+## Project Health
+
+The project continues to make good progress, with the maintainers and
+contributors completing version 0.1.0 of the AnonCreds Rust implementation and
+that library being used in downstream applications.
+
+The [AnonCreds Quarterly Activity Dashboard] shows the activity on the project
+repositories, with 52 commits by 8 contributors in the quarter. Those counts are
+much lower than last quarter, reflecting the shift from implementing AnonCreds
+to using AnonCreds in the downstream implementations, including the various
+Aries components/frameworks, and applications built on Aries.
+
+> NOTE: As of 2023.08.02 only some of the AnonCreds repositories are visible on
+LFX Insights. The additional repositories are being added.

+## Questions/Issues for the TOC
+
+None.
+
+## Releases
+
+- [anoncreds-rs] -- v0.1.0-dev.13 through v0.1.0-dev.19 and v0.1.0 (final)
+- [anoncreds-clsignatures-rs] — initial release 0.1 published to crates.io
+
+
+## Overall Activity in the Past Quarter
+
+The highlight of the quarter was the completion of the 0.1.0 release of the
+Hyperledger [AnonCreds Rust] implementation and its subsequent deployment in the
+[Aries Framework JavaScript] Release 0.4.0 code base. Aries Framework JavaScript
+0.4.0 is already in use in several production environments, including in [Aries
+Bifold]-based apps released through Google Play and the iOS App Store. The Aries
+Framework JavaScript implementation supports multiple AnonCreds publication
+platforms beyond Hyperledger Indy, including at least [Cheqd.io] and [Cardano].

+
+Work on embedding the [AnonCreds Rust] implementation in [Aries Cloud Agent Python]
+has stalled, and the maintainers of that library are reorganizing that effort.
+The maintainers of the [Aries VCX] implementation recently connected with the
+AnonCreds maintainers with an offer to help with the AnonCreds implementation to
+make it easier to consume in the (Rust) Aries VCX code base.

+
+The transition of the Ursa CL Signatures library to the [AnonCreds CL
+Signatures] was completed quickly and smoothly, with a number of enhancements
+and fixes made to the library during the transition. These are the first
+enhancements to the code base in several years. For example, code optimizations
+were found that improved the revocation registry generation process by about
+50%, and the handling of other revocation processes by about 25%. Bugs in the
+library were also identified and fixed, and new releases of downstream libraries
+(including [Aries Cloud Agent Python]) published in early July (just after the
+end of the quarter).

+
+Work continued on the v1.0 specification, albeit more slowly with the alignment
+with the [AnonCreds Rust] 0.1.0 implementation complete. At the end of the
+quarter, [Aritra Bhaduri] joined the project via the Hyperledger Mentorship
+Program. Aritra is documenting the cryptographic algorithms in the specification
+and ensuring alignment with the implementation. Work continued on the v2.0
+specification, with a complete “draft” pass completed in meetings and work ready
+to start on the specification details—minus any decisions on Revocation. What to
+use for the next generation revocation scheme continues to be a challenge.

+
+## Current Plans
+
+Implementation work is focused primarily on the downstream projects that use
+Hyperledger AnonCreds. Work is continuing on improving the CL Signatures
+implementation.
+
+On the specifications side, completing the v1.0 specification is focused on the
+documentation of the cryptographic algorithms used in the processing, as
+mentioned earlier. As well, work can begin on filling in the details of the
+[AnonCreds v2.0 Specification] as a formal document.
+
+## Maintainer Diversity
+
+Project Maintainers are from three different organizations: Animo Solutions, BC
+Gov, and SICPA.
+
+## Contributor Diversity
+
+Contributions in the quarter have come from at least 8 different organizations,
+including Animo Solutions, Roots ID, 2060.io, Indicio and BC Gov.
