This project introduces a blockchain-based e-vault system that ensures secure, transparent, and tamper-proof storage and verification of digital certificates. By utilizing the immutable and decentralized nature of blockchain technology, the system effectively eliminates risks associated with certificate fraud and unauthorized alterations. It features two types of users: Admin/Authorized Users, who can upload certificates with recipient details, and Normal Users, who are permitted to verify them. Upon successful upload, certificates are stored on the blockchain and recipients are notified via email with the certificate ID and related information. Users can access all their certificates through email-based login, with an optional Merge Account feature to combine multiple accounts for unified access. Additional functionalities include a Portfolio Page for resume generation, a dynamic pricing model to support institutional sustainability, a user guidance feature for easier navigation, and a live chatbot for real-time assistance. This system not only secures digital credentials but also empowers users and organizations with tools for professional development and efficient certificate management.
