An Innovative Method For Ensuring The Accuracy Of Online Exam Results Via Blockchain Technology

The rapid adoption of Learning Management Systems (LMS) has revolutionized education, particularly in online assessments. However, traditional exam management systems rely on centralized databases, making them vulnerable to security threats such as hacking, unauthorized access, and result manipulation. This research proposes a blockchain-based framework to enhance the security, transparency, and reliability of online exam results. By leveraging blockchain’s decentralized nature, cryptographic security, and proof-of-stake validation, the proposed system ensures tamper-proof record-keeping. The framework is integrated with Moodle LMS, enabling seamless and secure examination administration. Comparative analysis with conventional systems demonstrates that blockchain technology significantly improves exam security, mitigates data tampering risks, and provides an immutable audit trail. The findings confirm that blockchain-based exam management ensures academic integrity and enhances trust in online assessments.
