# RIN Stratum Proxy - Node.js Implementation
|
|
|
|
This is a **production-ready** Node.js-based stratum proxy server for RIN Coin mining. It provides complete block validation, hash calculation, and block submission to the RIN network. This implementation replaces the lost custom proxy with a fully functional mining proxy.
|
|
|
|
## 🚀 Features
|
|
|
|
- **Full Stratum Protocol Support**: Complete Stratum mining protocol implementation
|
|
- **RIN RPC Integration**: Direct connection to RIN node for block templates and submissions
|
|
- **Complete Block Validation**: Full coinbase transaction building, merkle root calculation, and block hash validation
|
|
- **Production-Ready Hash Validation**: Proper SHA256 double hashing and target comparison
|
|
- **Real-time Job Updates**: Automatically fetches new block templates from RIN node
|
|
- **Block Submission**: Validates shares and submits valid blocks to RIN network
|
|
- **Progress Monitoring**: Shows mining progress as percentage of network difficulty
|
|
- **Comprehensive Logging**: Detailed share validation and block submission logs
|
|
- **Large Mining Rig Support**: Handles multiple concurrent miners efficiently
|

|
## 🔧 Installation
|
|
|
|
### Prerequisites
|
|
|
|
- **Node.js**: Version 14 or higher
|
|
- **npm**: Node package manager
|
|
- **RIN Node**: Running RIN node with RPC enabled on port 9556
|
|
|
|
### Setup
|
|
|
|
1. **Navigate to the proxy directory**:
|
|
```bash
|
|
cd /mnt/shared/DEV/repos/d-popov.com/mines/rin/proxy/node-stratum-proxy
|
|
```
|
|
|
|
2. **Install dependencies**:
|
|
```bash
|
|
npm install
|
|
```
|
|
|
|
3. **Make scripts executable**:
|
|
```bash
|
|
chmod +x start_proxy.sh test-client.js
|
|
```
|
|
|
|
## 🚀 Usage
|
|
|
|
### Start the Stratum Proxy
|
|
|
|
```bash
|
|
./start_proxy.sh
|
|
```
|
|
|
|
The startup script will:
|
|
- Check Node.js and npm installation
|
|
- Install dependencies if needed
|
|
- Verify RIN node connectivity
|
|
- Start the stratum proxy server
|
|
|
|
### Connect Miners
|
|
|
|
Once the proxy is running, connect miners using:
|
|
|
|
```bash
|
|
# CPU Miner
|
|
./cpuminer -a rinhash -o stratum+tcp://127.0.0.1:3333 -u worker1 -p x -t 4
|
|
|
|
# GPU Miner (if available)
|
|
./rinhash-gpu-miner -o stratum+tcp://127.0.0.1:3333 -u worker1 -p x
|
|
```
|
|
|
|
### Test the Proxy
|
|
|
|
Run the test client to verify proxy functionality:
|
|
|
|
```bash
|
|
node test-client.js
|
|
```
|
|
|
|
## ⚙️ Configuration
|
|
|
|
Edit `server.js` to modify configuration:
|
|
|
|
```javascript
|
|
const CONFIG = {
|
|
// Stratum server settings
|
|
stratum: {
|
|
host: '0.0.0.0', // Listen on all interfaces
|
|
port: 3333, // Stratum port
|
|
difficulty: 0.00001 // Mining difficulty
|
|
},
|
|
|
|
// RIN RPC settings
|
|
rpc: {
|
|
host: '127.0.0.1', // RIN node host
|
|
port: 9556, // RIN node RPC port
|
|
user: 'rinrpc', // RPC username
|
|
password: '745ce784d5d537fc06105a1b935b7657903cfc71a5fb3b90' // RPC password
|
|
},
|
|
|
|
// Mining settings
|
|
mining: {
|
|
targetAddress: 'rin1qahvvv9d5f3443wtckeqavwp9950wacxfmwv20q', // Mining address
|
|
extranonceSize: 4, // Extranonce2 size in bytes
|
|
jobUpdateInterval: 30000 // Job update interval (ms)
|
|
}
|
|
};
|
|
```
|
|
|
|
## 🔍 Debugging
|
|
|
|
Enable debug logging:
|
|
|
|
```bash
|
|
DEBUG=stratum node server.js
|
|
```
|
|
|
|
This will show detailed stratum protocol messages and RPC communications.
|
|
|
|
## 📊 Monitoring
|
|
|
|
The proxy provides real-time logging:

|
## 🔄 How It Works
|
|
|
|
1. **Server Startup**:
|
|
- Connects to RIN RPC node
|
|
- Fetches initial block template
|
|
- Starts stratum server on port 3333
|
|
|
|
2. **Miner Connection**:
|
|
- Miner connects via Stratum protocol
|
|
- Server sends subscription response with extranonce1
|
|
- Server sends initial mining job
|
|
|
|
3. **Job Management**:
|
|
- Server periodically fetches new block templates
|
|
- Broadcasts new jobs to all connected miners
|
|
- Handles share submissions from miners
|
|
|
|
4. **Share Processing**:
|
|
- Validates share against current job
|
|
- Calculates block hash and difficulty
|
|
- Submits valid blocks to RIN network
|
|

## 🐛 Troubleshooting
|
|
|
|
### Common Issues
|
|
|
|
1. **"Failed to connect to RIN node"**
|
|
- Ensure RIN node is running: `rincoind -server=1 -rpcuser=rinrpc -rpcpassword=...`
|
|
- Check RPC port (9556) is accessible
|
|
- Verify RPC credentials
|
|
|
|
2. **"Module not found: stratum"**
|
|
- Run `npm install` to install dependencies
|
|
- Check Node.js version (14+ required)
|
|
|
|
3. **"Address already in use"**
|
|
- Port 3333 is already in use
|
|
- Change port in CONFIG or kill existing process
|
|
|
|
### Debug Commands
|
|
|
|
```bash
|
|
# Check RIN node status
|
|
curl -u rinrpc:745ce784d5d537fc06105a1b935b7657903cfc71a5fb3b90 \
