One of the greatest challenges in distributed computing is reaching consensus among nodes that can't trust each other. The Byzantine Generals' Problem describes this scenario, where generals attempt to coordinate an attack without being able to verify messages from other armies. #Bitcoin solves this problem by using a decentralized peer-to-peer network, backed by cryptography and game theory, that allows nodes to agree on a single version of the truth without relying on intermediaries or trusted third parties. This creates a more secure and transparent way of conducting transactions than traditional systems based on centralized authorities like #USDollar or fiat currencies.
