In order to enhance the effectiveness of enterprise financial risk management in the big data environment, this paper designs and implements a financial risk monitoring system based on big data analysis and blockchain technology. Descriptive statistical analysis, machine learning and deep learning models are used for financial risk identification and assessment, while blockchain technology is combined to strengthen the security and transparency of data. It is found that the deep learning model performs well in identifying complex financial risks, and the blockchain technology effectively improves the reliability and auditing efficiency of the risk management system. The results show that the comprehensive application of the above technologies can improve the early warning capability and management level of financial risks.
