Bitcoin's greatest mystery solved by a style guide?

For 17 years, the identity of Satoshi Nakamoto, the inventor of Bitcoin, has been one of the internet's most enduring mysteries. Earlier this month, the New York Times published a remarkable piece of investigative journalism by John Carreyrou that may have finally cracked it. And the way he went about it is arguably even more interesting for language nerds than crypto bros.

Carreyrou and his team spent months combing through thousands of forum posts, emails, and technical papers. But they eventually realized the clues weren't in the content - they were in the writing itself.

The accidental style guide

The man Carreyrou suspects might be the bitcoin founder had a writing style that couldn't be fully concealed even under the Satoshi Nakamoto pseudonym. Here are some of the traces that point to him:

• Two spaces between sentences.

• British spellings throughout.

• Confused "it's" and "its."

• Placed "also" at the end of sentences.

• "Bugfix" as one word; "half way" and "down side" as two.

• Hyphenated "double-spending" unnecessarily; left "file sharing" and "noun-based" unhyphenated when they needed it.

• Alternated freely between "e-mail" and "email," "e-cash" and "electronic cash," "cheque" and "check," British and American spellings of "optimize."

Once Carreyrou and his team identified these distinctive writing habits, they began the task of filtering through thousands of old internet postings connected to the Cypherpunks movement, searching for someone whose style matched all of these quirks. Eventually, one author stood out: a linguistic fingerprint that included every single one of Satoshi's writing tics. It was Adam Back, a cryptography researcher who had been active in those communities since the early days of digital cash development.

When the writing speaks for itself

This got me thinking. If one person's unconscious habits are distinctive enough to surface across millions of words and seventeen years of careful concealment, what happens inside a brand written by many hands - copywriters, editors, reviewers, translators - each with their own hyphenation opinions and their own relationship with the em dash? While the world unpacks what this means for Bitcoin, the language geeks among us spotted a different kind of treasure: a very compelling case for the humble style guide.
