Concepts

This section covers the protocols and patterns that underpin EUDIStack. It is not a digital identity course — it is the minimum foundation you need to integrate correctly.

  • OID4VCI

    OpenID for Verifiable Credential Issuance. How a credential is issued to the wallet.

  • OID4VP

    OpenID for Verifiable Presentations. How the wallet presents credentials to a verifier.

  • SD-JWT VC

    Selective Disclosure JWT — the default credential format used by EUDIStack.

  • DPoP & PKCE

    How token possession is proved and code exchange is protected.

  • Multi-tenant

    How each customer is isolated in EUDIStack and what that means for your integration.
