Abstract: The credit collection is a necessary mechanism in many fields,including finance, financing, trade, transportation, etc. The current credit collection field has entered the fast lane. It is only by making good, active and practical use of credit collection and applying it to various fields of society that the construction of social credit system can be steadily promoted. Nowadays,traffic violations are frequent, the security of data storage in the traffic field is not easily guaranteed, and the traditional traffic field lacks a unified traffic credit metric, and the establishment of credit collection in the traffic field is a feasible solution to the above problems. In this paper, the new generation of blockchain credit model proposed by the credit group within the major project of the Ministry of Science and Technology is extended and applied to the field of traffic credit to build a smart traffic credit system. Based on the major project of the Ministry of Science and Technology, the paper focuses on the rapid implementation and empowerment of the real economy. For the first time, the technology will be applied to areas other than the financial field, and the scope of credit collection will be continuously developed.The technical depth will be strengthened, and on the basis of the previous technology, it will be combined with the new blockchain technology that meets the national conditions of China, such as ChainNet, Oracle Machine and STRISA(SilkRoad Travel Rule Information Sharing Architecture); the regulatory granularity will be refined, and a new regulatory entry trafficcredit system will be formulated; the traditional thinking will be changed, and the organizational structure of data entities will be transformed.
