Abstract :
Blockchain has made strides in multiple fields, including education. It offers transparent, secure, and decentralized storage for student records. A transparent assessment process, provided by blockchain is also vital in education. However, as the number of users and transactions grows, storage costs rise, and network performance declines. Therefore, a method is needed to increase scalability in a blockchain-based learning network, while keeping data and transactions secure. This paper presents a secure learning system using blockchain which improves the storage process, enables secure data sharing, and ensures assessment transparency through smart contracts. It utilizes a private Ethereum network and off-chain storage to enhance network performance and reduce costs. The proposed system aims to improve network scalability while maintaining security and data access control using encryption. The experimental results show that the proposed system has recorded a significant improvement in average transaction latency and has reduced file storage costs.
