🚀 Decentralized Identity Foundation News
DIF Labs Beta Cohort 2 RFP is here!
Exciting news for identity innovators! DIF Labs has just announced their request for proposals for Beta Cohort 2, focused on driving high-leverage work at the intersection of identity, trust, and emerging technologies. The program seeks proposals from builders and researchers in five key focus areas: Personhood Credentials, Content Authenticity and Assertions, Applied Cryptography, Verifiable AI, and Industry-Aligned Applications. Project leads must be DIF members, with proposals due by May 20, 2025. Selected projects will receive mentorship, ecosystem support, and collaboration opportunities over a 2-3 month development period. For complete details on submission requirements, evaluation criteria, and the application process, visit the full announcement on the DIF Labs website.
DIF Hospitality & Travel Working Group is Live
The Decentralized Identity Foundation (DIF) has launched a new Hospitality & Travel Working Group focused on developing standards for self-sovereign data exchange in the travel industry. This initiative will create frameworks allowing travelers to control their personal information while enabling seamless interactions with service providers. Led by chair Douglas Rice, the group will address traveler profiles, data portability, and interoperability across the travel ecosystem. For more details, see DIF's announcement:
Algorand Releases the Universal Chess Passport
Algorand has partnered with World Chess to develop a "Universal Chess Passport" using blockchain-based digital identity and verifiable credentials technology. This innovative system will allow chess players to maintain portable digital identities and credentials across platforms, enabling them to seamlessly transfer their achievements, rankings, and records between online platforms and in-person tournaments. The proposal aims to address fragmentation in the chess ecosystem while maintaining privacy and security through decentralized identifiers (DIDs). A live discussion about the initiative will be held on May 6th featuring representatives from Algorand, World Chess, and the Decentralized Identity Foundation.

Hospitality & Travel Working Group
The newly-launched Hospitality & Travel Working Group started strong. They discussed their draft implementation guide and schema development, exploring the complexities of travel stages and verifiable data. They refined key terms in their glossary, including standardizing on the term "HATPro" (hospitality and travel profile). The team aims to have a substantial portion of the schema ready to announce at the HITEC Conference in mid-June.
Creator Assertions Working Group
The Creator Assertions Working Group held productive meetings in both Americas/EU and APAC time zones this month. Discussions focused on identity claims, trust profiles, and collaboration with external groups including the JPEG Trust Group and Project Origin. The group is preparing three assertion specs for approval and considering integrating first-person credentials. The group will soon hold an election for co-chairs, with Scott Perry and Alex Tweeddale as candidates.
DID Methods Working Group
The DID Methods Working Group finalized the DIF recommended methods process, agreeing to use "DIF Recommended" consistently throughout their documentation. They heard a detailed presentation on DID Peer version 4, exploring its features and advantages over other methods. The group also decided to dedicate full sessions to DID method deep dives as practice runs for their evaluation process.
Identifiers and Discovery Working Group
The DID Traits team is preparing to release version 1.0 of their specification, focusing on making traits enable easier assessment. They're adding new traits including key validation and long-term availability, while improving terminology for clarity. The team removed software trade references due to complexity and expressed satisfaction with their progress toward the 1.0 milestone.
The did:webvh team is finalizing their 1.0 specification, including updates to examples and clarification of terminology. They addressed concerns about performance with large logs, cryptographic agility, and improving DID availability through watchers. The team is developing a JSON schema for data model validation and planning a test suite, while seeking acknowledgement from the DIF Technical Steering Committee for the 1.0 release.
🪪 Claims & Credentials Working Group
The Credential Schemas team developed a new schema directory structure with community schemas, draft schemas, and recommended schemas folders to better organize their work. They refined the proof of age schema, including improvements to boolean threshold indicators and simplifying schema names for clarity and reuse. The team welcomed new members and discussed potential synergy with the Oasis working group.
Applied Crypto Working Group
The BBS+ team focused on pseudonym implementations and designing approaches for everlasting unlinkability in credential systems. They considered trade-offs between post-quantum security and privacy, concluding that their baseline approach with pseudonyms offers preferable privacy protections. Team members are exploring the potential of using Rust instead of C++ for implementation and plan to interact more with the CFRG to advance the project.
DIF Labs Working Group
DIF Labs has launched its RFP for Beta Cohort 2. Read more here
DIDComm Working Group
The DIDComm team discussed implementing binary encoding in the next version, proposing either a DIDComm version 3 with built-in binary encoding or adding optional seabore envelopes in version 2.2. They welcomed new member SwissSafe who expressed interest in contributing to standardizing CBOR for DIDcomm messaging. The team agreed to implement a flag designator in the header for different encodings.

DIF Hospitality & Travel SIG
The H&T SIG held multiple productive sessions in April. One meeting featured representatives from the European Digital Identity Wallet Consortium who presented on the EUDI wallet's development and potential applications in travel and hospitality. Another session discussed food model development, trip profile components, and context-specific preferences for travelers. The team continues refining their implementation guide and developing a comprehensive strategy for travel wallets that support personalization, with plans to showcase their schema at the HITEC Conference in mid-June.
DIF China SIG
APAC/ASEAN Discussion Group
The APAC/ASEAN call featured a presentation on the Verifiable Legal Entity Identifier (vLEI) and its relation to the Global Legal Entity Identifier Foundation. Steering Committee member Catherine Nabbala of Finema, a qualified vLEI issuer, detailed the vLEI ecosystem governance framework and verification processes. The group discussed implementation challenges including key management, wallet technologies, and potential applications in various industries. Participants showed particular interest in how vLEI could be integrated with traditional SSI architecture using did:webs
DIF Africa SIG
The DIF Africa SIG hosted a presentation by Karla McKenna on the Global Legal Entity Identifier Foundation (GLEIF) and Verifiable Legal Entity Identifier (vLEI). Karla discussed organizational identity in the digital world and potential applications of vLEI in various sectors. The meeting explored the process of becoming a qualified vLEI issuer and how such technology could benefit government and public services. Participants expressed interest in applying these concepts to streamline business processes, particularly in Africa.
DIF Japan SIG
The Japan SIG discussed NodeX's migration from Sidetree to the did:webvh method due to concerns about content-addressable storage stability, Bitcoin network performance, and Sidetree maintenance status. Technical discussions included DID structure, the resolve process, did:webvh method advantages, and IoT device authentication and trust. The team also explored global deployment strategies and trust framework implementation, particularly for IoT devices in critical infrastructure and energy sectors.
DIF Korea SIG
📖 DIF User Group Updates
DIDComm User Group
The DIDComm User Group explored Colton's WebRTC project that enabled browser-to-browser voice communication over DIDComm. Members discussed binary encoding implementation options for DIDComm messages, focusing on CBOR while keeping the door open to other encodings. The group also demonstrated a chat system using DIDComm's mediator capabilities for seamless communication between users, even when offline. Future discussions will focus on use case documentation templates and integrating with AI-related protocols like the Model Context Protocol.
