A type of globally unique identifier, defined by a W3C standard, that is controlled by its subject and resolves to a DID document containing public keys and service endpoints, without depending on a central registry or issuing authority.

Semantic Classification

  • A decentralised identifier (DID) is a persistent identifier that an entity can create and control independently of any central authority. Each DID resolves to a DID document containing public keys and service endpoints, allowing the controller to prove control through cryptographic means.
  • Standardised by the W3C, DIDs are a building block for self-sovereign identity and verifiable credentials, supporting authentication and secure interaction where the subject, rather than an issuing platform, holds the identifier and its associated keys.
