Whitepaper

This paper comprehensively overviews OpenID protocols leveraging verifiable credentials. We delve into the nuances of OpenID for verifiable credential protocols like self-issued OpenID provider V2 (SIOPv2), verifiable credential issuance (OID4VCI) and OpenID for verifiable presentations (OID4VP), highlighting their pivotal roles in enhancing privacy and fortifying digital identity. Through real-world scenarios, the criticalvalues of OID4VCI and OID4VP are illustrated, emphasising their transformative potential in shaping the landscape of digital wallets, with a focus on the innovative European Union Digital Identity (EUDI) Wallets.
