The New York Times has published an investigation claiming that British cryptographer and Blockstream co-founder Adam Back is the person behind the Satoshi Nakamoto pseudonym. The report leans heavily on stylometric analysis of writing and Back's early involvement in cryptography discussions, but Back has categorically denied the claim. However, the larger concern within the Bitcoin development ecosystem is the security risks posed to anyone publicly associated with Satoshi, given the massive value of the dormant Bitcoin wallets linked to the mysterious creator.

Why it matters

Each new attempt to identify Satoshi Nakamoto shifts the story from an internet mystery to a real-world security liability. With the Satoshi-linked wallets now valued at an estimated $78 billion, falsely portraying ordinary people as the owners of this immense, inaccessible wealth exposes them to extortion, robbery, and cartel-level kidnapping risks.

The details

The New York Times investigation was spearheaded by John Carreyrou and Dylan Freedman, who spent over a year compiling a database of 134,308 posts from 620 candidates discussing digital money on cryptography mailing lists between 1992 and 2008. The team applied three separate writing analyses, filtering for grammatical quirks, British spellings, double-spacing between sentences, and the alternating usage of terms like 'e-mail' and 'email.' The analysis identified 325 distinct hyphenation errors in Satoshi's corpus, with Back allegedly sharing 67 of them. The Times also noted that Back outlined nearly every core Bitcoin feature on the Cypherpunks list between 1997 and 1999, a decade before the Bitcoin whitepaper.

  • In late 2008, Satoshi Nakamoto announced Bitcoin.
  • In June 2011, Adam Back returned to public commentary, six weeks after Satoshi vanished.

What they’re saying

“I am not Satoshi.”

— Adam Back

“Satoshi Nakamoto can't be caught with stylometric analysis. Shame on you for painting a huge target on Adam's back with such weak evidence.”

— Jameson Lopp, Co-founder and Chief Security Officer at Casa

What’s next

The Bitcoin development community is concerned about the security risks posed to anyone publicly associated with the Satoshi Nakamoto identity, given the massive value of the dormant Bitcoin wallets linked to the mysterious creator.

The takeaway

The latest attempt to unmask Satoshi Nakamoto highlights the inherent dangers of attaching a living person to the Bitcoin network, which was designed to be leaderless. Each new investigation shifts the story from an internet mystery to a real-world security liability, exposing ordinary people to extortion, robbery, and cartel-level kidnapping risks.
