Check a credential

Paste a share link, a credential reference or its hash. You get an answer in seconds, straight from the blockchain.

We work out which one you pasted. Spaces and line breaks are fine.

Every check answers three questions

01 · IntegrityIs it exactly what was issued, down to the last character?
02 · AuthenticityDid the institution sign it with its own key?
03 · ProvenanceIs that key really theirs, as registered on chain?

Free and anonymous. The graduate is told their credential was checked, never who checked it.
