UNTP Digital Product Passport

UNTP — the UN Transparency Protocol — is targeting a 1.0 Digital Product Passport specification release on 1 September 2026, built on the same W3C Verifiable Credentials Data Model 2.0 this protocol’s records already use.

Why AuthiChain

• UNTP issues every credential, including its Digital Product Passport, as a W3C VC 2.0 object — the identical base data model documented in SPEC.md §2, not a competing format
• UNTP is UN/CEFACT and UNECE work, currently on 0.6.x pilot releases; SPEC.md is a v0.1.0 draft — both are pre-1.0 specs published for implementers to compare, not finished standards
• The 28-fixture conformance suite and reference verifier are public, so the gap between a ProvenanceRecord and a UNTP DigitalProductPassport credential is something an implementer can check directly, not take on faith

How it works

Issue a unique identifier per unit, anchor its record on-chain for tamper-evidence, and let anyone verify it with a single scan. Plans start at $49/mo.

FAQ

Is a record issued under this protocol a valid UNTP DigitalProductPassport credential?

Not directly — UNTP defines its own credential type and JSON-LD context on top of VC 2.0. This protocol’s ProvenanceRecord shares the base standard but is a different schema; mapping between them is inspectable, not assumed.

When does UNTP 1.0 ship?

The UNTP team is targeting a 1.0 release on 1 September 2026; current releases are versioned 0.6.x and marked suitable for pilot implementations.
