Satoshi’s 2010 Bitcointalk posts and AI stylometric verification

The 2010 Bitcointalk history

Satoshi Nakamoto published his final Bitcointalk message on December 12, 2010. He discussed version 0.3.19 and added DoS controls to the code. He removed "safe mode" alerts. Two days before this post, Bitcoin held a value of $0.20. Satoshi also expressed fear regarding the WikiLeaks scandal. He believed the heat from WikiLeaks would destroy the small, beta community.

He disappeared after this.

The 2010 forum history shows a creator focused on technical stability. Satoshi noted that writing descriptions for general audiences was "bloody hard." He told users that the technology was not yet ready for the exposure that political interest brought. He emphasized that the project needed to grow gradually so the software could be strengthened along the way.

AI and stylometric verification

AI models like Claude analyze the writing fingerprints of Satoshi. Researchers use Burrows’ Delta to measure language habits. This tool calculates how authors use more than 50 function words. It measures small word frequency to create a numerical fingerprint. This method remains reliable.

The tools work.

The AI compared the 2009 and 2010 forum posts. This test produced a Delta score between 0.31 and 0.39. These low numbers confirm the same author wrote both sets of messages. The analysis uses five distinct baselines. These include the Bitcoin whitepaper and various mailing list archives. The software evaluates 104,901 unique authors and 68,000 words of known writing. This method is more reliable than Naive Bayes classification, which is sensitive to topic overlap. For example, Phil Wilson’s technical writing matches Satoshi’s topics, but his function word patterns differ.

The candidates

The stylometric search identifies different candidates based on the baseline used. Ray Dillinger scored a Delta of 0.77 against the forum posts. He reviewed the source code before the January 2009 launch. Adam Back scored 0.91, which is in the same-author range. However, Back writes "can not" whereas Satoshi exclusively uses "cannot."

Back shares 67 of the 325 hyphenation errors.

Do you believe the data?

The investigation points to Adam Back as the strongest candidate because John Carreyrou and Dylan Freedman analyzed 34,000 mailing list posts to build their unique and extensive database of candidates. The report considers 620 candidates who discussed digital money. It observes that Back proposed decentralized electronic cash with built-in scarcity in 1999. These features match the Bitcoin whitepaper released a decade later. The report also mentions that Back invented Hashcash, a system that Satoshi incorporated into the code. Back denies the findings. He attributes the linguistic overlap to his high volume of posts. He is a long-standing Cypherpunk with deep roots in the community. He also suggested combining Hashcash with Wei Dai’s b-money concept, which is exactly what Satoshi did. The UIGEA gambling motive explains Satoshi’s secrecy. Bitcoin’s whitepaper appeared 12 days before the final regulations of the Unlawful Internet Gambling Enforcement Act. The Genesis Block was mined 16 days before the UIGEA compliance deadline. This timeline suggests Satoshi used extreme operational security to avoid regulatory heat.

Other candidates face dismissal. Nick Szabo scored a Delta of 1.33 against the forum posts. His writing style matches the whitepaper’s academic register but stays far from the conversational forum posts. Hal Finney, the first person to receive Bitcoin, also remains a subject of debate. Dorian Nakamoto, a physicist in California, faced scrutiny after a Newsweek article, but he denied all connections. Craig Wright claims to be Satoshi, but a UK High Court ruling in 2024 found he did not write the whitepaper.
