Verify a document
Check whether a document's fingerprint was recorded on the blockchain. If you choose files, they are fingerprinted in this browser and never uploaded.
Nothing checked yet
Enter a fingerprint or choose files, then select Check.
A result is final only after enough blocks have been added on top of the record. A pending record can still disappear; check again later.
-
Private
Your files are fingerprinted on this device. Only the 64-character fingerprint is checked.
-
Independent
The fingerprint is checked against a public blockchain record, not against a copy we keep.
-
Final
A record counts as final once enough blocks are built on top of it. Until then it shows as pending.
