The rise of mobile Internet has brought many business opportunities. There were many products that have changed our life. Electronic card is one of them. With in-depth contact with the electronic card which issued by different platforms, and we found that the electronic card can not be used in all platforms. So we need a third-party platform that we trust to manage all the electronic card issuing.In this paper, I have investigated the knowledge of Bitcoin. And design a system which try to save the electronic evidence of electronic card to Bitcoin platform. As the data of that platform can not be changed and decentralization maintenance of related software, the database record of electronic card can not be altered. Because everyone can freely access to the platform and all data of Bitcoin is open, users can verity record of issue and supervise the behavior of businesses. The main contributions of this dissertation are as follows:(1) Design a system which use underlying framework of the Bitcoin platform. This article firstly introduces the related technologies of Bitcoin. Then proposes a distributed system optimization scheme for issuing electronic card. Then designed module functions which base on the API of the software. To make the system allow businesses and users to participate in the maintenance of the system.(2) Implementation the system model, then to demonstrate the merchant issuing process and user’s functional testing. Prove that this method can really guarantee the effectiveness of the issue record and unchangeable of the data. |
