((("Byzantine Generals' Problem")))Satoshi Nakamoto's invention is
also a practical and novel solution to a problem in distributed
computing, known as the "Byzantine Generals' Problem." Briefly, the
problem consists of trying to agree on a course of action or the state
of a system by exchanging information over an unreliable and potentially
compromised network. ((("central trusted authority")))Satoshi Nakamoto's
solution, which uses the concept of Proof-of-Work to achieve consensus
_without a central trusted authority_, represents a breakthrough in
distributed computing and has wide applicability beyond currency. It can
be used to achieve consensus on decentralized networks to prove the
fairness of elections, lotteries, asset registries, digital
notarization, and more.
