       Blockchain originated from Bitcoin. On November 1st, 2008, a person who called himself Satoshi Nakamoto published the article Bitcoin: A Peer-to-Peer Electronic Cash System, expounding the architecture concept of electronic cash system based on P2P network technology, encryption technology, timestamp technology and blockchain technology, which marked the birth of Bitcoin. Two months later, the theory was put into practice, and the first creation block with serial number 0 was born on January 3, 2009. A few days later, on January 9, 2009, the block with serial number 1 appeared, and it was connected with the creation block with serial number 0 to form a chain, marking the birth of the blockchain.
