Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism and encryption algorithm. The Blockchain, an important concept for Bitcoin, is essentially a decentralized database, and as the underlying technology for Bitcoin, is a series of data blocks that are linked together using cryptography, each block contains a batch of information about a bitcoin network transaction, used to verify the validity of its information (anti-counterfeiting) and generate the next block. The original English version of the BITCOIN White Paper does not actually contain the term blockchain, but uses the term chain of blocks. In the original Chinese translation of the Bitcoin White Paper, chain of blocks was translated into blockchains. This is the earliest appearance time of the Chinese word “Blockchain”. The State Internet Information Office of the People’s Republic of China promulgated the Provisions on the Administration of Information Services on blockchains on January 10,2019, which will take effect from February 15,2019
