A report has suggested British cryptographer Adam Back could be Satoshi Nakamoto, citing his work on Hashcash, writing style similarities and early cypherpunk activity. Back denied the claim, calling it speculation based on coincidences. The findings have reignited debate over Bitcoin’s mysterious origins without offering conclusive proof.

British cryptographer Adam Back is the most probable identity behind the pseudonym Satoshi Nakamoto, the elusive creator of Bitcoin, an investigative report reveals. The report draws on circumstantial evidence including Back’s pioneering work on Hashcash, a proof-of-work system that directly influenced Bitcoin’s design - his early involvement in the Cypherpunk movement, linguistic similarities in writing style, and patterns in online activity that align with Satoshi’s emergence and disappearance.

Adam Back Denies Being Satoshi

Back swiftly rejected the claims on X, stating, "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."

He added that he does not know Satoshi’s true identity and believes Bitcoin benefits from the mystery. Back described the NYT findings as a case of “confirmation bias” built on coincidences rather than conclusive proof.
