The Credit Tag Chain is a credit asset value network built on blockchain technology, which provides global coverage. The Credit Tag Chain combines the strengths of the blockchain technology and develops the smart contract of credit guarantee based on the CTC, the fiduciary relationship between the loan customers and the credit institutions is thus improved. By locking a certain amount of CTC via smart contract of credit guarantee, the loan customers obtain loans from the credit institutions, the data on the loan behaviour of the loan customers would be recorded in the block through smart contracts, helping the loan customers in credit information building, hence the credit information can be made available for checking and tracing. The credit information of the loan customers of the credit institutions may be inquired mutually through the blockchain, thus the credibility of the loan customers is increased, and the credit risks are significantly reduced, at the same time, the Credit Tag Chain would enable data inquiry to be more accurate, more convenient and safer through the privacy protection mechanism.The Credit Tag Chain is a decentralised service network. By recording the credit agreements between loan customers and credit institutions into smart contracts, the loan relationship between the loan customers and the credit institutions is more intuitive, transparent and it would be difficult to be tampered with.By building a distributed credit information system, all the users with loan needs can improve on the building of their personal credit information, the asymmetric information among the lending institutions would be solved, credit scale expansion is thus realised.Loan customers may obtain loans through freezing a certain amount in the CTC, the credit institutions may reduce credit risks which in turn, a more extensive range of loan customers would be served, and the loan customers would be provided with loan services which are of a lower interest, inclusive finance is thus actualised.
