Abstract
Our blockchain-powered electronic examination system marks a profound shift in educational assessments. Leveraging blockchain’s immutable nature, we introduce a seamless, secure examination management process. It commences with student registration, where individuals establish unique blockchain identities, guaranteeing personal data integrity.
The core of our innovation resides in the examination process. All questions and answers reside securely on the blockchain, impervious to manipulation or fraud. Students engage via a user-friendly interface, submitting answers directly to the blockchain. Smart contracts execute automatic grading, ensuring consistency and banishing human error.
Our distinctive feature lies in unwavering commitment to transparency and security. System-issued electronic certificates are verifiable and tamper-proof, bolstering academic achievements’ credibility. To fortify security, biometric authentication (e.g., facial recognition or fingerprint identification) validates the test-taker as the registered student.
A prominent differentiator is advanced cryptography use, including Zero-Knowledge Proofs (ZKPs), ensuring examination records’ confidentiality. ZKPs allow data integrity verification without sensitive information exposure, preserving privacy and averting answer leaks.
We champion fairness and inclusivity, echoing Sustainable Development Goal 4 (Quality Education). Our system dismantles resource-based barriers, affording quality education to all, neutralizing socio-economic impact on learning outcomes.
Our solution’s merits are multifaceted. It instills assessment process confidence, curbs cheating, and streamlines institutional administration. It empowers students and institutions alike to champion education’s highest standards, nurturing a future where quality education is an inalienable right for all.
