Origin, craftsmanship, quality assessment and cultural heritage — all sealed by cryptographic signatures and written into an evidence chain. One item, one code: scan to verify, results are instant and tamper-proof.
Built on DPP-CQ Standard (ICO Std 2001) · White Paper
Every product has its own passport page and a globally unique identifier. The items below are pulled live from issuance records — no manual curation.
Append-only and interlinked — any retrospective change breaks the chain.
A third-party RFC 3161 timestamp fixes an absolute time that even the issuer cannot backdate or re-sign.
Dynamic NFC secure-chip codes — one chip per item, unclonable, aligned with EN 18220 L2.
One engine covering the full lifecycle: issuance, carriers, verification and governance.
Ed25519 asymmetric signatures: every credential is signed by the issuer’s private key, with the public key published in a DID document so anyone can verify independently.
L1 open QR codes for instant verification; L2 secure NFC chips — one per item, clone- and transfer-resistant, aligned with the EN 18220 tiers.
Credential hashes are append-only links in an evidence chain; the whole chain can be recomputed and checked, leaving nowhere to hide a change.
Structure, signature, validity, issuer, revocation and evidence chain — checked layer by layer, fully logged, with unforgeable results.
Following W3C and ISO international standards, credentials are not tied to a single platform and can be parsed and verified across compliant systems worldwide.
Institutions, credentials, verification logs and the evidence chain are governed in one place, with revocation and full-chain checks — private keys never exposed.
From independent assessment to the consumer’s scan — four steps form a trusted loop.
Origin, craftsmanship and quality are assessed independently; heritage grades and master-artisan details are registered truthfully.
The assessment is signed by the issuer, producing a verifiable credential written into the hash evidence chain.
The credential is bound one-to-one to the QR code / NFC chip on the packaging — one item, one code, unclonable.
Consumers scan to open the passport page; the six-point verification runs locally and the genuine article is confirmed instantly.
No proprietary lock-in — built on globally recognised open standards.
