An 18-month investigation by renowned journalist John Carreyrou recently rekindled the long-standing mystery of Bitcoin's creator, Satoshi Nakamoto, by controversially naming Blockstream CEO Adam Back as the elusive inventor. This claim, however, was swiftly met with strong rebuttals from prominent figures in the crypto community, who quickly highlighted significant historical inconsistencies that challenge the theory's validity.
The Stylometric Case for Adam Back
Carreyrou's investigation primarily leveraged "stylometry," a forensic technique that statistically analyzes linguistic style, phrasing, and writing patterns. By comparing Satoshi Nakamoto's known forum posts and the Bitcoin whitepaper with Adam Back's historical writings, Carreyrou concluded that their writing styles were sufficiently similar to identify them as the same individual. This method aims to uncover the author of anonymous texts by finding unique linguistic fingerprints.
Debunking the Theory with Historical Evidence
However, Michael Saylor, founder of Strategy, immediately countered Carreyrou's assertion with a critical piece of historical evidence: Satoshi Nakamoto and Adam Back actively communicated. Saylor pointed out that in the early days of Bitcoin's development, Satoshi famously emailed Back to discuss Hashcash, a proof-of-work system Back invented and which Satoshi cited in the Bitcoin whitepaper. For Carreyrou's theory to be true, Back would have had to meticulously forge email correspondence with his own alter ego, a scenario Saylor deemed highly improbable. Saylor emphasized that stylometry offers "interesting" insights but does not constitute proof, concluding that "Until someone signs with Satoshi’s keys, every theory is just narrative."
Broader Skepticism and Safety Concerns
The report faced widespread skepticism beyond Saylor's immediate rebuttal. Bitcoin evangelist Jameson Lopp harshly criticized the publication, expressing concern that it put "a huge target on Adam's back with such weak evidence." Bloomberg's Joe Weisenthal also voiced doubts, suggesting that stylometry is an inherently flawed tool for identifying cypherpunks, a group of developers known for sharing similar political and privacy ideologies, as well as views on internet architecture. This shared philosophical foundation could easily lead to similar writing patterns without indicating a single author.
