Description: peer-to-peer network based anonymous digital currency - CLI tools
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.
.
By default connects to an IRC network to discover other peers.
.
Full transaction history is stored locally at each client. This
requires 150+ MB of space, slowly growing.
