NerdQAxe++ Setup Guide: Quad-Chip Open-Source Mining Device Configuration

What Is the NerdQAxe++?

The NerdQAxe++ is a quad-chip open-source Bitcoin solo miner built around four BM1370 ASIC chips — the same silicon powering Bitmain’s flagship Antminer S21 Pro. With four chips working in parallel, the NerdQAxe++ delivers 4.8 TH/s at stock and up to 6.0 TH/s on the current Rev 6.1 default settings, all from a device that fits in the palm of your hand and draws roughly 100W. This is not a toy. This is a serious solo mining machine.

How serious? On January 2025, a solo miner running six NerdQAxe++ units found Block #920,440 — a full Bitcoin block worth 3.15 BTC (~$342,000 USD) at the time. One person, six open-source miners on a desk, and the entire block reward. That is the promise of solo mining made real. That is what the NerdQAxe++ is built for.

The NerdQAxe++ runs AxeOS (ESP-Miner firmware) on an ESP32-S3 controller, features a LILYGO T-Display S3 color LCD for real-time stats, and connects over WiFi for completely standalone operation. No computer needed, no cloud accounts, no middlemen — just plug in power, configure your pool and Bitcoin address, and start hashing. Every unit D-Central sells is hand-assembled and tested in our workshop in Laval, Quebec. We do not dropship from anonymous factories. We build these, we test these, and we stand behind every one.

This guide walks you through complete setup of your NerdQAxe++ from unboxing to your first submitted share. Whether this is your first open-source miner (see our Getting Started guide) or you are expanding a fleet, we cover every detail specific to the NerdQAxe++ Rev 6.1.

Technical Specifications

The NerdQAxe++ Rev 6.1 is a significant step up from single-chip Bitaxe devices. Four BM1370 chips working together deliver terahash-class performance in a compact, quiet, power-efficient package.

NerdQAxe++ vs. Bitaxe Variants

The NerdQAxe++ occupies a unique position in the open-source miner landscape — far more powerful than any single-chip Bitaxe, but still compact and quiet enough for your desk. Here is how it compares:

At 6.0 TH/s, the NerdQAxe++ gives you roughly 10 to 12 times the solo mining odds of a Bitaxe Supra — and it proved those odds are real with Block #920,440. More chips, more hashrate, more lottery tickets every second.

What’s in the Box

When your NerdQAxe++ arrives from D-Central, inspect the package contents carefully before powering on.

• NerdQAxe++ Rev 6.1 board — Main PCB with four BM1370 ASIC chips, ESP32-S3 controller, and LILYGO T-Display S3 screen
• Spring-mounted heatsink assembly — Pre-installed or included, with spring-tension mounting for even pressure across all four ASIC chips
• Dual-fan cooling system — Two fans for active cooling across the heatsink assembly
• XT30 power cable — For connecting to your 12V DC power supply (verify connector compatibility with your PSU)

If anything is missing or appears damaged during shipping, contact D-Central support immediately. Every unit is individually tested before shipping, and we stand behind our work.

What You’ll Need

A note on Bitcoin wallet addresses: You need a valid Bitcoin address to receive mining rewards. This must be an address you fully control — from a hardware wallet like a Coldcard, Trezor, or BitBox, or a self-custody software wallet like Sparrow, Electrum, or BlueWallet. Do not use an exchange deposit address. If your NerdQAxe++ finds a block — and they have — you want that 3.125 BTC in a wallet where you hold the keys. Not your keys, not your coins.

Safety Warnings

Hardware Setup

The NerdQAxe++ arrives largely pre-assembled from D-Central. Your primary tasks are inspecting the unit, verifying the cooling system, and connecting power.

Step 1: Unboxing & Inspection

1. Remove the NerdQAxe++ from its packaging carefully. Hold the board by its edges — avoid touching the ASIC chips, heatsink thermal interface, or display connector directly.
2. Visually inspect the PCB — Look for any signs of shipping damage: bent components, cracked solder joints, or loose connectors. Pay special attention to the XT30 power connector and the display ribbon cable.
3. Check the LILYGO T-Display S3 — The 1.9″ color LCD should be securely mounted. Verify the ribbon cable is fully seated in its connector.
4. Verify all four ASIC chips are seated — You should see four BM1370 chips on the board, evenly spaced under the heatsink assembly.

