This document serves as a collection of known DID Methods.
The registration process is described in the Decentralized Identifier Extensions.
As well as sections marked as non-normative, all authoring guidelines, diagrams, examples, and notes in this specification are non-normative. Everything else in this specification is normative.
This table summarizes the DID method specifications currently in development. The links will be updated as subsequent Implementer’s Drafts are produced. This registry does not act as an endorsement of any particular DID method or its underlying technologies by the W3C, the W3C Decentralized Identifier Working Group, or any affiliated members of the W3C. It exists as a mechanism for developers to discover various DID methods that they might wish to implement.
The normative requirements for DID method specifications can be found in Decentralized Identifiers v1.0: Methods [DID-CORE]. DID methods that do not meet these requirements will not be accepted. We encourage DID method authors to provide an email address in the Author Links column, as this helps with maintenance. If an email address is omitted, a label noting that there is no contact information for the author will be applied to the registry entry.
