Who Is Satoshi Nakamoto? Candidates, Evidence and His Bitcoin Holdings

Updated on October 22, 2026: completely rewritten with the London High Court ruling against Craig Wright, the New York Times investigation into Adam Back, new estimates of Satoshi's bitcoin holdings and the BIP-361 debate. The previous version predated the 2024 court ruling and still described Craig Wright's claim as unresolved.

Satoshi Nakamoto is the pseudonym of the person or group who published the Bitcoin white paper on October 31, 2008 and launched the network on January 3, 2009. Who is behind the name has never been proven: nobody has ever produced a publicly verifiable signature with a key from the earliest blocks, and the only person who made the claim in court, Craig Wright, was ruled not to be Satoshi by the High Court in London in 2024. Satoshi stepped away in April 2011 and is believed to hold around 1.1 million bitcoin that have barely been touched since they were mined in 2009 and 2010.

This guide sets out what is actually established about the inventor of Bitcoin, the first cryptocurrency, which names keep coming up, what speaks for and against each of them, and why Satoshi's coins are back on developers' agendas.

Satoshi Nakamoto: the key facts

• October 31, 2008: Satoshi Nakamoto sends the nine-page white paper "Bitcoin: A Peer-to-Peer Electronic Cash System" to a cryptography mailing list.
• January 3, 2009: The first block of the Bitcoin blockchain carries a headline from The Times of London about a second bank bailout.
• April 23, 2011: In the last known email, Satoshi writes that he has moved on to other things.
• Around 1.1 million bitcoin: That is the common estimate of Satoshi's holdings, about 5.5 percent of the 20.10 million bitcoin in circulation.
• May 20, 2024: The High Court in London sets out in writing why Craig Wright is not Satoshi Nakamoto and did not write the white paper.
• April 8, 2026: The New York Times names Adam Back as the most likely candidate, and Back denies it the same day.

Satoshi Nakamoto from 2008 to 2011: what is on the record

The solid evidence is what Satoshi left behind: emails, forum posts, code and entries in the blockchain. Every item in the table can be checked in public archives or directly in the blocks.

The line in the first block reads "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks". It proves the block cannot have been created before that day, and it is still read as a comment on the financial crisis. In the white paper Satoshi describes a payment system with no bank in the middle, secured by computing work, the principle known today as bitcoin mining.

On April 23, 2011, Satoshi wrote to Mike Hearn "I've moved on to other things" and added that the project was in good hands with Gavin Andresen and the other developers. Nothing that can be clearly attributed to that address followed. A post reading "I am not Dorian Nakamoto" on the old P2P Foundation profile in March 2014 cannot be verified; the same account was hacked in September 2014. The only self-description is in that profile: it listed a birth date of April 5, 1975 and Japan as the place of residence, neither of them backed by any evidence.

Who is Satoshi Nakamoto? The best-known candidates

Seven names come up again and again. There is no proof for any of them, there is a court ruling against one, and every living candidate has denied being Satoshi. The table separates what is documented from what speaks against each theory.

Hal Finney and Nick Szabo: the early favourites

Hal Finney was the first person besides Satoshi to run Bitcoin and for a long time the most obvious candidate. In his look back, "Bitcoin and me" from March 2013, he describes Satoshi as a counterpart he exchanged emails with about bugs in the code. In 2023 developer Jameson Lopp matched the timing of a running race in Santa Barbara against Satoshi's emails: Finney was on the course for about 78 minutes on April 18, 2009, while Satoshi was writing to Mike Hearn. Finney died of ALS in August 2014.

Years before Bitcoin, Nick Szabo described a scarce digital currency based on computing work with bit gold. In 2014 forensic linguists at Aston University compared the white paper with texts by eleven candidates and landed on him, as CoinDesk reported at the time. A style comparison shows similarity, not authorship, and Szabo has rejected any role as Satoshi.

Adam Back and the New York Times investigation

On April 8, 2026, the New York Times published an investigation by reporter John Carreyrou, who after a year and a half of work considers Adam Back the most likely candidate. Back is the chief executive of Blockstream and the inventor of Hashcash, an early proof-of-work scheme the white paper refers to. He pushed back the same day with the words "I am not Satoshi", as Decrypt documented. Back points to emails from August 2008 in which Satoshi asked him for the correct citation before publishing.

Craig Wright and the High Court ruling

Craig Wright is the only person who has actively claimed to be Satoshi, and he fought for it in court. At the end of the trial on March 14, 2024, Mr Justice James Mellor declared that Wright did not write the white paper, did not operate under the pseudonym and did not create Bitcoin. The written judgment of May 20, 2024 records that Wright lied to the court extensively and forged documents to support his claim. In December 2024 he received a twelve-month suspended prison sentence for contempt of court after filing another Bitcoin-related claim in breach of a court order.

