Digital Identity System

🎯 Project Overview

The Digital Identity System is a cutting-edge blockchain-based platform that leverages Zero-Knowledge Proofs (ZKP) to enable privacy-preserving identity verification. Built on the Solana blockchain, this system allows users to prove specific attributes about their identity (such as being over 18 years old) without revealing sensitive personal information like their exact birth date.

🌟 Key Features

• Privacy-Preserving Verification: Prove identity attributes without exposing personal data
• Zero-Knowledge Proofs: Uses advanced cryptographic techniques (Groth16 protocol) for secure verification
• Blockchain Integration: Stores proof references on Solana for tamper-proof verification
• Microservices Architecture: Scalable, distributed system with multiple specialized services
• Real-time Processing: Asynchronous message queuing for efficient proof generation and verification

🎯 Use Cases

• Age Verification: Prove you're over 18 without revealing your exact age
• Identity Authentication: Verify identity attributes for KYC compliance
• Privacy-Compliant Systems: Build applications requiring identity verification while maintaining user privacy
• Decentralized Identity: Create self-sovereign identity solutions

🔐 Security & Privacy

• Zero-Knowledge Architecture: No sensitive data is exposed during verification
• Blockchain Immutability: Proof references are stored on Solana for tamper-proof verification
• Cryptographic Security: Uses industry-standard Groth16 zero-knowledge proof system
• Decentralized Storage: No central authority controls or stores personal data`

✈️ Getting Started

Follow these steps to set up and run the project locally:

📋 Prerequisites

Before you begin, ensure you have the following installed on your system:

• Docker and Docker Compose (for containerized deployment)
• Rust (with Cargo)
• Solana CLI tools (the latest version)
• Go

docker --version
docker-compose --version
rustc --version
cargo --version
solana --version
go version

🚀 Start the system

Start the setup script. It will prepare the environment, keep solana-test-validator running, and get docker-compose up. To stop, use CTRL+C.

chmod +x setup.sh

./setup.sh
