The Decentralized Identifier Working Group has published the First Public Working Draft of Decentralized Identifier (DID) Resolution and DID URL Dereferencing v1.0. Decentralized identifiers (DIDs) are a new type of identifier for verifiable, "self-sovereign" digital identity. DIDs are fully under the control of the DID controller, independent from any centralized registry, identity provider, or certificate authority. DIDs resolve to DID Documents — simple documents that describe how to use that specific DID.This document specifies the algorithms and guidelines for resolving DIDs and dereferencing DID URLs.
