Transatlantic SSI Interop

In this experiment, we demonstrated interoperability of experimental decentralized identity infrastructures in the US and EU and showed how the digital identity credentials can be exchanged between the two sides.





Additional Info

On the US side, our partner Digital Bazaar has set up infrastructure for issuing digital Permanent Resident Cards, as envisioned by the US Department of Homeland Security’s (DHS) Silicon Valley Innovation Program (SVIP). In the EU, we issued digital diplomas using the pre-production European Blockchain Service Infrastructure (EBSI). In the experiment, we successfully showed how the US- and EU-issued digital identity credentials can be exchanged between the two sides.
The concept behind this experiment was to demonstrate interoperability in the area of the emerging Self-Sovereign Identity (SSI) concept, building on top of infrastructures that are being developed in the US and the EU. SSI is clearly emerging as a next-generation paradigm for digital identity that enables independence, privacy, security, and human dignity for individuals, as well as new opportunities for digital identity of organizations and things. This approach is based on inherently decentralized architectures that eliminate dependencies on centralized authorities.

Enduser Relevance

In this project, we connected SSI infrastructures in the US and the EU, and we demonstrated that decentralized digital identity based on open standards can be globally interoperable and connected.
