Read the full description
ProofLens bakes proof into a photo at the moment you take it: a local SHA-256 fingerprint, an RFC 3161 trusted timestamp from an independent authority, and a Bitcoin anchor via OpenTimestamps that anyone can verify later. Burn date, time, GPS, altitude and notes into the image with configurable watermark templates, keep every proof in an evidence library, and verify any ProofLens file fully on device. Photos never leave your phone; only the hash is sent for timestamping.
