Who Is the Founder of Bitcoin?

Short answer

• Bitcoin was created by someone using the name Satoshi Nakamoto. That name is a pseudonym, and the real identity behind it has never been established. No person has ever proved they are Satoshi, and no court has ever decided who Satoshi is.
• What can be verified is the work. Satoshi published the Bitcoin white paper, "Bitcoin: A Peer-to-Peer Electronic Cash System," on 31 October 2008, released the first Bitcoin software in January 2009, mined the first block on 3 January 2009, and sent the first transaction to cryptographer Hal Finney on 12 January 2009.
• Satoshi stopped posting publicly in December 2010 and stopped answering private messages from other developers in April 2011. Since then, no verified communication from Satoshi has appeared.
• Several people have been named as Satoshi or have claimed the title. The most prominent claimant, Craig Wright, was ruled not to be Satoshi by the High Court of England and Wales in March 2024. The others named most often, including Hal Finney and Nick Szabo, either denied it or never claimed it, and the evidence for each is circumstantial.
• The honest answer to "who is the founder of Bitcoin" is therefore twofold: the founder is Satoshi Nakamoto, and nobody knows who Satoshi Nakamoto is. The rest of this article separates what the record proves from what people have guessed.

The Short Version of a Long Mystery

Bitcoin is the most valuable and most widely known cryptocurrency in the world, and its founder is unknown. That sentence sounds like a contradiction, and it is the reason this question keeps being asked. Most inventions have a named inventor with a face, a biography, and a patent file. Bitcoin has a name, a nine page paper, a few hundred forum posts, and a silence that has lasted since 2011.

The name is Satoshi Nakamoto. It appears as the author of the white paper, as the sender of the first emails about the project, and as the username on the forum where early Bitcoin was built. Everything else about the person or people behind the name is inference. Satoshi may have been one person. Satoshi may have been a small group working under one name. Satoshi may have been someone whose name appears in the history of cryptography, or someone nobody has ever heard of. The record does not settle it, and honest writing about Bitcoin says so plainly instead of picking a favorite candidate and presenting a guess as a fact.

This article keeps evidence and claims apart throughout. Dates, documents, and court rulings are stated as facts with their sources. Candidates are presented with the evidence for them and the evidence against them, and the gaps are named rather than filled in. That distinction matters more here than in most articles, because the history of this question is a history of confident claims that later collapsed.

What the Record Actually Shows

Before the candidates and the court cases, it helps to set out what is documented beyond reasonable dispute. The timeline below is the skeleton of the story, and every later section hangs on it.

Satoshi first appeared in public on 31 October 2008, when a paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System” was posted to the Cryptography Mailing List, a discussion list for cryptographers hosted at metzdowd.com. The list itself ran on the internet, whose own inventors are named and documented in our history of when the internet was invented, which makes the contrast with Satoshi’s anonymity all the sharper. The paper was signed “Satoshi Nakamoto,” with the email address [email protected]. It proposed a system for electronic cash that worked without banks or any other trusted third party, using a peer-to-peer network and a chain of proof-of-work records to prevent the same coin being spent twice.

The network itself went live on 3 January 2009, when Satoshi mined the first block, known as the genesis block. The first transfer of bitcoin between two people followed nine days later, on 12 January 2009, when Satoshi sent 10 bitcoin to Hal Finney, a cryptographer who had been one of the first people to download and run the software.

For the next two years Satoshi worked in public, writing code, answering questions on the BitcoinTalk forum, and exchanging emails with the small group of developers who gathered around the project. Then the public presence ended. Satoshi’s last post on the BitcoinTalk forum was on 12 December 2010, a technical note about a software release. Private emails to developers continued into the spring of 2011, and then they stopped too. The last known messages are dated April 2011. Nothing verified from Satoshi has appeared since.

That is the whole of the certain record in outline. Everything else in this article is either detail drawn from those documents or speculation that must be labeled as speculation.

