A decentralized web application (dApp) to securely store and verify academic certificates using Blockchain (Ethereum + Ganache) and IPFS (via Pinata). It ensures tamper-proof, transparent, and trustless certificate validation.

- ✅ Upload a certificate file (PDF, PNG, etc.)
- 🔐 Generate a SHA-256 hash of the file for unique identity
- 📁 Upload the certificate to IPFS via Pinata
- ⛓ Store student name, certificate hash, and IPFS CID on a local Ethereum blockchain (Ganache)
- ✅ Verify certificate authenticity using the hash
- 🧒 MetaMask integration for wallet and transactions
| Technology | Purpose |
|---|---|
| React.js | Frontend Framework |
