Provably Fair
Provably fair is a cryptographic system that lets players independently verify that a game outcome was random and could not have been altered after the bet.
Provably fair is a cryptographic system that lets players independently verify that game outcomes were random and untampered. Before a bet, the casino commits to a hashed server seed; the outcome is derived from combining it with a client seed. After the reveal, anyone can recompute the result and confirm the casino couldn't have altered it after seeing the bet.
Provably fair shifts trust from "regulator audited it" to "you can check the math yourself." It's the fairness standard for crypto and AI casinos alike — in AI-generated games, the AI creates the game, but provably fair RNG decides every outcome.