The White Paper: 31 October 2008

The white paper is the founding document of Bitcoin, and it is also the best evidence we have about its author, because it is the one thing Satoshi certainly wrote. It is nine pages long, and it is still available to read in full from bitcoin.org, where it is presented as Satoshi Nakamoto’s original paper.

The paper opens with a problem. Commerce on the internet relied almost entirely on financial institutions acting as trusted third parties to process payments, and that trust created costs: transactions could be reversed, disputes needed mediation, and small casual payments were not practical. Satoshi proposed a system based on cryptographic proof instead of trust, in which any two willing parties could transact directly with each other without needing a trusted third party. The solution used a peer-to-peer network that timestamped transactions by hashing them into an ongoing chain of proof-of-work, forming a record that could not be changed without redoing the proof-of-work. The paper called this chain the basis for agreement about which transactions came first, which is what stops the same coin being spent twice.

The paper did not come out of nowhere. Its references section cites earlier work, and the citations are a map of the ideas Satoshi built on. Wei Dai’s “b-money” from 1998 is cited first. Adam Back’s Hashcash, a system for proving work to fight spam, from 2002, is cited for the proof-of-work idea. Work on timestamping digital documents by Stuart Haber and Scott Stornetta, from the early 1990s, is cited for the timestamp chain. Ralph Merkle’s 1980 paper on public key cryptosystems is cited for the tree structure used to organize transactions. These citations tell us Satoshi was well read in a small and specialized field, and that Bitcoin was a combination of existing ideas assembled into a working system rather than a single new invention dropped from the sky.

The paper also tells us something about its author by what it does not contain. It gives no real name, no institution, no address, and no biography. The author line is just the pseudonym and an email address at GMX, a free email service. The writing is in English, and it is careful, formal, and free of personal detail. Whoever wrote it wanted the ideas judged on their own, and wanted nothing known about themselves.

Two details in the paper are worth noting because they come up in the arguments about identity. First, the paper’s references show a familiarity with the cypherpunk movement, a loose group of cryptographers and programmers in the 1990s who believed cryptography could protect privacy and limit the power of institutions. Second, the paper’s author knew the prior attempts at digital cash well enough to explain why they had failed, and to borrow their best parts. That points to someone who had followed this field for years, not a newcomer.

If you want to understand what Bitcoin actually is, rather than who made it, our guide to what Bitcoin looks like explains the coins, the addresses, and the network in plain terms.

The Genesis Block: 3 January 2009

The white paper described a system. The genesis block started it. On 3 January 2009, Satoshi mined the first block of the Bitcoin blockchain, block zero. It carried a reward of 50 bitcoin, the first bitcoin ever created, and it carried a message.

The message was a line of text from that day’s newspaper: “The Times 03/Jan/2009 Chancellor on brink of second bailout for banks.” The Times is a British newspaper, and the headline referred to the British government preparing a second rescue package for banks during the financial crisis. The message was embedded in the data of the block, where it remains readable today by anyone who inspects the blockchain.

The message does two things. First, it works as a timestamp. Because it quotes a headline published that day, the block cannot have been created before 3 January 2009, which proves the network started when Satoshi said it did. Second, it is widely read as a comment on the banking system Bitcoin was designed to work without, although Satoshi never explained the choice in so many words, and any reading beyond the facts is interpretation rather than evidence.

The 50 bitcoin in the genesis block can never be spent. That is a quirk of how the first block was coded, and it means those first coins sit permanently unmoved. It is a small detail, but it has become a symbol of the story: the founder’s first coins were never used, and the founder never came back for them.

The genesis block also fixes the date Bitcoin began. Some people date Bitcoin to the white paper in October 2008, and some to the release of the software in January 2009, but 3 January 2009 is the date the network itself started running, and it is the date most histories use as Bitcoin’s birthday. If you are curious about the work that keeps the network running today, our explainer on whether you can still mine Bitcoin covers mining as it works now.

