🔐 Privacy Features

  • Zero-Knowledge Processing: Data is encrypted before processing
  • Differential Privacy: Statistical noise for individual privacy
  • Homomorphic Encryption: Computation on encrypted data
  • Data Minimization: Only collect and process necessary data
  • Transparent Auditing: Complete audit logs for compliance

🚀 Getting Started

Prerequisites

  • Node.js 18+
  • Docker & Docker Compose
  • PostgreSQL 14+
  • Redis 6+
  • Rust 1.70+ (for Stellar contracts)
  • Soroban CLI (Stellar smart contract platform)

Installation

# Clone the repository
git clone https://github.com/your-org/stellar.git
cd stellar

# Run the setup script (Unix/Linux)
./scripts/setup.sh

# Or run the setup script (Windows PowerShell)
./scripts/setup.ps1

# Or manual setup
npm install
cp .env.example .env

# Install Stellar contract dependencies
cd contracts
cargo build --target wasm32-unknown-unknown --release
cd ..

Quick Start

# Start all services with Docker Compose
docker-compose up -d

# Or start development environment
npm run dev

# Deploy Stellar contracts to testnet
cd contracts
npm run deploy:testnet

# Access the application
http://localhost:3000
