Design of treasury centralized payment counter cash withdrawal system based on blockchain Technology

In recent years, in order to realize the "safety, efficiency and convenience" of financial funds, the treasury centralized payment system is considered to be the key link to establish a modern financial system. The treasury centralized payment system developed under the treasury centralized payment system can minimize manual operation and improve work efficiency and management level. However, in actual operation, commercial banks are frequently troubled by various financial fund use security problems caused by teller operational risks. Almost all businesses handled by tellers hide potential operational risks, especially when making payment transactions at the bank counter, if the business cannot be handled correctly, it will reveal the privacy of customers and improve the risk of fund use. Then affect the normal development of commercial banks. In this context, this paper will take the Treasury Centralized Payment counter cash withdrawal and payment business as the research object, and design a treasury centralized payment counter cash withdrawal system based on blockchain technology. Taking advantage of the inherent decentralization, distributed authentication, transparent transmission and other characteristics of blockchain technology, the system not only realizes that transactions and transaction records cannot be tampered with, improves the security of payment, but also fully protects the privacy of customers. and solves the problems of fund use security and risks caused by improper teller operation under the traditional counter cash withdrawal system.
