This project develops a blockchain-based system for secure issuance, storage, and verification of academic and professional certificates. It employs Ethereum smart contracts to create an immutable, decentralized ledger that prevents forgery and enables instant authentication. Users submit requests with details and documents, which administrators review and approve or reject. Approved certificates receive on-chain storage with unique transaction hashes for global verification without intermediaries. The platform includes role-based interfaces: users handle requests and tracking, while administrators manage approvals and analytics. Integration with file uploads and status notifications enhances usability. The system addresses vulnerabilities in traditional methods by leveraging blockchain's immutability, transparency, and decentralization. Testing demonstrates near-instant verification, zero tampering risk, and efficient workflows. This solution benefits educational institutions, employers, and individuals by reducing fraud, costs, and delays in credential validation. It establishes a trustworthy digital ecosystem for qualifications in the modern era.
