🧱 What is Bitaxe? Solo Mining Bitcoin with Open-Source Hardware

Bitcoin mining has come a long way from being a hobby you could do on a home computer. These days, it’s dominated by large industrial operations using specialized hardware (ASICs) in massive data centers. But Bitaxe is changing that—bringing mining back into the hands of hobbyists, tinkerers, and DIYers.

In this post, we’ll explore what Bitaxe is, how its open-source design empowers the community, and how you can use it for a small but real chance to solo mine a Bitcoin block.

🔧 What is Bitaxe?

Bitaxe is a fully open-source, compact Bitcoin ASIC miner that can mine completely on its own—no external computer required. It’s powered by an ESP32 microcontroller and a single Bitcoin mining ASIC chip (like the BM1397 or BM1398), and it connects to Wi-Fi to fetch mining jobs over the internet.

Bitaxe is different from industrial miners in a few key ways:

  • ✅ Wi-Fi enabled and self-contained

  • ✅ Open-source hardware and firmware

  • ✅ Low power consumption

  • ✅ Built for learning, experimenting, and fun

  • ✅ Supports solo mining

While Bitaxe won’t win a hashpower race with industrial miners, it’s a great way to contribute to the decentralization of Bitcoin mining—and you could get lucky and win a block reward.

💡 Open-Source by Design

Bitaxe was created with openness at its core:

  • 🧩 Hardware schematics are freely available—anyone can build, modify, or improve the design.

  • 🖥️ Firmware is open and available on GitHub for community development.

  • 🔄 Community-driven development encourages hardware hackers and software developers to collaborate.

This means you’re not locked into a proprietary ecosystem. You can:

  • Modify the firmware.

  • Build your own version of the hardware.

  • Contribute code.

  • Learn how Bitcoin mining actually works—down to the silicon.

⚡ How to Use Bitaxe for Solo Mining

Yes—it’s possible to solo mine a block using Bitaxe. It’s rare, but it happens. Here’s how:

1. 🛠️ Flash Firmware & Connect

  • Most Bitaxe devices come pre-flashed.

  • Power it on and connect to its Wi-Fi hotspot.

  • Go to 192.168.4.1 in a browser.

2. 🌐 Set Wi-Fi & Pool Info

There are two solo mining options:

Option A: Mine Solo with Your Own Bitcoin Node

  • Run a fully synced Bitcoin Core node with txindex=1.

  • Set up a solo stratum proxy (like ckpool solo).

  • In Bitaxe’s config, set:

    • Pool: 127.0.0.1

    • Port: Your proxy’s port (e.g., 3333)

    • Username: Your Bitcoin address

Option B: Use a Public Solo Pool (e.g. solo.ckpool.org)

  • In Bitaxe’s config:

    • Pool: solo.ckpool.org

    • Port: 3333

    • Username: Your Bitcoin address

    • Password: x

3. 🚀 Start Mining

Once configured, reboot Bitaxe. It connects and starts hashing on its own.

If you're mining with a public solo pool like solo.ckpool.org, you can track your stats by visiting:

🎯 Can You Really Mine a Bitcoin Block with Bitaxe?

Yes, but let’s be honest: the odds are very low. Bitaxe hashes at around 300–500 MH/s depending on the model and chip used. That’s a tiny fraction of the Bitcoin network’s total hashrate. However, since Bitcoin is probabilistic, you still have a non-zero chance of finding a block.

Here’s why some still do it:

  • ❤️ For the love of tinkering

  • 🧠 To learn how mining works

  • 🧱 To support decentralization

  • 🤑 For the very small chance of winning 6.25 BTC (plus fees!)

🧠 Final Thoughts

Bitaxe is a fascinating open-source project that brings Bitcoin mining back to the individual. Whether you’re a developer, a hardware hacker, or just someone curious about how mining works, Bitaxe gives you a real, hands-on way to participate in the Bitcoin network—on your own terms.

While you may not strike gold, you’ll definitely gain knowledge—and maybe even inspire others to help keep Bitcoin decentralized.

Let me know if you'd like a downloadable version, images, or a code snippet to embed Bitaxe stats on a personal website.
