# Who is Satoshi Nakamoto? What the record actually shows, and what it does not Satoshi Nakamoto is the name used by the author of Bitcoin’s white paper and early software and by the correspondent who helped launch the network. The cited documents establish that work, but do not establish a real-world identity. In 2024 the High Court in England and Wales found that Craig Wright was not Satoshi and did not author the white paper or create Bitcoin; that finding does not identify Satoshi.

The sender, signing as Satoshi Nakamoto, said he had been working on “a new electronic cash system that’s fully peer-to-peer, with no trusted third party,” and gave a link to a paper at bitcoin.org. That announcement is the public starting point in the evidence cited here. Its author line gives a name, an address at a free webmail service, and the website. Nothing else. The paper describes the design in plain terms: a purely peer-to-peer version of electronic cash, so that online payments can go directly from one party to another without a bank in the middle. It solves the problem of the same coin being spent twice by having a network of computers timestamp transactions into a chain secured by computational work. The rest of the paper is design, and none of it is about the author. What matters for the identity question is what the paper does not contain. There is no biography, no institution, no funding line, no co-author. The author line alone does not identify the person or people who used that name. Evidence: [“Bitcoin P2P e-cash paper,” message to the Cryptography mailing list](https://www.metzdowd.com/pipermail/cryptography/2008-October/014810.html); [Bitcoin: A Peer-to-Peer Electronic Cash System](https://bitcoin.org/bitcoin.pdf) ## What Satoshi actually left behind: software, forum posts and emails On 11 February 2009 Satoshi posted on the P2P Foundation forum: “I’ve developed a new open source P2P e-cash system called Bitcoin.” The software had already been released, and this post invited people to try it. From then until December 2010 Satoshi wrote steadily: forum posts, release notes, and private emails to the handful of developers who joined in. This site collects that record, sorted by topic, in its Satoshi correspondence library. The cited accounts describe electronic correspondence. Hal Finney, the cryptographer who received the first bitcoin transaction, wrote in 2013 that he had assumed he was “dealing with a young man of Japanese ancestry who was very smart and sincere.” That was an impression, and Finney said so. Gavin Andresen, the developer Satoshi handed the project to, later testified that the original code looked as if a small number of people, possibly one, had written it. Those statements describe impressions and inferences, not proof of identity. The messages provide evidence about development and technical decisions. They do not establish the author’s real-world identity.

