Who is Satoshi Nakamoto? What we know about him in 2026

On April 8, 2026, The New York Times published a 12,000-word investigation by John Carreyrou, the journalist who once buried Theranos. The conclusion: the real Satoshi Nakamoto is Adam Back, CEO of Blockstream and a British cryptographer. Carreyrou says his confidence is “between 99.5% and 100%”. Back responded with a post on X: “I am not Satoshi.” The second storyline: the documentary Finding Satoshi — four years of investigation, interviews with Michael Saylor, Bill Gates, Phil Zimmermann. The authors promise a definitive answer.

Sixteen years after the whitepaper, we still don’t know who created Bitcoin. And it looks like we never will. In this article I break down what’s actually known as of April 2026, who the main suspects are, why none of them are Satoshi with 100% certainty, and why this uncertainty is probably better than any answer.

What we know for certain about Satoshi

Facts without speculation are very few.

On August 18, 2008, the bitcoin.org domain was registered. The registration was made through anonymousspeech.com — a Japanese anonymous registration service that accepted payment by cash in the mail and did not require real identity data. The WHOIS record lists only a dummy Tokyo address (1-3-3 Sakura House) and the service’s own contact email. The real name of the registrant has never been revealed. A detail WHOIS-archive researchers only noticed in 2022: a day earlier, on August 17, someone bought netcoin.org through the same service. Satoshi was likely deciding between two names. In May 2011, after Satoshi had stepped away from the project, control of bitcoin.org passed to Finnish developer Martti Malmi (handle Sirius), one of the first active members of the community.

On October 31, 2008, a post appeared on the metzdowd.com cryptography mailing list from a user named Satoshi Nakamoto. Attached was a nine-page PDF: Bitcoin: A Peer-to-Peer Electronic Cash System. This is the whitepaper that started everything.

On January 3, 2009, Satoshi launched the network and mined the first block, now known as the Genesis Block. The coinbase transaction contains the headline from that day’s Times: “The Times 03/Jan/2009 Chancellor on brink of second bailout for banks”. This isn’t an easter egg — it’s a political statement about why Bitcoin is needed.

On January 12, 2009, the first peer-to-peer transaction in Bitcoin history took place: Satoshi sent 10 BTC to cryptographer Hal Finney. It’s the only time coins from Satoshi’s addresses have ever moved.

Over the next two years Satoshi actively developed the code and answered questions: first on SourceForge, then on bitcoin.org/smf, later on forum.bitcoin.org and on cryptography mailing lists. His main collaborator during this period was Martti Malmi (handle Sirius), a Finnish developer. Malmi emailed Satoshi in May 2009 after reading the whitepaper and soon became the second active contributor to the project: running hosting, developing the website, moderating the forum.

Satoshi himself registered the bitcointalk.org domain on November 17, 2009, but the forum only migrated to it in July 2011, by which point Satoshi had already disappeared. Control of the domain eventually passed to Malmi, who still owns it today. The forum is administered by theymos (Michael Marquardt), who took over moderation in 2012.

Satoshi’s writing style is British English: two spaces after a period, spellings like “colour” and “favour”, distinctive hyphenation logic. The time zones of his posts point to Europe, even though Satoshi claimed residence in Japan and used a Japanese name.

Everything else — the name, the country, the age, the number of people behind the pseudonym — is just theory.

The 1.1 million BTC that haven’t moved since 2010

Satoshi mined alone for the first 12-18 months. When Bitcoin launched, there was virtually no competition on the network: a single CPU could mine new blocks with a reward of 50 BTC each. Satoshi configured his hardware so as not to dominate completely, leaving gaps where others could find blocks.

