Abstract
Blockchain is a data structure of data blocks arranged in chronological order. It is featured by decentralization, trustworthiness, data sharing, security, etc. It has been widely used in digital currency, smart contract, credit encryption and other fields. With the development of the Internet technology, online education, a novel education mode, has been greatly popularized. However, this education mode still faces many problems in course credibility, credit and certificate certification, stu-dent privacy, and course sharing. Through literature review and case analysis, this paper discusses the basic technical principles and application features of blockchain technology, and proposes a solution to the problems of online educa-tion based on blockchain technology. The blockchain technology can store learn-ing records in a trusted, distributed manner, provide credible digital certificates, realize learning resource sharing with smart contract, and protect intellectual property through data encryption. The research shows that the integration of blockchain technology is a promising trend in the development of online educa-tion.
Highlights
Owing to the rapid development of Internet technology, online education has entered a stage of rapid growth since the turn of the century
massive open online courses (MOOCs) are featured by quality teaching programs and independent management systems
Considering the said problems of online education, this paper explores the nature and features of blockchain technology, and applies this technology in online educaiJET ‒ Vol 13, No 10, 2018
Summary
Owing to the rapid development of Internet technology, online education has entered a stage of rapid growth since the turn of the century. The learning process and results of MOOCs are short of public recognition and official certification; the students’ privacy is at risk, for the courses and data security solely depend on the centralized online education platform; the students’ intellectual property cannot be maintained effectively due to the openness of the Internet and the tamperability of data; there is no mature cross-platform course sharing mechanism to fully share the teaching resources. Blockchain technology is a desirable tool to solve the problems of online education, namely, poor certification, lack of recognition and data insecurity This technology is mainly applied in such field as finance, the Internet, and Internet of Things (IoT). Sony Global Education [6], a blockchain technology infrastructure platform under Sony Corporation of Japan, can openly and securely share learning courses and record data, without disclosing this information to the education management authority, realizing the fairness and digitization of education. The research findings pave the way to decentralized development of online education
