Satoshi Nakamoto (pseudonymous)

Satoshi Nakamoto is the pseudonymous creator of Bitcoin, the first digital currency that operates without a central authority. In 2008, Nakamoto published a paper outlining how Bitcoin could enable secure, peer-to-peer transactions using blockchain technology—a public ledger maintained by a network of computers. Nakamoto implemented the system in 2009 and remained active in its development until gradually stepping back. Despite widespread speculation, Nakamoto’s true identity remains unknown, exemplifying privacy and decentralization principles fundamental to Bitcoin's design.
