How Provably Fair SHA-256 Hashing Guarantees Unmanipulable Crash Rounds
An explanation of server seeds, client seeds, nonces, and mathematical SHA-256 formulas that ensure every flight multiplier is 100% random.
Provably Fair technology guarantees that neither the platform operator nor players can predict or alter round flight outcomes. Every round result is pre-determined cryptographically using SHA-256 seed hashing.
1. Server Seed, Client Seed, and Nonce
Before bets are accepted, the server generates a secret Server Seed and publishes its SHA-256 hash. The client seed is generated from player inputs, and the nonce increments with every round.
2. The Multiplier Hash Formula
The exact crash point is calculated using HMAC-SHA256 signature conversion into a floating-point multiplier value.
// Cryptographic Crash Point Formula
const hash = crypto.createHmac('sha256', serverSeed).update(clientSeed + ':' + nonce).digest('hex');
const subHash = parseInt(hash.substring(0, 13), 16);
const crashPoint = (Math.pow(2, 52) * 0.97) / (Math.pow(2, 52) - subHash);Key Takeaway
Players can independently audit any round result by entering the revealed Server Seed into third-party SHA-256 calculators.
