## What is 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. Verification does not depend on Beaver Proof or a proprietary account.

SUPPORTED PROOFS

• Beaver Page Proof packages
• Beaver File Proof packages
• Beaver Photo Proof packages
• OpenTimestamps .ots proofs

BUILT FOR SIMPLE, INDEPENDENT VERIFICATION

• No account required
• No subscription
• Clear verification results
• Works with files stored locally or in iCloud Drive
• Free to use

Beaver Proof Verifier does not determine whether the original content was true or legally valid. It verifies file integrity and the independently anchored timestamp.