The First Transaction: Hal Finney

Nine days after the genesis block, on 12 January 2009, Satoshi sent 10 bitcoin to Hal Finney. The transfer is recorded in block 170 of the blockchain, and it was the first time bitcoin moved from one person to another. It was a test as much as a payment: Finney had downloaded the software on the day it was released and was one of the very few people running it. He later wrote that he had been running the software and that Satoshi sent him the coins as an experiment.

Finney matters to this story for two reasons. The first is that he was a respected cryptographer in his own right, and his early involvement shows that the first people to take Bitcoin seriously were not speculators but people who had worked on digital cash for years. Finney had built a system called reusable proofs of work in 2004, which was itself a step toward Bitcoin, and he was active on the cypherpunk mailing lists where the white paper first appeared. The second reason is that Finney became, after Satoshi disappeared, the most discussed candidate for the identity, and the evidence for and against him is a good example of how this kind of argument works. That evidence is examined below.

Finney died in 2014 from amyotrophic lateral sclerosis, known as ALS. He never claimed to be Satoshi. In forum posts and interviews he described himself as an early helper and a recipient of the first transaction, and he wrote openly about his illness and his hope that his body might be preserved by cryonics after his death. He denied being Satoshi, and the timing of his illness makes sustained secret authorship in the later years unlikely, though it does not rule out his involvement in the early work. The honest description is that Finney was close to Satoshi, was the first person to receive bitcoin, and was never shown to be Satoshi.

The Disappearance: 2010 to 2011

Satoshi’s withdrawal was gradual, not sudden, and that matters because it rules out some of the more dramatic theories. There was no final announcement and no farewell post. The public record simply thins out and then stops.

The last public post from Satoshi on the BitcoinTalk forum was on 12 December 2010. It was a technical note about version 0.3.19 of the software, describing limits added to reduce the risk of denial-of-service attacks. It contained no personal content and no hint that it would be the last post. Satoshi’s account on the forum had made 575 posts since it was created in November 2009, and then it went silent.

Behind the scenes, Satoshi was handing the project over. In late 2010, Gavin Andresen, a developer who had been contributing to the code, was given access to the source code repository and became the project’s lead maintainer in practice. In December 2010 Satoshi told another early contributor, Martti Malmi, that Andresen should be running things. The handover was deliberate and orderly.

The final messages came in April 2011. On 23 April 2011, Satoshi emailed Mike Hearn, a developer who had been corresponding with him about technical proposals, and closed with the words that he had moved on to other things and that the project was in good hands with Gavin and everyone. On 26 April 2011, Satoshi emailed Andresen directly, handing over the alert key used to send network-wide messages, and asking Andresen to stop presenting him as a mysterious shadowy figure, because the press turned that into an angle about pirate currency. Satoshi asked instead that the focus be the open source project and the developers contributing to it. No verified communication from Satoshi has been recorded since those April 2011 emails.

Two points in that ending deserve attention. First, Satoshi’s own words show that the anonymity was at least partly deliberate: he asked not to be treated as a mystery, which is a strange request from someone who had hidden their identity so carefully, and it suggests he wanted the project, not the person, to carry the attention. Second, the withdrawal was complete. Satoshi did not keep a public profile, did not give interviews, and did not claim credit as Bitcoin grew. Whoever Satoshi was, they walked away from the most valuable creation of their life and never came back to claim it.

The Clues People Argue Over

With no name and no face, people have spent more than a decade arguing over clues. Some of the clues are real, in the sense that they come from Satoshi’s own writing. All of them are weaker than they first appear, because a careful person can plant or fake almost any of them. Here are the main ones, with their limits stated plainly.

