JOSE JSON Web Proof (JWP) — draft-ietf-jose-json-web-proof#

IETF 123 (Madrid) digest Program Wildcard pick Madrid · 19–25 July 2025

Draft Slides Session recording Materials

  • Tier: Wildcard
  • Why: A new container format alongside JWS/JWE built specifically for multi-message, zero-knowledge-style proofs (e.g. BBS) — i.e. selective disclosure and unlinkable presentations as a first-class primitive rather than a bolt-on. If privacy-preserving credentials go mainstream, this is plumbing you'll encounter.
  • What: JSON Web Proof, plus its algorithms and token format, defining a JWS/JWE-sibling structure for proofs over multiple messages. (from abstract only)
  • How: Unlike JWS (sign one payload), JWP is designed around several individually-disclosable messages and proof algorithms that support selective disclosure / ZK properties.
  • Where applicable: General, forward-looking; verifiable-credential and privacy-preserving-identity ecosystems. Early relative to SD-JWT, but architecturally more ambitious.
