🔐 ProofVault

ProofVault is a decentralized notarization system that lets users store and verify document proofs (hashes) on the Ethereum blockchain.

✨ Features

• 📁 Upload files to generate unique SHA3 hashes
• 🔒 Store those hashes immutably on Ethereum
• 🧾 Verify ownership and timestamp of any proof

🧱 Smart Contract

The smart contract stores document hashes with owner and timestamp data:

mapping(bytes32 => Proof) public proofs;

🚀 Quick Start

1. Install dependencies

npm install

2. Compile contract

npx hardhat compile

3. Run tests

npx hardhat test

4. Deploy contract

npx hardhat run scripts/deploy.js --network <your-network>

Update the deployed contract address in frontend/app.js.

5. Open the frontend

Just open frontend/index.html in your browser with MetaMask enabled.
