Nakamoto's invention is also a viable solution to the "Byzantine general" problem, which has not been solved in distributed computing. In simple terms, the problem involves trying to reach an operational consensus through the exchange of information in an unreliable and potentially threatening network. Nakamoto's solution, which uses the concept of proof of work to reach consensus without a central trust authority, represents a scientific breakthrough in distributed computing and has gone beyond the broad applicability of money. It can be used to achieve decentralized online consensus for fair elections, human rights, asset registration, and digital notarization.
