Research on Accounting Information Credit Risk Measurement System Based on Blockchain

The accounting information credit risk measurement system has the problem of difficult information sharing, resulting in low ROC index. An accounting information credit risk measurement system is designed based on blockchain. The hardware part adds the support of a variety of high-speed interfaces in the module integration, selects the SoC chip as the main control chip of the processor module, and designs the clock circuit to realize the functions of timer and clock output. In the software part, the risk measurement system database is established, and the logarithmic processing method is used to describe the rate of return, so as to provide a data basis for risk measurement. A node uploads data to the network platform, establishes an accounting information credit risk measurement model based on the blockchain, and contracts with information circulate in the block to realize credit risk measurement. The system test results show that the ROC of the accounting information credit risk measurement system based on blockchain is higher than that based on SVM and random forest, and has good default prediction effect.
