Project Health

The contributors to Hyperledger Indy spent this past quarter working on these key initiatives:

  1. Hyperledger INDY has graduated from incubation status.
  2. Developing reference agents so that they are usable by new participants in the ecosystem.
  3. Schema improvements are now in a proposed overview HIPE for community comment and feedback.
  4. Ursa updated to 0.1.1 which means Indy-SDK can begin using it.
  5. Major breakthroughs on Agent Interoperability with 6 independent agent implementations passing the Agent Test Suite and more discussions on Credentials Exchange and other key protocols.

Indy’s codebase has 20,000 commits from 164 unique contributors. This represents an increase of 19 contributors this quarter and nearly 3,000 additional commits. Forums and chat channels are monitored and responses to questions are frequent, timely, and helpful.

Issues

While we have resolved some issues during the past quarter, some of our top issues from last quarter continue to be our central concerns. As noted below, we continue to make useful progress.

Incompatible agent implementations

Efforts are ongoing to increase interoperability between existing agent implementations and future implementations.

Progress made:

  • 6 Independent Agent implementations are passing the Agent Test Suite.
  • Routing and Credentials tests will shortly enter the Agent Test Suite.

Further remediation planned:

  • Continue standardizing agent communication protocols, including credential exchange.

Measuring the size and make-up of our user community

We began making progress on this issue by measuring the number of developers creating solutions by contributing to indy github projects.

Progress made:

  • We are measuring GitHub contributors and can produce a week-by-week graph of contributors added over the last year.

Further remediation planned:

  • Work with Hyperledger to get analytics about web sites, and Rocket Chat usage.
  • Begin measuring usage of the Sovrin forums: new contributors, questions asked, and questions answered
  • Measure Indy tags on Stack Overflow.

Build Issues

The current Jenkins CI pipeline has become slow, bloated, and difficult to maintain and extend.

Progress made:

  • The building of client libraries and reference agents has moved to the Sovrin Foundation and this work is nearing completion.

Further remediation planned:

  • Move from Jenkins to Gitlab CI for simpler configuration, greater security, and allowing third parties to contribute build resources.

Maintainer Diversity

Indy maintainers remain active in developing and contributing to working group calls and public discussions. The bi-weekly Indy Maintainers Circle call has consistently been the medium by which maintainers coordinate work, discuss critical issues to the Indy codebase, and resolve HIPEs. The Indy Agent call continues to be the focus of much attention, and the Overlays Working Group also continues to receive a lot of interest.

Contributor Diversity

Hyperledger Indy continues to see contributions from developers and organizations around the world. Our weekly Working Group call is normally attended by two dozen people representing nearly a dozen organizations. Indy’s codebase has 20,000 commits from 164 unique contributors. This represents an increase of 19 contributors this quarter and nearly 3,000 additional commits.
