Formal name
W3C VCDM v2.0 - Verifiable Credentials Data Model, W3C Recommendation, 15 May 2025, Manu Sporny et al
Overview
A verifiable credential is a specific way to express a set of claims made by an issuer, such as a driver's license or an education certificate. This specification describes the extensible data model for verifiable credentials, how they can be secured from tampering, and a three-party ecosystem for the exchange of these credentials that is composed of issuers, holders and verifiers.
This document also covers a variety of security, privacy, internationalization, and accessibility considerations for ecosystems that use the technologies described in this specification.
Note
Verifiable Credentials Overview
VCDM is part of a larger family of specifications, which are meant to work together. An overview of the family of specification is available here
Note
W3C Recommendations have been formally reviewed by W3C Members, by software developers, and by W3C groups and interested parties. W3C recommends the wide deployment of a Recommendation as a standard for the Web. These documents MAY be cited as W3C standards.
