BlockChain Certificate Issuer

The Blockchain Certificate Issuer is a decentralized application (DApp) built on the Ethereum blockchain that allows educational institutions to issue, store, and verify certificates in a secure and transparent way. Unlike traditional systems where certificates can be lost, forged, or manipulated, this system ensures that every certificate is immutable and verifiable directly on the blockchain.

The project leverages Solidity for smart contract development, Remix IDE for deployment, and MetaMask for secure wallet-based authentication and transaction signing. Each certificate is assigned a unique ID and permanently recorded on the Ethereum test network (Sepolia), making verification easy and trustworthy for students, institutions, and employers alike.
