Steering Committee Elections are just around the corner!

We made a quick explainer on our blog to clear up the procedure in anticipation of next month's elections.

🛠️ Group Updates

☂️ InterOp WG (cross-community)

  • Justin Richter & Adrian Gropper on newest GNAP core spec
    • GNAP = Grant Negotiation and Authorization Protocol
    • Defines a mechanism for delegating authorization to a piece of software, and conveying that delegation to the software. This delegation can include access to a set of APIs as well as information passed directly to the software.
  • Discussion on Micro-Grant/Implementation-Bounty setting by DIF for the community (ideation and planning).
  • Machine readable governance framework straw man (Telegramsam), Trust frameworks at ToiP (Sankarshan).
  • Stephen Curran gave a tour of the recently-launched cross-agent Aries test harness, and an overview of the interop landscape of Aries, the different profiles, and the Code With Us grant program to bring us closer to more full-featured interoperability with the non-Aries world.
  • Anil John and some SVIP cohort members gave a Plugathon Report-out focusing specifically on the open-sourced conformance testing aspect of the program: Slides and demos from the event, the W3C-CCG VC-HTTP-API specification, and the updated W3C-CCG/Digital Bazaar CHAPI Test Suite.
  • In other interop news from the broader community, there was also an Interop Testing Survey to gauge interest and motivation to advance DIF Member Gataca's Verifier Universal Interface and a video Guided tour of DIF member iGrant.io’s Aries Testing Journey and their open-sourced Aries Interop Playground (both done through the interop program of ESSIF-LAB).

💡 Identifiers & Discovery

  • Discussion on multisig and delegation in DID methods and verification methods:
  • New did:solid method (but not related to Solid) by DIF members Civic
    • Discussion of the mechanics of the Solana blockchain, which the method utilizes.
    • Member-run universal resolver.
  • Universal Registrar discussion.
  • DID WG: Timeline and what the current "CR" state means.
    • Review and discussion of DID WG test suite
    • Policies of DID Method Registry from last few DID-WG topic calls.

🛡️ Claims & Credentials

  • Presentation Exchange reached v1.0.0 status.
    • It is now an officialy DIF Ratified Specification
  • Work and discussion on current Credential Manifest and VC Marketplace items.
    • Credential Manifest - how issuers differ from verifiers in their publication needs and mechanisms
      • Should CM support to output multiple credentials?
    • VC Marketplace - VC business-model/marketplace-use-case sandbox/discussion group. Detailed discussions not just about payment and incentivization but also discovery mechanisms, semantic definition/propagation, and other ecosystem-scale design issues
      • the group is moving its materials into Spec-up format and editing them in a spec-ward direction
      • adding more Use-case categories to their already extensive list
  • Discussing the current status of the LDAP VC-Revocation mechanism proposed by Spherity (Germany) and AutoSeg (Brasil) as a VC data model extension.
  • Quick overview of UVI (Essif-lab), an extension of the VC-HTTP-API to help discovery and verification from a VC verifier's point of view.

🔓 DID Auth

  • DIF-OIDF joint meetings - follow along on the bitbucket issues if the timing doesn't work for you!
  • On 29th April SIOP/DIF will be represented by Kristina at the OIDF workshop.

📻 DID Comm

  • Recently merged issues
    • the long discussed 157 - JSON-LD Context
    • 167 - property to accept media type
    • 171 - media type discussion
    • 166 - to support Curve P-384
  • Repository restructure to fix image display in the spec - 170
    • DIF Blog post on how to use Spec-Up coming soon!
  • Still open issues
  • Revisited issues
    • 165 - cty of JWM
    • 162 - Rewrapping forwarded messages. - awaiting PR
  • Peer DID Method 2 produced some good questions and was eventually merged - pull 26

📦 Secure Data Storage

  • Secure Data Storage Features:
    • EDV Client Features.
    • EDV Server Features.
    • HUB Features.
    • Decentralized Twitter (Dewitter) Requirements List:
      • Assumptions, Principles, Requirements, and Other Considerations.
  • Confidential Storage Specification Refactoring


  • Steady improvement and extension of the Q&A document keeps going in parallel to the spec/whitepaper and the implementations
  • KERI is moving from a first-cut "promiscuous mode" proof of concept to the next stage of development: securing an internal interface for local events to protect a controller's authoritative key event log from contamination by potentially malicious external events and receipts.
    • This entails designing a query mechanism for communicating requests for key events that manages the multisig escrow and the duplicity-detection log key
  • Threads to follow on github:
    • Query Mode discussion (a whopper!)
    • roadmapping thread thread
    • A conceptual/mental-model alignment thread on how the concept of the transaction-event log "TEL" is evolving as KERI gets more complex and starts layering on security, duplicity/corruption-detection, multi-sig, etc.

  • Discussion on Wallet Security WG:
  • Product intros: GlobalID, Serto.
  • DHS SVIP Interoperability update: Deck, Transmute post.

🪙 Finance & Banking SIG

Drilling down: Co-Development

Having gone over the subtleties and complexities of open-source software and open standards in general, we will now drill down into how exactly DIF advances both, in the form of a “Frequently Asked Questions” (FAQ) document. In this FAQ, we'll cover what co-development means in general, at DIF, beyond DIF, and in legal terms. Co-development isn't just in the DNA of DIF-- DIF's primary purpose is to set the stage for co-development, because we feel it's the fastest way forward to adoption and evolution of our field.

Steering Committee Elections are just around the corner!

We made a quick explainer on our blog to clear up the procedure in anticipation of next month's elections.

Sidetree has reached v1 status!

After years of robust collaboration and hard work, the Sidetree Protocol has been iterated and specified to a DIF's standards. If you have a hazy notion of what Sidetree is and how it compares to "regular" DID Methods and blockchains, now might be a good time to read our new blog post outlining the major implementations and showcasing the contributing companies.
