TL;DR
The paper addresses the challenge of securely verifying micro-credentials and enabling credit transfer across institutions in a context of rising higher-education costs and student attrition. It proposes a decentralized verification framework implemented on Hyperledger Fabric, combining on-chain hashes with off-chain storage and a wallet-based token system to manage micro-credential attestations and exemptions. The work details a complete architecture (framework, network, and chain-code) and a workflow that supports policy-driven course exemptions by partner institutions, aiming to improve credential trust, portability, and scalability. By enabling robust, auditable verification and flexible exemption mechanisms, the approach has practical potential to enhance recognition of prior learning and lifelong learning in a dynamic job market.
Abstract
Student retention is one of the rising problems seen in educational institutions. With the rising cost of education and issues in the education sector, such as curriculum relevance, student engagement, and rapidly changing technological advancements, ensuring the relevance of academic programs in a fast-evolving job market has created a significant concern for educational institutions. With the intent to adapt to such challenges, educational institutions are dealing with alternative solutions for education, in which micro-credentials are at the very center of this, which are short-term academic programs or standalone courses. However, one of the challenges of micro-credentials is a lack of credit transfer among institutions. With the lack of standardization of assessments among educational institutions, it is difficult to transfer micro-credentials to larger qualifications. Regarding such challenges, micro-credentials with blockchain technology can bring significant benefits. Blockchain technology offers a decentralized and immutable platform for securely storing and verifying credentials. This paper presents a prototype model for micro-credential verification. With the policies decided by the educational institution, the learner provides a micro-credential certificate to the system. Upon validation of the certificate by the verifying body, the educational institution will review the assessment criteria and provide exemptions based on the provided criteria. The prototype uses the Hyper-ledger Fabric platform and utilizes off-chain technology, which acts as a middle-man storage platform. With the combination of off-chain and on-chain technologies, congestion on the blockchain is reduced, and transaction speed is improved. In summary, this research proposes a prototype for secure micro-credential verification and a more efficient course exemption process.
