Decentralized Identifier (DID)
Decentralized identifiers (DIDs) are a new type of identifier that enables verifiable, decentralized digital identity. A DID refers to any subject (e.g., a person, organization, thing, data model, abstract entity, etc.) as determined by the controller of the DID.
In simple words, decentralised identifiers are cryptographically-verifiable identifiers which are stored on a decentralised ledger, which enables users to own and manage their digital identity.
