+## Project Health
+
+Things slowed down significantly on the AnonCreds project this past quarter and
+we're considering what steps to take next to change the current trajectory of
+the project. The broader issues are driven by two key issues.
+
+- The eIDAS2 / EUDI initiatives in Europe that have
+deemed that security trumps privacy, and having "selective disclosure"
+is "good enough".
+- There are various groups (including Hyperledger AnonCreds) working independently on
+  what's next after AnonCreds for maximally privacy preserving verifiable
+  credentials.
+
+On the first, there are groups in Europe that would like to see more privacy
+preserving credentials in place, but they are very much in the minority. For
+example, concerns have been raised in
+[Europe about privacy being at the heart of the European digital identity]
+efforts and in the [US by the ACLU and EFF].
+The reasons outlined are exactly why the collaborators working on AnonCreds
+continue to evolve the capabilities. It is not clear if the privacy regulators
+have weighed in on the initiatives.
+
+On the second, we see a need to try to bring together some of these groups to
+work collaboratively. The goals are the same, the underlying signature schemes
+are the same, so the question is how can we generate some synergy on the work?

+
+The [AnonCreds Quarterly Activity Dashboard] shows the activity on the project
+repositories from January to March 2024, with 45 commits and 15 contributors in
+the quarter. Those counts are down substantially from the last Quarterly Report
+(2023-Q4) and from the previous quarter (Oct-Dec 2023).

+
+## Overall Activity in the Past Quarter
+
+Coding for the quarter focused enabling the use of AnonCreds v1 in W3C
+Verifiable Credential Data Model ([VCDM]) format. This was triggered by a "Code
+With Us" procurement from BC Gov that was won by [DSR Corporation] for the
+[AnonCreds Rust] work, [Animo Solutions] for the adding support for the format
+in the [Credo-TS] and [Bifold Wallet] libraries (formerly Aries Framework
+JavaScript and Aries Bifold React Native, respectively and now part of the
+[Open Wallet Foundation]), and What's Cookin for adding support for the
+format in the [Aries Cloud Agent Python] library.

+
+As announced in the last Quarterly Report, the contribution of the new AnonCreds
+v2 code base, and underlying cryptography in [Agora], a Hyperledger Labs,
+represents a big opportunity to advance AnonCreds and the idea of maximally
+privacy-preserving verifiable credentials for everyday use. While we have
+covered the new libraries and investigated how the "proof of concept" code might
+evolve into an AnonCreds v1 replacement, to date we have had no significant
+efforts on the project. As stated in the last Quarterly Report, we need to
+assemble the set of collaborators looking to accomplish that goal that are
+willing to have developers do the work needed. Yet another presentation at
+[Internet Identity Workshop] got some interest, going over the capabilities
+enabled by AnonCreds v2, and a "[To Do List]" of things we as a community need
+to work on. However, there is still no full time development happening.
+
+Few attendees have been at the recent AnonCreds Working Group meetings.
+
+There have been additional, significant contributions of code in the Agora
+project -- [audited cryptographic libraries].

+## Current Plans
+
+Continued evolution of the [AnonCreds Rust] library. Developing marketing and
+collaboration efforts on AnonCreds V2 and the [anoncreds-v2-rs] library or
+another approach to the next generation of maximally privacy preserving
+verifiable credentials.
+
+## Maintainer Diversity
+
+Project Maintainers are from three different organizations: Animo Solutions, BC
+Gov, and SICPA, plus an individual contributor.
+
+## Contributor Diversity
+
+Contributions in the quarter have come from at least 13 different organizations.
