A major investigation by The New York Times has concluded that British cryptographer Adam Back is Satoshi Nakamoto, the pseudonymous inventor of Bitcoin. Following a yearlong analysis of decades-old internet archives and private emails, journalists John Carreyrou and Dylan Freedman pinpointed the 55-year-old computer scientist using extensive linguistic forensics and historical evidence.
The reporters discovered striking similarities between Nakamoto's digital footprint and Back's writings. Using computational text analysis to filter out over 600 candidates, the investigation revealed that Back was the only individual among early cryptography enthusiasts who shared Nakamoto's highly distinct grammatical quirks. These included specific hyphenation errors, double-spacing habits, British spelling conventions, and the use of identical technical jargon.
Historical records from the 1990s Cypherpunks mailing list further bolstered the conclusion. The Times found that Back had outlined nearly every technical and philosophical component of Bitcoin a decade before its 2008 launch. Back is also the original inventor of Hashcash, a spam-prevention mechanism that Nakamoto directly repurposed to mine Bitcoin. The investigation also noted the suspicious timing of their public activities: Nakamoto's sudden disappearance in 2011 perfectly mirrored Back's delayed, yet highly influential, emergence in the public Bitcoin community.
When confronted with the investigative findings during a Bitcoin conference in El Salvador, Back repeatedly denied being Nakamoto. However, the journalists reported a critical verbal slip during the interview where Back seemingly acknowledged authoring one of Nakamoto's exact quotes, ultimately cementing the publication's conclusion that the current Blockstream executive is the true architect of the $2.4 trillion cryptocurrency industry.
