What is Bitcoin?
Bitcoin is a P2P digital currency. The concept of Bitcoin was first formally put forward by Satoshi Nakamoto on June 5438+065438+ 10/day, 2008, and was officially released on June 5438+1 October 3, 2009. As can be seen from Satoshi Nakamoto's design ideas, its open source software and construction are based on P2P network. In fact, the peer-to-peer transmission of Bitcoin also shows that it has a decentralized payment system. Unlike other issued currencies, Bitcoin is not issued by a specific monetary institution. It depends on a large amount of data output according to a specific algorithm. Bitcoin economy forms a decentralized database through scattered nodes in the whole P2 P network, thus confirming and recording all transaction behaviors.
