UN/CEFACT UNTP

The UN Transparency Protocol defines how product passports, conformity credentials, and traceability events travel as W3C Verifiable Credentials. dVeracity now implements the v0.7.0 conformance model: verification sessions produce UNTP ConformityAssessment records and issue Digital Conformity Credentials anchored to vLEI identity.

UNECE / UN/CEFACT

In Developmentv0.7.0 implemented; v1.0 targeted

UNTP is the strongest strategic fit in the family and is now active in dVE: the platform operates as a verifier and attestation issuer with vLEI-anchored identity, produces UNTP ConformityAssessments during verification, and issues Digital Conformity Credentials. UNTP standardizes exactly that role for the EU DPP era.

Key Facts

Implemented version

v0.7.0 (in dVE, Aug 2026)

v1.0 target

1 September 2026

Credential format

W3C VC Data Model 2.0, JOSE proofs

Assurance model

Graded NC assurance + assuranceLevel on credentials

Implemented Components

dVE already issues and resolves UNTP-aligned credentials; the remaining work is v1.0 finalization and ecosystem interoperability.

Digital Conformity Credential

Implemented

dVeracity issues Digital Conformity Credentials via VCIssuanceService, embedding UNTP ConformityAssessment objects and an assuranceLevel derived from graded non-conformance assurance.

UNTP Assessment Storage

Implemented

Verification results are stored as structured UNTP assessments in dve_non_conformances.untp_assessment (JSONB), linked to review dashboards and credentials.

Resolvable Evidence Links

Implemented

UNTP evidence is exposed through resolvable public links: session IDs, MAV documents, and the /evidence viewer work across tenant workspaces.

Digital Product Passport

The product-level credential carrying sustainability claims, composition, and lifecycle data. DPP issuance is on the roadmap pending v1.0 finalization.

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.

Integration Flow

OFP + PCF Data

dVE Verification

UNTP ConformityAssessment

Digital Conformity Credential

EU Digital Product Passport

Verified emissions claims become UNTP ConformityAssessments and Digital Conformity Credentials feeding EU Digital Product Passports.
