                  Bitcoin is an experimental new digital currency that enables instant payments to anyone, anywhere in the world.
                  Bitcoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out <a href="bitcoin.pdf">collectively by the network</a>.
                  Bitcoin is also the name of the open source software which enables the use of this currency.
