ZK Aadhaar

Zero Knowledge Aadhaar is a zero-knowledge proof solution that allows users to prove their Aadhaar identity while maintaining complete privacy and anonymity. This implementation uses React.js with Vite for a fast and efficient development experience.

Features

• Verify Identity Privately: Verify your Aadhaar identity without revealing actual Aadhaar data.
• Blockchain Proof Storage: Secure storage and verification of proofs on the blockchain.
• Client-Side ZK Proof Generation: Generate zero-knowledge proofs on the client side for maximum privacy.
• On-Chain Proof Verification: Verify previously generated proofs directly on the blockchain.
• No Aadhaar Data Storage: Only zero-knowledge proofs are stored, with no access to original Aadhaar data.

Technologies Used

• Frontend: React.js with TypeScript
• Build Tool: Vite
• Zero-Knowledge Proofs: Anon Aadhaar SDK
• Styling: CSS/SCSS
• Development: Node.js

Use Cases

• User Identity Verification: Verify your Aadhaar identity without revealing personal data.
• Business Authentication: Businesses can authenticate users while respecting privacy.
• Tamper-Proof Blockchain Storage: Verification proofs are securely stored on the blockchain.
• Selective Identity Verification: Users can choose which parts of their identity to verify.

How to Use

1. Connect Your Wallet:
   Start the application and connect your Web3 wallet (such as MetaMask) to interact with the system.

2. Upload Aadhaar PDF:
   Provide your Aadhaar PDF file through the secure interface for verification. Your data is never exposed.

3. Generate Proof:
   The application will generate a zero-knowledge proof of your Aadhaar data, which ensures that your personal information is kept private.

4. Proof on Blockchain:
   The zero-knowledge proof is then stored on the blockchain for verification purposes.

5. Verify Later:
   Anyone can verify your identity proof later without ever accessing or viewing your original Aadhaar data.
