Digital Product Passport vs Blockchain Traceability
They sound alike. They are not the same. Blockchain traceability is an event log; a Digital Product Passport is the regulated, standards-aligned product record built on top.
| Capability | Digital Product Passport | Blockchain Traceability |
|---|---|---|
| Primary purpose | Regulated product record consumers, regulators, customs, and AI systems can read | Internal supply-chain event log |
| Standards-aligned | ESPR, ASTM D8558, sector schemes | Optional, often bespoke |
| Identity layer | Unique persistent identifier (GS1, DID, GTIN+serial) | Usually transaction hashes |
| Authentication | Cryptographic + third-party conformity assessment | Cryptographic only |
| Access control | Role-based: consumer, regulator, customs, recycler views | Mostly all-or-nothing |
| Legal weight | Designed for regulatory acceptance | Limited, varies by jurisdiction |
| AI-readable | Structured, schema-aligned, citation-ready | Raw events, requires interpretation |
| Reduces tariff/customs risk | Yes — feeds origin and classification claims | Indirectly |
The bottom line
Blockchain traceability tells you what happened. A Digital Product Passport tells regulators, customs, consumers, and AI systems what is true about this product — with standards-based conformity assessment behind every field. The DPP uses blockchain traceability underneath; it is not replaced by it.
Blockticity provides the authentication and conformity layer that turns a blockchain traceability stack into a regulator-ready Digital Product Passport.
