SIDI (Sustainable & Interoperable Digital Identity) Hub Summit

DIF joined our partners in the digital identity ecosystem, plus international organizations, standards bodies and governments from around the world in Paris this week, to work on a major challenge: how to achieve interoperability between digital identity systems.

The first Sustainable & Interoperable Digital Identity (SIDI) Hub Summit took the form of a hands-on workshop to identify and tackle the key considerations for global interoperability.

The event opened with presentations from the French government, the National Identity Management Commission of Nigeria and the event sponsors.

Following the introductory presentations, participants broke out into strategy and technical tracks. DIF Steering Committee member Markus Sabadello and Senior Director of Communications Damian Glover joined the technical track. Our group began by considering whether interoperability between digital identity systems should be underpinned by bilateral or multilateral agreements.

We went on to assess options for protocol interoperability, other technical requirements and implementation tactics.

In the afternoon participants reconvened to hear a summary of each track's work, learn about some current initiatives to increase interoperability, and identify key tactics and future work streams.

After the event, we had the chance to get to know the other participants over dinner and drinks at Mama Shelter.

The summit marks the start on an going process of engagement and collaboration between national identity programs, multilateral organisations, international development agencies, standards bodies and the digital identity ecosystem, including OpenID Foundation, Open Wallet Foundation, Trust over IP Foundation, FIDO Alliance, the Open Identity Exchange (OIX) and DIF, to accelerate progress towards global interoperability.

As one of the event organizers, DIF was thrilled to participate in the launch, and we look forward to continuing to work with our partners to address the shared challenges we all face in the digital identity community.

Korea Blockchain Grand Week 2023

DIF's collaboration with Korea continues to grow. Our Executive Director, Clare Nelson, gave a keynote presentation at Korea Blockchain Grand Week 2023 on DIF's role and future plans, and the future direction of Decentralized Identity, with Markus Sabadello presenting on Blockchain R&D in the IITP (Institute of Information & Communications Technology Planning & Evaluation) stream.

Meanwhile, K4 Security and Danube Tech GmbH announced a strategic partnership to create a joint presence in Korea that utilizes Danube Tech’s products and technologies, and K4 Security’s reputation and relationships in the Korean market. The service will be especially focused on interoperability of Decentralized Identifiers and Verifiable Credentials between Korean based identity networks and European networks. Danube Tech CEO Markus Sabadello serves on DIF’s steering committee, while K4 Security CEO Kyoungchul Park chairs the DIF Korea Special Interest Group (SIG). The partnership highlights the progress being made by the SIG in fostering international collaboration around Decentralized Identity.

Veramo comes to DIF

One of last month's undoubted highlights was the donation of Veramo, a popular JavaScript framework for verifiable data, by ConsenSys Mesh to DIF.

Steering Committee member Ankur Banerjee told the Newsletter that Veramo consolidates and extends existing DIF libraries into a powerful suite of tools that can slash the time it takes developers to incorporate Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs) into applications.

A new DIF working group is being established to steer the ongoing development and maintenance of the code base. Please contact Nick Reynolds or Mircea Nistor if you’re interested in participating. 

China Special Interest Group (SIG)
The DIF China SIG has documented its vision, targets and working plans (which are being translated into English and will be published soon), has begun outreach to recruit members, and is planning its first meeting.

The China SIG aims to promote and advocate for the adoption and implementation of DIF technologies and related W3C standards in China, and to provide a platform for communication and cooperation between China and other countries.

DIF announced the formation of the China SIG earlier this month. You can read more about the SIG's goals and related projects here, or follow the SIG's Chinese WeChat channel here.

📖 Open Groups at DIF

DIF Interoperability Group

The Interoperability Open Group is refreshing its charter to better serve DIF Members and open group participants. Sessions are on pause while the co-chairs gather feedback and review potential activities to be included in the new charter. If you have any ideas or suggestions, please reach out to group co-chairs Bonnie Yau, Brent Shambaugh or Elena Dumitrascu on Slack.

