Distribute Distributed Identity (DI) presents an interesting paradigm for the T&I NREN community. Its concepts are very appealing and align well with public values in our community. At the same time many of the technical and functional properties are still in development and present numerous questions and challenges, as was shown in recent work in NRENs and in the Incubator.

The activity proposed builds on earlier work and investigates the following aspects of DI:

1. What roles could/should GEANT and NRENs play in a DI ecosystem, and what are the associated benefits, challenges and risks?

2. Which current services in the GEANT portfolio would benefit from the use of DI, and what would that look like?

3. To what extent can existing initiatives implementing distributed ledgers technology be used to act as a Verifyable Data Registry to satisfy the above use cases and requirements? We should test with for example EBSI, etherium or Sovrin. How do these compare to the IRMA solution we previously tested. (IRMA does not use DLT).

4. Initial testing with IRMA revealed a wallet based approach may not always provide an optimal user experience. What requirements do we have for the User interface (wallet/app) and can we implement or mock these to test these requirements with stakeholders.

• Conduct interviews with stakeholders
• Describe report based on use cases

This activity

published a Report on DI for GÉANT, NRENs and institutions. It was presented at multiple events like the Incubator demo or the Task Force Distributed Ledger Technologies.
