Comparative Research on Blockchain Consensus Algorithms Applied in the Internet of Things

The current Internet of Things system has security and privacy issues, insufficient resources and network transmission delays. The advantages of introducing blockchain technology are analyzed, and the blockchain architecture of the Internet of Things and the traditional Internet of Things are compared. This article mainly introduces the DPoS algorithm and the workload proof mechanism method. This paper uses the blockchain consensus algorithm of the Internet of Things to detect the Internet of Things, and establishes a potential DPoS algorithm model. The model is solved using the DPoS algorithm, and the blockchain consensus algorithm is evaluated, and the model is revised using historical data to improve the accuracy of the blockchain consensus algorithm evaluation. The experimental results of this paper show that the blockchain consensus algorithm improves the efficiency of the application of the Internet of Things by 53%, and reduces the false alarm rate and the false alarm rate. Finally, by comparing the blockchain consensus algorithm, the influence of the blockchain consensus algorithm on improving the application of the blockchain consensus algorithm in the Internet of Things is analyzed.
