Design and application of a personal credit information sharing platform based on consortium blockchain

Abstract The technical features of blockchain, including decentralization, data transparency, tamper-proofing, traceability, privacy protection and open-sourcing, make it a suitable technology for solving the information asymmetry problem in personal credit reporting transactions. Applying blockchain technology to credit reporting meets the needs of social credit system construction and may become an important technical direction in the future. This paper analyzed the problems faced by China’s personal credit reporting market, designed the framework of personal credit information sharing platform based on blockchain 3.0 architecture, studied the technical details of the platform and the technical advantages, and finally, applied the platform to the credit blacklist sharing transaction and explored the possible implementation approach. The in-depth integration of blockchain technology and personal credit reporting helps to realize the safe sharing of credit data and reduce the cost of credit data collection, thereby helping the technological and efficiency transformation of the personal credit reporting industry and promoting the overall development of the social credit system.
