A predefined method for coming to a consensus on the state of the system. For example, when portions of the system participants claim there is State_A and the rest of the participants claim there is State_B, there is a conflict. The system will automatically resolve this conflict by choosing the “valid” state as being the one from whichever group adds the next block of data. Any transactions “lost” by the state not chosen are added back into the pending transaction pool.
