Three hashes are created on the beginning of every round: Client Hash, Server hash and Full Hash. The Client Hash is sent to the user with the hosting and joining Tradeoffer and it's also shown on the lobby, it's a short string you can easily recognize. The Server Hash is not shown to anyone, it's used to generate the Full Hash and it's only revealed here on the Provably Fair page. The Winning Flip is also generated when the Lobby is hosted and it's hidden between these 2 hashes, the Winning Flip can either be 1 or 2, and it's not even logged in the server's database. Our Provably Fair does not use modules / tickets as those would have to be logged in the database.
The Full Hash is then generated from 3 elements: sha256(ServerHash-WinningFlip-ClientHash). This Full Hash is also shown on the lobby for verification purposes. You can enter this Full Hash or the Lobby ID below to verify it.
