How Provable Fairness Works
Neither side can manipulate the outcome — here is why
Server Seed Hash
Before your bet, the server commits to a random seed by showing you its SHA-256 hash. The server can't change the seed later because you've already seen the hash.
Your Client Seed
You provide a client seed (or use a random one). This ensures you contribute to the randomness — the server can't know the outcome in advance because it doesn't control your seed.
Roll Deterministically
HMAC-SHA256(serverSeed, clientSeed:nonce) generates a verifiable float from 0.00 to 100.00 that anyone can reproduce.
Server Seed Revealed
After the bet, the server reveals the original seed. Hash it yourself — it must match the hash shown before the bet.
Verify Independently
Paste the revealed seed, your client seed, and the nonce here. The same algorithm reproduces the exact roll, proving the outcome was fair.
