Block-level tamper detection — any bit flip is visible.
Seal hashes at the block level, so tampering isn't binary — it's a map. Crop a photo, splice a video, swap a token in a model, and the receipt shows exactly which region changed.

Even a single edited frame leaves a fingerprint. The original hash doesn't match, and the diff map points straight at the splice. That's the difference between 'looks fake' and 'here's the frame.'
