Tech Stack

Backend

• Node.js + Express
• MongoDB (planned for caching)
• Socket.IO for real-time WebSocket updates
• SSH client for Mazacoin RPC connection
• Node-cache for query caching

Frontend

• React 18 with React Router
• TailwindCSS for styling
• Leaflet.js for interactive maps
• Chart.js for analytics (ready for expansion)
• Lucide React for icons
• QRCode.react for address QR codes

Infrastructure

• Docker + docker-compose
• Nginx (frontend reverse proxy)
• Caddy (main reverse proxy via DashCaddy)
• Tailscale network for secure node access

Prerequisites

1. Mazacoin Node running on 100.85.236.10 (Windows PC)

   • Wallet path: E:\coins\MAZA
   • CLI: E:\coins\MAZA\daemon\maza-cli.exe
   • SSH access configured with key at ~/.ssh/krystie_to_sami_pc

2. Docker and docker-compose installed

3. DashCaddy running on DNS1 (100.71.97.12)

Quick Start

1. Start the Mazacoin Node

On the Windows PC (100.85.236.10):

# Option 1: GUI with RPC enabled
E:\coins\MAZA\maza-qt.exe -server

# Option 2: Check if daemon exists and use it
E:\coins\MAZA\daemon\mazacoind.exe -daemon

2. Build and Deploy

cd /root/Projects/mazacoin-explorer
./deploy.sh

The deployment script will:

• Build Docker images
• Start frontend and backend containers
• Configure Caddy reverse proxy
• Make the explorer available at https://maza.samiahmed7777.me

3. Manual Deployment (Alternative)

# Build images
docker-compose build

# Start services
docker-compose up -d

# Check logs
docker-compose logs -f

Development

Backend Development

cd backend
npm install
npm run dev  # Uses nodemon for auto-restart

Frontend Development

cd frontend
npm install
npm start  # Runs on http://localhost:3001

Note: Update .env or src/config.js to point to your local backend during development.

API Endpoints

Blockchain Data

• GET /api/health - Health check
• GET /api/blockcount - Latest block height
• GET /api/block/:hashOrHeight - Get block by hash or height
• GET /api/tx/:txid - Get transaction by ID
• GET /api/blocks/latest/:count - Get latest N blocks
• GET /api/search/:query - Universal search

Network Info

• GET /api/stats - Network statistics
• GET /api/peers - Connected peer nodes (for node map)

WebSocket Events

• subscribe:blocks - Subscribe to new block notifications
• block:new - Receive new block events
• block:height - Current block height

Configuration

Backend Environment Variables

Create backend/.env:

NODE_ENV=production
PORT=3000
SSH_KEY_PATH=/root/.ssh/krystie_to_sami_pc

Frontend Environment Variables

Create frontend/.env:

REACT_APP_API_URL=https://maza.samiahmed7777.me

Monitoring

View Logs

# Backend logs
docker-compose logs -f backend

# Frontend logs
docker-compose logs -f frontend

# All logs
docker-compose logs -f

Check Service Status

docker-compose ps

Restart Services

# Restart all
docker-compose restart

# Restart specific service
docker-compose restart backend
docker-compose restart frontend

Troubleshooting

Backend can't connect to Mazacoin node

1. Check if Mazacoin is running on sami-pc:

ssh -i ~/.ssh/krystie_to_sami_pc hello@100.85.236.10 "tasklist | findstr maza"

2. Test RPC connection:

ssh -i ~/.ssh/krystie_to_sami_pc hello@100.85.236.10 "E:\coins\MAZA\daemon\maza-cli.exe getblockcount"

3. Check backend logs:

docker-compose logs backend | grep -i error

Frontend shows "API Error"

1. Check if backend is running:

curl http://localhost:3000/api/health

2. Check frontend logs for configuration issues:

docker-compose logs frontend

Node map not showing nodes

The node map requires:

1. Mazacoin node to have active peer connections
2. Internet access for IP geolocation API calls
3. May take a few minutes to geolocate all peers

Future Enhancements

• MongoDB integration for blockchain data caching
• Full address balance lookup (requires txindex)
• Transaction mempool viewer
• Charts for hashrate/difficulty trends
• Rich list (top addresses by balance)
• Mining pool statistics
• Block time analysis
• API rate limiting
• Prometheus metrics export
• Mobile app (React Native)
