🛡️ How Provably Fair works

Commit. Before betting opens we generate a secret 256-bit server seed and publish only its SHA-256 hash. The outcome is locked in — we cannot change it once you have seen the hash.
Player input. When betting closes, the round's client seed is composed from the personal seeds of the first bettors — an input the house does not control. The round number is the public nonce.
Outcome. The crash point is derived as HMAC-SHA256(server_seed, client_seed:nonce) → first 52 bits → uniform number U ∈ [0,1) → crash = max(1, (1 − house_edge) / (1 − U)).
Reveal. After the crash the raw server seed is published. Hash it yourself to confirm the commitment, then recompute the multiplier below.
