• OpenID 4 Verifiable Credential Issuance (OpenID4VCI) is a standards track specification being developed at the OpenID Foundation for issuance of verifiable credentials into wallets.
• Demonstrated interoperability between 9 independent issuers and 8 wallet implementations as a part of this plugfest. The results also test key extensibility points of the specification including
• Different verifiable credential formats/proofs (LDP-VC and JWT-VC)
• Different crypto algorithms (ES256, ES256k, EdDSA etc.)
• Different issuer identifiers/did methods (did:jwk, did:key, did:web…)
• Different holder binding methods (did methods)
