Is Adam Back Satoshi? Cryptographer Denies New NYT Report
British cryptographer Adam Back strongly denied claims on April 8, 2026, that he is Bitcoin’s mysterious creator, Satoshi Nakamoto, following a new investigation published by the New York Times that linked him to the pseudonymous developer using AI writing analysis.
The Hunt for Bitcoin’s Creator Heats Up
For nearly two decades, the true identity of Satoshi Nakamoto has remained the ultimate cryptocurrency mystery. The latest attempt to unmask the creator comes from renowned tech journalist John Carreyrou—famous for exposing the Theranos scandal—in his latest piece for the Times. However, despite the detailed investigation, Back has firmly rejected the theory, leaving it unclear if Carreyrou managed to get any closer to the truth than previous investigators.
Why Adam Back Fits the Satoshi Nakamoto Profile
On paper, Back is a highly compelling suspect. He is the creator of Hashcash, the pioneering proof-of-work system that Satoshi directly integrated to mine Bitcoin. Currently, Back serves as the co-founder and CEO of Blockstream, a leading firm developing core blockchain infrastructure.
Even Back admits he is a logical candidate, noting that Satoshi is likely a fifty-something British cypherpunk just like him—which would also explain the oddity of using a Japanese moniker. However, he maintains that he is not the man behind the cryptocurrency.
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.

How AI Was Used to Match the Cryptographers
Despite the compelling narrative, Carreyrou lacks definitive, smoking-gun evidence. To build his case, the journalist analyzed email archives from three cryptography mailing lists active between 1992 and 2008, a period during which Satoshi was highly active.
By feeding these archives into an artificial intelligence tool, Carreyrou sought stylistic similarities in writing. The AI flagged distinct habits, such as Satoshi’s tendency to avoid hyphens in compound nouns and occasional grammatical slips, like confusing “its” and “it’s.”
While the AI pointed to Back as the closest match, the cryptographer dismissed the findings. He wrote on X that the linguistic overlaps are merely a “combination of coincidence and similar phrases” shared by individuals with identical backgrounds and interests.
Although the mystery of Satoshi Nakamoto’s identity remains unsolved, Carreyrou’s innovative application of AI to historical archives marks a fascinating new chapter in the ongoing search.
