Jinwowo network analysis believes that: blockchain technology redefines the generation mode of credit in the network: in the system, participants do not need to know the background information of other people, nor do they need to rely on the guarantee or guarantee of a third party organization. Blockchain technology ensures that the system records, transmits and stores the activities of value transfer, and the final result must be credible.
