摘　　要：学历学位是衡量学生知识水平和社会认可度的重要证明,而现有学历学位数据管理系统存在中心化、易篡改及难以追溯等问题,导致出现造假现象。区块链数据具有不可篡改、可存证、可追溯的特点,将区块链应用于学历学位管理系统,可对学历学位获得过程进行溯源。文章基于区块链和智能合约技术,设计了一套可信的学历学位认证系统,从效率和可信度平衡、访问控制安全等角度展开设计工作,并详细介绍系统的运转流程,为学历学位认证可信溯源的发展提供参考。Education and degree is an important certification to measure students'knowledge level and social recognition,while the current data management system of education and degree has problems.The problems are centralization management,easy to tamper with and difficult to trace,which lead to the phenomenon of fraud.Data on blockchain has the characteristics of non-tampering,credible storage and traceability.The application of blockchain in education and degree management system can trace the process of obtaining education and degree certification.In order to provide a reference for the development of credibility traceability of education and degree certification,the paper designs a trusted education and degree certification system based on the technology of blockchain and smart contract,considering the balance between efficiency and credibility,access control security measures etc.,and introduces the operation process of the system in detail.
