Open-Source Mining Firmware
The software powering these devices is as important as the hardware. Here are the key firmware projects in the ecosystem.
ESP-Miner / AxeOS
Open-source mining firmware used by Bitaxe models and several NerdAxe variants. ESP32-S3 based with web UI (AxeOS), Stratum V1, OTA updates, and support for BM1397, BM1366, BM1368, and BM1370 chips.
GitHub →DCENT_OS D-Central
D-Central firmware work built around Rust and Buildroot Linux. Source, license, supported hardware, and release status should be checked on the project page before deployment.
Learn More →Mujina
Next-generation mining firmware from the 256 Foundation. Multi-driver support (Antminer, Whatsminer, Avalon), Stratum V2, hot-swappable hashboards. Designed for the Ember One but aims for universal compatibility.
GitHub →Getting Started with Open-Source Mining
New to open-source Bitcoin mining? Here is how to get started in four steps.
Choose Your Device
For beginners, we recommend the BitAxe Gamma (~$80, 1.2 TH/s) or BitAxe Supra (~$70, 700 GH/s). Both are single-chip, 5V powered, and dead simple to set up.
Power & Connect
Plug in a 5V power supply (barrel jack, NOT USB-C). The device creates a WiFi hotspot — connect and enter your home WiFi credentials through the AxeOS web interface.
Configure Mining
Enter your Bitcoin address and choose a pool. For solo mining: public-pool.io or solo.ckpool.org. For pooled mining: any Stratum V1 pool works.
Mine & Learn
Your miner starts hashing after WiFi and pool configuration. Monitor the web UI, learn about difficulty and nonces, and treat solo mining as an educational probability experiment rather than a predictable income source.
Directory Methodology
This directory separates hardware source availability from firmware source availability. Hashrate, power, efficiency, and price ranges are treated as reference values because open-source builds can vary by board revision, cooling, tuning, firmware version, and power supply.
Frequently Asked Questions
What is an open-source Bitcoin miner?
An open-source Bitcoin miner is mining hardware whose design files, firmware source code, or both are publicly available under an open license such as GPL. Availability differs by project: some publish PCB files and firmware, while others only run open firmware.
Can I actually mine Bitcoin with a BitAxe or NerdMiner?
Yes, but expectations matter. A BitAxe Gamma (1.2 TH/s) does real SHA-256 hashing and can find a block solo — 5 blocks have been found by open-source miners. However, at current network difficulty, the statistical average solo time is thousands of years per device. Most users mine in pools for steady (tiny) payouts or solo mine for the lottery-ticket experience. A NerdMiner (~1 MH/s) is purely educational — real block-finding odds are essentially zero.
What is the difference between BitAxe and NerdAxe?
Bitaxe is an open-source ASIC miner family with models from hundreds of GH/s to multi-TH/s, typically running AxeOS firmware. NerdAxe is a parallel ecosystem that includes the NerdMiner educational device and ASIC-equipped variants like NerdQAxe and NerdOctaxe. License coverage and source availability should be checked per model.
What ASIC chip should I look for?
The BM1370 is used in newer open-source miner designs and can reach roughly 15 J/TH in tuned builds. BM1368 and BM1366 designs are common mid-range options. Legacy BM1397 devices can still be educational but are less efficient.
Is the Lucky Miner open-source?
Partially. Lucky Miner devices run ESP-Miner firmware (which is open-source GPL), but the hardware design itself is proprietary — PCB files are not publicly available. This means you get open firmware benefits (community updates, no vendor lock-in) but cannot build or modify the hardware independently.
What is the Ember One?
The Ember One is an open-source hashboard from the 256 Foundation, not a standalone miner. It uses 12 BM1362 chips and needs a separate USB control board such as Libre Board or a Raspberry Pi to operate.
Does D-Central sell open-source miners?
Yes. D-Central Technologies sells Bitaxe models and accessories, and publishes project pages for firmware work such as DCENT_OS. Check each product or project page for current inventory, source links, and support status.
What firmware do open-source miners run?
Most open-source miners run ESP-Miner (also called AxeOS) — a C-based firmware on ESP32-S3 microcontrollers. It provides a web UI for configuration, Stratum V1 pool support, OTA updates, and supports all BM13xx chips. D-Central is developing DCENT_OS in Rust as an alternative for both USB miners and full-size ASICs.
