If two decentralized services, such as a credential issuer (or a verifier) and a mobile wallet, speak different protocols or misuse an existing protocol, the problems generated from this situation can be hard to trace, would have long lasting consequences and be challenging to resolve. If we aim to democratize the development and deployment of credential issuance/verification, we need to provide tools that allow anyone to easily and independently verify the compliance of the services to one or more protocols. Born from our experience with developing the open source identity solution DIDroom, DIDimo’s main goal is to boost the market adoption of decentralized identity services, by offering anyone to test the wallets’ compliance to multiple protocols as well as a marketplace for service providers.

Briefly DIDimo will allow:
– End-users, developers or software integrators, can assess the compliance of a credential issuer/verifier to multiple standards (we aim for: SD-JWT, W3C-VC, OpenID4VCI, OpenID4VP, vc-di-bbs) by entering its endpoint in a web interface (or via API).
– Developers/Solution providers can submit their issuance/verification services to DIDimo in order to have a compliance check, receive a blue-stamp if the result is positive (or a red-flag with a list of the issues found) and to list their service in the marketplace of the platform.
– For every bluestamp, DIDimo produces a “badge” in the form of verifiable credential (W3C-VC) which can display on the website of the credential service provider (or a third party, such as participatory democracy platform, a marketplace, a social media etc.) using an iframe.
– End-users (and various stakeholders) can browse and compare the list of submitted services in the marketplace.
– End-users can provide feedback and rating of the services, adding a community driven trustworthiness on top of the technical assessment, usable by all the parties in a data exchange ecosystem.
