Embodiment Construction
[0048] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0049]A blockchain is a decentralized database consisting of a continuously growing list of records called blocks. Each block contains a timestamp and a link to the previous block: the blockchain is designed so that the data cannot be tampered with, and once recorded, the data in a block is irreversible. Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain rights and interests between different nodes in the blockchain system. Blockchain (Blockchain) is...