Len Sassaman, Peter Todd and Dorian Nakamoto

Before the HBO documentary, most bettors on Polymarket backed Len Sassaman, because his death came so soon after Satoshi's withdrawal. His widow Meredith Patterson told DL News that he was not Satoshi. Cullen Hoback's film then named Canadian developer Peter Todd, based largely on a forum post from 2010. Todd rejects the claim. Dorian Nakamoto, an engineer from California, dismissed Newsweek's story of March 2014 straight away, as TechCrunch reported at the time. Ripple's chief technology officer David Schwartz shows how quickly new names appear: after speculation in May 2024 he called the idea "not true, but plausible" and said he only came across Bitcoin in 2011. The post below is one example of that speculation.

How Satoshi Nakamoto could prove his identity

Proof would be simple and publicly verifiable: a message signed with the private key of an address from the earliest blocks. Satoshi demonstrably moved the coins from block 9 himself when he sent Hal Finney the first 10 bitcoin in block 170. Whoever holds that key can sign any message, and anyone can check the signature in seconds.

That is exactly where Craig Wright failed: his demonstrations in 2016 took place in a small circle, and he never produced a valid, publicly verifiable signature. Our view: until someone signs in that way, every attribution remains a chain of circumstantial evidence, however long it is. For more on Satoshi's early correspondence, see our report on the emails published by early developer Martti Malmi.

How many bitcoin does Satoshi Nakamoto own?

The usual figure is around 1.1 million bitcoin, but it is not certain. Satoshi never disclosed any addresses, so the estimate rests on a pattern in the early blocks. Depending on how strictly that pattern is read, the holdings range from just under 0.9 million to around 1.17 million bitcoin.

In 2013, computer scientist Sergio Demian Lerner found a signature in the random values of the first blocks that points to a single, very early miner. He called it "Patoshi". In a follow-up analysis in 2019 he attributed around 22,000 blocks with a combined total of close to 1.1 million bitcoin to this miner, 99.9 percent of which have never moved. The analytics firm Bitquery rebuilt the pattern from raw data in 2026 and agrees with Lerner's list on 99.2 percent of the blocks, as Cointelegraph reported in September 2026.

Values as of October 22, 2026, at a bitcoin price of $84,227 or €74,974 according to CoinMarketCap. Where the price stands today and which ranges analysts expect is covered in our bitcoin price prediction.

The estimate has three layers of very different strength. It is well established that a single machine produced these blocks. That this machine belonged to Satoshi is only circumstantial: the pattern starts with the first block, and Lerner himself speaks of compelling reasons, not proof. Whether Satoshi still holds the keys today cannot be tested at all.

Satoshi Nakamoto and BIP-361: freezing the old coins

Satoshi's coins sit in an early address format in which the public key is visible on the blockchain. A sufficiently powerful quantum computer could derive the private key from it. The draft BIP-361, added to the official repository in February 2026 with developer Jameson Lopp as lead author, would therefore lock such coins after several years of notice.

The plan has two stages. Around three years after activation, or 160,000 blocks to be precise, the network would stop accepting payments to vulnerable addresses. About two years later, the old signatures would only be valid through a recovery procedure that, according to the authors, does not work for Satoshi's address format. His coins would then stay frozen, unless a separate proposal known as "Hourglass" creates a slow spending path for such legacy outputs, which the authors explicitly support. The draft still carries the status "Draft", and a soft fork lacks broad support. We have set out the arguments on both sides in our piece on why 1.1 million of Satoshi's coins could be frozen.

Satoshi Nakamoto's coins and the market: what a movement would mean

If a coin from a Patoshi block moves, everyone sees it immediately, because every transaction is public. Nobody can see who triggered it: Satoshi, an heir, or an attacker who has cracked a key. And a movement is not yet a sale.

There are solid comparisons for the scale. The estimated holdings of around 1.1 million bitcoin equal roughly three times the 24-hour trading volume CoinMarketCap reported on October 22, 2026 ($30.6 billion). In July 2025, Galaxy Digital sold more than 80,000 bitcoin for a Satoshi-era investor, worth over $9 billion at the time and one of the largest bitcoin sales ever. Satoshi's estimated holdings are almost 14 times as large.

Our view: more than 16 years of inactivity allow three explanations, lost keys, a deliberate decision not to spend, or an inventor who does not want to be found, and none of them can be tested from the outside. For anyone holding bitcoin, the case carries a practical lesson: whoever holds the key owns the coins.

Satoshi Nakamoto: without a signature, every name is a guess

After 15 years of silence, the picture is clear. The white paper, the code, the emails and the first blocks are documented, Craig Wright has been ruled out by a court, and all the other candidates have denied it, in their lifetime or through their families. Bitcoin has worked without its inventor since January 3, 2009, and the open question is shifting: away from the person and towards the coins, and whether the network protects them from quantum computers or freezes them.
