Bitcoin is a new digital currency that enables reliable, 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 collectively by the network. Bitcoin is also the name of the open source software which enables the use of this currency.
Bitcoin verifies transactions with the same state-of-the-art encryption that is used in military and government applications.
Bitcoin is free open-source software. Nobody owns it; the most popular client is maintained by a community of developers and other good clients are available. Furthermore, the network is run by a decentralized network of thousands of servers and desktops.
Using the Bitcoin network is free, except for a voluntary fee you can use to speed up transaction processing.
Bitcoin payments can be accepted from any country in the world, with no risk of chargebacks or reversals. Low fees mean you can pass the savings on to your customers and get a price advantage over other merchants. Confirmed transactions are protected by the large and growing computational power of the network.
