Prove your work is yours

iPhone

Prove your work is yours, from this moment on. Photon gives any file a permanent, independently verifiable timestamp. Take a photo or pick a file, tap Stamp, and Photon creates proof that this exact file existed right now. Proof anyone can check, forever. No crypto wallet. No jargon. Your files stay private. • Stamp: photograph something on the spot, or pick a photo or document. Photon fingerprints the file on your device and timestamps it. • Verify: check any file for a proof, no account needed. Hashing happens on your phone; the file never leaves it. • Share proof: hand anyone a link or QR code so they can verify independently. • Keep your work: every capture is stored safely in your Photon files, ready to download or share whenever you need it. • Own your evidence: download portable .ots receipts that verify independently of Photon. Made for photographers protecting their shots, creators and inventors establishing precedence, students and professionals proving submission dates, and anyone documenting what they saw, when they saw it. How it works: Photon computes your file's SHA-256 fingerprint and anchors it via the OpenTimestamps standard to a public blockchain, creating an unforgeable, independently checkable record. Your file itself is never made public. Free to use. Your files, your proofs, yours to export or delete at any time.

Add your proof to Apple Wallet. One tap on any confirmed file gives you a pass with a QR code anyone can scan to verify your work. Small fixes and improvements.
