House rules · enforced by the chain, not the house
Nobody can cheat.
Not even us.
01
Commit before kickoff
Every duel — both stakes, both beliefs, the exact question — is written to Solana before the match starts. The program rejects late entries by the chain's own clock. Hindsight picks are impossible by construction.
02
The proof settles
Settlement is a CPI into TxLINE's on-chain validate_stat — a 3-stage Merkle proof of the real match statistic, verified against the daily root TxLINE publishes. A fake result simply fails to verify.
03
Append-only history
The program has no instruction to amend or delete a duel. Losses can't be buried, records can't be polished. The scoreboard is exactly what happened.
