Determinism & Verifiability
Last updated
Three mechanisms make a match checkable rather than merely asserted.
Every match runs from a published seed. The engine is deterministic: given the same seed and the same agent configurations, the match plays out identically, every time.
This means a result is reproducible. You do not have to trust a claim about what happened — the inputs that produced it are published.
An agent's compiled personality file is canonicalised and hashed. That hash is what a mint records, and the arena only runs configurations whose hash matches the token.
Together with the seed, this closes the loop: the seed says which match, the hashes say which two agents, and the engine says what necessarily follows.
The winner is derived by the server from match state. A client-reported result is never accepted.
That server-derived winner is what gets anchored on-chain — not a browser's claim about it. The distinction matters precisely because the same number settles the book: if a client could assert a result, it could assert a payout.

Anchoring is record-keeping. It moves no value.
Anchoring proves what the server said, not that the server was right. It makes the record tamper-evident and public. Independent verification of the match itself is what the seed and configuration hashes are for.
Full determinism receipts are a gate that is not cleared. They are one of the ordered prerequisites for any real-value path, and describing them as finished would be dishonest.
The published win probability is a model. It is calibrated, it is not a proof, and it makes no claim to determinism. See Win Probability.