The first clue is the profile. Satoshi had a profile on the P2P Foundation forum, a site for discussion of peer-to-peer ideas, which described the account holder as a man, aged 37, living in Japan. Almost nobody takes this at face value. The writing in the white paper and the forum posts is fluent English with no trace of a Japanese speaker’s errors, and the software was documented in English, not Japanese. The name itself, Satoshi Nakamoto, is a plausible Japanese name, but it may have been chosen precisely because it sounds like a real name while revealing nothing. The profile is evidence of what Satoshi chose to say about himself, not evidence of who he was.

The second clue is language. Satoshi’s writing used British spelling in places, with words spelled the British way and dates written in the British day-first format, as in the genesis block message “03/Jan/2009.” Some researchers have argued this points to a British person or someone from a Commonwealth country. Others note that Satoshi also used American spelling at times, and that a careful writer can switch conventions deliberately. The language evidence is suggestive, not decisive, and it is compatible with several candidates and with a group.

The third clue is timing. Researchers have analyzed the timestamps of Satoshi’s forum posts and emails and found that they cluster in hours that fit a person living in the United Kingdom or in the eastern United States, and that they go quiet on certain days. But the sample is small, the timestamps can be affected by time zones in the software, and a person working unusual hours or using a virtual private network can produce any pattern. Timing analysis has produced several different answers depending on who runs it, which is a sign that it should be treated as a weak clue.

The fourth clue is the code. The first Bitcoin software was written in C++, and its style has been studied by programmers looking for a fingerprint. Some have argued the code shows the hand of a single experienced developer, while others have argued it shows more than one hand, with parts written at different levels of skill. The code also contains comments and quirks, including the reversed Times headline hidden in an early version. Code style analysis is a real technique, but it is not a fingerprint in the forensic sense, and it has not produced a match that experts agree on.

The fifth clue is the knowledge. Satoshi knew cryptography, economics, game theory, and distributed systems, and knew the history of digital cash attempts going back to the 1990s. That narrows the field to a small group of people, but the group is not that small: the cypherpunk mailing lists had hundreds of subscribers, and the ideas in the white paper were discussed openly for years. Knowing the field is necessary to have written the paper, but it is not enough to identify the author.

None of these clues, alone or together, identifies a person. That is why the candidates below remain candidates rather than answers.

The Candidates, One by One

Over the years, many names have been put forward. Most were suggested by journalists or researchers working from circumstantial evidence. A few were self-claims. None has been proved. Here are the main ones, in the order they entered the public conversation.

Hal Finney is the strongest candidate on proximity and the weakest on proof. He received the first transaction, he corresponded with Satoshi from the earliest days, he had the technical background, and he lived in California, which fits some of the timing analysis. Against him: he denied it, his writing style has been compared with Satoshi’s and found different by several analysts, and his declining health from 2009 onward makes it hard to square with Satoshi’s sustained output through 2010. Finney himself wrote that he had exchanged emails with Satoshi and that he thought he was dealing with ‘a young man of Japanese ancestry who was very smart and sincere’, which is an odd thing to write if he was describing himself. The case for Finney rests on closeness, not on a match, and closeness is not identity.

Nick Szabo is the strongest candidate on ideas. Szabo proposed a system called bit gold in 1998, which is one of the closest predecessors to Bitcoin, and his writing on the history of money and on smart contracts shaped the thinking of the whole field. Researchers have noted similarities between Szabo’s writing style and Satoshi’s, and Szabo’s knowledge of the subject matches the white paper’s demands exactly. Against him: Szabo has denied it repeatedly, and the stylistic comparisons have been challenged by other researchers who found the match weaker than claimed. Szabo also worked openly under his own name throughout the period when Satoshi was active, which would have required a double life of unusual discipline. The case for Szabo is a case about ideas, and ideas can be shared without identity being shared.

Adam Back is a candidate because of Hashcash, which the white paper cites, and because Back was active on the cryptography mailing lists and corresponded with Satoshi. Back has denied being Satoshi, and the main evidence for him is that he was in the right place with the right knowledge. That is true of many people in this field, and it is not enough on its own.