Step 2: Inspect the Spring-Mounted Heatsink

The NerdQAxe++ uses a spring-mounted heatsink system that applies even pressure across all four BM1370 chips simultaneously. This is critical — uneven contact on a quad-chip board means some chips overheat while others stay cool, causing instability and reduced hashrate.

1. Check the spring tension — Gently press each corner of the heatsink. The springs should compress evenly and the heatsink should return to its resting position smoothly. If any spring feels loose or a mounting post is bent, contact D-Central support before powering on.
2. Verify thermal pad alignment — If you can see the edges of the thermal pad(s) between the heatsink and the ASIC chips, confirm they are centered and not folded or displaced. Each chip needs full thermal pad coverage.
3. Check the dual fans — Both fans should spin freely when rotated by hand (gentle finger push). Verify both fan cables are connected to their headers on the PCB. A disconnected fan means half your cooling is offline.

Step 3: Power Connection (XT30)

The NerdQAxe++ uses an XT30 connector for 12V DC power input — a significant departure from the 5V barrel jack used by single-chip Bitaxe devices. The XT30 is a compact, high-current connector commonly used in the RC hobby and 3D printing communities, rated for up to 30A continuous.

1. Verify your PSU output — Confirm your power supply outputs 12V DC at a minimum of 10A (120W). Check the label on your PSU for rated output specifications.
2. Inspect both XT30 connectors — Check the male connector on the NerdQAxe++ and the female connector on your power cable. Pins should be clean, straight, and free of corrosion.
3. Connect the XT30 plug firmly — The XT30 has a keyed design that only inserts one way. Push until you feel a solid click. A loose connection at 8+ amps will generate heat at the junction and potentially damage the connector.
4. Plug your PSU into a wall outlet — Use a surge protector rated for at least 150W. The NerdQAxe++ powers on automatically — there is no power button.

Step 4: Positioning

At 100W with active dual-fan cooling, placement matters. The NerdQAxe++ generates significantly more heat than a single-chip Bitaxe and needs proper airflow to maintain optimal temperatures.

• Flat, stable surface — Place the NerdQAxe++ on a hard, flat surface (desk, shelf, table). Avoid soft surfaces like carpet, fabric, or bedding that can block airflow underneath.
• Clear fan intake and exhaust — Leave at least 5 cm (2 inches) of clearance on the fan sides. The dual fans pull air across the heatsink — obstructed airflow leads to recirculation and rising temperatures.
• Away from heat sources — Do not place next to other miners, space heaters, or in direct sunlight. Ambient air temperature directly affects ASIC temperatures.
• Near your WiFi router — A strong 2.4 GHz signal means fewer disconnections. Walls and distance degrade WiFi quality for the ESP32-S3.
• Consider noise — At ~40 dB, the NerdQAxe++ is about the volume of a quiet conversation or a running refrigerator. Comfortable for a home office, but you may notice it in a silent bedroom. If noise is a concern, place it in a well-ventilated closet or utility room.

Initial Setup & WiFi Configuration

With the NerdQAxe++ powered on and the fans spinning, it is time to bring it online. The entire configuration process happens through your web browser via the AxeOS dashboard.

First Boot

When you connect the XT30 power cable and your PSU is plugged in, the NerdQAxe++ powers on immediately:

1. Both fans spin up — you should hear them engage within a second. If one or both fans do not spin, disconnect power immediately and inspect the fan connections.
2. The LILYGO T-Display S3 screen illuminates and shows the AxeOS boot sequence. After a few seconds, it will display basic status information (firmware version, WiFi status, etc.).
3. The ESP32-S3 LED on the controller module lights up, confirming the firmware is running.
4. After 15–30 seconds, AxeOS begins broadcasting its own WiFi access point for initial configuration.

Connect to AxeOS WiFi Access Point

On first boot (or when the NerdQAxe++ cannot connect to a saved WiFi network), AxeOS creates its own WiFi hotspot for configuration.

1. On your phone, laptop, or tablet, open your WiFi settings.
2. Look for a network named “AxeOS” or “AxeOS_XXXX” (where XXXX is a unique identifier). This is your NerdQAxe++ broadcasting its configuration network.
3. Connect to this network. No password is required on initial setup (some firmware versions may use “password” or “12345678” as the default — the display screen may show the password if one is set).
4. Your device may show a “no internet” warning — this is normal. You are connected directly to the NerdQAxe++, not to the internet.

Once connected, open your web browser and navigate to:

http://192.168.4.1

The AxeOS dashboard should load, showing the main configuration interface. You will see status panels for hashrate, temperature, pool connection, and system information.

