Beaver Proof Verifier

Verify digital proof packages directly on your iPhone or iPad. Beaver Proof Verifier checks whether files contained in a Beaver Proof package are still exactly as they were when the proof was created. It also validates the included OpenTimestamps proof and shows whether the timestamp has been anchored in the Bitcoin blockchain. OPEN AND VERIFY Select a proof package from the Files app or open it through the iOS Share Sheet. Beaver Proof Verifier extracts the package, checks its contents and presents the verification result clearly. VERIFY FILE INTEGRITY The app recalculates the digital fingerprint of the protected files and compares it with the original proof. Even the smallest later modification causes the verification to fail. CHECK INDEPENDENT TIMESTAMPS OpenTimestamps proofs can demonstrate that a digital fingerprint existed no later than the confirmed blockchain timestamp.…