Wei Dai is a candidate because the white paper cites b-money first among its references, and because Dai was a respected figure on the cypherpunk lists. Dai has denied being Satoshi, and there is no positive evidence linking him to the authorship beyond the citation, which is a sign of influence, not identity.

Dorian Nakamoto is the most famous false identification, and the most instructive. In March 2014, Newsweek published a cover story titled “The Face Behind Bitcoin,” identifying a 64-year-old Japanese-American man named Dorian Satoshi Nakamoto, living in California, as the creator of Bitcoin. The story rested largely on a misunderstood remark: asked about Bitcoin, Dorian said he was no longer involved in that and could not discuss it, which the reporter took as a confession. Dorian later explained he had thought the question was about his earlier classified engineering work for Citibank and the military, not about cryptocurrency. He formally denied any connection to Bitcoin in an interview with the Associated Press, saying he had nothing to do with it and had never heard of Bitcoin until the reporter contacted him. A few days after the Newsweek story, a message appeared on the P2P Foundation forum under Satoshi’s old account reading “I am not Dorian Nakamoto.” That account had been compromised in 2014, so the message cannot be treated as verified from Satoshi, but the denial from Dorian himself is clear, and no evidence has ever connected him to the project. The episode is a warning about what happens when a coincidence of names is treated as evidence.

Craig Wright is the only candidate who claimed the title persistently and pursued it in court, and his claim is the only one a court has ruled on. Wright, an Australian computer scientist, began claiming in 2015 and 2016 that he was Satoshi, and he brought legal actions against developers and companies on that basis. The claim is dealt with in its own section below, because the court record is the strongest evidence in this whole story, and it runs against Wright.

Peter Todd is the most recent candidate, named in the HBO documentary “Money Electric: The Bitcoin Mystery,” released in October 2024. The film’s director, Cullen Hoback, argued that Todd, a Bitcoin developer and cryptography consultant, was Satoshi, based on forum posts and circumstantial connections. Todd denied it immediately, telling the BBC he was not Satoshi and calling the evidence ludicrous, and the Bitcoin developer community largely dismissed the claim. A basic problem with it is timing: Todd became involved with Bitcoin around 2011, after Satoshi had already left. The documentary’s claim has not been accepted by researchers, and Todd has said the attention put his safety at risk.

Other names surface from time to time, including the late cryptographer Len Sassaman, the programmer Gavin Andresen himself, and the entrepreneur Elon Musk, who has denied it. Each of these has a thin circumstantial case and a clear denial or a clear timeline problem, and none has produced the kind of proof the field would accept. The pattern across all of them is the same: a real connection to the early Bitcoin world, a suggestive detail or two, and no decisive evidence.

The Court Case That Settled One Claim

The one claim that has been tested in court is Craig Wright’s, and the result is unambiguous. In 2021, the Crypto Open Patent Alliance, known as COPA, an industry group that includes companies such as Coinbase and Block, brought a case in the High Court of England and Wales asking the court to decide whether Wright was Satoshi Nakamoto. Wright had claimed the identity since 2015 and had used it to bring copyright and other claims against Bitcoin developers and businesses. The trial ran from February into March 2024 before Mr Justice Mellor.

On 14 March 2024, at the end of closing submissions, the judge announced his conclusion: the evidence was overwhelming, and he would declare that Wright was not Satoshi Nakamoto. The written judgment followed on 20 May 2024, in the case known as COPA v Wright, neutral citation [2024] EWHC 1198 (Ch). It made four declarations: that Wright was not the author of the Bitcoin white paper, that he was not the person who adopted or operated under the pseudonym Satoshi Nakamoto between 2008 and 2011, that he was not the person who created the Bitcoin system, and that he was not the author of the initial versions of the Bitcoin software. The judge found that Wright had lied to the court extensively and repeatedly, that he had forged documents to support his claim, and that he had used the courts as a vehicle for fraud.