Configure Your Home WiFi

Connect the NerdQAxe++ to your home WiFi network so it can reach the internet and communicate with your mining pool.

1. In the AxeOS dashboard, navigate to the WiFi / Network settings section.
2. Enter your WiFi network name (SSID) exactly as it appears — this is case-sensitive.
3. Enter your WiFi password.
4. Click Save. The NerdQAxe++ will reboot and attempt to connect to your home WiFi.

After rebooting, the NerdQAxe++ will stop broadcasting the AxeOS access point and join your home network. The T-Display screen will show “WiFi: Connected” with the assigned IP address once connected.

To access the AxeOS dashboard after WiFi configuration, find the NerdQAxe++ on your network:

• Check the T-Display screen — The easiest method. The screen shows the assigned IP address directly. No need to hunt through router settings.
• Check your router’s admin page — Look for a device named “AxeOS” or “ESP32” in the connected devices list.
• Use mDNS — Try navigating to:

http://axeos.local

• Use a network scanner — Apps like Fing (iOS/Android) or Advanced IP Scanner (Windows) will show all devices on your network.

Configure Mining Settings

Your NerdQAxe++ is connected to your WiFi network and you can reach the AxeOS dashboard. Now configure it to mine Bitcoin. This is where 6 TH/s starts working for you.

Choose Your Mining Pool

The NerdQAxe++ communicates with a mining pool using the Stratum protocol. Even for solo mining, you connect to a pool server that handles communication with the Bitcoin network.

Solo Mining (Lottery Mining) — Connect to a solo mining pool where every hash is your individual attempt at finding a full Bitcoin block. If your NerdQAxe++ finds a valid block, you keep the entire reward: 3.125 BTC. This is the most popular approach for NerdQAxe++ owners and the approach that found Block #920,440.

Pool Mining — Connect to a traditional pool where your hashrate is combined with other miners for small, regular payouts. At 6 TH/s, pool mining generates more meaningful payouts than a single-chip Bitaxe — roughly a few hundred satoshis per day depending on network difficulty and pool fees. Still small, but measurable.

For this guide, we set up solo mining — the reason most people buy a NerdQAxe++.

Enter Pool Settings

In the AxeOS dashboard, navigate to the Mining / Stratum configuration section. Enter the settings for your chosen solo mining pool:

Public Pool is the community standard — zero fees, open-source, built for small solo miners. It is our default recommendation.

Set Your Bitcoin Address

The Worker Name / Username field is where you enter your Bitcoin wallet address. On solo mining pools, your worker name IS your Bitcoin address — this is where the entire block reward goes if your NerdQAxe++ finds a block.

1. Open your Bitcoin wallet and copy a receive address. Use a bc1q (native SegWit) address for the lowest fees.
2. Paste the address into the Worker Name or Username field in AxeOS.
3. Optionally append a device identifier: bc1qyouraddresshere.nerdqaxe1 — this helps identify the device on the pool dashboard.
4. Set the Password field to x (or leave blank).
5. Click Save. The NerdQAxe++ will reboot and start mining within 30–60 seconds.

Fan Speed Tuning

The NerdQAxe++ dual-fan system is managed through AxeOS. You can adjust fan behavior to balance cooling performance against noise.

1. In the AxeOS dashboard, navigate to the Fans / Cooling settings.
2. Auto mode (recommended) — AxeOS adjusts fan speed dynamically based on ASIC temperature. Fans ramp up as temperature rises and slow down as it cools. This is the best setting for most users.
3. Manual mode — You can set a fixed fan speed percentage. Useful if you want to prioritize silence (lower speed) or maximum cooling (100% speed).
4. Temperature target — Some AxeOS versions let you set a target ASIC temperature. The firmware then adjusts fan speed to maintain that target. A target of 50–55 °C is a good balance between cooling and noise.

At stock settings (~48 °C ASIC temperature), the fans will run at moderate speed — quiet enough for a home office. At full speed overclocked settings (~57 °C), fans will ramp higher but stay under 40 dB.

Frequency Tuning

The NerdQAxe++ Rev 6.1 ships with a default frequency that targets 6.0 TH/s. You can adjust the core frequency in AxeOS to dial in your preferred balance of hashrate, power consumption, and heat.

