W3C Verifiable Credentials

Check a diploma or credential in seconds

Use the ID or QR code on the certificate, or check the PDF itself.

For digital wallets and developers. The token is checked in your browser.

Why you can trust the result

Built to make forgery fail

Digital signatures, published issuer keys and a public revocation registry — checked on every verification.

Tamper-evident credentials

Every credential is signed with the issuing institution's key, and its fingerprint is registered at issuance. Editing, backdating or forging it makes verification fail.

Verify a document

Signed by the institution itself

Only the institution's own staff can issue, and every issuance is audited. Its public keys are published at its did:web address, so the source is checked directly.

Staff sign in

Open standards, no holder data

Credentials follow W3C Verifiable Credentials 2.0 and Open Badges 3.0. The registry stores no personal data — the holder's name lives only in the signed document.
