How The Bitforge Nano Works

Bitforge Nano Overview

At its core, the BitForge Nano uses dual BM1370 ASIC chips , the same chips used in industrial mining equipment but configured for home use. These factory-new chips, work in tandem to deliver a combined hashrate that significantly exceeds single-chip alternatives like the Bitaxe Supra and Gamma.

BM1370, the heart of the BitForge Nano

The device is controlled by an ESP32-S3 microcontroller, which manages the mining operations and provides a fast, stable Wi-Fi connection. This removes the need for ethernet cables, making the setup remarkably clean and flexible. You can place the Bitforge Nano anywhere within Wi-Fi range without worrying about running network cables across your space.

Once powered on with the included power supply, the miner connects to your network and presents a user-friendly web interface through BitForgeOS. From this interface, you can configure your mining pool, adjust performance settings, and monitor your device's statistics, all without needing to install additional software on your computer.

The Bitforge Nano offers three distinct performance profiles, allowing you to balance hashrate against power consumption and heat output based on your preferences. Out of the box, it runs at 2.4 TH/s at medium mode, but you can adjust this from 2 TH/s for quieter, cooler operation, and up to 2.6 TH/s for maximum performance (though overclocking beyond manufacturer specifications voids the warranty).

For those interested in solo mining, attempting to find Bitcoin blocks independently rather than joining a pool, the Bitforge Nano makes this accessible. Based on 2026 stats, if approximately 50,000 Bitforge Nanos are operating worldwide at 2.6 TH/s each, the average time to find a block would be around 57 days. While this is a lottery-style approach to mining, it supports Bitcoin's decentralization and gives home miners a chance, however small, at the full block reward.

Bitforge Nano Features

Bitforge Nano Technical Specifications

Dual BM1370 ASIC Chips The defining feature of the Bitforge Nano is its dual-chip configuration. Using only factory-new BM1370 chips, the device achieves performance levels previously unavailable in the home mining segment. This dual-chip approach is what enables up to 2.6 TH/s hashrate that doubles the output of comparable single-chip devices.

Advanced Cooling System The engineers behind the Bitforge Nano developed a specialized heat sink specifically for this device. The cooling concept uses two fans to create optimal airflow, with parallel cooling of the voltage regulator to ensure every component stays within safe operating temperatures. This perfected cooling design allows the dual chips to run efficiently while keeping noise levels reasonable and preventing thermal throttling that could reduce performance.

Custom 3D-Printed Housing The housing isn't just functional, it's been designed to look professional and blend into home or office environments. The 3D-printed case is sturdy enough to protect the components while maintaining a compact footprint that won't dominate your desk or shelf.

Integrated Wi-Fi Thanks to the ESP32-S3 microcontroller, the Bitforge Nano connects wirelessly to your network. This space-saving feature eliminates cable clutter and gives you flexibility in placement. Setup takes just minutes through the web interface, no technical expertise required.

Open-Source Firmware and Hardware Both the BitForgeOS firmware and the hardware designs are open-source and available through the official GitHub repository. This means you can examine the code, suggest improvements, contribute to development, or modify the software to suit your specific needs. The open-source nature also ensures transparency and allows the community to audit security and performance continuously.

Three Performance Modes Choose between efficiency and power:

• Eco mode: 2 TH/s for minimal power consumption and noise
• Standard mode: 2.2 TH/s out-of-the-box performance
• Performance mode: 2.6 TH/s for maximum hashrate

Simple Operation There's no display, no buttons to fumble with, and no complex menus. The Bitforge Nano is operated exclusively through the clean, intuitive ForgeOS web interface accessible from any device on your network.

CE Certification The device meets European safety standards, providing peace of mind that it's been tested and approved for home use.

Improvements Compared To The Previous Generation

When compared to the Bitaxe Gamma, one of the most popular home mining devices on the market, the Bitforge Nano represents a substantial leap forward in several key areas.

Hashrate Performance The most obvious improvement is hashrate. While the Bitaxe Gamma delivers a respectable single-chip performance, the Bitforge Nano's dual BM1370 configuration produces up to 2.6 TH/s out of the box, more than double the Gamma's output. This isn't just a minor incremental improvement; it's a fundamental shift in what's possible for home miners. The ability to scale up to 2.6 TH/s in performance mode pushes this advantage even further.

Efficiency Despite doubling the hashrate, the Bitforge Nano maintains excellent efficiency at 15 J/TH according to chip specifications. This means you're getting significantly more mining power without a proportional increase in your electricity bill. The Bitaxe Gamma is efficient for a single-chip device, but the Bitforge Nano's dual-chip optimization and advanced cooling system allow it to operate at competitive efficiency levels while delivering far more performance.

Cooling and Noise The specially developed heat sink and dual-fan cooling system in the Bitforge Nano represents a significant engineering improvement. While the Bitaxe Gamma can run warm and occasionally loud under stress, the Bitforge Nano's perfected cooling concept with parallel voltage regulator cooling ensures optimal heat dissipation across all components. This results in more stable performance and quieter operation, even when pushing the device to its limits.

Form Factor and Aesthetics The Bitaxe Gamma has an open, exposed design that showcases its components but can look industrial. The Bitforge Nano's custom 3D-printed box housing offers a more refined, professional appearance that's designed to blend into home and office environments. This might seem superficial, but for devices meant to run 24/7 in living spaces, aesthetics matter.

Market Positioning The Bitforge Nano holds the distinction of being the first dual-chip ASIC miner on the market. This isn't just a marketing claim, it represents genuine innovation in the home mining space. While the Bitaxe Gamma proved that home mining could be accessible and efficient, the Bitforge Nano proves it can also be powerful.

Setup and Management Both devices offer web-based interfaces, but the Bitforge Nano's ForgeOS has been developed specifically for dual-chip management and offers three distinct performance profiles out of the box. The ESP32-S3 microcontroller provides faster processing and more reliable Wi-Fi connectivity than previous generation controllers.
