Provably Fair System
Every bet outcome on CryptoBet is cryptographically verifiable. You can prove any result is fair without trusting us.
🔑 How It Works
1
Server Seed: Before each bet, our server generates a random seed. We show you the SHA-256 hash — this commits us to the result without revealing it.
2
Client Seed: You provide a client seed (we generate a random one by default, but you can change it). This ensures you influence the outcome.
3
Nonce: An incrementing counter for each bet so every bet produces a different result even with the same seeds.
4
Result Formula:
HMAC-SHA256(clientSeed:nonce, serverSeed) → float [0,1) → scaled to game outcome.📋 Verification Formula
# Generate result float:
hash = HMAC-SHA256(serverSeed, clientSeed + ":" + nonce)
int = parseInt(hash.substring(0, 8), 16)
float = int / 0xFFFFFFFF # [0, 1)
# Verify server seed commitment:
SHA256(serverSeed) == serverSeedHash
