Every time anyone buys or sells bitcoin, the swap gets logged. Several hundred of these back-and-forths make up a block. Why bother using it? True to its origins as an open, decentralized currency, bitcoin is meant to be a quicker, cheaper, and more reliable form of payment than money tied to individual countries.

And since there is a finite number to be accounted for, there is less of a chance bitcoin or fractions of a bitcoin will go missing. But while fraudulent credit-card purchases are reversible, bitcoin transactions are not.
Satoshi Nakamoto, bitcoin's enigmatic founder, arrived at that number by assuming people would discover, or "mine," a set number of blocks of transactions daily.
