Key Points:
- An estimated 1.1 million BTC is widely attributed to Satoshi Nakamoto based on a distinctive early mining pattern known as the “Patoshi” pattern, but the blockchain does not identify the person behind those coins.
- Bitquery’s analysis found strong evidence that the Patoshi blocks were mined by a single operation, while the connection between that operation and Satoshi remains circumstantial.
- The estimated size of the Patoshi holdings ranges from just under 900,000 BTC under a strict interpretation of the fingerprint to roughly 1.17 million BTC under the broadest interpretation.
The Bitcoin Blockchain Can Trace Coins, Not Their Owners
Satoshi Nakamoto’s estimated Bitcoin fortune has long been one of the most closely watched mysteries in the cryptocurrency market.
Approximately 1.1 million BTC is commonly attributed to Bitcoin’s pseudonymous creator, but the estimate does not come from a wallet labeled as belonging to Satoshi. Instead, it is based on forensic analysis of Bitcoin’s earliest mining activity.
That distinction became particularly important after 600 BTC from 12 block rewards mined in March 2010 moved in September after remaining dormant for roughly 16 years.
The transactions triggered speculation that Satoshi-era coins had become active. However, blockchain analysis did not establish a connection between those coins and the mining operation generally associated with Satoshi.
Bitquery found that 10 of the 12 blocks did not match the distinctive Patoshi mining pattern, while the remaining two showed only weak matches that could have occurred by chance.
The coins were controlled by whoever possessed their private keys, but the blockchain cannot establish whether that person was the same individual who mined the Bitcoin in 2010.
The Patoshi Pattern Created the Satoshi Fortune Estimate
The foundation for the 1.1 million BTC estimate dates to 2013, when researcher Sergio Demian Lerner identified a distinctive fingerprint across Bitcoin’s earliest blocks.
The pattern, subsequently known as Patoshi, suggested that one mining operation was using its hardware differently from other miners and could be tracked across thousands of blocks.
Lerner estimated that the operation accumulated approximately 1.1 million BTC.
More than a decade later, Lerner continues to support the estimate while emphasizing that the evidence is circumstantial rather than mathematical proof.
The connection to Satoshi is strengthened by several early Bitcoin transactions. Lerner identified transfers to early Bitcoin participants including Hal Finney, Dustin D. Trammell, Nicholas Bohm and Mike Hearn that originated from coinbase transactions displaying the Patoshi pattern.
Lerner argues that the combination of the mining fingerprint, the timing of the operation and the early transfers provides substantial circumstantial evidence connecting Patoshi to Satoshi.
It does not, however, constitute direct proof of identity.
Bitquery Reconstructs the Early Mining Operation
Bitquery later rebuilt the Patoshi analysis from Bitcoin’s raw blockchain data.
The firm examined 54,316 early Bitcoin blocks and tracked the resulting coins through Sept. 1, 2026.
Its highest-grade reconstruction matched the publicly available Patoshi block list on 99.2% of blocks. Bitquery also found no exceptions in a timestamp-ordering test covering 5,836 adjacent block pairs.
That provides strong evidence for the existence of a distinctive and consistently identifiable mining operation.
But the analysis also demonstrates why the 1.1 million BTC figure should be treated as an estimate rather than a precise balance.
When Bitquery applied the fingerprint strictly, it identified just under 900,000 BTC. Under its most generous interpretation, the pattern covered approximately 1.17 million BTC.
The commonly cited estimates of roughly 1 million to 1.13 million BTC fall within that range.
Three Separate Claims Are Often Combined
Bitquery researcher Gaurav Agrawal separates the Satoshi wealth question into three distinct claims.
The first is that the coins were mined by a single machine or mining operation. The available blockchain analysis provides strong evidence for that conclusion.
The second is that the machine belonged to Satoshi Nakamoto. That connection remains circumstantial.
The third is that Satoshi still controls the corresponding private keys. The absence of movement from many of the associated coins does not prove that the original miner continues to control them.
Private keys can be transferred, inherited, stolen or recovered years later.
As a result, blockchain data can establish that specific keys controlled specific Bitcoin at particular points in time, but it cannot independently identify the individual holding those keys.
A 2010 Transaction Provides Another Clue
Bitquery also identified a 2010 transaction that had not appeared in the published studies examined by the firm.
On May 17, 2010, 600 BTC from early mining rewards moved in two transactions approximately one hour apart.
The first transaction, at 22:04 UTC, spent 10 block rewards totaling 500 BTC. The second, at 23:07 UTC, spent another two rewards totaling 100 BTC.
The underlying coins had been mined at different points throughout 2009, including blocks from near the beginning and end of Bitcoin’s first year.
According to Agrawal, the transactions are notable because the blockchain itself provides evidence that the block rewards were controlled together, rather than the conclusion being based solely on statistical similarities in mining behavior.
The evidence still does not identify the person controlling the keys.
The September Bitcoin Movement Does Not Confirm Satoshi Activity
The 600 BTC that moved in September should therefore be separated from the broader Patoshi analysis.
Bitquery found that most of the 12 blocks involved in the movement did not match the Patoshi fingerprint, while the two weaker matches were not sufficient to establish a connection.
The spending transactions also used modern wallet software that could not have produced the original 2010 transactions, indicating that the old private keys were at some point imported into newer software.
That establishes control of the keys at the time of the recent spending, but not the identity of the person controlling them.
Outlook
The evidence surrounding Satoshi Nakamoto’s estimated 1.1 million BTC remains a combination of blockchain forensics and circumstantial reasoning. The Patoshi pattern provides strong evidence of a distinctive early mining operation and allows researchers to estimate the amount of Bitcoin associated with it, but it does not contain a cryptographic identity proving that the miner was Satoshi. Likewise, dormant coins moving after many years can demonstrate that someone controls the corresponding keys without establishing who that person is. For now, the size of the Patoshi fortune can be estimated, but its ultimate owner remains unconfirmed.
