DID

Decentralized identifiers (DIDs) are a type of globally unique identifier (GUID, UUID) that enables an entity to be identified in a manner that is verifiable, persistent (as long as the DID controller desires), and does not require the use of a centralized registry.[1] DIDs enable a new model of decentralized digital identity that is often referred to as self-sovereign identity or decentralized identity.[2] They are an important component of decentralized web applications. https://en.wikipedia.org/wiki/Decentralized_identifier
