Satoshi Nakamoto

• 1. Introduction

  ›

  Satoshi Nakamoto built one of the most consequential financial systems in history and then vanished. On the 31st of October 2008, a white paper appeared on a cryptography mailing list at metzdowd.com. It described a digital cryptocurrency called Bitcoin. The author gave a name, a country of residence, and a date of birth. None of those details have ever been confirmed. What we know is this: the person or persons who wrote under the name Satoshi Nakamoto created a global currency, amassed a fortune that as of the 14th of July 2025 was worth nearly $135 billion, and then went silent in 2011. A wallet holding an estimated 1.1 million bitcoins has not moved since 2010. Somewhere out there, someone knows who Nakamoto really is. The question that has consumed cryptographers, journalists, and courts for over a decade is whether that someone is Nakamoto themselves.

  Nakamoto later said that writing bitcoin's code began in the second quarter of 2007. On the 18th of August 2008, he registered the domain bitcoin.org and built a website there. The white paper he published that October bore a precise title: "Bitcoin: A Peer-to-Peer Electronic Cash System." On the 9th of January 2009, he released version 0.1 of the software on SourceForge and launched the network. The first block he created, the so-called genesis block, carried a reward of 50 bitcoins. Embedded in that block was a line of text: "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks." It was lifted from the front page of the British newspaper The Times on that exact date. Observers have read it as both a timestamp and a pointed comment on the fragility of fractional-reserve banking. Nakamoto worked directly on the source code until mid-2010, then handed control of the repository and the network alert key to developer Gavin Andresen. He also transferred several related domains to prominent members of the bitcoin community. In 2011, he sent an email to co-developer Mike Hearn saying he had "moved on to other things." After that, nothing.

  On his P2P Foundation profile, as of 2012, Nakamoto described himself as a 37-year-old man living in Japan, born on the 5th of April 1975. Author Dominic Frisby called that birthdate an "obscure but brilliant reference," noting it pointed to Executive Order 6102, which banned private gold ownership in the United States, and to 1975, the year that order was repealed. Swiss software engineer Stefan Thomas graphed the timestamps of more than 500 of Nakamoto's bitcoin forum posts. The chart showed a steep drop in activity between 5 a.m. and 11 a.m. Greenwich Mean Time, which corresponded to 2 p.m. to 8 p.m. Japan Standard Time. Someone genuinely based in Japan would have been fully awake during those hours. The pattern persisted on weekends, suggesting consistent sleep, not work obligations, was the explanation. Security researcher Dan Kaminsky, after reading bitcoin's code, said Nakamoto was either a "team of people" or a "genius." Developer Laszlo Hanyecz, who had emailed Nakamoto directly, believed the code was too well-designed for a single person. Gavin Andresen described the work as that of a "brilliant coder, but it was quirky." The British English scattered through the source code and forum posts drew equal attention: phrases like "bloody hard", "lad", and "mate"; spellings like "grey" and "colour"; the word "maths" rather than math. Those details, combined with the Times headline embedded in the genesis block, led many analysts to conclude Nakamoto was located in the United Kingdom.

  Adam Back, inventor of Hashcash, a direct precursor to bitcoin, was named in the body of the bitcoin white paper itself. In 2020, the YouTube channel Barely Sociable argued publicly that Back was Nakamoto; widespread discussion followed. The 2024 film Money Electric: The Bitcoin Mystery pressed the case further, pointing to a similar writing style between Back and Nakamoto, Back's move to Malta, and his appearance on the Bitcointalk forum on the 17th of April 2013, the same day the scale of Nakamoto's holdings first became public. In the film, Back said: "I thought you might think I'm Satoshi. And I don't want that to be on the record, really." In 2026, investigative journalist John Carreyrou of The New York Times reported on stylometric analyses and circumstantial timing factors linking Back to Nakamoto. Back denied being Nakamoto multiple times during an in-person interview at a bitcoin conference in El Salvador. Hal Finney, born on the 4th of May 1956 and died on the 28th of August 2014, was the first person other than Nakamoto to use the bitcoin software. He filed the earliest bug reports and made the first improvements. Forbes journalist Andy Greenberg asked the writing analysis firm Juola and Associates to compare Finney's writing to Nakamoto's; they found it the closest resemblance they had encountered, closer than any other candidate. But after Greenberg met Finney, reviewed their email exchanges, and examined Finney's wallet history, including the first-ever bitcoin transaction from Nakamoto to Finney, he concluded Finney was telling the truth in his denial. Nick Szabo, a decentralized-currency enthusiast who published a paper on "bit gold", another bitcoin precursor, was linked to the white paper by blogger Skye Grey in December 2013 through stylometric analysis. In 2015, Nathaniel Popper wrote in The New York Times that "the most convincing evidence pointed to a reclusive American man of Hungarian descent named Nick Szabo." Szabo has denied being Nakamoto. In a July 2014 email to Dominic Frisby, he wrote: "Thanks for letting me know. I'm afraid you got it wrong doxing me as Satoshi, but I'm used to it."