Wright was later found in contempt of court in December 2024 for continuing to bring claims based on the identity, and was given a 12-month prison sentence, suspended for two years.

It is important to state precisely what the ruling does and does not do. It decides that Craig Wright is not Satoshi Nakamoto. It does not decide who Satoshi Nakamoto is. A finding that one named person is not Satoshi narrows the field by exactly one, and the identity behind the pseudonym remains unknown. That is how the judgment should be reported, and how this article reports it.

The case also set a standard for what proof would look like. The Bitcoin community has long held that the only convincing proof of being Satoshi would be cryptographic: signing a message with the private keys that control the earliest mined coins, or moving some of those coins. Wright never produced such proof, and the documents he offered instead were found to be forged. Any future claimant will be measured against the same standard, and so far nobody has met it.

The Unmoved Coins

One more piece of evidence is often cited, and it deserves a careful hearing: the coins Satoshi mined have never moved. Researchers who have studied the pattern of early mining estimate that Satoshi mined roughly one million bitcoin in the first year of the network, using a distinctive pattern of blocks that stands out from other early miners. That figure is an estimate, not a count from a known wallet, and different researchers have produced different numbers. What is not in doubt is that the earliest mined coins, including the reward from the genesis block, have never been spent. They sit in their original addresses, untouched since 2009 and 2010.

That stillness is evidence of a kind. The protocol caps total supply at 21 million bitcoin, so the early mined coins are a fixed share of a fixed total. If Satoshi were alive, active, and interested in the money, the natural thing would be to spend some of it, or at least to move it. That it has never moved suggests three possibilities, none of which can be proved: that Satoshi is dead, that Satoshi lost access to the keys, or that Satoshi deliberately chose never to touch the coins, to preserve the anonymity and the decentralization of the project. The third possibility is the one most often favored by people who study the story, because it fits with everything else Satoshi did, but it is an interpretation, and it should be labeled as one.

The unmoved coins also matter for a practical reason. Because they have never moved, they cannot be used to identify Satoshi, and because no claimant has ever moved them or signed with their keys, no claimant has ever passed the test the community set. The coins are both the largest unclaimed fortune in the story and the strongest reason to doubt every claim made about it.

Why the Anonymity Matters, and Why It May Not

There is a real argument about whether Satoshi’s identity matters at all, and it is worth taking seriously, because it shapes how you read the whole story.

The argument that it matters runs like this. Bitcoin was designed to work without trusted authorities, and its founder’s anonymity is part of that design. If Satoshi were known, that person would become a target for governments, for criminals, and for the press, and would be treated as a leader or a spokesperson whether they wanted the role or not. The anonymity also protects the project from the founder’s flaws: there is no biography to attack, no past statement to weaponize, and no single person whose arrest or death could be presented as the end of Bitcoin. On this view, Satoshi’s disappearance was not an accident but the final step in making Bitcoin genuinely leaderless.

The argument that it does not matter runs the other way. Bitcoin works because of its code, its network, and its rules, not because of its founder. The software is open source, which means anyone can read it, copy it, and propose changes. Changes are made by a loose group of volunteer developers and are adopted only when the people running the network agree to run the new version. No single person controls it, and Satoshi’s opinion, if it were known, would carry no formal weight. The network has run for more than seventeen years without its founder, and it does not need the founder to return. On this view, the identity question is a human curiosity, not a technical one, and the answer would change nothing about how Bitcoin works.

Both arguments have force, and they are not really in conflict. The identity matters for history and for understanding how Bitcoin began, and it does not matter for how Bitcoin works today. That is why the question keeps being asked and why the answer, “Satoshi Nakamoto, identity unknown,” is both unsatisfying and accurate.

There is also a simpler reason the anonymity matters to readers. People want a story with a person in it, and Bitcoin’s story has a person-shaped hole at its center. That hole has been filled, over and over, with guesses, and the guesses have caused real harm, most visibly to Dorian Nakamoto, an innocent man whose life was disrupted by a magazine cover. The responsible way to write about this question is to leave the hole empty where the evidence leaves it empty, and to say so.

