Abstract
The current micro-teaching process is readily online, and it is functional anywhere and anytime ubiquitously. All or most teaching and learning activities are accessible in centralized storage. However, centralized storage has inherent problems, such as a single point of failure with many possible data breaches, much duplication of data stored repeatedly in one location, and the lack of trust in third parties for data stored in centralized storage. Further issues include the high cost and low performance of the online systems that hinder the quality of the education process. In this paper, we propose a new framework Education Exchange Storage Protocol (EESP). EESP aims to improve the efficiency of the decentralized storage ecosystem in micro-teaching, coupled with blockchain technology acting as a control layer. Blockchain empowers the decentralized system by bringing together the most incompatible unstructured entities and integrate them. The decentralized storage system is armed with a blockchain smart contract that acts as a control layer, featuring impregnable security, immutability, trace-ability, and transparency. The EESP framework aims to elevate teaching and learning through blockchain decentralized storage systems in a transformational way, including but not limited to things like micro-credential, massive open online courses, and gamification, all in a single immersive learning platform. Finally, we tested and evaluated this framework using the truffle simulator, and the results demonstrate that the EESP model significantly improves performance.

This study proposes the Education Exchange Storage Protocol (EESP) which can support the micro-teaching process in higher education and can gain more benefits than data storage and sharing in traditional centralized storage systems
Avoid Single Point of Failure: Unlike traditional centralized storage, our EESP decentralized storage system adopted for higher education can solve the problem of a single point of failure in our solution
Summary
The entire education sector landscape has shifted because of the Covid-19 pandemic outbreak. Up to the current technology in time, the most necessity of storage for micro-teaching remains in a centralized database (Chiu, 2021). These configurations are largely prone to a data breach on confidential and sensitive data. The attempt causes inconsistent data redundancy and consumes unnecessarily large data storage space, leading to the increased overhead cost of centralized cloud storage services. Higher education must ensure that their micro-teaching data is appropriately accessible in the cloud by making multiple timely backups. Data leak cases like FacebookCambridge Analytica have resulted in a substantial shift from centralized to decentralized data storage systems at the time (Fahey and Hino, 2020). Future challenges suggest the direction of future research that will naturally be conducted by the authors of this paper or other authors interested in this research domain