Understanding Frequency and Voltage

• Core Frequency (MHz) — Controls the clock speed of all four BM1370 chips. Higher frequency = more hashes per second = more power and heat. The stock baseline is 600 MHz (4.8 TH/s). The Rev 6.1 default runs higher for ~6.0 TH/s.
• Core Voltage (mV) — Controls how much electrical potential is supplied to each ASIC core. Higher voltage provides stability at higher frequencies but increases power and heat. These two settings are interdependent — you cannot push frequency indefinitely without also raising voltage.

In the AxeOS dashboard, navigate to the Tuning / ASIC settings to adjust these values. Changes require a save and reboot.

Monitoring & Optimization

The NerdQAxe++ gives you two monitoring interfaces: the built-in T-Display screen for at-a-glance checks, and the AxeOS web dashboard for detailed metrics and configuration.

AxeOS Dashboard Metrics

• Hashrate — Displayed in TH/s. At Rev 6.1 defaults, expect 5.5–6.0 TH/s as the rolling average. Momentary spikes and dips are normal — judge performance over 15–30 minute intervals.
• ASIC Temperature — Average temperature across all four BM1370 chips. Target 45–55 °C for 24/7 operation.
• Fan Speed — Both fans’ RPM or percentage. If one reads 0, that fan may be disconnected or failed.
• Shares Accepted — Valid shares submitted to your pool. This should steadily increase. Stagnation means a pool connection issue.
• Shares Rejected — Shares the pool rejected (stale or invalid). Under 2% is normal. Higher rejection rates indicate network latency or overclock instability.
• Best Difficulty — Your highest-difficulty share ever found. This is your personal record — your closest approach to finding a block. The NerdQAxe++’s 6 TH/s produces higher-difficulty shares more frequently than single-chip devices.
• Uptime — Time since last reboot. Longer is better. Frequent reboots suggest power or thermal issues.
• Power Consumption — Estimated wattage. Useful for tracking your electricity cost (at 100W, about $7–10 per month at typical North American rates).

T-Display Screen Info

The LILYGO T-Display S3 cycles through information screens using the two programmable buttons:

• Main screen — Real-time hashrate, ASIC temperature, and WiFi status
• Pool screen — Connected pool, share count, best difficulty
• System screen — Firmware version, IP address, uptime

The display eliminates the need to open a browser for routine checks. Walk by your NerdQAxe++, glance at the screen, and confirm everything is green.

Expected Performance Targets

Overclocking Guide

The NerdQAxe++ has meaningful overclocking headroom. With four BM1370 chips and a dual-fan cooling system, you can push significantly beyond stock — but you are also pushing 100W+ power draw higher, so respect the thermal and electrical limits.

Safe Overclocking Procedure

1. Baseline first — Run at the Rev 6.1 default settings for at least 1 hour. Record hashrate, temperature, power draw, and rejection rate. This is your reference point.
2. Increase frequency by 25 MHz — In AxeOS tuning settings, bump the core frequency up one increment. Save and let the NerdQAxe++ restart.
3. Monitor for 30 minutes — Watch hashrate stability, ASIC temperature, fan speeds, and rejected shares. If stable, temperature is under 60 °C, and rejection rate is under 2%, the overclock is stable.
4. Repeat in 25 MHz steps — Continue stepping up until you observe instability: crashes, reboots, rising rejection rates, or temperatures above 65 °C.
5. If unstable, increase voltage by 10–20 mV — More voltage gives the chips electrical headroom at higher frequencies, but increases heat and power draw. Watch your PSU — if your 120W supply is at its limit, you need a bigger PSU before pushing further.
6. Back off one step — Once you find the instability threshold, drop frequency back by 25 MHz. This margin accounts for summer heat, voltage fluctuations, and long-term component aging.
7. Run a 24-hour stability test — Leave the overclock running for a full day. Check uptime, average hashrate, and that no unexpected reboots occurred. Only after 24 hours of clean operation should you consider the overclock final.

Thermal Limits

Efficiency Tradeoffs

The NerdQAxe++ achieves 16.5 J/TH at stock — extremely efficient. As you overclock, efficiency degrades because power consumption scales faster than hashrate at higher frequencies. Here is the rough curve:

• Stock (600 MHz, 4.8 TH/s) — ~100W, ~20.8 J/TH
• Rev 6.1 default (~6.0 TH/s) — ~100W, ~16.5 J/TH
• Moderate OC (~6.5 TH/s) — ~120W, ~18.5 J/TH
• Aggressive OC (~7.0+ TH/s) — ~140W+, ~20+ J/TH

For solo mining, raw hashrate matters more than efficiency — every extra hash is another lottery ticket. But if you are paying attention to electricity costs, the Rev 6.1 default is the sweet spot: maximum hashrate per watt.

