Former theoretical physicists and French TV personalities Igor and Grichka Bogdanoff have said that they knew who created Bitcoin and were also part of the creation. The two brothers claimed that in the early 90s they worked with François Mizzi, the inventor of the touchscreen, whose lab included a Japanese scientist, Soïtchiro Shimoda. He was somewhat similar to Nakamoto. The Bogdanoff twins and Shimoda would often discuss ideas about a digital currency.
