SHA512/256 is a strange choice for instantiating HMAC - while SHA512/256 is secure against length-extension attack, HMAC is secure against it as well; even when performance advantage on 64-bit platforms considered, SHA256 has better interoperability. Space - falling faster than light? The second person has enough information to calculate the result of the game on their own, and so they might pretend to have their computer crash to avoid paying out larger winnings. A HMAC is a small set of data that helps authenticate the nature of message; it protects the integrity and the authenticity of the message.