In 2013, Argentine cryptographer Sergio Demian Lerner noticed a distinctive fingerprint in the early blocks left by a single miner. The hardware filled the ExtraNonce service field in a non-standard way and mined several threads in parallel — likely across 50 CPUs simultaneously, something no one else on the network at the time was doing. Lerner called this entity Patoshi (a blend of “pattern” and “Satoshi”) and deliberately chose that name: this is someone who looks like Satoshi, but there is no cryptographic proof that Patoshi and Satoshi are the same person. According to Lerner’s estimates and subsequent refinements, roughly 22,000 addresses are linked to Patoshi, holding around 1.1 million BTC.

At April 2026 prices, that’s about $79 billion. If Satoshi is one person, he ranks among the richest people on the planet. If the coins ever move, it will be an event of geopolitical scale.

But they don’t move. Not a single transaction has occurred from these addresses since January 2010, apart from the same 10 BTC Satoshi sent to Hal Finney in January 2009. Sixteen years of absolute on-chain silence.

There are three possibilities:

• Satoshi is dead, and the private keys are lost forever.
• Satoshi is alive, the keys are intact, but he has consciously decided never to touch these coins so as not to undermine the decentralization narrative.
• The keys are with someone who is waiting, or who will never dare to sell, because any movement from these addresses would instantly crash the market.

Practically speaking, the Bitcoin market treats these coins as “burned”. They exist in the supply formally, but no one factors them into market models as live liquidity. This reduces the effective supply by roughly 5% and reinforces Bitcoin’s scarcity narrative.

The NYT version (April 2026): Adam Back as the prime suspect

John Carreyrou is not a random journalist. He’s the author of Bad Blood, who dismantled Elizabeth Holmes’ Theranos in 2015 and won a Pulitzer for it. When he spent 18 months searching for Satoshi and then declared he was 99.5-100% confident, the topic gained weight.

His method is stylometric analysis. Carreyrou, along with NYT AI editor Dylan Friedman, assembled an archive of 34,000 participants from cryptography mailing lists from 1992-2008 and from bitcointalk.org posts. They ran these texts through a model that searched for the distinctive fingerprints of Satoshi’s style.

The key finding: hyphens. Satoshi made 325 specific errors in the hyphenation of compound words. In Adam Back’s posts, they found 67 matches. The next candidate produced 38. In addition, Back shared British spellings (colour, favour, optimisation), a habit of using two spaces after a period, and similar linguistic patterns.

Next, the biography. Adam Back, 55, British cryptographer. In 1997 he invented Hashcash, the proof-of-work system that Satoshi directly cited in the whitepaper as the basis of the mining mechanism. He actively wrote to cryptography mailing lists from 1992. Then, during the period Satoshi was most active (2009-2010), Back went silent on those same mailing lists. He returned to public view roughly when Satoshi disappeared. Back is now CEO of Blockstream and runs a company that accumulates BTC on its balance sheet.

Back denies all of this. After the NYT publication, he wrote on X: “I am not Satoshi. I was focused early on the positive societal implications of cryptography, privacy, and electronic cash. Hence my interest from around 1992, which led to Hashcash and other ideas.” He showed letters from 2008 in which Satoshi addresses him as an outsider, just to verify a citation for the whitepaper. Carreyrou suspects Back could have written these letters to himself as cover. Back calls this paranoia.

The weak points of the theory are there, and they’re serious:

• Carreyrou’s own linguist, Florian Cafiero (the same one who once helped NYT identify QAnon authors), called his results “inconclusive”. Hal Finney, the deceased cryptographer, nearly tied with Back at the top of the list on stylometry.
• There were several dozen British cryptographers of that generation with similar writing styles and comparable biographies. Double spaces and British spellings are markers of an entire layer of academics, not an individual signature.
• Most importantly: no one, neither Carreyrou nor Back, has presented cryptographic proof. A private-key signature from any of Satoshi’s 22,000 addresses would close the question in 30 seconds. No such signature has ever appeared from anyone.

Fortune, responding to the investigation, wrote that Carreyrou is clearly suffering from confirmation bias: by the same logic Nick Szabo fits just as well — his initials even phonetically match “Satoshi Nakamoto” — but Carreyrou simply dismissed him.

