The Decentralised Identity standards that will be used in the DARP protocol and by Decentralised Address Name Registrars are Decentralised Identifiers (DIDs) and Verifiable Credentials. A DID is a URI (e.g. did:example:123456789abcdefghi) that is unique to an entity (person, organisation) wanting to store identity information. A DID resolves to a DID Document that is stored on a blockchain and is cryptographically signed by the owner. An example of a DID Document is as follows:
{"@context": "https://www.w3.org/ns/did/v1","id": "did:example:123456789abcdefghi","authentication": [{"id": "did:example:123456789abcdefghi#keys-1","type": "Ed25519VerificationKey2018","controller": "did:example:123456789abcdefghi","publicKeyBase58": "H3C2AVvLMv6gmMNam3uVAjZpfkcJCwDwnZn6z3wXmqPV"}],"service": [{"id":"did:example:123456789abcdefghi#ard","type": "AddressResolverDocument","serviceEndpoint": "https://example.com/myaddress/","ardHash": "sha512-3bb12eda3c298db5de25597f54d924f2e17e78a26ad8953ed8218ee682f0bbbe9021e2f3009d152c911bf1f25ec683a902714166767afbd8e5bd0fb0124ecb8a"}]}
