Blockchain for Credibility in Educational Development: Key Technology, Application Potential, and Performance Evaluation

Abstract

Blockchain proposes many innovative technologies to establish credible mechanisms in an open environment and therefore, it becomes a promising solution to the problem of credibility in educational development. To better understand the role of the blockchain, we aim to provide an extensive survey focusing on its key technology, application potential, and performance evaluation. First, from the perspective of blockchain characteristics, we summarize its application architecture in educational credibility. Next, we extensively discuss application potential of the blockchain, such as data storage, data sharing, achievement certification, and activity evaluation. Moreover, we investigate the performance evaluation, including basic performance metrics and specialized metrics for credibility. Finally, we analyze the challenges and research trends of blockchain in educational credibility and provide useful insights for future research.

Applications of Blockchain-Based Technology for Healthcare Devices Post-market Surveillance

“…The speed of identifying and editing events can be hindered by the proliferation of PMS databases, which is problematic for situations where rapidity is crucial in PMS data transactions. To address this scalability issue, a blockchain solution should offer ample storage capacity while ensuring permanent retention of PMS data, all while maintaining fast performance and costeffectiveness [62]. For instance, this solution could involve the development of a platform that allows users to store PMS data on a blockchain indefinitely without compromising speed or affordability.…”
