🚀 Decentralized Identity Foundation News

Steering Committee Elections - call for nominations
The annual election of DIF Steering Committee members is approaching, with the deadline for nominations September 4.

The Steering Committee is an elected group of member representatives who lead DIF, set strategy, assure the quality of ratified work items and respond to the community’s needs. Elections occur each year to ensure a democratic process to lead and administer DIF, and to continually provide a diverse and inclusive mix of commitee members.

If you know someone who would be a good candidate, please submit their name to nominations@identity.foundation by Sept 4. Self-nominations are also fine!

The full election timetable is available on the DIF website .

Korea SIG
The Korea SIG met for the first time on 19th July in the city of Busan, designated a Blockchain Special Zone by the Korean Government.

The Kickoff event was held in conjunction with the Self-Sovereign Identity Technology Project, initiated in the first half of 2023 by the Ministry of Science and Information and Communication Technology (ICT).


Standardization committee members, professors, and industry officials gathered at the event. DIF was introduced, together with the specifications-compliant stacks being discussed at DIF, and the wider ecosystem DIF operates within.

The topic of a Legal Identity Issuance and Verification Framework for Decentralized Identifiers was introduced in preparation for further discussions at upcoming meetings, with a presentation on the topic from Professor Kim Hyun-il of Kongju University, generating considerable interest and questions.

In Korea, Decentralized Identity demonstration projects are ongoing every year, creating various application cases, but it is true that progress on technology standardization has been slow. Accordingly, DIF Korea SIG agreed to explore and further understand DIF's technology specifications and stacks through periodic meetings, contribute to the standardization of Decentralized Identity technology, and discover exemplary application cases to which DIF specifications will be applied already this year.


The next meeting of the Korea SIG will take place on 14 September at Yongsan Army Hall, hosted by the Korea Institute of Information Security & Cryptology, when DIF will be introduced at the Next Generation Authentication Research Group Workshop 2023

New DIF developer advocates
DIF welcomes Mostafa Nagy and Pratap Mridha as Volunteer Developer Advocates. Mostafa helped to recruit a number of participants for the recent successful did:hack event and both advocates will help recruit participants for a series of upcoming hackathons.

Hospitality and Travel SIG

The Hospitality & Travel SIG is hard at work on a decentralized traveller profile and schema which we hope will attract broad interest and participation from the Hospitality & Travel community.

Traveller information is today locked into narrow silos controlled by competing interests all of whom claim to own the customer. No effective data sharing arrangements exist between those parties, preventing traveller information from flowing with the traveller in transit.

While much of the interaction between travel and identity communities has to date been denominated by discussions around border crossing, credentials and trust, SSI offers equal opportunity for traveller experience improvement within the airport and downstream into transport, accommodation, and tourism. Collectively, we describe the targeted outcome as a seamless traveller journey.

Central to unlocking this opportunity is adoption of a common traveller profile and preferences.

The H&T SIG is hoping to use the DIF collaborative process to allow the widest participation in the schema definition and creation.

*The Hospitality & Travel SIG meets each Thursday 10 AM Eastern time for 1 hour


Daniel Fritz, Executive Director of the Pharmaledger Association, shared his insights into how the pharmaceutical industry is collaborating to create a digital trust ecosystem and how this is benefiting members, starting with a shared product enabling members to switch from paper to electronic Product Information leaflets.

Riho Vedler, an EU and UN expert on Logistics and Digital Transformation, also presented to the SIG on the role of decentralized identity in enabling compliance with the upcoming electronic Freight Transport Information (eFTI) regulation in the EU.

The SIG is currently considering potential work items and welcomes input from current partipants and the wider community.

The IoT SIG meets bi-weekly at 10am PT/1pm ET/ 7pm CET Wednesdays

Digital Identity unConference (DICE) Europe 2023

DIF members participated in three days of inspiration, collaboration and connection in Zurich last month as the Internet Identity Workshop (IIW) format came to Europe for the first time.


The event brought together innovative startups, large companies, and governments, who are building products and developing services using emerging digital identity technologies.

The pre-unConference day on 7th June featured presentations on both foundational and advanced Decentralized Identity topics. One of the highlights was a panel discussion in which government representatives from the UK, Finland, Bhutan, the USA, Austria and Switzerland compared notes on how each country is approaching the introduction of digital identity services.


Over the next two days of the unConference attendees proposed, discussed and co-created valuable output on a wide range of topics including DNS and Decentralized Systems, Mapping non-technical problems, How to evaluate tech stacks for future ecosystems, Digital Ethics, Interop Profiles and Experiences for OIDC4VC, Verifiable Credentials for Education, Wallet Security, Trust Registries, Connecting SSI with the Supply Chain, Requirements for Organisational Wallets, Revocation Methods and the EIDAS 2.0 EU Digital Identity Wallet Architecture Reference Framework (ARF).


Kaliya Young and Heidi Nobantu Saul, the two facilitators of IIW, collaborated with a local partner, Trust Square, and the Swiss Digital Identity and Data Sovereignty Association (DIDAS) to produce and host the event.

Identity Week Europe 2023


Several DIF members also participated in Identity Week Europe in Amsterdam last month.

The event was attended by many vendors and customers in fields such as biometrics and travel, counter document fraud, Know Your Customer (KYC) and border management.

DIF's senior director of communications, Damian Glover, participated in a panel discussion on Decentralized Identity with Marnix van den Bent from Rabobank, Raffael Knecht (Swisscom), Pedro Torres (Youverse) and Robert Garskamp (Id Next).

The session was well attended, signalling growing interest in Decentralized Identity within well-established identity-centric industries. The audience posed some interesting and challenging questions at the end of the panel discussion and it was great to engage with the wider identity and business community.
