Who created the Bitcoin crypto currency is still not known. According to the earliest popular version, the creator of bitcoin is a Japanese programmer named Satoshi Nakamoto. Whoever was hiding under the given name – a person or a group of like-minded people – is considered to have created the cryptographic protocol in 2008, and in 2009 launched the first Bitcoin client into the world wide web. Subsequently, Satoshi Nakamoto himself provided the development of the project to the Australian businessman Gavin Andresen, who continued to supervise and develop the project. Later, a programmer Craig Wright publicly admitted that he was the creator of bitcoin, demonstrating as proof the private key, which signed the ninth block containing the record on the very first transaction of this crypto currency. However, one should believe this fact or not as evidence remains an issue raised.
