Who created Bitcoin?
Bitcoin is the first implementation of a concept known as "cryptocurrency," which was first described in 1998 by Wei Dai on the "cypherpunks" mailing list, where he proposed the idea of a new type of money that would use cryptography to control its creation and transactions, rather than being controlled by a centralized authority.
The first specification of the Bitcoin protocol and the proof of concept was published by Satoshi Nakamoto in 2009 on a mailing list. Satoshi abandoned the project in late 2010 without revealing much about himself. Since then, the community has grown exponentially and has numerous developers working on the Bitcoin protocol.
Who controls the Bitcoin network?
Just as no one controls the technology behind email, Bitcoin also has no owners. Bitcoin is controlled by all Bitcoin users around the world (they are called ‘miners’).
Bitcoin can only function correctly if there is consensus among all users. Therefore, all users and programmers have a strong incentive to protect that consensus.
