Welcome, Introductions and Announcements

• Dave McKay – verid.id and DigiCred have funded for a project for the State of NC, using Traction and Bifold.

  • Wants to contribute “Kanon” (Sanskrit for “Truth”) – a new VDR private Ethereum network, and storage – alternative to askar for secure storage, but use encrypted storage.

    • Options – Hedera (see new option), Indy Besu is another option.

    • Another difference – Kanon will be using smart contracts for revocation.

• AnonCreds Webinar – March 25, 2025 – https://www.meetup.com/lfdt-sf/events/306421109/

Agenda

• Status: Completing the deprecation of the AIP 1.0 Protocols – Issue Credential v1, Present Proof v1.

  • Complete/merge ACA-Py PR #3252.

  • Complete/merge ACA-Py Plugins PR 1056

  • OATH Testing Update to use plugins and make sure everything still works.

  • Traction verification with the use of the plugins.

• Other PRs and Issues

  • New LTS?

    • Idea – add a label “LTS” to signify a PR or Issue that should be backported.

  • AnonCreds vs Anoncreds?

  • Wallet type – askar vs. askar-anoncreds – what is the difference?

    • askar-anoncreds uses the newer anoncreds-rs implementation of AnonCreds that aligns with the spec.

    • askar-anoncreds requires the use of the /anoncreds endpoints, instead of the older, per object endpoints (e.g. /schema, /credef). The issue and presentation endpoints are the same for both.

    • Existing askar AnonCreds objects are slightly tweaked in storage when migrated to the askar-anoncreds wallet type. A few tweaks, but mostly the same.

    • A new Controller app should use askar-anoncreds and the /anoncreds endpoints.

    • An existing Controller app would have to be updated to use askar-anoncreds, but changing code to use the new /anoncreds endpoint, and during initialization, to use the "migrate-to-askar-anoncreds" endpoint (not sure of the name). The first time it is run, it converts all existing AnonCreds objects stored to the new format. Invocations run sequentially (one at a time) and after the upgrade, nothing is done by all other calls. Thus, it is safe to include in the initialization of all Controller instances.

    • The wallet-type is designed so that controllers sharing a multi-tenant wallet can upgrade independently. There is no need for all controllers to be updated at the same time.

  • What to do with #3347 - enabling range proofs.

  • Panic at the Askar (Issue #3540 )

  • Status #3436? VCDM 2.0

  • Continue with #3332 in light of desire to move to loguru?
