Binary package “bitcoind” in ubuntu oneiric

peer-to-peer network based anonymous digital currency - daemon

 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.
 This package provides bitcoind, a combined daemon and CLI tool to
 interact with the daemon.
