AnonCreds project in the quarter -- anoncreds-v2-rs. Contributions to the Hyperledger Labs Agora project continued. Agora includes the audited cryptographic libraries upon which AnonCreds V2 is built. A Hyperledger Mentorship project has resulted in the creation of an implementation of the scalable, privacy preserving ALLOSAUR revocation scheme that is used in AnonCreds v2.

The AnonCreds Quarterly Activity Dashboard shows the activity on the project repositories from July to September 2024.

Attendance at the AnonCreds Working Group meetings has been low this quarter.

Questions/Issues for the TAC

None.

Releases

Overall Activity in the Past Quarter

There have been additional, significant contributions of code in the Hyperledger Labs Agora project -- audited cryptographic libraries.

Current Plans

Completion of the new Revocation Manager Hyperledger Mentorship project. That includes seeing where that implementation might be useful in AnonCreds v2 and beyond.

Contributing to the conversation happening in the broader community about new ways to use ZKPs for achieving unlinkable VCs, and determining how to leverage that work into expanding efforts on AnonCreds, or using the resources of AnonCreds together with those efforts.

Collaborating with a team for Oracle Labs in creating a ZKP abstraction layer that isolates VC operations (issuing credentials, creating presentations, and verifying presentations) from the cryptographic libraries used in specific implementations.

Maintainer Diversity

After the recent cleanup of inactive Hyperledger Maintainers, the AnonCreds project now has nine maintainers from seven different organizations.

Contributor Diversity

LFX Insights seems to suggest there have been contributions in the quarter from at least 3 different organizations.
