How Fairness Works
In PvP mode, both players' wagers are locked in a vault smart contract on Algorand. The coin flip result is determined by an on-chain commitment-reveal scheme — the outcome is committed before either player can influence it. After the flip, the commitment is revealed and can be independently verified. Neither AlgoRoll nor any player can manipulate the result.
