Texas. I’m so back. image
Two open-source bitcoin mining control boards now exist. But why two? 🤔👇 We open sourced BCB100 in January. Then 256 Foundation announced their own FOSS board project. I was confused. Why not build on top of ours? They said their goals were different. That it’s easier to start from scratch… And now that we’ve seen more details, IT MAKES SENSE. Two boards. Two directions. BCB100 (by Braiins) 🟠 Built for industrial-scale uptime 🟠 Plug-and-play with any S19 miner 🟠 Tested in harsh real-world environments 🟠 Easily adaptable for new industrial models (e.g. swap fan connectors for S21 series) Libre Board (by 256 Foundation) 🔸 Built for home mining and DIY projects 🔸 Based on Raspberry Pi Compute Module (CM), modular and easy to expand 🔸 USB-C and WiFi support, great for small home setups 🔸 Ideal for tinkerers building heaters, automation, or custom rigs 🔸 Not built for high-density or industrial use The design focus is what separates them. Adapting Libre for industrial use is possible but not practical. Adapting BCB100 for new industrial use cases is faster and requires fewer changes. TWO BOARDS. TWO USE CASES. BOTH OPEN 🔥 Choose what fits. Let’s build! image
I’m visiting the Lucky Miner factory in China this week. Got any questions or messages for the guy behind this closed-source Bitaxe clone? I’ll report back 👇 image
This illegal Bitaxe clone is quietly dominating Asia. Today I had lunch with the guy behind it 👇 He’s a young bitcoin entrepreneur from Shenzhen, China. Quiet, humble—but running a serious operation: large-scale self-mining, hosting, and full-scale manufacturing of mining hardware and spare parts. He’s been in the space since 2017. Genuinely believes in bitcoin’s mission. LuckyMiner started as a hobby in late 2023. He said he wanted to help more people get into mining—not really to make a profit. But in early 2024 the demand exploded. Thousands sold. BREAKING THE LICENSE. Bitaxe is open source under CERN-OHL-S-2.0—which means any modifications must be published. So why do it? I asked him directly. He didn’t get angry or defensive. He said: 1️⃣ Retail customers in Asia don’t care about open source, and the Bitaxe brand isn’t suited for the local market 2️⃣ His team is juggling too many projects—releasing modifications is low priority. Their time is too valuable Not great reasons—but they felt honest. 👉 Legit Bitaxes: They now manufacture open-source Bitaxes too—but only for B2B clients, fully license-compliant. LuckyMiners are sold direct to retail customers. 👉 Copying Braiins: They copied us too—and admitted it to my face. But that’s a story for next time. Follow me so you don’t miss it 😆 What’s next? As sales kept growing, they added a Litecoin version earlier this year. And they plan to keep expanding—with more form factors and higher production volumes. But he says chip availability is the biggest bottleneck. CHIPS ARE THE PROBLEM. Everywhere. Or rather—not having chips available for purchase is the story here for me. Hope we find a solution. Anyways… I don’t support his decisions. But I have to admit—he’s a really nice guy, bitcoiner at heart, and I appreciated his honest answer and perspective on the Asian market. Now you know the story behind the most controversial mini-miner on the market. Curious to hear your thoughts. image
Wife: “your solo bitcoin mining is killing our electricity bill” Me: “Say no more” image
We’ve just open sourced the BCB100 on GitHub 🔥 The Braiins Control Board is now officially the Bitcoin Control Board. Everything you need to build is now available: — OpenWrt-based firmware with full config — Hardware design files: BOM, schematics, Gerbers, CAD — Nix environment for reproducible builds — Mining binaries (bosminer, boser), same as in official Braiins OS releases Repository: 🔗 Full README with docs, files, and build scripts is on our GitHub. Licenses: 🔶 Software — GPLv3 🔶 Hardware — CERN-OHL-S 🔶 Mining components — binary-only Test units: ✅ We’re sending a few BCB100 boards to Bitcoin Park in Nashville for builders to explore and experiment. ✅ A few units will also be available soon on the Braiins Store, shipping fast from our US and EU warehouses with no customs hassle. Bitcoin mining infrastructure needs more transparency and resilience. This is how we help accelerate that mission 🫡 Let’s build. image
Six years ago I quit KPMG. Today I drove a Mustang through beautiful Oklahoma to a horse ranch where they mine bitcoin with flare gas and made another bitcoin video. This is my job now. Quit fiat. Join bitcoin. There is no second best. image
This is our non-Chinese bitcoin mining chip. And it’s a way bigger deal than you think 👇 Six years ago, when I joined Braiins, we had a mining pool. The world’s first. Then we launched custom firmware—now powering gigawatts of miners worldwide. Last year we dropped Braiins Manager. A cloud platform giving miners full control over their farms. BUT THE BIGGEST ISSUE REMAINED UNTOUCHED Hardware centralization. For years, Bitmain has controlled over 70% of the global market. And we’ve been loud about the need for competition. So instead of waiting, we built. This week, Braiins Bitcoin Silicon arrived in our Prague office. Our first test ASIC chips. 🫡 2.5 years of hardcore R&D. 🚀 Big skin in the game (shoutout to Firefish for helping us collateralize—not sell—our bitcoin 🧡). Exciting times, BUT… The work is just beginning. And it must be done. Join our mission! image
