Satoshi Nakamoto is the name used by the person or people who created Bitcoin. In 2011 they stopped writing and vanished, leaving behind a design, a few thousand messages and a fortune that has never been touched.
What we know
On 31 October 2008 someone using the name Satoshi Nakamoto sent a nine-page paper titled Bitcoin: A Peer-to-Peer Electronic Cash System to a cryptography mailing list. On 3 January 2009 the first block of the Bitcoin chain was created, containing a newspaper headline about a bank bailout. Software followed within days, and Satoshi wrote on forums and by email for about two years, working with early developers.
Satoshi's last known messages date from 2011. In one of the final emails, Satoshi said they had moved on to other things. After that the account went silent.
What the writing suggests
Satoshi's writing used British-style spellings and phrases, and the timing of messages suggested a regular sleep pattern, but these are clues, not proof. A profile created for Satoshi claimed they were a man living in Japan, which nobody has been able to verify.
The coins that never moved
Analysts who studied the earliest blocks believe one miner, widely assumed to be Satoshi, collected about a million bitcoin in the first year or so. According to those estimates, none of it has ever been spent. If a wallet from that period ever moved, it would be a major event.
People who have been suggested
- Hal Finney, a cryptographer who received the first Bitcoin transaction. He died in 2014 and always denied being Satoshi.
- Nick Szabo, who designed a similar idea called bit gold. He has denied it.
- Adam Back, creator of Hashcash, which Bitcoin builds on. He has denied it.
- Dorian Nakamoto, a Californian engineer named in a 2014 magazine article. He denied it, and the article was widely criticised.
- Craig Wright, an Australian computer scientist who publicly claimed to be Satoshi. In March 2024 a UK High Court judge ruled that he is not.
None of these suggestions has been proven. The simplest proof would be to sign a message with one of the early keys, and nobody has done that convincingly.
Why it matters
Bitcoin works without any central authority, so Satoshi's absence is part of the design. Many people see the mystery as a feature: nobody can be pressured, arrested or asked to change the rules. Others worry about what would happen if the early coins ever moved.
Frequently asked questions
Is Satoshi Nakamoto one person or a group?
Nobody knows. The name could belong to one person or a small team.
Has anyone proved they are Satoshi?
No. The only way would be to sign a message with one of the early keys, and no claim has done that convincingly. A UK court ruled in 2024 that Craig Wright is not Satoshi.
How many bitcoin does Satoshi own?
Analysts estimate around a million, based on patterns in the earliest blocks, but this is an estimate and not a confirmed figure.
When did Satoshi last communicate?
Around 2011.
Could Satoshi's coins ever be spent?
Yes, if the owner still has the keys. Nothing has moved so far.