He cautioned that his parsing and classification were uncertain and that the link to Satoshi was not a mathematical identification. This is historical analysis of a selected block set. Its low-spending observation should not be restated as a current audit or as proof of a named person’s wealth. See the [Patoshi pattern](/encyclopedia/patoshi-pattern/) for the method and its limits. Evidence: [“The Well Deserved Fortune of Satoshi Nakamoto, Bitcoin creator, Visionary and Genius”](https://bitslog.com/2013/04/17/the-well-deserved-fortune-of-satoshi-nakamoto/) ## Craig Wright’s claim and the court’s findings One prominent person who publicly claimed to be Satoshi was Craig Wright, an Australian-born IT security consultant who announced it on 2 May 2016 with the backing of two well-known Bitcoin figures and a blog post that was supposed to contain cryptographic proof. It did not. When a non-profit called the Crypto Open Patent Alliance (COPA) sued to settle the question, the case went to trial in London in February 2024. On 14 March 2024, at the end of closing arguments, Mr Justice Mellor announced the result from the bench. He said the evidence was “overwhelming,” and declared that Wright is not the author of the white paper, is not the person who used the name Satoshi Nakamoto between 2008 and 2011, did not create the Bitcoin system, and did not write its early software. His written judgment of 20 May 2024 found that Wright had “lied to the Court extensively and repeatedly” and had forged documents “on a grand scale.” That is as close as the identity question has come to a formal answer, and it is a negative one. The court did not say who Satoshi is; it said who Satoshi is not. Our [article on the COPA ruling](/encyclopedia/craig-wright-copa-ruling/) covers the case, the injunctions that followed and the contempt finding. Evidence: [Crypto Open Patent Alliance v Craig Steven Wright, [2024] EWHC 1198 (Ch), approved judgment](https://www.judiciary.uk/wp-content/uploads/2024/05/COPA-v-Wright-Judgment.pdf) ## The cited record does not establish a real-world identity The paper, software and correspondence establish work published under the Satoshi pseudonym. Mining-pattern studies add inferences about early activity. Neither type of evidence supplies a verified real-world identity, and the court’s rejection of Craig Wright does not identify the original author. A claim about identity needs evidence that bridges the pseudonym and a person, not just a resemblance or a shared interest. Our [origins dossier](/history/origins-of-bitcoin/) and [Satoshi hub](/satoshi/) collect the records discussed here so readers can inspect that boundary. Evidence: [Bitcoin: A Peer-to-Peer Electronic Cash System](https://bitcoin.org/bitcoin.pdf); [Crypto Open Patent Alliance v Craig Steven Wright, [2024] EWHC 1198 (Ch), approved judgment](https://www.judiciary.uk/wp-content/uploads/2024/05/COPA-v-Wright-Judgment.pdf); [“The Well Deserved Fortune of Satoshi Nakamoto, Bitcoin creator, Visionary and Genius”](https://bitslog.com/2013/04/17/the-well-deserved-fortune-of-satoshi-nakamoto/) ## Match each identity claim to the evidence that could support it Start with the narrow claim a document supports. An author name on the paper attributes that text to the Satoshi pseudonym. The announcement records a message sent under that name. Neither document, by itself, supplies a verified real-world identity. Keep three questions apart when reading a profile: who published the software or messages, which mining activity a researcher has grouped together, and who controlled particular keys. Evidence offered for one question should not silently be presented as proof of the others. This entry describes the public record rather than choosing a candidate.

The documents cited here do not establish a real-world identity. The 2024 High Court judgment rejects Craig Wright’s claim and makes findings about his evidence; it does not identify the original author. Evidence: [Crypto Open Patent Alliance v Craig Steven Wright, [2024] EWHC 1198 (Ch), approved judgment](https://www.judiciary.uk/wp-content/uploads/2024/05/COPA-v-Wright-Judgment.pdf); [Bitcoin: A Peer-to-Peer Electronic Cash System](https://bitcoin.org/bitcoin.pdf) ### How many bitcoins does Satoshi Nakamoto own? No certain total can be assigned to a known person. Lerner’s 2013 estimate attributed roughly one million BTC to a dominant early mining pattern, with explicit classification uncertainty. The connection between that pattern and Satoshi is circumstantial, and unspent status must be dated to the analysis. Evidence: [“The Well Deserved Fortune of Satoshi Nakamoto, Bitcoin creator, Visionary and Genius”](https://bitslog.com/2013/04/17/the-well-deserved-fortune-of-satoshi-nakamoto/) ### Is Satoshi Nakamoto Japanese? The pseudonym and profile statements do not establish nationality. Finney recalled an initial impression of a person of Japanese ancestry, but that was his impression of an online correspondent. The cited documents do not verify a nationality, age or location. Evidence: [“Bitcoin and me (Hal Finney)”](https://bitcointalk.org/index.php?topic=155054.msg1644175#msg1644175); [“Bitcoin open source implementation of P2P currency,” P2P Foundation forum post](https://satoshi.nakamotoinstitute.org/posts/p2pfoundation/1/) ## Claims and scope ### who-is-satoshi-nakamoto-quick-answer Satoshi Nakamoto is the name used by the author of Bitcoin’s white paper and early software and by the correspondent who helped launch the network. The cited documents establish that work, but do not establish a real-world identity. In 2024 the High Court in England and Wales found that Craig Wright was not Satoshi and did not author the white paper or create Bitcoin; that finding does not identify Satoshi.