Other candidates suspected for years

Hal Finney

One of the strongest hypotheses by weight of evidence, despite the fact that Finney died in 2014 from amyotrophic lateral sclerosis (ALS). He worked at PGP Corporation, was one of the first developers of cryptographic systems, and a key participant in the cypherpunks mailing lists. In January 2009, Finney was the first person in the world to receive bitcoin — those same 10 BTC from Satoshi. He ran the second node on the network.

Forbes journalist Andy Greenberg commissioned stylometric analysis back in 2014 and got the closest match with Finney. Additional detail: Finney lived in Temple City, California, a few blocks from a man whose real name was Dorian Satoshi Nakamoto (the one Newsweek would later name as Satoshi).

Against: Finney publicly corresponded with Satoshi as a third party; his family showed the letters. If he and Satoshi are the same person, he staged a very elaborate, long-running performance. Also, Finney’s BTC wallet doesn’t match the Patoshi cluster.

As of 2026: Carreyrou’s stylometry placed him almost level with Back. If Finney did create Bitcoin, the keys are now either with his family or lost. The family has always publicly denied that he was Satoshi.

Nick Szabo

American cryptographer and lawyer, author of the bit gold concept (1998-2005), a decentralized digital currency ideologically very similar to Bitcoin. He also introduced the concept of smart contracts back in 1994. The technical foundation and philosophy of his work are so close to the whitepaper that in 2015 the NYT itself wrote that Szabo was the most likely candidate.

Szabo systematically denies it. In 2011 he deleted a post about bit gold from his blog, containing references dated 2008 that could be interpreted as preparation for the Bitcoin release. He never explained why.

As of 2026: Fortune, responding to the NYT article about Back, wrote directly that Szabo still looks more logical. The initials “Nick Szabo” mirrored give “S.N.”, as in Satoshi Nakamoto. This is, of course, speculation, but in this topic such details carry weight.

Peter Todd (the HBO 2024 version)

The HBO documentary Money Electric: The Bitcoin Mystery (October 2024, dir. Cullen Hoback) named Canadian Bitcoin developer Peter Todd as Satoshi. The basis: in 2010, a day after registering on bitcointalk.org, Todd corrected a technical error in one of Satoshi’s later posts — and corrected it exactly as Satoshi himself would have, then disappeared from the forum at the same time as Satoshi.

Hoback’s case collapsed almost immediately. Todd publicly stated: “For the record — I am not Satoshi. Cullen is grasping at straws. These are all coincidences, and that’s the hallmark of conspiratorial thinking.” The crypto community didn’t accept the theory; four early crypto developers publicly said that Todd, by the level of his code and his character, simply doesn’t fit.

After the film was released, Todd started receiving messages demanding to “borrow a million,” along with veiled threats.

Dorian Nakamoto

A separate case of why such investigations are dangerous. In March 2014, Newsweek ran a cover story titled “The Face Behind Bitcoin”. Journalist Leah McGrath Goodman found a man in Temple City whose birth name really was Satoshi Nakamoto — a 65-year-old Japanese-American physicist-engineer who had once worked on classified defense projects.

The only “proof” was a sentence on his doorstep: “I am no longer involved in that and cannot discuss it.” Dorian later explained that he was talking about the defense projects, not Bitcoin, and that he first heard about cryptocurrency from the journalist. He had no programming experience in cryptography, had never posted on cypherpunks mailing lists, and didn’t have the technical knowledge to create Bitcoin.

After the cover story, journalists staged a car chase after him through Los Angeles. At the same time, the real Satoshi account on bitcointalk.org posted its only message after 2011: “I am not Dorian Nakamoto.” This is the last known public signal from the real Satoshi.

What saved Newsweek from a humiliating failure in the Dorian case was only that Dorian did not sue. The crypto community raised a relief fund for him of 102 BTC.

Craig Wright. A separate case. Why the court proved he is not Satoshi

A topic that cluttered the media for a long time is officially closed.

