 .A Solution to a Distributed Computing Problem
 ****
-((("Byzantine Generals Problem")))Satoshi Nakamoto's invention is also a practical solution to a previously unsolved problem in distributed computing, known as the "Byzantine Generals' Problem." Briefly, the problem consists of trying to agree on a course of action by exchanging information over an unreliable and potentially compromised network. 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 science 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.
