        abstract = {This paper briefly introduces the consensus algorithm in blockchain technology. In order to improve the efficiency and security of the consensus algorithm, on the basis of simplifying the consensus steps, the credit mechanism was introduced, and the improved algorithm was applied to the secure payment of digital economy currency transactions. Simulation experiments were conducted. The experiment tested the average response time and throughput of secure payment under different numbers of currency transaction items and different blockchain consensus algorithms. Moreover, the tampering status of transaction information under different numbers of tampered virtual nodes was also tested. The results showed that the average response time of secure payment under the improved practical byzantine fault tolerance consensus algorithm adopted in the currency transaction process was the most stable and shortest. It also had the largest throughput and could effectively resist attacks from third parties},
