Provably Fair Outcome

MoneyPot uses a Provably Fair algorithm that calculates raw outcomes from generated SHA-256 hashes. The Bet Hash is generated from the resulting hash of two unique hashes, the Server Seed and the Server Salt. The Server Seed and the Server Salt are both unique 64 character strings.

The Raw Outcome is based on a combination of the Server Seed and the Client Seed. After both are hashed together with SHA-256, we trim the resulting hash of the two to the first eight characters and then converted to an integer using Base16.

$outcome = intval(substr(hash('sha256', $serverSeed . $clientSeed), 0, 8), 16);

Javascript (cryptocoinjs / sha256)

var output = Number.parseInt(sha256(serverSeed + clientSeed).slice(0, 8), 16);
