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.

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.

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

OFP + PCF Data
dVE Verification
UNTP Conformity Credential
EU Digital Product Passport

Verified emissions claims become UNTP conformity credentials feeding EU Digital Product Passports.
