New Senior Communications Director
Hello! I’m Damian Glover, DIF’s new senior communications director. My background is in journalism, web product management and customer strategy consulting. I've been participating in the decentralized identity community since 2019 and currently co-chair the IoT Special Interest Group, in addition to my role as communications director.

Korea SIG
We’re extremely excited to announce the formation of the new DIF Korea Special Interest Group (SIG).
The Korea SIG will provide a forum for research into domestic applications of decentralized identity and will coordinate technical standardization work, with the goal to develop a Korean-style decentralized identity ecosystem and incorporate this into the country’s e-government framework.
Participants will include representatives from the Telecommunications Technology Association (TTA), the National Information Society Agency, the Korea Internet & Security Agency and the Bank of Korea.
The Korea SIG will meet every two months, with the first meeting taking place in Busan on 19-20 July. The SIG will be chaired by Park Kyoung-Chul, CEO of K4-Security.inc, which is collaborating with the Ministry of Science and ICT to research decentralized identity. Kyoung-Chul also serves on the Blockchain & Information Security Standardization Committee within the TTA, a standards development organization.

🛠️ Working Group Updates
🔐 Applied Crypto WG
BBS Signatures
DIF members Tobias Looker and Vasilis Kalos of MATTR presented their updated Draft of the BBS specification at the Crypto Forum Research Group (CFRG) during the recent Internet Engineering Task Force (IETF) Meeting in Yokohama Japan.

📖 Open Groups at DIF
☂️ DIF Interoperability Group
The DIF Interop Working Group welcomes Bonnie Yau from the Digital Identity Lab of Canada (IDLab) as our new Chair.
The Interop WG kicked off May with a brand new series on User Adoption and Interoperability. This series is an opportunity for problem solvers and technology innovators to exchange stories on their journey thus far. For our first presenter we were pleased to welcome Dan Giurescu, founder of Credivera. Credivera is the world’s first secure, open exchange for verifiable credentials and Dan shared a great overview of his company’s journey, how they have made a positive impact in the hazardous goods industry, their ecosystem, and challenges and successes in interoperability.

[📡 DIDComm User Group] (Open Group)
Several of the DIDComm user-group members participated in a DIDComm v2 connect-a-thon at IIW. We showed several different vendor agents messaging, issuing credentials, and other DIDComm sub-protocols. Click here
for more information.
Reminder: for those who have been away from DIF for a while, the DIDComm “Unsyc” has now been reformed into the DIDComm User Group, which meets Mondays at 12 pm PT. The group is open and non-IPR protected. The group is currently discussing creating a DIDComm user guide in addition to a DIDComm testing tool, a training course, and a browser-based DIDComm-focused playground with the intention of helping the community understand and extend DIDComm v2. Feel free to join the group meeting or contribute to the discussion on Discord.

📻 IoT SIG
Tram Vo, CEO of MOBI, the smart mobility consortium, and CTO Andreas Freund recently spoke to the IoT SIG about the alliance’s technical work and how they are leveraging DIDs and VCs to enable a range of use cases within the automotive industry. We also heard from Michael Ford of IPC International, the global association of the electronics industry, on how the industry is assessing how DIDs and VCs can dovetail with existing standards for digital twins and provenance of materials in the electronics supply chain. Nicky Hickman shared insights into key IoT market segments and led a discussion on prioritising IoT-related use cases for DIDs and VCs.
The IoT SIG meets bi-weekly at 10am PT/1pm ET/ 7pm CET Wednesdays

📢 Announcements at DIF
IIW XXXVI
DIF members and friends gathered at the Computer History Museum in Mountain View, California for the 36th Internet Identity Workshop. IIW attracts an international audience and has a history of incubating important identity standards including OAuth and OpenID Connect. In the words of event co-founder and DIF Steering Committee member Kaliya Young, “The event continues to be the biggest tent for collaboration and ideation across the various user-centric identity spheres and communities. The open culture of DIF and its commitment to integrations with today’s identity technologies thrive in this environment, and many key DIF collaborations have begun or successfully recruited new participants at IIW.”
Our new Executive Director, Clare Nelson, provided an update on the Decentralized Identity Foundation (DIF):
Limari Navarrete, DIF’s Senior Director of Community Engagement and Stephen Curran from the British Columbia Government’s Digital Trust Team gave a presentation on Self-Sovereign Identity (SSI) 101:
DIF members and friends of DIF led sessions including:
- ABC’s of Writing DIDs with Universal Registrar (and how it’s different from Universal Resolver) (Ankur Banerjee of cheqd and Markus Sabadello of Danube Tech):
- Advanced Topics in DID Resolution (Ankur Banerjee and Markus Sabadello)
- Interoperable Trust Registries with DID-Linked Resources (DRLs) (Alex Tweeddale of cheqd and Andor Kesselman of Benri.io)
- 30 days from Web5: A preview of the stack and Developer Preview release next month (Daniel Buchner and Gabe Cohen of TBD)
- Using HUMOR (ha ha ha) and Visual Communication To Gain TRUST (Chance McGee and Zack Jones from Trinsic).
Notes from these and other proceedings will be published on the IIW website shortly. In the meantime here's a few post-event reflections from DIF members:
“I saw three major themes: Trust Registries/Trust Establishment, AI (and how decentralized identity may help us sort things out) and Government (many representatives in attendance and leading sessions)” Mike Ebert
“Some of the topics I found most interesting: SD-JWT - not necessarily related to any work item, but was a great topic and super informative session. Advanced Topics in DID Resolution - might want to reach out to Markus / Ankur for a synopsis, but as you might guess it covered some aspects of DID Resolution other than simply getting a DID Document (e.g. querying the historic state of a DID). Fun with DIDComm Protocols - I led this session where we brainstormed what some fun DIDComm protocols could look like. I hope to discuss this in one of the upcoming DIDComm User Group calls, but some of my favorite ideas were: Transform - a protocol for transforming DIDComm messages (e.g. from one language to another, or from text to audio); Shout - a lightweight social feed based on DIDComm; Chess - we're gonna make Chess over DIDComm happen!” Nick Reynolds
At this IIW we were fortunate to be joined by Chance McGee who brought a unique look at humor, visual representation and storytelling to the SSI space:
