Design And Implementation Of Electronic Coupon Management System Based On Block Chain Technology

Since 2008 Nakamoto,Satoshi first proposed to the center of the monetary system-Bitcoin(bitcoin)since the first block chain technology has brought a wave as the underlying support platform for Bitcoin encryption digital currency field,Then with the birth of contract system innovation,block chain technology begun to leave in the field of digital currency,to extend the application to financial transactions,securities clearing and settlement,identity authentication and other commercial contracts in related fields,With the continuous innovation of chain block technology,the low cost of credit creation,distributed structure and transparent characteristics gradually get the attention of the whole society,the scene also began to surpass the currency and contract category,one after another in finance,e-commerce,networking,medical,supply chain management,social welfare and other industries application.In this paper,based on the analysis of the current situation and development trend of the block chain technology,combined with the practical application of electronic coupons,this paper designs and develops a bank electronic coupon system.The system is to businesses,consumers and the electronic coupon information is stored in the block chain,through the intelligent contract to manage electronic coupons in circulation,and the right to use coupons,and chain blocks to the center,distributed books and data can not be tampered with and other characteristics,to achieve decentralization and streamlining business process.The overall design of the system uses B/S and C/S model architecture,Part of the project data stored in the block chain,part of the stored in the relational database,the operation of the MySQL database,using the Mybatis framework.On the etheric Fang node operation,know the current JavaScript web3.js package,so that relates to the Ethernet node square operation,we have to do with the nodejs,restful API to business logic layer The front controller uses Spring MVC framework,using the Spring framework to integrate Mybatis and Spring MVC framework.Web front-end involving Bootstrap,jQuery framework,front page display using JSP,javascript technology,using Ajax to request a partial update.Android app and background interaction through AsyncTask interaction.
