bitcoin-qt

peer-to-peer network based digital currency - GUI

Bitcoin is a free open source peer-to-peer electronic cash system that is completely decentralized, without the need for a central server or trusted parties. Users hold the crypto keys to their own money and transact directly with each other, with the help of a P2P network to check for double-spending. Unless pruning is enabled, full global transaction history is stored locally at each client, which may require large amounts of disk space. This package provides Bitcoin-Qt, a GUI for Bitcoin based on Qt.
