Portions of the work on this specification have been funded by the United States Department of Homeland Security's Science and Technology Directorate under contracts HSHQDC-16-R00012-H-SB2016-1-002, 70RSAT20T00000010, and HSHQDC-17-C-00019. The content of this specification does not necessarily reflect the position or the policy of the U.S. Government and no official endorsement should be inferred.

Work on this registry has also been supported by the Rebooting the Web of Trust community facilitated by Christopher Allen, Shannon Appelcline, Kiara Robles, Brian Weller, Betty Dhamers, Kaliya Young, Kim Hamilton Duffy, Manu Sporny, Drummond Reed, Joe Andrieu, and Heather Vescent, Dmitri Zagidulin, and Dan Burnett.

This document was published by the Decentralized Identifier Working Group as a Group Note using the Note track.

This Group Note is endorsed by the Decentralized Identifier Working Group, but is not endorsed by W3C itself nor its Members.

This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress.

1. Introduction

This section is non-normative.

This document serves as a collection of known DID Methods.

1.1 The Registration Process

The registration process is described in the Decentralized Identifier Extensions.

1.2 Conformance

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.

2. DID Methods

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.
