A Distributed Credit Transfer Educational Framework based on Blockchain

摘要

Blockchain is an immutable and shared database of time–stamped transactions that supports decentralization and strong consistency support over many authoritative domains where trust is a major factor. The above advantage of Blockchain makes it potentially suitable for a diverse set of applications in many sectors like healthcare, education and finance. In this paper, we propose a globally trusted blockchain based educational framework among various stakeholders like universities, companies and other higher educational institutions that agree to collaborate as a part of the framework. This framework aids to verify academic certificates and course credits of a student registered in a university which can be digitally transferred among the stakeholders. This ensures a global view of a student’s performance by achieving consistency among the local copies of educational certificates and credits. The proposed framework will assign tokens on successful completion of courses as credits of registered students in various universities. The transferred credits will act as transactions mined as blocks and added to longest chain. It will work in a homogeneous environment where all stakeholders collaborate irrespective of the hurdles of legal and administrative policies.
