Noir Membership Proof System

A zero-knowledge membership proof system built with:

• Tauri v2 - Cross-platform desktop application
• Angular - Frontend UI framework
• Noir - Zero-knowledge circuit language
• Barretenberg (bb) ZK proof prover
• Rust - Backend cryptography and Tauri integration
• SQLite - Member database

What This Does

1. Store members in a database with SHA256 commitments
2. Generate proofs using Noir circuits and Barretenberg to create zero-knowledge proofs
3. Verify proofs cryptographically that a user knows a member's secret without revealing it
4. Display results with responsive UI and real-time feedback

Key Features

• 🔐 Pre-hashed secrets (SHA256 → BN254 field reduction)
• 🌳 Merkle tree commitment verification
• 📝 Zero-knowledge circuit logic in Noir
• 🖥️ Cross-platform desktop app with Tauri
• 🎨 Responsive Angular UI with real-time feedback
• 📊 SQLite member database
• 📋 Comprehensive logging throughout