In the meantime, Bonnie provided a round-up of interoperability topics at recent events:

Identity Week Americas in Washington, DC, was a dedicated event focusing on digital identity solutions tailored for government applications. Key themes for the year covered various aspects such as digital identity, biometrics, digital onboarding, verification/authentication, secure credentials, and verifiable credentials. The two-day event revolved around the overarching theme that digital identity is transitioning into a comprehensive, large-scale implementation. A significant focus was on Decentralized Identity, ranging from blockchain solutions to discussions about verifiable credentials. The presentations were policy-oriented, featuring esteemed speakers from organizations like DHS, UN, the Canadian Government, and the EU. These speakers emphasized the importance of collaboration and interoperability as essential goals to facilitate seamless citizen travel, international work, and the establishment of trust in online interactions.

The Internet Identity Workshop in Mountain View, California, centered around technological advancements in decentralized digital identity solutions. Spanning three days, the event delved into key topics, including OpenID4VC, AnnonCreds 2, W3C, TrustOverIP, DIDComm, JSON-LD, KERI, GLEIF's VLEI, decentralized ecosystem governance, backup and restore, and credential recovery. For credential recovery, the discussions offered a comprehensive solution that encompasses defining the data format, experimenting with compression and encryption, and ensuring the compressed format remains developer-friendly. Additionally, conversations surrounding backup and recovery focused on standardizing methods for backing up application data, especially wallet data, to provide users with a seamless experience. This included challenges like backing up specific information, and the need to reissue credentials in certain scenarios (see below for more from DIF @ IIW).

The Interoperability Group meets bi-weekly at 8am PT/11am ET/5pm CET Wednesdays

📡 DIDComm User Group

The DIDComm Demo is live! This brand new app allows you to connect to another person, a computer, a phone or simply another window in a different browser tab so you can see DIDComm messages traverse back and forth after the messages have been decrypted. 

The app was developed at Indicio, with the goal to allow people to see how DIDComm works without needing to sift through or learn a substantial stack like Hyperledger Aries Cloud Agent Python (ACA-Py).

Why not try it out for yourself . You’ll see a Help button there with a tutorial, plus a link to the GitHub repo. 

The DIDComm user group meets weekly at 12pm PT/3pm ET/ 9pm CET Mondays

🗓️ ️Community Events

Internet Identity Workshop

IIW returned to the Computer History Museum in Mountain View, California in October, with DIF as an official sponsor for the first time.

IIW is where the decentralized identity community and wider technology ecosystem come together to progress ongoing topics and kick-start new initiatives.

Many DIF member organizations and steering committee members participated. Session topics included the DIF Hackathon, convened by our Senior Director of Community Engagement, Limari Navarrete (pictured below with did:hack winners Moises Jaramillo and Dixita Sharegar), Introductions to DIDComm and Trust Establishment by Sam Curren, and Presentation Exchange (Mike Jones).

Steve McCown gave a presentation on how to use DIDComm to protect files stored on cloud storage platforms such as dropbox, icloud, gdrive, etc.

"The general idea is that a process synchronizes changes (while encrypting/decrypting) between a new folder of mine and say the local dropbox folder, which in turn syncs to the cloud. My goals were: demo an alternative DIDComm use case, avoid using cloud provider APIs, and local control the crypto keys", Steve said.

Check out Steve's presentation, and the source repo.

Onyx Hackathon

The Digital Identity Hackathon, sponsored by Onyx by JP Morgan, wrapped up last month.

Category winner, and longstanding DIF contributor Kim Hamilton-Duffy added SD-JWT support and two DID methods (did:web and did:pkh) to the Onyx SDK.

"There were impressive submissions all around, using VCs, DIDs, ZKPs to pull off end-to-end user scenarios with great user experiences. I recommend checking out Onyx's decentralized identity SDK. It's based on principles similar to those we used in Verite, optimizing for interoperability and accessibility. Plus, nice, clean abstractions and design all around" she said.

Other prizewinners included Verifiable Credential ZK Health Records, which integrates DIDs and VCs with advanced zero-knowledge proofs to streamline the exchange of electronic health records across systems while adhering to healthcare standards like FHIR, Product Passport, a system to track wallet addresses and their associated decentralized identifiers (DIDs), enhancing the security of location tracking through private broadcasts and Business Network, an app designed for various professionals to find trustworthy partners through feedback from peers, which utilizes Onyx SSI for creating verified, confidential presentations that users can share to establish credibility.

Thanks to Markus Sabadello and Sam Curren for their well-attended and highly engaged sessions introducing key Decentralized Identity concepts to participants before the Hackathon got underway. You can catch their sessions here and here.
