According to John Carreyrou's investigation published by The New York Times on April 8, 2026, Blockstream CEO Adam Back matched 67 of Satoshi Nakamoto's 325 nonstandard hyphenation patterns, compared to 38 for the next closest candidate among 620 writers analyzed. Carreyrou stated he was 99.5% to 100% certain of his conclusion based on stylometric analysis.
Back denied the claim on X hours later, attributing writing overlaps to shared cypherpunk research interests rather than hidden authorship. Blockstream called the investigation "circumstantial," and Back produced 2008 emails showing Satoshi contacted him as a stranger before publishing Bitcoin's white paper. Bitcoin's price moved less than one percent following the report, reflecting market skepticism toward Satoshi identification claims lacking cryptographic proof.
