The Short Answer
- Satoshi Nakamoto is the pseudonym used by Bitcoin's anonymous founder(s).
- Several individuals have been speculated to be Satoshi: physicist Dorian Nakamoto, computer engineer Nick Szabo, Japanese mathematician Shinichi Mochizuki, and even corporate consortia—though none have been confirmed.
Who Is Satoshi Nakamoto?
Satoshi Nakamoto is the enigmatic inventor of Bitcoin, whose true identity remains unknown. The name is widely believed to be a pseudonym, and some theorize it represents a group rather than an individual.
Satoshi claimed to be a 37-year-old man living in Japan, but evidence suggests British ties:
- Forum posts used British English (e.g., "bloody hard," "maths," "colour").
- Bitcoin’s genesis block referenced The Times of London.
- Activity patterns aligned with UK waking hours (2–8 PM Japan time).
In 2008, Satoshi published the seminal paper Bitcoin: A Peer-to-Peer Electronic Cash System, laying the foundation for blockchain technology and ushering in the era of decentralized finance.
Why Did Satoshi Create Bitcoin?
Satoshi aimed to eliminate third-party intermediaries in financial transactions, citing:
- Excessive fees: Traditional systems impose high costs on users.
- Trust erosion: Central banks and banks mismanage currency and privacy.
- Limited micropayments: Administrative overhead restricts small transactions.
In a 2009 forum post, Satoshi wrote:
"The root problem with conventional currency is all the trust required to make it work. Central banks must be trusted not to debase currency, but history is full of breaches of that trust."
