Session Abstract: OpenID for Verifiable Credentials (OID4VC) is a set of protocols to establish verifiable credentials expressed in any format. The power of the protocols lies in its demonstrated simplicity, security, and implementation across the tech stack - not just for credential formats, but also entity identifiers, trust models, crypto suites, revocation mechanism, etc. However, this also means that to be interoperable and enable certain use cases, implementers need to agree on the sets of choices across the tech stack, usually referred to as interoperability profiles.
In this talk, we will share implementation experience with OID4VC specifications, and introduce existing interoperability profiles based on OID4VC. We will provide updates to OID4VC specifications, given the ongoing evolution based on an overwhelming amount of implementation feedback last year.
