The New York Times published an investigative piece proposing that British cryptographer Adam Back — creator of the proof-of-work system Hashcash — is the most likely candidate behind the Satoshi Nakamoto pseudonym used to create Bitcoin.
Back has denied the allegation, pointing to a post on X in which he repeated earlier rebuttals. He said he is not Satoshi and described his long-standing, focused interest in cryptography, online privacy and electronic cash work that produced Hashcash, which preceded Bitcoin.
The NYT investigation, led by John Carreyrou, builds a circumstantial case rather than presenting direct cryptographic proof. It emphasizes that Back was cited in Bitcoin’s white paper, was deeply involved in electronic-cash discussions for years, stepped back from public mailing lists around Bitcoin’s launch, and later reemerged as a prominent industry actor after Satoshi disappeared.
The report highlights stylometric and behavioral parallels. Analysts found overlaps in word choice and phrasing: Back reportedly used the hyphenated form “proof-of-work,” referenced the obscure Russian payment system WebMoney, and used expressions such as “partial pre-image” and a phrasing about “burning the money” that also appear in early Satoshi communications. The NYT frames these similarities as suggestive but not conclusive.
Carreyrou also points to Back’s career path as consistent with someone who might reenter the ecosystem under their real name: by 2013 Back became highly engaged in Bitcoin-related work, co-founding Blockstream, recruiting developers and helping raise significant funding to support infrastructure and development.
Many in crypto greeted the report with skepticism. Security veteran Jameson Lopp said stylometric analysis alone cannot reliably unmask Nakamoto, reflecting a broader view that linguistic and circumstantial evidence are insufficient to settle the question. Carreyrou acknowledged the limits of the investigation and said only cryptographic proof — for example control of Satoshi’s known private keys or a message signed by those keys — would constitute definitive evidence.
The NYT’s article renews long-running speculation by placing a prominent early cryptographer at the center of the inquiry, but it stops short of producing the cryptographic confirmation that would settle Satoshi’s identity. Cointelegraph notes this report follows editorial standards; readers should evaluate the evidence and seek independent verification where possible.
