UN/CEFACT UNTP
The UN Transparency Protocol defines how product passports, conformity credentials, and traceability events travel as W3C Verifiable Credentials. It is the emerging bridge between supply-chain data and the EU's Digital Product Passport regime — and it maps almost one-to-one onto dVeracity's attestation architecture.
UNECE / UN/CEFACT
Roadmapv0.7.0 → v1.0 (Sep 2026)UNTP is the strongest strategic fit in the family: dVeracity already operates as a verifier and attestation issuer with vLEI-anchored identity. UNTP standardizes exactly that role for the EU DPP era — conformity credentials it defines are the product dVeracity ships.
Key Facts
Protocol Components
UNTP is a family of credential types and resolution services that gets released together as v1.0.
Digital Product Passport
The product-level credential carrying sustainability claims, composition, and lifecycle data.
Digital Conformity Credential
Third-party conformity assessments as verifiable credentials — the exact artifact dVeracity issues as an independent verifier.
Digital Traceability Events
Make, move, and modify events derived from EPCIS, wrapped as credentials for cross-border trust.
Digital Identity Anchor + Identity Resolver
Links credentials to authoritative registers (like LEI/vLEI) and resolves product identifiers to their credential graphs.
Verifiable Credentials Profile
Pins the stack: VC Data Model 2.0, enveloping JOSE proofs, Bitstring Status List revocation, did:web and did:webvh.
Integration Flow
Verified emissions claims become UNTP conformity credentials feeding EU Digital Product Passports.
