One of the core challenges of designing a digital currency involves something called the double-spending problem. Users willing to devote CPU power to running a special piece of software would be called miners and would form a network to maintain the knightmb bitcoin chain collectively.

When they weren’t busy mining, the faithful tried to solve the mystery of the man they called simply Satoshi.
Someone else wondered whether the name might be a sly portmanteau of four tech companies: SAmsung, TOSHIba, NAKAmichi, and MOTOrola. It seemed doubtful that Nakamoto was even Japanese. His English had the flawless, idiomatic ring of a native speaker. Perhaps, it was suggested, Nakamoto wasn’t one man but a mysterious group with an inscrutable purpose—a team at Google, maybe, or the National Security Agency.
