How Provably Fair Works
Provably fair systems give you cryptographic proof that an operator didn't tamper with the result of a game.
The mechanism
- The server generates a server seed and publishes its hash.
- You provide a client seed of your own.
- The game uses
HMAC(serverSeed, clientSeed + nonce)to produce the result. - After the round, the server reveals the unhashed seed so you can verify.
What it proves
That the result wasn't changed after the round started.
What it doesn't prove
- The odds posted are accurate.
- The site won't ban you for winning.
- Withdrawals will be honored.
