DID
Decentralized Identifier
A W3C identifier scheme that lets a subject own and prove a stable identity without depending on a central registry.
A DID looks like did:method:identifier — for example did:web:smartlinks.app. It resolves to a DID Document containing public keys and service endpoints, controlled by the subject itself rather than a central registrar.
DIDs pair naturally with Verifiable Credentials: an issuer's DID signs a VC, a verifier checks the signature against the DID Document. For DPPs this gives a path to credentials that survive the brand changing platforms.
