Design and Implementation of Digital Currency Payment System based on Blockchain Technology

Against the backdrop of the rapid development of the digital economy, block chain has shown broad application prospects in the field of electronic currency due to its characteristics of transparency, security, and decentralization. On this basis, a prototype of an electronic currency payment system based on Ethernet can be constructed by combining existing theories and application foundations, and its operational efficiency and security have been empirically tested. In the design of the system, intelligent contracts can be used to automate transaction processing and verification, reducing the possibility of human error and deception. The block confirmation time increased from 2.0 seconds to 4.5 to 4.7 seconds, indicating that higher network latency prolonged the confirmation process of transactions in the blockchain, which had an impact on the real-time nature of transactions and user experience. Through testing, it has been proven that this new type of e-commerce platform has good operational efficiency and security performance, and has good application prospects.
