Abstract

The consensus mechanism is a critical component of blockchain technology. To address the issue of delayed or ineffective handling of malicious nodes in the DPoS consensus mechanism, this paper proposed an improvement plan for the DPoS consensus mechanism based on SVM(SVM-DPoS). This approach firstly established a node discrimination model based on SVM, which analyzed the behavior motivations of nodes through a well-trained model, allowing for the timely elimination of malicious nodes based on discrimination results. Furthermore, it optimized the traditional block production process based on a fixed negotiated block order, enhancing the block production efficiency and consequently improving the overall operational efficiency of the blockchain network. Experimental results on public datasets indicate that compared to existing methods, the improved consensus mechanism can quickly eliminate malicious nodes. Not only does it maintain system stability, but it also strengthens the defense against malicious activities, thus ensuring the normal operation of the blockchain network while enhancing the overall security of the consensus.
