James A. Donald

From CryptoWiki

"James A. Donald was an anonymous Canadian cypherpunk who was the first person to comment on and critique Satoshi’s white paper and theories. Donald argued with Satoshi about scaling on more than one occasion and detailed that he believed Bitcoin needed a layer of account. “We will need a layer of account money on top of the bitcoins, supporting transactions of a hundred-thousandth the size of the smallest coin, and to support anonymity, Chaumian money on top of the account money,” Donald wrote.

On November 17, 2008, Nakamoto sent Donald the Bitcoin source code for his review. “I sent you the main files (available by request at the moment, full release soon),” Nakamoto stated at the time. There have been numerous theories that claim Donald and Nakamoto are essentially the same people and the creator was merely talking to himself during the emails. However, most of the James A. Donald theories that tie him to being Nakamoto have been debunked and thrown out the window. James A. Donald has not spoken to the Bitcoin community in years."
