A W3C-standard identifier scheme that lets entities prove control of an identifier without relying on a centralised registry. A DID resolves to a DID Document containing public keys and service endpoints. VC Deal Flow Signal publishes /.well-known/did.json and /.well-known/did-configuration.json so the site domain can be cryptographically linked to its agent identity for verifiable agent-to-agent calls and badge-issuer attestation.
