A somewhat technical explanation of how Bitcoin works
Bitcoin is a new digital currency and peer-to-peer payment network. Accounts and software to participate in the network is free and open source - Anyone can freely participate! Operating as a true p2p network, there is no central authority to authorize or block transactions. Bitcoin transactions are anonymous and instant across a few millimeters, or thousands of miles across any geo/political border in any amount (pennies or millions). The security and value of Bitcoin is backed by math, cryptography, and peer consensus - not the self interest or whims of politicians or bankers. It is the first truly debt free, deflationary, global currency!
