Issue every organic and fair-trade certificate as a verifiable credential on a shared registry. The DID and VC Ledger and Provenance Notary bind each certificate to its issuer and its produce batch, so anyone reads authenticity through a public verification layer.
Turn a certificate that only its issuer can confirm into a credential anyone can verify instantly.
01.
Replace scanned PDFs with signed credentials. Each organic or fair-trade certificate is issued as a W3C verifiable credential, cryptographically bound to the certifier that signed it.
02.
Anchor every certifier's identity. The DID and VC Ledger holds a decentralised identifier for each accredited body, so a credential resolves to a real, recognised issuer and nothing else.
03.
Tie the certificate to the goods. Provenance Notary binds each credential to a specific produce batch and its holder, so an organic claim cannot be reused on an unrelated lot.
04.
Kill a compromised certificate on-chain. When accreditation lapses or fraud surfaces, the issuer revokes the credential and every verifier sees the change on the next scan.
05.
Open verification to everyone. A retailer, customs officer, or shopper resolves a QR code against the registry and confirms validity without ever contacting the certifier.
06.
Make forgery return nothing. A fabricated certificate carries no matching on-chain record, so verification fails immediately instead of passing a convincing-looking scan.
Follow a fair-trade certificate from an accredited certifier issuing it to a customs officer verifying it at the border.

Cerulea splits certification into modular contracts for issuer identity, credential binding, revocation, and open verification, so no single party can forge or silently withdraw a certificate.
Shared certification is a horizontal capability. Here is how certifiers, retailers, and regulators use one open registry.
Issue organic and fair-trade credentials that anyone can verify without staffing a phone line, and revoke a compromised certificate the instant fraud is detected.
Key Asset Types
Confirm every supplier certificate in seconds before a purchase order, turning verified organic and fair-trade status into a defensible claim on the shelf.
Key Asset Types
Verify certificates at the border directly against the registry, rejecting forged documents automatically instead of chasing issuers for confirmation.
Key Asset Types
Whether a large certifier is bridging its accreditation database or a smallholder cooperative is issuing from a phone, Cerulea routes both into one verifiable registry.
For accredited bodies with legacy certificate databases. Existing issuance events are translated into signed verifiable credentials through the API gateway automatically.

Public Verification Layer
Building a verifiable credential registry with issuer identity, batch binding, revocation, and a public verification API from scratch requires identity engineers and long certifier onboarding cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects decentralised identity integration benchmarks. Standing up a DID method, writing credential issuance and revocation logic, and shipping a public verification API for an average program takes a baseline of 7 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your issuance and revocation rules into pre-audited WebAssembly binaries and provisions the shared registry and verification layer instantly.
