Special Issue Information

Dear Colleagues,

This Special Issue, entitled "Blockchain Technologies: Trends, Challenges, Potentials and Applications", provides an in-depth analysis of the complex and diversified field of blockchain technology. It aims to examine the changing patterns, challenges, possibilities, obstacles, and wide-ranging application of blockchain technology across several fields. It also aims to provide a thorough overview of the latest developments and new paradigms in the field of blockchain, drawing on insightful contributions from top researchers and practitioners. The subjects addressed encompass a range of topics such as decentralized finance (DeFi), the interoperability of blockchain technology, solutions for scalability, processes for consensus, smart contracts, techniques for strengthening privacy, and scenarios for real-world deployment, among others. This Special Issue seeks to enhance comprehension of blockchain’s disruptive potential and promote its incorporation into practical systems and industries by combining state-of-the-art research findings and practical insights. Essentially, it will serve as a valuable resource for scholars, business experts, politicians, and enthusiasts seeking to navigate the rapidly evolving field of blockchain technologies.

Since its conceptualization in 2008, blockchain technology has advanced rapidly and been applied in multiple domains. In higher education, blockchain can be applied to develop ICT systems that can revolutionize student accreditation through certificate verification and micro-accreditations, which represent skills and other learning outcomes, in the form of digital/smart badges. While there are multiple studies that highlight the significance of blockchain in higher education and propose digital systems, few of those studies include the evaluation of such proposed systems by real users. As such, the research question of how useful a higher education blockchain system would be for its relevant stakeholders remains largely unanswered. In the research publication at hand, a blockchain-powered higher education platform was applied in the School of Electrical and Computer Engineering of the National Technical University of Athens, where it was used and evaluated by students and professors at the school. The evaluation of the platform was positive, and participants found that the smart badge functionality was among the most useful. Finally, the execution and evaluation of the pilot led to several lessons learned and policy recommendations towards dealing with existing barriers and further promoting blockchain in higher education.
