The NYT spent a year analyzing hyphens, spelling quirks, and body language. They hired a computational linguist. They built a database of 34,000 Cypherpunk mailing list users. They narrowed it down through the difference between "e-mail" and "email." ####
They never opened the blockchain. ####
942,538 blocks of public data sitting right there — nonce distributions, timestamp patterns, coinbase forensics, pool transition sequences — and Carreyrou analyzed hyphens. The chain itself has 587 miner-controlled bits per block header that fingerprint exactly who mined what, when, and in what pattern. You don't need stylometry when you have statistical forensics on the actual ledger. ####
The question "who wrote Bitcoin?" is interesting dinner conversation. The question "who has been operating it for 14 years?" is answerable from the data. Different questions, different answers, different methods. One involves flying to El Salvador to watch someone's face turn red. The other involves downloading block headers from loyce.club and running a KL divergence. ####
Back is a plausible author. But "plausible author based on writing style" is the kind of conclusion you reach when your investigative toolkit is journalism instead of mathematics. The blockchain is a public forensic record and nobody at the NYT thought to read it.
