Prove a video was filmed live.
Two phones, signed QR codes and a blockchain-anchored proof: anyone can check the video was not fabricated afterwards.
How it works
1. Phone A displays a signed QR code
The QR keeps changing and cannot be predicted in advance.
2. Phone B films
Each video segment conditions the next QR: the order cannot be faked.
3. The proof is signed, analysed and anchored
The result is sealed and anchored on a blockchain, verifiable by anyone.
Use cases

What the proof guarantees — and what it does not
It guarantees the video was captured live, in order, with its context (location, sensors) recorded.
It does not guarantee the filmed scene is genuine: a scene staged in front of the camera remains possible.
