#50 - OpenID4VC: OpenID for Verifiable Credentials (with Torsten Lodderstedt)
Dr.-Ing. Torsten Lodderstedt is founder of Tuconic, a consulting firm specialising in digital identity and API-based software architectures, with more than 15 years experience in developing and running large scale consumer identity services. In his previous positions, he helped organisations in public, banking, railway communication, and telecommunication domains to implement highly-scalable and secure services. Torsten regularly contributes to identity standards, currently focusing on decentralized identity and global identity networks. He is co-author of OpenID for Verifiable Credentials and OAuth 2.1, and co-chairs the GAIN PoC community group. About Podcast Episode Read more about the episode by heading to https://northernblock.io/open-id-4-vc-openid-for-verifiable-credentials/ Some of the key topics covered during this episode with Torsten are: OpenID4VC’s background, and its relationship to oAuth2 and OpenID Connect. How verifiable credential issuances and verifications are done using OpenID4CI and OIDC4VP (+ why Presentation Exchange was chosen as the verification protocol). Decisions behind supporting different credentials formats, identifiers, cryptography suites and trust management mechanisms. How OpenID4VC fits within the ToIP Hourglass Model (from the ToIP Technical Architecture Specification). How OpenID4VC can be used in conjunction with other protocols such as DIDComm to bootstrap workflows. Does OpenID4VC combined with trust frameworks help to solve the NASCAR problem we face today on the internet? SIOP: the protocol to exchange cryptographically verifiable identifiers and authenticate using the key material controlled by the End-User. Using OpenID4CI for ISO 18013-5 (mDL) to move away from wallet-specific credential issuance and towards an interoperable way of exchanging verifiable credentials between different decentralized identity systems.
