Wu Qiuping, associate professor of the Information Network Center of the Party School of the Guangzhou Municipal Party Committee, said that Bitcoin is a landmark technology and financial innovation since the birth of the Internet. Of course, many people learn about the "blockchain" technology through "Bitcoin", but in reality, Bitcoin is not equal to the blockchain. Blockchain is essentially a trust mechanism. Through decentralized bookkeeping, machine trust is established, and the trust mechanism of modern society is reconstructed. This is also the most essential and core connotation of blockchain. The blockchain is Bitcoin's ledger. The ownership and transaction records generated by Bitcoin at any time are recorded in the blockchain ledger.
