Unreleased emails between Adam Back and the elusive Bitcoin founder, Satoshi Nakamoto, were revealed during the trial between the Crypto Open Patent Alliance (COPA) and Craig Wright on Thursday. Wright, who has stirred up controversy by asserting he is Nakamoto, is currently dealing with legal issues related to his efforts to copyright the BTC whitepaper and associated materials. The trial, occurring in the UK, has garnered significant attention in the crypto community because of its possible impact on the future of Bitcoin and the wider digital currency environment. Adam Back, an important person in the world of cryptocurrency who is considered to have influenced Nakamoto, presented emails as evidence during his testimony against Wright on February 22. These emails, from August 2008, show a conversation between Back and Nakamoto discussing the technical details of what would later become Bitcoin, the first and most important digital currency. This occurred before Bitcoin was officially launched. Nakamoto’s initial email is looking to verify the reference to Back’s Hashcash paper, which served as an early example of the proof-of-work system used in Bitcoin. Nakamoto’s statement suggests the initial development of Bitcoin, mentioning the intention to cite the Hashcash paper and utilizing hash-based proof-of-work to create a functioning electronic currency. In later emails, the two have a technical discussion, during which Back recommends that Nakamoto explore the B-money proposal by Wei Dai, a concept Nakamoto had not heard of before. This recognition is important because Wright has stated that he drew inspiration from B-money when creating Bitcoin. However, the emails indicate that Nakamoto only learned about B-money through Back, which raises doubts about Wright’s story. While testifying, Back highlighted the short and technical nature of his discussions with Nakamoto, explaining that they did not delve into intricate details and it was a straightforward conversation.
