Satoshi Nakamoto

No verified identity has ever been established. The record is text: a nine page paper, about two and a half years of forum posts and emails, and the code, ending with a message on April 23, 2011 saying the author had moved on to other things. What matters for a buyer is that the network has run since then without him.

How it works

Satoshi Nakamoto exists as a sequence of timestamped artifacts, which is why the pseudonym can be studied even though the person cannot.

The first artifact is an email to the Cryptography mailing list on October 31, 2008, announcing a paper on a peer-to-peer electronic cash system. The second is the genesis block, mined on January 3, 2009, carrying the front page headline of that day's Times of London about a second bailout for banks in its coinbase field. Version 0.1 of the software followed on January 9, 2009. Three days later, block 170 recorded the first transfer of coins between two people, 10 BTC sent to the cryptographer Hal Finney.

Then the withdrawal, in stages. The last post on the bitcointalk forum came in December 2010. Control of the source repository and of the network alert key passed to Gavin Andresen during 2011. The final message, sent privately to the developer Mike Hearn on April 23, 2011, said the author had moved on to other things and that the project was in good hands.

What does not exist is as informative as what does. No photograph, no recorded voice, no talk, no interview, and, most tellingly, no cryptographic signature from any of the early mining keys. Producing one would settle the question in seconds, which is why nobody claiming the name has ever managed it.

Why this matters when you buy bitcoin

Bitcoin having no locatable founder is a property of the asset, not a piece of trivia, and it shows up in three places that affect what you own.

There is no company behind it. No entity can be sued into changing the 21 million supply cap, no treasury holds a pre-mined allocation to sell into your bid, and no roadmap depends on a founder staying interested. Compare that with almost any other digital asset you will be offered alongside bitcoin, where a named team, a foundation, and a token allocation all exist and all have interests that differ from yours.

It shapes regulation, too. Regulators repeatedly separate bitcoin from tokens sold by promoters precisely because there is no issuer making promises, and that distinction is part of why bitcoin cleared the approval process for US spot exchange-traded products in January 2024 while most other assets did not.

It also creates a durable scam surface. Anyone claiming to be Satoshi, to represent his estate, or to run a giveaway on his behalf is running a confidence trick. The English High Court dealt with the highest profile version in COPA v Wright: after trial, the judge concluded on March 14, 2024 that Craig Wright is not Satoshi Nakamoto, with the full written judgment handed down on May 20, 2024. Treat any founder story attached to a coin offer as a reason to walk, and read our scam guide before you send anything to anyone.

The Patoshi coins

The largest untouched bitcoin holding in existence is attributed to Satoshi Nakamoto, and it can be measured without knowing who he was.

The researcher Sergio Demian Lerner noticed that a single miner in 2009 left a fingerprint in the fields miners are free to vary, restarting a counter in a regular pattern across a large fraction of the earliest blocks. That pattern, now called Patoshi, accounts for roughly 1.1 million BTC, a little over 5 percent of the eventual 21 million supply, sitting in tens of thousands of separate 50 BTC coinbase outputs.

Almost none of it has ever moved. The 10 BTC to Hal Finney in January 2009 is the well-known exception. The market's sensitivity to the question is easy to demonstrate: on May 20, 2020, 50 coins mined in February 2009 were spent, the price fell several percent within minutes, and analysts then established that the block in question sat outside the Patoshi pattern and so was probably not Satoshi's at all.

Treat those coins as a known unknown. They are a real overhang that has stayed still for more than fifteen years, and any plan that depends on them never moving is a plan with an assumption in it.

Satoshi Nakamoto vs a satoshi

Satoshi Nakamoto is a person; a satoshi is a unit. The capitalized name refers to the author of the whitepaper. The lowercase word refers to the smallest amount bitcoin can be divided into, one hundred millionth of a coin, a name proposed on the bitcointalk forum in late 2010 and adopted by convention rather than by any decision of the person it honors. When a wallet quotes a fee of 3,000 sats or an app advertises stacking sats, it is talking about the unit. Nothing in the protocol mentions either.
