A new investigation published by the New York Times has reignited questions about the identity of “Satoshi Nakamoto,” the pseudonym behind Bitcoin’s creator. The investigation suggests Adam Back, a British cryptographer, could be Satoshi. However, Back has denied the allegation. According to TechCrunch, the investigation relies on AI analysis of writing patterns from archived emails, but lacks definitive proof to confirm Back’s identity as Bitcoin’s creator.
The Claim and the Denial
The New York Times investigation, reported by tech journalist John Carreyrou, proposes that Adam Back could be Satoshi Nakamoto. Back has publicly denied this claim. The identity of Satoshi remains unresolved after decades of speculation. Carreyrou, known for his reporting on Theranos, has not presented evidence that conclusively establishes Back as Bitcoin’s creator, according to TechCrunch’s coverage.
Why Back Fits the Profile
Back is considered a plausible candidate based on his technical background. He created Hashcash, a proof-of-work system that Satoshi used to mine Bitcoin. Back is currently co-founder and CEO of Blockstream, a company building infrastructure for blockchain-based payment systems. Back himself acknowledged that Carreyrou’s suspicion is reasonable, noting that Satoshi could be a fifty-something-year-old British Cypherpunk—a description that aligns with his own profile. In a statement on X, Back wrote: “i’m not satoshi, but I was early in laser focus on the positive societal implications of cryptography, online privacy and electronic cash, hence my ~1992 onwards active interest in applied research on ecash, privacy tech on cypherpunks list which led to hashcash and other ideas.”
The Investigation’s Methodology
Carreyrou collected archives of emails from three cryptography listservs spanning 1992 to 2008, the period when Satoshi was active in these forums. He then used AI to analyze the archives and identify writing patterns common to Satoshi and other posters. The analysis identified specific stylistic traits: Satoshi did not use hyphens in compound nouns and sometimes confused “its” and “it’s.” Back emerged as the best match according to the AI analysis, though Back disputes the conclusion.
Limitations of the Evidence
Despite the AI-driven analysis, Carreyrou does not have undeniable evidence to confirm Back’s identity as Satoshi. The investigation illustrates how modern methods combining historical records with AI stylometry can identify patterns but may fall short of providing conclusive proof. The case highlights the challenges of attribution when the subject is a pseudonymous figure whose technical contributions are foundational to systems like proof-of-work.
