Design And Implementation Of Mobile App For Distributed E-commerce System

With the popularity of mobile devices such as smart phones and the rapid development of the E-commerce field,the mobile E-commerce model has brought new opportunities for E-commerce enterprises.In centralized e-commerce,the user's personal information transaction information is stored in a centralized manner on a third-party platform,and the lack of user privacy protection is becoming more and more obvious;and the third-party platform will charge high agency fees.In this article,the distributed E-commerce,also called as P2P E-commerce model,in which there are no intermediate services and fees,sellers and buyers directly deal with product information and transaction activities by "face-to-face",deviating from the original centralized management.These have led to a new direction for the development of E-commerce.The distributed E-commerce involved in this article is a decentralized e-commerce platform based on the foreign open source OpenBazaar distributed E-commrce framework.As an emerging e-commerce platform,at present,it only supports PC terminal,and the function only includes simple purchase,without registration and audit,recommendation service even other functions,which is obviously not acceptable to the public people in the era of mobile,this article aims at the distributed E-commerce system developed by the project team in the early stage.By analysis and summary,a design scheme of distributed E-commerce mobile terminal system is proposed.And design a distributed recommendation service model based on distributed e-commerce scenarios,taking into privacy protection and data openness.The article firstly introduces the research status of distributed e-commrce mobile terminal systems at home and abroad,investigates and analyzes the architecture of existing distributed E-commerce systems,and then combines the current mainstream mobile terminal development technologies and development models to design distributed E-commerce mobile app systems.The overall architecture of the commercial mobile terminal is separated from the existing distributed E-commerce system server,which is deployed on the cloud server as a personal server and is responsible for interacting with the blockchain network and the IPFS network.The mobile client corresponds to the personal server by one-to-one,Responsible for interacting with users and responding to business needs.At the same time,in combination with the basic requirements of the e-commerce system,a recommendation system server is added to the cloud,Based on the DSSM twin tower model,a distributed recommendation service model is designed and implemented to complete the recommendation service of the system.Finally,detailed function tests and performance tests are performed on the entire system,interface stability and stress tests are performed on the server-side system,and compatibility,adaptability,and fluency tests are performed on the mobile client to confirm that the system functions are normal.and do some performance tests on the recommended service plan to verify the accuracy of the recommended service and the test results meet expectations.At present,blockchain technology is in the initial stage of development in China and has received strong support from the country.Under the trend of the integration of blockchain and the real economy,the decentralized e-commerce mobile application designed in this paper has great market value and Application prospects.
