Sovereign Stack V2

Your own Bitcoin infrastructure starts with the question of whose copy of the blockchain counts for you. The Sovereign Stack V2 answers it with the LiquidBox V5 – Intel N150, 16 GB DDR5-4800, 2 TB NVMe SSD, Umbrel OS – and puts a Nerdaxe Gamma alongside it, computing around 1.3 TH/s at roughly 15 W with its BM1370 ASIC. The node verifies, the miner hashes.

The most visible difference to the V1 sits on the front of the miner: a 1.9-inch TFT (LILYGO T-Display S3) instead of a 0.91-inch OLED. Hash rate, shares and temperature can be read in passing without opening a browser. Power draw is unchanged: around 10 W for the node, around 15 W for the miner, so roughly 25 W together or 18 kWh a month – about €5 of electricity a month at €0.28/kWh.

Solo mining here means: your Nerdaxe submits the same candidates as an industrial farm, just less often. Every hash is a ticket, and if one lands, the full 3.125 BTC block reward plus fees end up on your own address – confirmed by your own node. The ticket costs about €3 of electricity a month, and in between the miner contributes hash rate to the network. None of it can be planned – how the lottery works is explained in our solo mining guide, and you can run the numbers in the mining calculator.

• Everything in view without logging in: the 1.9-inch TFT shows the live figures on the device. You need the browser for settings, not for the daily glance.
• One node for everything: wallet connection, Umbrel apps and the miner all hang off the same LiquidBox V5 – no second infrastructure on the side.
• No fiddling with power: 19V/65W for the node, 5V/6A for the miner – both power supplies and the cables are included.
• Open firmware on both sides: Umbrel OS and AxeOS are operated in the browser.

Both sets contain the same node. Only the miner differs – and it differs in form factor and readout, not in performance: BM1370 ASIC, around 1.3 TH/s, roughly 15 W and about 15 J/TH apply to both.

• Readout: a 1.9-inch TFT on the Nerdaxe Gamma, a 0.91-inch OLED on the Bitaxe Gamma in the Sovereign Stack V1.
• Noise: the Bitaxe Gamma is quoted under 15 dB(A); for the Nerdaxe the fan is audible and adjustable through the fan curve.
• The rest is identical: same ASIC, same AxeOS firmware, same PWM fan, same 5V/6A power supply, 2.4 GHz Wi-Fi.

To start you need a network port, two sockets and a browser. The interfaces are reachable after a few minutes; the full verification of the blockchain keeps running in the background afterwards. The miner steps are in the Nerdaxe Gamma setup guide.

For people who want to see their setup: the miner sits visibly on a shelf showing its figures while the node works quietly beside it. For homelab users who bundle wallet, apps and mining in one place. And for everyone who prefers the Nerdaxe form factor with the larger display.

The set is less suitable if every decibel matters to you – then the Bitaxe Gamma in the Sovereign Stack V1 is the variant with a documented noise figure. And if you only want to verify rather than mine, the node alone is enough.

The set contains node, miner, both power supplies, cables and a guide. Beyond that you need a free LAN port, two sockets, a 2.4 GHz Wi-Fi network for the miner and your own Bitcoin address.

The node is designed for continuous operation and is best placed where it stays connected permanently. The miner needs free air – inside a closed cabinet it gets louder than necessary.

The node is the part that stays; the mining side can grow later.

• Nerdaxe miners if a second device should join the same node.
• Mining accessories for mounts, quieter fans and power supplies.
• LiquidBox V5 on its own, if you want to run a second node at another location.

The V2 is the right choice when you build node and hash rate in one go and want to watch your miner while doing it – no cloud contract, no third-party servers, open software throughout.
