Publish every Marine Stewardship Council certificate as a verifiable credential on a public registry. The DID and VC Ledger and Provenance Notary bind each certificate to its holder and catch, and a public API answers any verification request in real time.
Turn a certificate that takes weeks to confirm into a credential a retailer verifies in one query.
01.
Publish certificates openly. Every Marine Stewardship Council certificate is issued as a verifiable credential to a public registry, so anyone can confirm it without contacting the council.
02.
Tie the label to real product. Provenance Notary binds each certificate to its holder and the specific catch, so the blue label cannot be lifted onto a non-certified product.
03.
Answer verification at scale. A public API resolves any certificate instantly, letting a retailer verify hundreds of supplier certificates in an afternoon instead of weeks of email.
04.
Make copies fail. A forged or copied certificate carries no matching on-chain record, so verification returns nothing rather than passing a convincing-looking document.
05.
Anchor the council's authority. The DID and VC Ledger records the certifying body's identity, so every credential resolves to a recognised issuer and not an impostor.
06.
Connect certificate to supply chain. Each credential links to the catch and custody record, so verification confirms not just the paper but the product behind it.
Follow a sustainability certificate from council issuance to a retailer verifying hundreds in a single session.

Cerulea decomposes certificate verification into modular contracts for issuer identity, credential binding, public resolution, and forgery rejection, so the blue label stays trustworthy.
Sustainability certificate verification is a horizontal capability. Here is how councils, retailers, and consumers put one registry to work.
Issue certificates that anyone can verify instantly and expose copies automatically, protecting the integrity of the blue label without staffing verification calls.
Key Asset Types
Verify hundreds of supplier certificates in an afternoon through the API, turning a weeks-long email process into a single defensible check.
Key Asset Types
Confirm a product's sustainability claim directly against the registry, trusting cryptographic proof rather than an unverifiable printed label.
Key Asset Types
Whether a council is bridging its certificate database or a retailer is querying the public API, Cerulea routes both into one verifiable registry.
For certifying bodies with legacy certificate databases. Existing issuance records are translated into verifiable credentials through the API gateway automatically.

Public Verification Layer
Building a public credential registry with issuer accreditation, catch binding, a verification API, and forgery rejection from scratch requires identity engineers and long council onboarding. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects decentralised identity integration benchmarks. Standing up a DID method, credential issuance, a public verification API, and forgery rejection 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 credential and verification rules into pre-audited WebAssembly binaries and provisions the public registry and API layer instantly.
