Each bitcoin, or fraction of a bitcoin, is associated with a unique address, managed by a user’s encrypted ‘wallet’ that needs have no ties to a real-world identity. Transactions are processed and verified by a distributed computing task called ‘mining’ that can be run on any hardware connected to the Internet worldwide. Often run on specialized hardware, mining is computationally expensive, but users are compensated for this cost, as new bitcoins are generated for them as part of the mining process.
The trustless, unregulatable, anonymous nature of bitcoin rapidly attracted the interest of futurists and libertarians, excited by the potentially disruptive implications of the technology in a world still reeling from the 2008 banking crisis. The genesis block, the first coins mined by Satoshi themself, contains a reference to a January 2009 New York Times headline: “Chancellor on brink of second bailout for banks.”
