Bitcoin is the first decentralized open source peer-to-peer payment network that operates on a cryptographic protocol. The Bitcoin network is a consensus network that enables a new payment system and digital money. Transactions are recorded into a distributed public database known as the blockchain, with consensus achieved by a proof-of-work system called mining. The blockchain is distributed internationally using peer-to-peer file sharing technology similar to BitTorrent.Bitcoin is powered by its users with no central authority or middlemen. The network is made up of users like yourself so no bank or payment processor is required between you and whoever you're trading with. This decentralization is the basis for Bitcoin's security and freedom. It's an open source technology and anyone can be a part of the network.Bitcoin is the biggest opportunity for innovation that the world has seen since the Internet. An idea whose time has come.
