There are multiple challenges posed by the traditional online examination system in terms of security, scalability, and transparency. This manuscript considers providing a new and secure management system by using Distributed Ledger Technology (DLT). The proposed system employs smart contracts to demonstrate its capabilities to manage examination data with a high degree of security and efficiency. The creation, deployment and execution the smart contracts are tested. This decentralized solution not only enhances the integrity and transparency of the examination process but also enhances access for any institution, which makes this solution rather robust and reliable.
