Enterprise’s Credit Information Sharing Model Based on Consortium Blockchain

Abstract

Due to the wide range of data sources and rich varieties of market-oriented credit reporting agencies, but the existence of competition among enterprises, the current credit reporting data among Chinese enterprises has not been able to form effective information sharing. The characteristics of block chain such as non-tampering, transparency, and data traceability provide audit and supervision basis for shared information. Based on the characteristic requirements of the enterprise credit investigation alliance chain network, a hierarchical network topology structure based on industry grouping is used to construct the credit investigation alliance chain. At the same time, in order to effectively reduce the communication complexity of the consensus process of the entire network, a hierarchical consensus mechanism based on the local and global integration of node credit is adopted.
