First Public Working Draft: Verifiable Credential Forgery Defense v1.0

The Verifiable Credentials Working Group has published a First Public Working Draft today for the Verifiable Credential Forgery Defense v1.0 specification. This publication is complementary to the publication of quantum-resistant cryptosuites and is motivated by the same threat. While cryptosuites let issuers secure new proofs with post-quantum signatures, this specification lets an issuer establish post-quantum-backed authenticity for credentials that may have been signed with conventional quantum-vulnerable algorithms and cannot, or is not feasible, to re-issue them. This is achieved by publishing a witness list that is itself the subject of a separate Verifiable Credential that can be signed with a quantum-resistant scheme.

The Working Group welcomes comments via the GitHub repository issues.
