Decentralized Academic Credential Verification System (DACV)

A blockchain-based system for issuing, storing, and verifying academic credentials using Ethereum smart contracts and IPFS.

Features

• Credential Issuance: Universities can issue tamper-proof digital credentials
• Blockchain Verification: Instant verification through smart contracts
• IPFS Storage: Decentralized storage for credential documents
• Role-Based Access: Separate interfaces for Universities, Students, and Employers
• QR Code Support: Easy verification via QR codes
• Revocation System: Ability to revoke compromised or invalid credentials

Tech Stack

• Smart Contracts: Solidity with Hardhat
• Frontend: React + Tailwind CSS
• Storage: IPFS via NFT.Storage/Pinata
• Blockchain: Ethereum Sepolia Testnet
• Development: TypeScript, Ethers.js
