Abstract— This project uses blockchain technology to propose a safe, decentralized method of stopping question paper leaks. Exam question papers are stored and disseminated over a tamper-proof blockchain network, which guarantees their integrity, confidentiality, and traceability. Through the use of smart contracts and cryptographic techniques, this system ensures that only authorized personnel have access to the documents at predetermined times by providing an unchangeable audit trail. By reducing the possibility of human error, illegal access, and leaks, the platform improves security and confidence in the assessment procedures. The system has role-based access control in addition to its fundamental capabilities, which enables permissions to be given according to user roles and responsibilities within the examination authority. Transparency and traceability are ensured by recording all access requests and transaction pertaining to the question paper on the blockchain. Time-based smart contracts guard against early disclosure by guaranteeing that test questions are only available at predetermined times. The architecture can be implemented in a variety of educational institutions and testing organizations because it is made to facilitate scalability and interoperability. The system's resilience and reactivity to possible threats are enhanced via audit logs, encrypted question paper storage, and real-time alarm systems. In addition to improving the examination process's security and accountability, this blockchain-enabled system gives stakeholders more confidence by guaranteeing that academic assessments continue to be transparent, equitable, and impenetrable. The suggested approach lays the groundwork for safe, technologically advanced educational innovations.