• 5. The Wrong Answers

  ›

  In March 2014, Newsweek journalist Leah McGrath Goodman published a high-profile article identifying Dorian Prentice Satoshi Nakamoto, a Japanese-American man in California whose legal birth name actually is Satoshi Nakamoto. Goodman pointed to his background as a systems engineer on classified defence projects and his libertarian turn after being laid off twice in the early 1990s. Her key piece of evidence was a remark Dorian Nakamoto made during a brief interview: "I am no longer involved in that and I cannot discuss it. It's been turned over to other people. They are in charge of it now." The story triggered a media frenzy; reporters camped outside his house and chased him by car. Later that day, the long-dormant P2P Foundation account attributed to Satoshi Nakamoto posted its first message in five years: "I am not Dorian Nakamoto." Dorian subsequently said he had misunderstood Goodman's question entirely, believing she was asking about classified work he had done for military contractors, and in a separate Reddit interview he said he thought she was asking about his time at Citibank. In September, the P2P Foundation account posted that it had been hacked, throwing doubt on the earlier denial as well. Craig Steven Wright presented a far more aggressive case for himself. On the 8th of December 2015, Wired published that Wright "either invented bitcoin or is a brilliant hoaxer." Gizmodo ran a story claiming Nakamoto was a joint pseudonym for Wright and computer forensics analyst Dave Kleiman, who died in 2013. Wright's claim drew early support from Gavin Andresen and former Bitcoin Foundation director Jon Matonis, but bitcoin developer Peter Todd said Wright's supposed cryptographic proof contained nothing of the sort, and Dan Kaminsky called the claim "intentional scammery." Wright registered US copyright for the bitcoin white paper in 2019; the US Copyright Office clarified that this registration was not government recognition of his authorship. In March 2024, Judge James Mellor of the UK High Court ruled in the COPA case that Wright was not Satoshi Nakamoto, finding that documents Wright submitted as evidence were forgeries and that he had "lied to the court extensively and repeatedly." On the 19th of December 2024, Wright was sentenced to one year in prison, suspended for two years, for contempt of court.

  ›

  As of 2021, Nakamoto is estimated to hold somewhere between 750,000 and 1,100,000 bitcoins. In November 2021, when bitcoin's price exceeded $68,000, that holding placed him as the 15th-richest person in the world, with a net worth of up to $73 billion. By the 14th of July 2025, each bitcoin was priced above $123,000, putting the wallet's value at nearly $135 billion. That wallet has not moved since 2010. Every cryptography conference, every court case, every stylometric analysis ultimately circles back to the same fact: if Nakamoto ever spends those coins, the mystery ends. The developer community has long said that moving the earliest mined bitcoins would be the only truly convincing proof of identity. Until that happens, Nakamoto's silence is its own kind of answer.

• 7. Monuments to a Ghost

  ›

  In 2021, a bust dedicated to Satoshi Nakamoto was installed in Budapest, Hungary. A statue by sculptor Valentina Picozzi was unveiled in Lugano, Switzerland, deliberately designed to look different depending on the angle from which you view it. The statue was stolen and thrown into a lake, then recovered. A testimonial in honour of cypherpunk Len Sassaman, proposed as a Nakamoto candidate, was permanently embedded in bitcoin's blockchain, discovered when security researcher Dan Kaminsky presented his findings at the 2011 Black Hat Briefings. The London Review of Books published a piece about Nakamoto by Andrew O'Hagan in June 2016. A 2026 documentary titled "Finding Satoshi" proposed that Nakamoto was a partnership between Sassaman and Hal Finney. Monuments, films, court verdicts, and a recovered lake statue: these are the traces of a person who, as of 2011, described themselves only as having moved on.
