Abstract

Nowadays, internet technology plays a vital role in all the fields of our daily lives ranging from the world economy, professional careers, higher education, and almost all the spheres that are deeply impacted. In the current situation, due to COVID19, the dependence on the Internet for almost everything, including learning, getting daily needs, etc., is heavily dependent on the Internet. Online learning is made possible by the Internet, and today most students, educators, researchers are leveraging online learning platforms to enhance their knowledge at their own pace. Generally, the quality of the E-learning courses is evaluated with the help of the courses' review and rating mechanisms. In the present context, review systems are centralized, storing highly valuable information at one location and are liable to manipulation, hacking, and tampering. In this paper, the Blockchain-based Online Education Content Ranking system is proposed for an online review and ranking system that offers a decentralized trustworthy system, ensuring the integrity of the rating and the independence and integrity of content reviews by Subject Matter Experts (SME).

摘要

如今，互联网技术在我们日常生活的各个领域都发挥着至关重要的作用，涵盖世界经济、职业生涯、高等教育以及几乎所有受到深刻影响的领域。在当前形势下，由于新冠疫情，几乎所有事情，包括学习、获取日常所需等，都严重依赖互联网。互联网使在线学习成为可能，如今大多数学生、教育工作者、研究人员都在利用在线学习平台按照自己的节奏提升知识。一般来说，电子学习课程的质量借助课程的评价和评级机制进行评估。在当前背景下，评价系统是集中式的，将极有价值的信息存储在一个位置，容易受到操纵、黑客攻击和篡改。本文提出了基于区块链的在线教育内容排名系统，用于在线评价和排名系统，该系统提供一个去中心化的可信系统，确保评级的完整性以及主题专家（SME）进行内容评价的独立性和完整性。
