How physical truth becomes cryptographic fact.
The Keryx Protocol is an open standard for binding a physical object to a permanent, unforgeable digital record — readable by any NFC-capable phone, verified without a server.
Three tiers. One protocol.
Standard
Register a work via the web app. Receive a pre-paired chip. Embed at home.
- Web-based registration
- Pre-paired secure chip
- Permanent public record
Studio
Bulk chip orders. Atelier-branded verification experience. Team dashboard.
- Bulk chip provisioning
- Custom verification page
- Team access controls
Enterprise
Factory-line embedding. API integration with existing PLM/ERP systems. Compliance reporting.
- Factory-line provisioning
- PLM/ERP API integration
- EU DPP compliance reports
Three layers. Fully independent.
Hardware Layer
A secure element chip embedded in the physical object. Generates a unique cryptographic signature on every tap — uncloneable by design.
Protocol Layer
An open verification protocol. The chip signature is verified client-side against the public record — no Keryx server required for verification.
Record Layer
An immutable provenance record anchored to a permanent, decentralised store. Every ownership event, exhibition, and restoration is appended automatically.
One object. One record. Infinite history.
Anchor
The root identity token. Created at registration. Bound to the chip. Cannot be transferred without physical chip present.
Digital Twin
A full digital record of the object — materials, provenance, maker story, ownership history. Updates automatically as events are logged.
Child Tokens
Created for each significant event — a sale, an exhibition, a restoration. Each carries a timestamp, the relevant parties, and a link back to the Anchor.
