+# 🚀 QNet Explorer Deployment Guide
+
+## 📋 Overview
+
+The QNet Explorer is a Next.js-based blockchain explorer that provides a web interface for interacting with the QNet blockchain. After the project restructuring, all components are properly organized and ready for deployment.
+
+## 🏗️ Architecture
+
+```
+QNet Explorer
+├── Frontend (Next.js) - Port 3000
+│   ├── Web Interface
+│   ├── API Routes (/api/*)
+│   └── Real-time Updates
+└── Backend Integration
+    ├── QNet Node API (Port 8545)
+    ├── Blockchain Data
+    └── WebSocket Connections
+```
+
+## 🖥️ Local Development
+
+### Prerequisites
+
+- Node.js 18+
+- npm or yarn
+- Git
+
+### Quick Start
+
+```bash
+# Clone repository
+git clone https://github.com/AIQnetLab/QNet-Blockchain.git
+cd QNet-Blockchain/applications/qnet-explorer/frontend
+
+# Install dependencies
+npm install
+
+# Start development server
+npm run dev
+
+# Access at http://localhost:3000
+```
+
+### Development Scripts
+
+```bash
+# Development with hot reload
+npm run dev
+
+# Development with Turbopack (faster)
+npm run dev:turbo
+
+# Build for production
+npm run build
+
+# Start production server
+npm start
+
+# Lint and format code
+npm run lint
+npm run format
+```
+
+## 🌐 Production Deployment
+
+### Method 1: Simple Deployment Scripts
+
+#### Windows
+```bash
+# Run the deployment script
+deploy.bat
+```
+
+#### Linux/macOS
+```bash
+# Make script executable
+chmod +x deploy.sh
+
+# Run deployment
+./deploy.sh
+```
+
+### Method 2: Docker Deployment
+
+```bash
+# Build and run with Docker Compose
+docker-compose up -d
+
+# Check status
+docker-compose ps
+
+# View logs
+docker-compose logs -f
+```
+
+### Method 3: Manual Deployment
+
+```bash
+# Install dependencies
+npm install
+
+# Build for production
+npm run build
+
+# Start production server
+npm start
+```
+
+## 🔧 Configuration
+
+### Environment Variables
+
+Create `.env.local` file:
+
+```bash
+# API Configuration
+NEXT_PUBLIC_API_URL=http://localhost:8545
+NEXT_PUBLIC_WS_URL=ws://localhost:8545/ws
+
+# Network Configuration
+NEXT_PUBLIC_NETWORK=mainnet
+NEXT_PUBLIC_CHAIN_ID=1
+
+# Feature Flags
+NEXT_PUBLIC_ENABLE_FAUCET=true
+NEXT_PUBLIC_ENABLE_DAO=true
+NEXT_PUBLIC_ENABLE_STAKING=true
+
+# Analytics (Optional)
+NEXT_PUBLIC_GA_ID=your-google-analytics-id
+```
+
+### Production Environment
+
+```bash
+# Production API endpoints
+NEXT_PUBLIC_API_URL=https://api.qnet.io
+NEXT_PUBLIC_WS_URL=wss://api.qnet.io/ws
+NEXT_PUBLIC_NETWORK=mainnet
+
+# Security
+NEXT_PUBLIC_ENABLE_ANALYTICS=true
+NEXT_PUBLIC_SENTRY_DSN=your-sentry-dsn
+```
+
+## 📊 Monitoring
+
+### Health Checks
+```bash
+# Check application
+curl http://localhost:3000/api/health
+
+# Check specific endpoints
+curl http://localhost:3000/api/verify-build
+```
+
+### Log Management
+
+```bash
+# PM2 logs
+pm2 logs qnet-explorer
+
+# Docker logs
+docker logs qnet-explorer
+
+# Nginx logs
+sudo tail -f /var/log/nginx/access.log
+sudo tail -f /var/log/nginx/error.log
+```
+
+### Performance Monitoring
+
+```bash
+# PM2 monitoring
+pm2 monit
+
+# System resources
+htop
+df -h
+free -h
+```
+
+### Backup & Updates
+
+```bash
+# Backup current deployment
+tar -czf qnet-explorer-backup-$(date +%Y%m%d).tar.gz /home/qnet/QNet-Blockchain
+
+# Update deployment
+cd /home/qnet/QNet-Blockchain
+git pull origin master
+cd applications/qnet-explorer/frontend
+npm ci --only=production
+npm run build
+pm2 restart qnet-explorer
+```
+
+## 🔒 Security Considerations
+
+### SSL/TLS Configuration
+
+```bash
+# Install Certbot for Let's Encrypt
+sudo apt install certbot python3-certbot-nginx
+
+# Obtain SSL certificate
+sudo certbot --nginx -d your-domain.com
+
+# Auto-renewal
+sudo crontab -e
+# Add: 0 12 * * * /usr/bin/certbot renew --quiet
+```
+
+### Firewall Configuration
+
+```bash
+# Configure UFW
+sudo ufw allow ssh
+sudo ufw allow 80
+sudo ufw allow 443
+sudo ufw enable
+```
+
+### Security Headers
+
+Add to Nginx configuration:
+
+```nginx
+add_header X-Frame-Options "SAMEORIGIN" always;
+add_header X-XSS-Protection "1; mode=block" always;
+add_header X-Content-Type-Options "nosniff" always;
+add_header Referrer-Policy "no-referrer-when-downgrade" always;
+add_header Content-Security-Policy "default-src 'self' http: https: data: blob: 'unsafe-inline'" always;
+```