Running Multiple NerdQAxe++ Units

One NerdQAxe++ at 6 TH/s is formidable. A fleet of them is how Block #920,440 was found — six units running together on the same pool and Bitcoin address.

Multi-Unit Setup

• Each unit is independent — Every NerdQAxe++ has its own WiFi connection, its own AxeOS instance, and its own pool configuration. They do not communicate with each other.
• Use the same Bitcoin address — Configure all units with the same Bitcoin wallet address. On Public Pool, your combined hashrate from all devices appears as one total under your address.
• Use worker identifiers — Append unique device names: bc1q…address.nqaxe1, bc1q…address.nqaxe2, etc. This lets you identify individual units on the pool dashboard.
• Power planning — Each unit draws ~100W. Six units draw ~600W. Plan your power delivery: use dedicated circuits, quality power strips rated for the total wattage, and adequate ventilation for the combined heat output.
• WiFi bandwidth — Stratum protocol uses minimal bandwidth (kilobytes per minute), so even 10+ units on one WiFi network is fine. The limiting factor is WiFi client count — most home routers support 20–30 simultaneous clients without issues.
• Static IPs for all — Assign a static IP to each unit in your router. Managing 6+ miners is much easier when you know exactly which IP belongs to which device.

The Math: Stacking the Odds

Six NerdQAxe++ units at 36 TH/s — approximately the setup that found Block #920,440. At ~$52/month in electricity for a shot at 3.125 BTC, the economics speak for themselves. This is not a guarantee — it is a probability game. But the probability is not zero, and Block #920,440 proved it.

Troubleshooting

For additional troubleshooting steps that apply across all AxeOS-powered devices, see our Bitaxe Troubleshooting Guide.

Most NerdQAxe++ issues have straightforward solutions. Work through these in order before contacting support.

WiFi Connection Issues

Symptoms: The NerdQAxe++ keeps broadcasting the AxeOS access point, or the T-Display shows “WiFi: Disconnected.”

1. Confirm 2.4 GHz — The ESP32-S3 does not support 5 GHz WiFi. This is the number one cause of WiFi failures. Create a dedicated 2.4 GHz SSID if your router uses band steering.
2. Verify SSID and password — Reconnect to the AxeOS hotspot (192.168.4.1) and re-enter credentials. SSIDs are case-sensitive; passwords must be exact.
3. Check for special characters — Characters like ‘ ” & # $ in your SSID or password may cause parsing issues. Try a simpler network name or password temporarily.
4. Move closer to the router — Set up within line of sight of your router first, then move to the permanent location.
5. Check router client limits — If you are running multiple miners plus other IoT devices, your router may have hit its client cap.
6. Factory reset — Use the AxeOS web interface or the reset procedure to clear saved WiFi credentials and start fresh.

Hashrate Variance

Symptoms: Hashrate fluctuates wildly or is consistently below 4.5 TH/s at Rev 6.1 defaults.

1. Wait 15–30 minutes — The hashrate display uses a rolling average that takes time to stabilize after boot. Initial readings are unreliable.
2. Check power supply — An undersized PSU (below 10A at 12V) causes voltage sag under load. The BM1370 chips cannot run at rated frequency without stable voltage. Upgrade your PSU.
3. Check ASIC temperature — If any chip is overheating, AxeOS throttles frequency to protect it. Improve airflow or reduce ambient temperature.
4. Verify all four chips are hashing — In the AxeOS dashboard, check if the system reports all four ASIC chips active. A dead chip means 25% less hashrate. If a chip is not initializing, try a firmware reset or contact D-Central support.
5. Update firmware — Newer AxeOS releases may include BM1370 optimization improvements. Check the ESP-Miner GitHub releases page.
6. Check XT30 connection — A loose XT30 connector causes intermittent power delivery issues. Disconnect and firmly re-seat the connector.

Thermal Throttling

Symptoms: Hashrate drops over time, ASIC temperature consistently above 65 °C, fans at maximum speed.

