🛠️ Group Updates

☂️ InterOp WG (cross-community)

  • 8 Dec
    • Dmitri Zagidulin presented on QR-code initiation.
  • 24 Nov
    • Do we want to define an interop profile for the community?
    • Need for a clearer roadmap:
    • Drafted a shorter cleaner version
    • This is based on an older version here
    • Call for feedback & comments from membership
  • 10 Nov
    • Presentation (recording link) from Hakan (Technical University Berlin), Andreas Freitag (Jolocom) and Eugeniu Rusu (Jolocom) to hear from the German community about how they have approached interop. This builds on a conversation started during IIW33.
    • Main topics covered include:
      • What is the core connector for interoperability?
      • One profile that works across the consortias
      • How does this work with EU initiatives? Should all countries deliver a wallet that is interoperable?
      • The interoperability matrix they are working on: here
      • Approaches to testing
      • Taking inspiration from the Aries test harness
  • Unfortunately, the October-November Updates for Interop were missing from our last newsletter, #23. We apologize and include them here:
    • Library polooza followup meeting
    • IIW recap session
      • maturity of the ecosystem
      • discussion on KERI vs DIDcomm
      • Govt direction is not completely aligned with tech direction
  • Interop group is not IP protected and the current status of the charter is here.

💡 Identifiers & Discovery

  • Continued discussion of did:keri and relation to other DID methods
  • Work items:
    • Type of identifiers this method supports and their intended use-cases (e.g., did:key)
    • How to incept KERI-based DIDs and DID Documents with multiple keys associated with them
    • KERI and did:peer - efforts to align
    • How does the method prove uniqeuness?
    • KERI is described in a whitepaper: Need to summarise the core concepts and processing rules
    • How are witnesses defined? (public keys)
    • Implementation maturity?
      • Implementation by Jolocom (in Rust) - implements the core
      • Other implementations - GO, Javascript
    • did:oyd method introduction
      • Content-based addressing, does not rely on a blockchain, using event log for updates
      • Content-based addressing (verifiable mapping between DID and DID Document)
      • Present 3 artefacts of did:oyd: DID, DID Document, Log (events)
      • Presentation of the Create/Update/Deactivate methods
      • Presentation of the cloning method

🛡️ Claims & Credentials

  • 10th Dec - ESSIF-LAB Consent Record Demo - YouTube recording
    • Data Agreement demos from NGI ESSIF-LAB sub-grantees iGrant.io, Gataca and the Human Colossus Foundation. These three demo'd implementations demonstrate how a consent notice (or "data agreement" as it was called in the ESSIF-LAB context) gets signed as a shared record between issuers/verifiers (data controllers) and holders (data subjects). The data agreement sets a clear purpose of usage, what personal data is collected, how long data can be retained and on what lawful basis it can be processed; both parties keep a record, allowing precise GDPR enforcement and transparency on all sides.
      • The data agreement was originally based on the Kantara Initiative's Consent Notice, which is now being standardized as a new ISO standard 27560.
  • Juan Caballero stepping up as C&C chair
  • JWS Test Suite (notes): test-by-test consequences of "instead of or in addition to" ambiguity in JWT expression of credentials as defined by the JWT section of the VC data model v1.1
    • swift progress on Issuance extension
    • BBS+ blocking both presentation and issuance now
  • PE (2.0) + Credential Manifest
    • PE v2 moving forward
    • At last CM meeting, PE mostly pre-empted (works around OIDF usage)
  • Verifier Universal Interface (VUI) tracking
    • Waiting for sign-off on IPR from all donors still?

🔓 DID Auth

📻 DIDcomm

  • The DIDComm Group would like to thank outgoing chairs, Tobias & Oliver for all of their past dedication and support, and take the opportunity to welcome incoming chair, Steve McCown.
  • Meetings canceled: Dec 20, 27, and Jan 3
  • Next meeting 10th Jan 2022
  • DIDComm-js Repo Archive
  • DIDComm & Hub Discussion: Scope and Organization
  • Discover Features v2 PR313
  • From in OOB PR314
    • typ in wrong places? (Sam)
  • PR Needed Issues
  • Call to Participate - DIDComm User Group
    • Now that the DIDComm v2 spec is nearing completion, and there are robust libraries in multiple programming languages, we are starting a user group to share learnings as we put DIDComm into production. We will organize community resources, produce a handbook, foster application-level protocol creation, maintain the didcomm.org website and repo, and recommend best practices. We invite anyone who's interested to register in the user group's email list here or Discord channel here.
    • The first regular meeting will be held on January 10th-14th, with meeting selection to happen prior on the above communication methods.
    • Although this UG is sponsored by DIF, this is not an IP-protected context. We won't be developing specs or working on standards. Thus, you don't have to be a member of any particular org to join, and there are no legal terms to review or paperwork to sign. Please join us!


  • Status update for did:keri, and plans to add it as a work item to the ID WG.
    • Information and contextual documents
    • Current did:keri method specification
    • Current status of did:keri
      • The goal is to continue and further expand the work on the DID method specification, to figure out how all the KERI building blocks can be utilized together in a method spec.
      • Does did:keri by itself make sense, or only "KERI in the context of an existing DID method" (e.g. did:indy:keri)?
      • The work in the KERI WG is in a special state. The goal is to "wrap up" that current status of KERI so that the KERI spec work goes into a "sleep" state. There are two communities, one working in the Trust-over-IP Foundation (ToIP), one working at DIF.
      • The proposal is to contribute the KERI work itself to the Applied Cryptography Working Group, and the did:keri work to the Identifiers & Discovery Working Group.

NGI Open Calls (EU)

  • Funding is allocated to projects using short research cycles targeting the most promising ideas. Each of the selected projects pursues its own objectives, while the NGI RIAs provide the program logic and vision, technical support, coaching and mentoring, to ensure that projects contribute towards a significant advancement of research and innovation in the NGI initiative.
  • The focus is on advanced concepts and technologies that link to relevant use cases, and that can have an impact on the market and society overall. Applications and services that innovate without a research component are not covered by this model.
  • Varying amounts of funding. Learn more here.

Hyperledger Aries

  • To anyone in the Aries Community that either builds Frameworks or deploys Aries solutions:
    • Many of in the Aries community want to transition from using the "early days" RFC 0160 Connections protocol (part of AIP 1.0) to the newer RFC 0023 DID Exchange and RFC 0434 Out of Band protocols. A "community upgrade" has been proposed that will accomplish that in a way that we can avoid periods of instability between Aries agents (Issuers, Verifiers, Wallets, etc.) if we coordinate a series of changes in our deployments.
    • A PR has been proposed to RFC 0496 (Transition to OOB and DID Exchange) and is expected to be accepted that will move us to Stage 1 of the transition, where all implementations are to be updated to accept requests using both the older Connections and newer DID Exchange protocols. During that period, all deployments will continue ONLY to send requests using the older Connections protocol. Please see RFC 0496 for the details of the entire transition.
  • The Aries Working Group is requesting that all deployments of Aries:
    • Support this transition
    • Update their code bases and deployments to achieve Step 1 of the transition.
    • Document their completion of that Step in the RFC (per instructions).
    • Monitor the conversation around RFC 0496 to be ready to go to Step 2 of the transition.
  • Please direct any questions to the Aries channel in Hyperledger RocketChat.
