# Provably Fair

Using `publickey`, `proof`, and `alpha`, we can verify that `beta` is the correct VRF hash. With `beta` verified, we can get the modulo of it divided by the size of the revolver, concatenate the result with `salt`, generate a SHA-256 hash, and verify that this hash is equal to the one passed to `newGame`, therefore proving that the bullet's chamber index was randomly generated at the start of the game.