1. Check heatsink mounting — Verify the spring-mounted heatsink has even pressure on all four chips. A failed spring means one chip has no thermal contact.
2. Clean the fans — Dust buildup reduces airflow. Use compressed air to clear the fan blades and heatsink fins.
3. Improve ambient airflow — Move the unit to a more open location. Point a desk fan at the intake side for supplemental cooling.
4. Reduce overclock — Drop frequency by 25–50 MHz. This is the fastest and most effective fix for thermal issues.
5. Lower ambient temperature — Room temperature directly affects ASIC temps. A room at 20 °C gives you 5–10 °C more headroom than 28 °C.
6. Replace thermal pads — After 12+ months of continuous operation, thermal pads can dry out and lose effectiveness. Contact D-Central for replacement pads.

Display Issues

Symptoms: T-Display S3 screen is blank, frozen, or showing garbled data.

1. Check the ribbon cable — The display connects to the PCB via a ribbon cable. Ensure it is fully seated in its connector. Do not force it — these connectors have a latch mechanism.
2. Reboot the unit — Disconnect and reconnect power. The display initializes during the boot sequence.
3. Firmware update — Some display bugs are firmware-related. Update to the latest AxeOS version.
4. Display vs. mining independence — A non-functional display does NOT affect mining operation. The NerdQAxe++ will continue hashing and submitting shares even with a dead display. Use the web dashboard instead.

No Shares Submitted

Symptoms: Hashrate displays a number, fans are spinning, but share count stays at zero.

1. Verify pool settings — Double-check URL, port, and Bitcoin address. A single typo prevents shares from being accepted.
2. Check internet connectivity — The T-Display should show WiFi connected. If WiFi is connected but shares are not being submitted, your router may be blocking the Stratum port. Try changing your router DNS to 1.1.1.1 or 8.8.8.8.
3. Wait 10–15 minutes — The first share can take several minutes depending on pool difficulty settings.
4. Try a different pool — Temporarily switch to solo.ckpool.org:3333 to rule out a pool-side issue.
5. Power cycle everything — Restart the NerdQAxe++, then your router. Fresh connections resolve many intermittent issues.

Firmware Updates

For detailed firmware procedures including USB recovery, see our Bitaxe Firmware Update Guide — the process is identical for all AxeOS devices.

AxeOS receives regular updates with performance improvements, bug fixes, and new features. Keep your NerdQAxe++ firmware current for optimal performance.

1. Check your current version — The firmware version is displayed on both the T-Display screen and the AxeOS dashboard (System section).
2. Download the latest release — Visit the ESP-Miner GitHub releases page. Download the correct .bin file for your hardware.
3. Note your settings — Write down your frequency, voltage, pool URL, and Bitcoin address. Some updates reset configuration to defaults.
4. Navigate to OTA Update — In the AxeOS dashboard, go to System → OTA Update.
5. Upload the .bin file — Select the firmware file and click Update. The upload and flash takes 1–3 minutes.
6. Do NOT disconnect power during update — Interrupting the flash process can brick the ESP32-S3, requiring a USB serial connection to recover.
7. Verify after reboot — Check that your pool settings, overclock parameters, and fan configuration are intact. Reconfigure if reset.

Frequently Asked Questions

Upgrade Path

Already running NerdQAxe++ units and want even more hashrate? Here is the natural progression:

• Add more NerdQAxe++ units — The simplest upgrade. Each additional unit adds ~6 TH/s to your fleet. Six units at 36 TH/s is the proven block-finding configuration.
• NerdOctaxe Gamma — The next step up in the open-source miner family. With eight BM1370 chips, the NerdOctaxe Gamma delivers approximately 12 TH/s from a single unit — double the NerdQAxe++. Same AxeOS firmware, same WiFi-based setup, just more silicon working in parallel.
• Bitcoin Space Heaters — When you are ready for serious hashrate AND want to heat your home, D-Central’s Bitcoin Space Heaters use full-size ASIC miners (S9, S17, S19 editions) enclosed in custom housings that direct 1,000–3,000W of heat into your living space. Mining and heating in one appliance.

Block #920,440 sits on the Bitcoin blockchain forever — proof that a solo miner with open-source hardware on a desk can find a full block and claim 3.15 BTC. Your NerdQAxe++ is running the same firmware, the same chips, the same SHA-256 computations right now. Every second, it computes trillions of hashes, each one a legitimate attempt at the next block. Most will not be the one. But one of them might be.

That is the beauty of solo mining. That is the beauty of open-source hardware. That is why we build these machines, test them by hand in Laval, and ship them to miners around the world. Bitcoin’s security does not depend on warehouses in Texas and data centers in Iceland. It depends on people like you, running miners at home, keeping hashrate decentralized and the network sovereign.

Every hash counts.
