摘要:
区块链(Blockchain)是一种把区块以链的方式组合在一起的数据结构,具有去中心化、按时序记录数据、集体维护、可编程和安全可信等特点。这项技术作为比特币的底层技术逐渐为业界所关注和应用,目前已经开始应用于信用背书、信息加密、智能合约等很多领域,并且在教育领域也有很大的应用潜力。在此,基于文献研究和案例分析方法,从区块链技术的原理和发展现状入手,介绍了这项技术诞生和发展的过程,其技术组成原理,在各个行业内的创新应用情况,以及社会学和哲学基础。进而专门讨论了区块链在教育领域的应用概况,这项技术在教育领域可以作为分布式学习记录存储;可为在线教育提供具有公信力和低成本的证书系统;可以作为智能合约,完成教育契约和存证;可作为版权证书工具标记教育资源和学术成果;还可以成为去中心化的全球知识库,以及知识货币。其后,分别介绍和讨论了当前教育区块链的主要应用模式,并以具体的案例加以说明。区块链可以提供去中心化的学习记录和学分银行服务,可以建立方便、可信的证书体系,可以降低求学、求职和人才雇佣的成本。最后,讨论了这项技术目前应用推广的优势和问题,并对研究做出总结。
Abstract:
Blockchain is a bundle of technologieschaining data blocks together, with a de-centralized, time-recorded, collectivelymaintained, programmable and security features. Nowadays, this technology has been applied to many fields, such as credit endorsement, information encryption, intelligent contract and so on.And it has shown a great potential in education and assessment. In this paper, based on the literature review and case study, it introduced the birth and development of blockchain; principle and mechanism;innovative application of this technology in various industries;and also its sociology and philosophical foundations. It can be used as intelligent contracts to prove and fulfill education transactions; as a distributed record storage in educationto build up a credible and low cost certificate system for online education; copyright certificate tool for educational resources and academic products; a de-centralized global knowledge base, and even intelligent currency. After that,the business models of educational blockchain are introduced and discussed respectively, with case studies for further illustration. Blockchain can be infrastructures of decentralized learning records repository as well as credit banking services system, and can establish a convenient and credible accreditation system that may reduce costs of university application, job hunting and hiring. At last, the advantages and problems of this technology in application are discussed and summarized to reach a conclusion.
