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