How to Judge the Next Claim

New claims that someone is Satoshi appear regularly, and they will keep appearing. Readers can judge them with a short checklist drawn from the history above.

First, ask for cryptographic proof. The only evidence the Bitcoin community treats as decisive is a message signed with the private keys of the earliest Bitcoin addresses, or a movement of the earliest mined coins. A document, a story, or a stylistic match is not proof. Craig Wright offered documents, and they were found to be forged.

Second, check the timeline. Satoshi was active from 2008 to April 2011 and then vanished. A candidate who only became involved with Bitcoin after 2011, as Peter Todd did, has a basic timeline problem. A candidate whose public life is fully documented through those years would have had to lead a double life.

Third, watch for the denial. Almost every serious candidate has denied being Satoshi, often firmly and repeatedly. A denial is not proof of innocence on its own, since the real Satoshi would also deny it, but a pattern of denials from people with nothing to gain by lying should carry weight.

Fourth, ask who benefits. Claims about Satoshi have been used to support lawsuits, to sell books and films, and to gain attention. That does not make a claim false, but it is a reason to demand stronger evidence than a good story.

Fifth, remember the court record. Any claim that Craig Wright is Satoshi now runs directly against a High Court judgment, and repeating it as fact would be repeating something a court has found to be false.

The safest summary, and the one this article stands behind, is the one in the Short Answer: Bitcoin’s founder is Satoshi Nakamoto, and nobody has proved who Satoshi Nakamoto is. Until someone signs with the early keys, that is where the matter rests.

FAQ

Who is the founder of Bitcoin?

Bitcoin was created by Satoshi Nakamoto, a pseudonym. The real identity of the person or group behind the name has never been established. Satoshi published the white paper in October 2008, launched the network in January 2009, and disappeared from public view in 2010 and 2011.

Is Satoshi Nakamoto a real person?

Satoshi Nakamoto is a real name in the sense that it is attached to real documents, real code, and real messages. Whether it belongs to one person, a group of people, or a person using a false name is unknown. The P2P Foundation profile linked to the name claimed a 37-year-old man living in Japan, but that claim has never been verified and is widely doubted.

Did Craig Wright create Bitcoin?

No. In March 2024, the High Court of England and Wales ruled in COPA v Wright that Craig Wright is not Satoshi Nakamoto, did not write the Bitcoin white paper, did not create the Bitcoin system, and did not write the original Bitcoin software. The court found that Wright had lied and forged documents to support his claim.

Was Hal Finney Satoshi Nakamoto?

There is no proof that he was. Finney was the first person to receive bitcoin, sent 10 bitcoin by Satoshi on 12 January 2009, and he was a respected cryptographer who helped the early project. He denied being Satoshi. The evidence for Finney is circumstantial, based on his closeness to the project, and several analysts have found his writing style differs from Satoshi’s.

How much bitcoin does Satoshi own?

The figure most often cited is roughly one million bitcoin, mined in the early days of the network. That is an estimate produced by researchers studying the pattern of early mining, not a confirmed count from a known wallet, and different researchers have given different figures. What is certain is that the earliest mined coins have never been spent or moved.

Why did Satoshi Nakamoto disappear?

Nobody knows for certain, because Satoshi never explained it. The last messages, in April 2011, said only that Satoshi had moved on to other things and that the project was in good hands with Gavin Andresen. The most common reading is that Satoshi wanted Bitcoin to stand on its own without a founder, but that is an interpretation, not a documented reason. Theories involving intelligence agencies or threats are speculation and run against the timeline of the actual messages.

Is Bitcoin still run by its founder?

No. Bitcoin has no founder in charge of it today, and it has had none since 2011. The software is open source, maintained by volunteer developers, and changes take effect only when the people running the network choose to adopt them. The network has run without Satoshi for more than seventeen years.
