Satoshi Nakamoto is the pseudonym of the person or people who developed Bitcoin and introduced cryptocurrency with the paper “Bitcoin: A Peer-to-Peer Electronic Cash System” in 2008. Nakamoto created the blockchain system, which timestamps and encrypts transaction information, preventing duplication and requiring validation. The network uses a “proof-of-work” consensus mechanism called “mining” to verify Bitcoin’s authenticity.
Nakamoto has never been met in person, and their true identity remains unknown. The last confirmed message from Nakamoto was in April 2011, and a final email requested not to be seen as a “mysterious shadowy figure.” Though many have been speculated to be Nakamoto—including Hal Finney, Dorian Nakamoto, Craig Wright, and Adam Back—none of these speculations have been proven.
