Introduction

This document contains a list of all known Decentralized Identifier Methods and their associated specifications.

The Registration Process

Software implementers may find that the existing Decentralized Identifier Methods listed in this repository are not suitable for their use case and may need to add a new method to this registry. Adding a Decentralized Identifier Method to this list is designed to be a lightweight, community-driven process. In order to add a new method to this registry, an implementer MUST:

1. Implement at least an experimental version of the new DID Method.
2. Create a specification describing the new DID Method that is publicly available and intended to be conformant with the DID specification at https://w3c-ccg.github.io/did-spec/.
3. Request that the specification be added to this registry by submitting a Github Pull Request that adds the new method to the list of existing methods, with URL.

Specifications that do not meet these criteria will not be accepted. Old listings which fall out of conformance may be removed.

Implementers that would like help or guidance during this process are urged to join the W3C Credentials Community Group and request assistance via the mailing list.

This table summarizes the DID method specifications currently in development. The links will be updated as subsequent Implementer’s Drafts are produced.
