Scenario: Drone Flight Decision

A drone autonomy stack flagged a potential airspace conflict at 1,200ft. This is what the decision receipt looks like, and what you can prove with it.

What This Receipt Proves

Tamper-Proof

The dual-hash means any modification to this event, even a single character, produces a completely different hash. The original is preserved.

Chain Position

Your receipt is at position #N in a Merkle chain. Every receipt before and after it is cryptographically linked. You cannot insert, delete, or reorder.

Court-Admissible

Cryptographic receipts meet FRE 901(b)(9), the federal standard for machine-generated evidence. This receipt can be introduced in any US federal proceeding.
