🔖 Block Certify 📑

Blockchain-Based Certificate Generation & Validation

---

📌 Overview

Block Certify is a decentralized certificate issuance and verification system built on the Ethereum blockchain. It ensures that certificates are tamper-proof, verifiable, and securely stored as NFTs.

✅ Certificate Generation – Users can create certificates from templates and save them as PDFs.
✅ NFT Conversion – The certificate is converted into an NFT using SHA-256 hashing and stored on the Ethereum blockchain.
✅ Verification – Users can upload their certificates, and the system verifies their authenticity by matching hash IDs on the blockchain.
