What this proves — in plain English
This decision happened.

Recorded on Base Sepolia at April 30, 2026 at 5:39 PM KST. The transaction is permanent and publicly visible — try editing it.

These were the inputs.

Every prompt, every retrieved context, every alternative the AI considered — fingerprinted into the same Merkle tree. Change one byte and the entire root invalidates.

This was the chosen output.

Not just what shipped — what was rejected, scored, and overridden. A future investigator can see the full reasoning, not just the final answer.

A neutral third party witnessed it.

trace.ai anchored the root from a separate wallet than the operator who signed the payload. Neither party can produce this evidence alone.

Run a simulation

Watch a decision earn its receipt — across 7 industries.

Pick a scenario. Press play. Each step shows a different artifact — the ticket, the score bars, the signature, the Merkle tree, the block, the verifiers — so you see the proof being built. Same protocol works for e-commerce, finance, healthcare, HR, insurance, and legal.
