Prove that a photo, video or document existed on a given day and has not changed since. Your file never leaves your device: only its SHA-256 fingerprint is timestamped via OpenTimestamps and anchored in Bitcoin. 3 files a month free; checking is always free.
Hi everyone, I'm Gökhan, a civil engineer and court-appointed expert witness in Türkiye. In building, rent and damage cases I keep seeing the same problem: someone has the right photo, but nobody can show it was taken before the dispute started.
File Proof is my answer. The file stays on your phone; only its fingerprint is timestamped in Bitcoin through OpenTimestamps. You keep a small .ots proof file, and anyone (a judge, a lawyer, the other party) can check it for free, on our site or independently on opentimestamps.org.
3 files a month are free. A PDF proof report with a QR code is $4 for those who need a ready document.
Honest limits: it proves the file existed then and is unchanged; it does not prove who took it or where, and it is not a notarisation.
I'd love to hear where you would use it and what would make the PDF report more useful in your country.
