How to Mine Bitcoin2 (BC2) on Windows Using Bitaxe and a Self-Hosted Node

4 min readJan 23, 2026

Introduction

This guide explains how to set up your own Stratum server to solo mine Bitcoin2 (BC2) with your Bitaxe Gamma (or any other Stratum-compatible ASIC miner).

Benefits of solo mining:

No pool fees (100% of rewards for you)

Full control over your mining operation

Support the network by validating transactions

Complete learning experience

Requirements

A Windows/Linux PC with Python 3.7+

A Bitaxe (Gamma, Supra, Ultra, or other Stratum ASIC)

Bitcoin2-qt (BC2 full node wallet)

Stable network connection

Step 1: Installing Bitcoin2-qt

Download

1.Visit the official Bitcoin2 website or GitHub repository

2.Download Bitcoin2-qt (bitcoinII-qt)

3.https://github.com/Bitcoin-II/BitcoinII-Core/releases/download/v29.1.0/BitcoinII-29.1.0-x86_64-win64-GUI.zip

4.Install the application

Synchronization

Important: Let the node fully synchronize with the BC2 network. This may take several hours depending on your connection speed.

Step 2: Configuring Bitcoin2-qt

First go on the node app then settings, make sure server rpc is checked else do it.

Locate the configuration file

Windows: %APPDATA%\BitcoinII\bitcoinII.conf

Windows： %APPDATA%\BitcoinII\bitcoinII.conf

Linux: ~/.bitcoinII/bitcoinII.conf

Linux：~/.bitcoinII/bitcoinII.conf

If the file doesn’t exist, create it.

Add these lines

ini

PlainBashC++C#CSSDiffHTML/XMLJavaJavaScriptMarkdownPHPPythonRubySQL

server=1

rpcuser=your_rpc_username

rpcpassword=your_secure_rpc_password

rpcallowip=127.0.0.1

rpcport=8332

Tip: Use a strong, unique password!

Restart Bitcoin2-qt

Completely close the application and restart it to apply the changes.

Step 3: Installing Python

If you don’t have Python

Windows:

1.Download Python from python.org

2.Check “Add Python to PATH” during installation

3.Verify: open CMD and type python --version

Install dependencies

Open a terminal/command prompt and type:

bash

PlainBashC++C#CSSDiffHTML/XMLJavaJavaScriptMarkdownPHPPythonRubySQL

pip install requests

Step 4: The Python Script

Create the file

Create a file named bc2_stratum_server.py and copy the script provided below.

https://pastebin.com/R8zHFM2J

Configure the script

Modify these lines at the beginning of the script according to your setup:

python

PlainBashC++C#CSSDiffHTML/XMLJavaJavaScriptMarkdownPHPPythonRubySQL

RPC_USER = “your_rpc_username”

# Same as bitcoinII.conf

RPC_PASSWORD = “your_rpc_password”

# Same as bitcoinII.conf

RPC_PORT = 8332

# RPC port (usually 8332)

STRATUM_PORT = 3333

# Port for your Bitaxe

Vardiff parameters (optional)

You can adjust the variable difficulty:

python

PlainBashC++C#CSSDiffHTML/XMLJavaJavaScriptMarkdownPHPPythonRubySQL

TARGET_SHARE_TIME = 15

# Shares every 15 seconds (adjust to preference)

VARDIFF_MIN = 100

# Minimum difficulty

VARDIFF_MAX = 100000

# Maximum difficulty

Step 5: Launch the Stratum Server

Windows

1.Open Command Prompt (CMD)

2.Navigate to the script folder: cd C:\path\to\script

3.Run: python bc2_stratum_server.py

You should see

🔍 Testing connection to Bitcoin2 node…

✅ Connection to node successful!

Blocks: 50303

Version: 290100

Connections: 7

✅ Stratum server started on 0.0.0.0:3333

📡 Configure your Bitaxe Gamma with:

URL: stratum+tcp://192.168.1.12:3333

User: bc2miner

Password: x

⏳ Waiting for connection…

Step 6: Configure Your Bitaxe

Access the web interface

1.Find your Bitaxe’s IP (check your router)

2.Open a browser: http://[BITAXE_IP]

Pool configuration

In the Bitaxe interface, configure:

URL: stratum+tcp://[YOUR_PC_IP]:3333

User: bc2miner (or any name)

Password: x (or anything)

Find your PC’s IP:

Windows: ipconfig in CMD

Linux: ip addr or ifconfig

Save and restart

The Bitaxe should connect within seconds!

Step 7: Firewall Configuration

Windows Defender

If your Bitaxe won’t connect:

1.Open Windows Firewall (Windows key + R → wf.msc)

2.Inbound Rules → New Rule

3.Type: Port

4.TCP, port: 3333

5.Allow the connection

6.All profiles

7.Name: “Bitcoin2 Stratum Server”

Avast / Other antivirus

Add an exception for:

The Python script (bc2_stratum_server.py)

Or TCP port 3333

Verification

In the Python terminal

You should see:

PlainBashC++C#CSSDiffHTML/XMLJavaJavaScriptMarkdownPHPPythonRubySQL

🔌 New connection detected: (192.168.1.25, 51234)

✅ Worker authorized: bc2miner.BigAxe

📤 Job 1 sent to 192.168.1.25:51234

✨ Share #1 from bc2miner.BigAxe (Diff: 1000) — Avg time: 12.3s

🎯 Difficulty adjustment for bc2miner.BigAxe:

1000 → 1500 (avg time: 10.2s, target: 15s)

On the Bitaxe interface

Hashrate: ~1.2 TH/s (Gamma)
Shares: Increasing regularly
Block Header: Shows Height, Difficulty, Scriptsig
Status: Connected

🎁 If You Find a Block

Rewards will go directly to your Bitcoin2-qt wallet!

With current difficulty (~38 billion) and a Bitaxe Gamma (~1.2 TH/s), finding a block may take years, but it’s possible! 🍀

🔧 Troubleshooting

Script won’t start

✅ Verify Bitcoin2-qt is running
✅ Check RPC credentials in bitcoinII.conf
✅ Verify Python and requests are installed

Bitaxe won’t connect

✅ Check your PC’s IP address
✅ Temporarily disable firewall to test
✅ Verify port 3333 isn’t in use: netstat -an | findstr :3333

No shares

✅ Is the Bitaxe properly configured?
✅ Check Python script logs
✅ Restart the Bitaxe

“HTTP 401” error

✅ RPC credentials don’t match
✅ Check bitcoinII.conf and Python script
✅ Restart Bitcoin2-qt after modifications

📊 Statistics and Monitoring

The script displays in real-time:

✨ Accepted shares with average time
🎯 Automatic difficulty adjustments
🔄 New blocks detected on the network
📋 Jobs sent to Bitaxe

💡 Tips

Run 24/7 to maximize your chances
Monitor temperature of your Bitaxe
Backup your wallet regularly
