The effectiveness and advantages of the partitioned blockchain method used is evaluated in a comparison with traditional models. The research results show that the overall recall rate of the adopted method for daily network attacks is very high. Compared with traditional models, the CPU and memory usage are lower, ensuring the scalability and efficiency of blockchain while achieving a more reliable information operation and maintenance.
