A new theory about Satoshi Nakamoto, the creator of Bitcoin, believes that it was created by an Estonian team or by one of the four people who formed the team. This is a company called Guardtime established in Estonia. Since 2008, it has been working on blockchain technology. It is widely believed that this technology was invented in 2008. According to an article in the media, there is some evidence to support the theory that Guardtime or the team associated with the company creates Bitcoin. According to Crunchbase, the company's founder and CEO, Mike Gault, began his career in quantum device research in Japan, holds a Ph.D. in electrical engineering from the University of Wales, and worked as a derivatives trader in Tokyo. This provides an indirect proof that he has become a Nakamoto: it explains the perfect English used by Bitcoin creators, the connection with Japan, and the time when Bitcoin was born. It is worth noting that although Nakamoto is said to be Japanese, his software does not have a Japanese indicator, and his perfect English is English spelling.
