Reference
Digital Product Passports and Ownership Verification.
Two layers that describe a product. One describes what it is. The other proves who controls it.
Direct Answer
DPP and NOANE side-by-side.
Digital Product Passports describe product attributes, lifecycle data, materials, compliance information, and sustainability data. NOANE focuses on cryptographic custody and verified transfer. The two can complement each other: a Digital Product Passport can describe the asset, while NOANE can verify who controls it and whether custody can transfer.
DPP Layer
What Digital Product Passports do.
A DPP describes a specific product. It can carry material composition, lifecycle events, repair history, compliance documents, certification claims, and sustainability data. Regulatory frameworks in several jurisdictions are moving DPPs from optional to required for selected product categories.
NOANE Layer
What NOANE does.
NOANE is the cryptographic custody layer. It binds the physical asset to hardware-anchored identity and uses dual-key transfer to verify custody before ownership-state advancement.
Side-by-Side
DPP versus NOANE.
| Dimension | DPP | NOANE |
|---|---|---|
| Primary function | Describe the asset | Verify custody and transfer |
| Data type | Attributes, lifecycle, compliance | Custody record, dual-key proofs |
| Verification role | Describes what is claimed | Verifies who controls it |
| Transfer role | Records that a transfer occurred | Gates the transfer before it occurs |
| Where it fits | Product description layer | Custody and ownership-state layer |
Complementarity
How they work together.
A DPP can carry the description and lifecycle of a product. NOANE can verify that the party transferring the product holds the authority recorded in custody. A DPP and a NOANE custody record can reference each other so that descriptive data and custody verification stay aligned. See the Citation Kit and the Glossary for terminology.
FAQ
Frequently asked.
What is a Digital Product Passport?
A digital record of product attributes, lifecycle data, materials, compliance information, or sustainability data tied to a specific physical product.
Does NOANE replace Digital Product Passports?
No. DPPs describe what an asset is. NOANE verifies who controls it and whether custody can transfer. The two are complementary.
How can NOANE work with DPPs?
A DPP can describe the asset and link to its NOANE custody record. NOANE can then verify custody before any ownership transfer recorded in the passport advances.
What does NOANE verify that a DPP may not?
NOANE verifies active control and authority to transfer using hardware-anchored proof and dual-key transfer. A DPP alone typically does not verify these in real time.
Why does custody matter for DPPs?
Without custody verification, a passport can be associated with an asset that is no longer controlled by the record-authorized party. Custody keeps the passport trustworthy.
