The Digital Identity Management Workshop took place at Reykjavik University on Wednesday, 6 August 2025.

Computer science students from Reykjavik University, researchers and professionals interested in digital identity management met at Reykjavik University on August 6th to learn about and discuss critical topics of digital identity management. Digital identity management is essential to minimize risks of data breaches and cyber threats while simultaneously enhancing regulatory requirements and process efficiency, however in practice it is an extremely hard problem to solve at scale.

Professor Jacky Mallett (Reykjavik University) welcomed the participants and gave an overview over the interaction on limits on information scaling in networks with the Fischer Consensus Problem. This was followed by a talk on the challenges of practical digital identity infrastructure and current research on potential solution approaches, presented by Jonathan E. Hochman (Yale University). Havard Mathisen (PwC Norway) introduced the participants to the FLP (Fischer-Lynch-Paterson) theorem, providing a practical approach to theory. Professor Hans P. Reiser (Reykjavik University) presented the development and the future of electronic IDs in Europe.

The keynote speech after the lunch break was given by Professor Michael J. Fischer (Professor of Computer Science at Yale University) on his contribution to one of the most seminal papers in distributed computing research: "Impossibility of Asynchronous Distributed Consensus (FLP) – a retrospective".

The final panel discussion, moderated by Professor Alice Fischer (University of New Haven), raised thoughts and ideas on information network scaling and consensus, current challenges of practical digital identity infrastructure and digital identity management. Overall, the workshop program enabled a fruitful exchange of knowledge, ideas and research and was a full success.

This workshop was hosted by the Frostbyte Lab and co-funded by the European Union through Eyvör (NCC-IS) and Defend Iceland grants.
