Who created Bitcoin (BTC)?

Bitcoin is the first implementation of a concept called "cryptocurrency", which was first proposed by Wei Dai on the cypunpunks mailing list in 1998, proposing a new form of currency that uses cryptography to control its creation. Satoshi Nakamoto released the first Bitcoin specification and proof of concept on the encrypted mailing list in 2009. Satoshi exited the project in the second half of 2010, but did not disclose much information about himself. Since then, the community has grown exponentially, and many developers are committed to Bitcoin. 

Satoshi Nakamoto's anonymity often raises unreasonable concerns, many of which are related to misunderstanding the open source nature of Bitcoin. The Bitcoin protocol and software are publicly released, and any developer around the world can view the code or make their own modified version of the Bitcoin software. Like current developers, Satoshi Nakamoto's influence is limited to changes he has adopted by others, so he has no control over Bitcoin. Therefore, the identity of the inventor of Bitcoin may now be as important as the identity of the person who invented paper.