Australian computer scientist Craig Wright publicly claimed in 2016 that he was Satoshi Nakamoto. He showed a video with “cryptographic proof” that experts dismantled within hours as a forgery. Despite this, Wright spent another eight years running through courts, suing Bitcoin developers over “intellectual property rights to Bitcoin”, suing anyone who said he wasn’t Satoshi, and launching his own fork, Bitcoin SV.

In March 2024, the UK High Court ruled in the Crypto Open Patent Alliance (COPA) case: Wright is not Satoshi. Judge James Mellor published a detailed ruling in May, stating directly that Wright “lied to the court systematically and repeatedly”, and that the documents submitted as evidence were forgeries.

In December 2024, Wright received a one-year suspended sentence for contempt of court: after a direct court order not to file new lawsuits, he filed a £900 billion lawsuit against Block Inc. Jack Dorsey’s company, and against Bitcoin Core developers. He didn’t appear at the London hearing, joining remotely from Asia. The court additionally ordered Wright to pay COPA £145,000 in legal costs.

As of 2026, the Craig Wright topic is no longer discussed in serious crypto media. The only reason to mention him in an article about Satoshi is to warn people who might google and stumble on old materials. He is not Satoshi, and that has been established by the courts.

Finding Satoshi: another attempt to close the question

The authors of Finding Satoshi took an unconventional route: no HBO, no streaming platforms. The film is sold directly through findingsatoshi.com for $14.99, with no distributors. Tucker Tooley (producer of The Fighter, Den of Thieves) deliberately chose this format, telling TheWrap: “We’re telling the story of Bitcoin, which removed intermediaries from finance. It’s only logical to remove intermediaries from distribution too.”

The lineup is strong. Directed by Matthew Miele and Tucker Tooley himself. The investigation was conducted over four years by journalist William Cohan (former M&A banker at Lazard and Merrill Lynch, author of Money and Power and House of Cards) and private investigator Tyler Maroney of Quest Research & Investigations. Maroney has worked on a range of complex criminal and civil cases in the US.

Interviews include: Michael Saylor, Bill Gates, Fred Ehrsam (Coinbase), Joseph Lubin (Ethereum), Phil Zimmermann (PGP), Bram Cohen (BitTorrent), Gary Gensler, Kara Swisher, and Kathleen Puckett, a former FBI behavioral analyst who worked on identifying the Unabomber.

Brian Armstrong, CEO of Coinbase, received an early screening and publicly stated: “This is the most thoroughly researched treatment of the topic I’ve seen. I suspect you’ve arrived at the right answer.” Coinbase is giving its users 24-hour early access to the film starting April 21.

Who the authors ultimately name is, as of this writing, not publicly known. Polymarket opened a betting market “Adam Back confirmed to be Satoshi?” on April 10, and Back is currently leading. This is an indirect signal that the market expects the film to go in the same direction as the NYT.

But it’s worth remembering: in 2024, an HBO documentary with the same level of marketing and confidence named Peter Todd. Within a week of release, the theory was refuted by the crypto community itself. Four years of investigation and a star-studded list of interviewees don’t guarantee that Finding Satoshi won’t repeat that fate.

Brief summary

As of April 2026, the strongest hypotheses by weight of evidence are Adam Back, Nick Szabo, and Hal Finney (posthumously). None of them is cryptographically confirmed. Without a private-key signature from Satoshi’s addresses, any investigation remains a construction of patterns from indirect evidence.

1.1 million BTC haven’t moved for sixteen years, and this is a more reliable signal about Satoshi’s fate than stylometry. If those coins move, the question will close instantly, but there are no signs of that for now.

The main thing to remember: the unknown identity of Bitcoin’s creator is not a bug, but an architectural property of the project. It protects the network from any single person being able to influence it politically or legally. As long as Satoshi stays silent, Bitcoin is decentralized by default. That may have been his final design choice.
