The identity of Satoshi Nakamoto, the pseudonym of the creator of Bitcoin, remains a long-running mystery. But Satoshi could be Adam Back, a British cryptographer who conducted influential early research about digital assets. Back denies that he is Satoshi.

The public have been trying to track down the father of Bitcoin for decades, without much success. Based on Back, according to a fresh investigation published in the Latest York Times’s denial, it’s not clear if the Times’ tech journalist John Carreyrou, known for his reporting that took down Theranos, got much further than anyone else.

Back fits the profile of the kind of person you might suspect would create the first cryptocurrency. He created Hashcash, the proof-of-work system that Satoshi used to mine Bitcoin, and he is now the co-founder and CEO of Blockstream, a organization building infrastructure for blockchain-based payment systems. Back even agreed with Carreyrou that he’s a reasonable suspect, and it’s probable that Satoshi is — like him — a fifty-something-year-old British cypherpunk. (In that case, yes, the adopt of a Japanese moniker is odd.)

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.

But Carreyrou doesn’t have any undeniable evidence to seal the case shut.

To stake his claim, he collected archives of emails sent in three cryptography listservs between 1992 and 2008, during the time that the pseudonymous Satoshi was active in these forums. Carreyrou fed the archive into an AI to identify commonalities between how Satoshi and other active posters wrote. For example, Satoshi did not put hyphens in compound nouns, and sometimes mixed up “its” and “it’s.”

Back was the best match but wrote on X that the evidence is a “combination of coincidence and similar phrases from humans with similar experience and interests.”

The Satoshi case isn’t closed, but we have to admit, Carreyrou’s employ of AI was pretty clever.
