Nobody knows who Satoshi Nakamoto is. It is the pseudonym of the person, or possibly the group, who published the bitcoin white paper in 2008, launched the network in January 2009 and stopped writing to anyone in 2011, and every claimed real identity since then has been unproven or disputed.
What we do have is a detailed paper trail: emails, forum posts, code and a few clues about habits. Here is what that record shows, and what it doesn't.
What Satoshi Nakamoto actually did
Everything below comes from Satoshi's own public writing and the blockchain itself, most of it archived by the Satoshi Nakamoto Institute.
- October 31, 2008. Satoshi posted the white paper, Bitcoin: A Peer-to-Peer Electronic Cash System, to a cryptography mailing list (read the white paper).
- January 3, 2009. Satoshi mined the genesis block, the first block of the chain, with a newspaper headline tucked inside.
- January 9, 2009. The first version of the Bitcoin software was announced on the same mailing list, and other people started running it.
- January 12, 2009. The first bitcoin transaction went from Satoshi to cryptographer Hal Finney, an early supporter whose story is in our Running bitcoin guide.
- 2009 to 2010. Satoshi wrote code, answered questions on the BitcoinTalk forum and, in February 2010, drew the B with two strokes that became the bitcoin symbol.
- Late 2010. Satoshi handed more and more of the project to developer Gavin Andresen. The last public forum post is dated December 12, 2010.
- April 2011. On April 23, in a private email to developer Mike Hearn, Satoshi wrote "I've moved on to other things" and said the project was in good hands. A few days later came a short email to Gavin Andresen. These are the last messages widely accepted as genuine.
After that, silence. No interviews, no photos, no signed messages that experts agree are genuine.
Clues from the writing
People have studied every line Satoshi wrote, and a few details come up again and again:
- A claimed profile. A P2P Foundation profile said Satoshi was a man living in Japan, born April 5, 1975. Nothing has ever confirmed it.
- British spellings. Posts and code comments use British spellings and phrases like "bloody hard", which led many to suspect someone from Britain or the Commonwealth rather than Japan.
- Unusual care with privacy. Satoshi never revealed a location, a voice or a face, which is why the clues stay this thin.
None of these clues points to a single person. They mostly rule people out.
Famous guesses that never held up
Over the years journalists, filmmakers and a few self-promoters have put names forward. Here is how the best-known claims stand, stated as fairly as we can:
- Dorian Nakamoto. A March 2014 Newsweek cover story named this California engineer, pointing in part to his birth name, Satoshi. He denied it firmly and said he had never worked on bitcoin.
- Hal Finney. As the first person to receive bitcoin, he drew speculation. He denied being Satoshi before he died in 2014.
- Nick Szabo. His earlier "bit gold" idea made him a common guess. He has consistently denied it.
- Craig Wright. He claimed for years to be Satoshi. In March 2024 a judge in the UK High Court ruled that he is not.
- Peter Todd. A 2024 HBO documentary suggested this bitcoin developer. He denied it and called the claim a marketing angle for the film.
The honest scoreboard: zero proven identities. The easy proof would be to sign a message with a key known to belong to Satoshi, and nobody has done that.
How many bitcoin does Satoshi own?
Estimates are around 1 million BTC. They come from researchers, starting with Sergio Demian Lerner in 2013, who spotted a distinctive pattern in early mined blocks and attributed those blocks to one miner, likely Satoshi. The figure is an estimate, not a verified fact: no one has proven which coins are Satoshi's.
What is clear is that the coins linked to that early mining pattern have stayed put. That is why questions like "did Satoshi sell his bitcoin" and "how wealthy is Satoshi Nakamoto" have no firm answer. Any dollar figure depends entirely on the price of the day, and if those coins ever moved, it would be front page news.
Is Satoshi alive?
We don't know. The last accepted message is from April 2011, and silence is not evidence either way. Some people think Satoshi chose to disappear so bitcoin could grow without a founder at the center, and that reading fits the record well. Bitcoin has no CEO to subpoena, no founder to follow and no leader who can change the rules alone.
Satoshi's last message, in context
The April 2011 email to Mike Hearn was not a dramatic farewell. Hearn had written about a technical idea, Satoshi replied to it and added the short line about moving on. In the email to Andresen a few days later, Satoshi asked Gavin Andresen to stop describing him as a mysterious shadowy figure. Read together, they sound like someone quietly stepping back from a project they believed could stand on its own.
Wearing a tribute
Satoshi has become bitcoin's folk hero, and plenty of bitcoiners like to wear the name. Our Satoshi tee is an independent fan design: SATOSHI in yellow above a cartoon smiley whose eyes are bitcoin symbols, with its tongue sticking out. It is not affiliated with, or endorsed by, Satoshi Nakamoto, whoever that may be.
One thing to know when you search for it: "Satoshi Nakamoto" is also the name of an unrelated designer clothing label. Our tee has nothing to do with that label. If you prefer to honor Satoshi more quietly, the Bitcoin Logo tee carries a small orange version of the B Satoshi first sketched.
