Decoding the Enigma of Satoshi Nakamoto and the Birth of Bitcoin
The first people Satoshi emailed privately were Mr. Back and Mr. Dai, both men have said. And Mr. Finney, who recently died, helped Satoshi improve the Bitcoin software in the fall of 2008, before it was publicly released, according to emails shared with me by Mr. Finney and his family.
.. Mr. Szabo’s writing about bit gold from that time contains many striking parallels with Satoshi’s description of Bitcoin, including similar phrasings and even common writing mannerisms. In 2014, researchers at Aston University, in England, compared the writing of several people who have been suspected to be Satoshi and found that none matched up nearly as well as Mr. Szabo’s. The similarity was “uncanny,” said Jack Grieve, the lecturer who led the effort.
