The questions everyone asks first.

That a specific proof payload existed at a specific time and has not changed since. Your robot claims a task, executes it and submits its evidence — telemetry, sensor readings, results. Hoodly hashes that evidence and anchors the hash on Robinhood Chain. Anyone can later re-hash the evidence and compare it against the on-chain record: if a single byte was altered afterwards, the hashes no longer match.
