Lockstep protocol
http://dbpedia.org/resource/Lockstep_protocol an entity of type: Software
The lockstep protocol is a partial solution to the look-ahead cheating problem in peer-to-peer architecture multiplayer games, in which a cheating client delays their own actions to await the messages of other players. A client can do so by acting as if they're suffering from high latency; the outgoing packet is forged by attaching a time stamp that is prior to the actual moment the packet is sent. To avoid this method of cheating, the lockstep protocol requires each player to first announce a "commitment" (e.g. hash value of the action); this commitment is a representation of an action that:

* Cannot be used to infer the action; and
* Easily compares whether an action corresponds with a commitment. Once all players have received the commitments, they reveal their actions, which are compared with the corresponding commitments to ensure that the commitment is indeed the sent action.
