At present,the number of SME sippliers in China is very large,with more than 7,000 million.The difficulty in financing channels and the high cost of financing are huge problems faced by these enterprises.In recent years,the emergence of the concept of suply chain finance has provided an important theoretical basis and solution for the problem of financing difficulties for enterprises.It uses financial institutions such as banks as a link to link core enterprises and upstream and downstream suppliers to provide more flexible financial products and services.This paper will design and implement a supply chain financial service system based on the financing model of supply chain finance,combined with software engineering methodology and Internet-related technologies,and use the method of "financial+technology" to solve the dilemma of financing difficulties for SMEs.I participated in the design and implementation of the system's small payment certification module,SMS verification module,bill opening module,bill financing module,fund account management module and page config service module.In terms of design,the module is functionally decomposed and designed and detailed.In terms of implementation,the front-end builds the Node service and combines the React framework to manage the page configuration,encapsulate the interactive controls,parse the data and complete the page rendering.The back-end is based on Java and MySQL technology,which realizes the core business function.The data layer uses the blockchain technology to be tampered and the data traceable on the chain,performs distributed accounting,and collectively maintains a distributed shared ledger,so that the data is stored and shared among all nodes,and implemented trusted flow on the chain.At present,the system has been launched and successfully invited the core enterprises,suppliers and capitalists to enter the three roles,which makes the transactions between the core enterprises and suppliers transparent thus enhancing the credit rating of the suppliers and enabling them to obtain more funds.Financing opportunities to solve the financing problems of small and medium-sized supplier companies in the supply chain,ensure the ecological vitality of the supply chain,and promote the healthy development of the financial economy.
