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.
