Adam Back rejects claims he is Satoshi Nakamoto

The true identity of Satoshi Nakamoto, the anonymous figure credited with creating Bitcoin, remains one of the most enduring mysteries in the world of technology. A recent investigation published by The New York Times has suggested that Adam Back could be the person behind the pseudonym. Back, however, has firmly rejected the claim.

For years, researchers, journalists, and enthusiasts have attempted to uncover the identity of Bitcoin’s creator, but without conclusive success. Despite the new investigation, it remains unclear whether journalist John Carreyrou — widely recognised for his reporting exposing Theranos — has achieved a definitive breakthrough.

Back’s background places him among the individuals often considered plausible candidates. He developed Hashcash, a proof-of-work system that later became a foundational component in Bitcoin mining. Today, he serves as co-founder and CEO of Blockstream, a firm focused on building infrastructure for blockchain-based payment technologies.

Interestingly, Back himself acknowledged that he fits the general profile of someone who could have created Bitcoin. He noted that it would not be unreasonable to assume that Satoshi might be a British cypherpunk in his fifties, similar to himself. Still, he pointed out that using a Japanese pseudonym in such a scenario would be somewhat unusual.

Despite these parallels, the investigation stops short of offering conclusive proof. Carreyrou’s approach involved analysing archived emails from cryptography mailing lists spanning from 1992 to 2008 — a period during which Satoshi was active in such forums. These archives were processed using artificial intelligence tools to identify stylistic similarities between Satoshi’s writings and those of other contributors.

The analysis highlighted patterns in writing style, such as the absence of hyphens in compound words and occasional confusion between “its” and “it’s.” Based on these linguistic markers, Back emerged as the closest match among the individuals studied.

However, Back dismissed the findings, stating on X that the similarities are likely due to coincidence and shared language patterns among people with similar technical backgrounds and interests.

While the mystery surrounding Satoshi Nakamoto remains unresolved, the investigation demonstrates a novel use of AI in historical and linguistic analysis. Even so, without definitive evidence, the question of who created Bitcoin remains open.
