In this interview, we speak with a team engaged in shaping the future of digital identity through standards-based, interoperable solutions. With a strong background in European eIDAS initiatives and conformance testing, the team shares insights into their project, DIDimo, developed under TrustChain. They discuss the motivation behind their work, the benefits it brings to the ecosystem, and how TrustChain has supported their growth and collaboration within the NGI community.
Can you briefly present your team?
We’re a team with expertise in digital identity standards, software interoperability, and conformance testing. Our experience spans European eIDAS initiatives, cryptographic systems, and open-source tool development.
How did you come up with this project idea and what benefits will it bring to the end users?
We noticed a lack of tools to help developers, issuers, and wallet providers test and demonstrate conformance with the EUDI-ARF. Credimi fills this gap by acting as a marketplace and validation platform for interoperable EUDI-ARF components.
How is TrustChain supporting your growth and what role does it play for the next steps in your development?
TrustChain has given us the opportunity to refine our prototype and engage with a network of other NGI innovators. It allows us to validate our assumptions early and ensures our tooling can be aligned with evolving specifications.
Why did you apply to the TrustChain call and has your vision changed since then?
We applied to accelerate the development of open conformance tooling for digital credential ecosystems. Our vision has remained consistent, though we now see even more potential in supporting cross-border pilots and open marketplaces for EUDI-ARF solutions.
What is the most valuable takeout from the TrustChain project and why was the topic of the Open Call important to you/your team?
The most valuable aspect has been access to feedback from domain experts and peer projects. The topic aligned well with our long-standing focus on transparency, interoperability, and standards-based digital infrastructure.
Did you establish collaboration with any of the TrustChain teams or plan for any kind of synergies? If yes, what is the biggest potential in such collaborations?
We had an ongoing collaboration with other teams from our experience in OC1, which are still ongoing today. Together with Arsys we built a use case together that we’re jointly proposing to B2B customers.
What are your expectations regarding the TrustChain software ecosystem and its contribution to the NGI priority areas?
We hope the ecosystem will encourage composability across digital identity solutions and provide a testbed for secure, user-centric infrastructure. Our expectation is that TrustChain will produce tools and libraries that accelerate NGI-aligned deployments.
What are the next steps for your team?
We’re extending support for a wider range of EUDI-ARF actors and profiles, improving test coverage, and preparing to integrate Credimi into pilot environments. We’re also planning early community onboarding and documentation.
What is the message you would give to new and potential applicants to TrustChain Open Calls?
Come with a concrete idea and a clear standards alignment. The TrustChain program offers both structure and flexibility, and is especially valuable if your work contributes to open interoperability in NGI ecosystems.
