A detailed writing analysis compared tens of thousands of words from early bitcoin communications with Dr. Adam Back’s correspondence, revealing matching patterns such as double spaces, British spellings and unique hyphen usage. The framework involved AI-led stylistic comparisons across three key Internet mailing lists, concluding Back’s syntax most closely aligns with Satoshi’s known writing.

Satoshi Nakamoto is believed to control approximately 1.1 million bitcoin, a cache roughly 44% larger than that of the largest corporate holder. This stash, if moved or sold, could exert substantial influence on bitcoin liquidity and price dynamics within the $2.4 trillion market.

In 1997, Back developed Hashcash, a proof-of-work algorithm designed to combat email spam that later became foundational to bitcoin’s consensus mechanism. His early research into electronic cash and privacy technologies on cypherpunk forums helped shape the cryptographic principles underpinning digital currencies.

Dr. Back has publicly denied the claim, emphasizing his longstanding focus on cryptography’s societal benefits and noting that his work on ecash and privacy predates bitcoin. He maintains that writing similarities are coincidental and has challenged the investigation’s conclusions on social media.
