Bitcoin solo mining hardware for your home

In solo mining your device works alone and receives the whole reward if it finds a block. This page shows which devices suit it and how to set them up. Bitaxe, NerdQaxe and NerdOctaxe are available with 24h premium shipping.

In solo mining you enter your own Bitcoin address as the username at the pool. The pool builds the template for the next block with your address as the recipient. If your device finds a valid block, subsidy and fees go straight to that address, currently 3.125 BTC plus fees. If it does not, you receive nothing; there are no partial payouts as in a regular pool.

Which hardware is suitable for solo mining?

Any miner that lets you enter pool and address freely, which open firmware such as AxeOS or NerdOS always does. The devices differ mainly in hashrate, power needs and where they can stand:

  • Bitaxe Gamma 601 (around 1.3 TH/s, 15 to 18 W): one chip, AxeOS, frugal enough for round-the-clock operation on a desk.
  • NerdQaxe ++ (around 4.8 TH/s, about 80 W): four chips and a display, NerdOS, almost four times the hashrate of the Gamma, with an audible fan.
  • NerdOctaxe (up to 12 TH/s, around 200 W): eight chips, NerdOS. Belongs in a spare room; you will notice its waste heat in winter.

Twice the hashrate means twice the chance per block and roughly twice the power. Several small devices together have the same chance as one large device with the same total hashrate. What that means in euros and waiting time is worked out per device by the mining calculator; live network figures are on Bitcoin network live. All models side by side are in the miner comparison.

What matters in solo mining hardware

  • Efficiency (J/TH): in continuous operation every watt counts. The Bitaxe Gamma 601 manages around 13 J/TH, the NerdQaxe ++ and NerdOctaxe around 17.
  • Stability: a device that keeps restarting wastes hashing time. Use a matching power supply and leave enough air around the device.
  • Open firmware: in AxeOS or NerdOS you enter any solo pool yourself, without a manufacturer account.
  • Your own Bitcoin address: the address you enter receives the reward. Use one from a wallet whose keys only you hold.

How to switch to solo

In the firmware you enter the stratum address and port of the solo pool under the pool settings, and your Bitcoin address as the user; most solo pools accept any password, often just x. On pool.opensourceminers.de pure solo mining carries no fee, and a starting difficulty of 1,000 means even a single Bitaxe reports shares quickly. Endpoints, fees and starting difficulty of other solo pools are in the solo pool comparison, the steps in detail in the guide Setting up a mining pool.

With your own Bitcoin node and pool software such as public-pool you can even mine solo without a third-party pool. The basics of open hardware are covered on open-source Bitcoin miners.

Frequently asked questions

What is the difference between solo and pool mining?
In solo mining your device tries on its own to find a whole block, and you receive the full reward if it succeeds. In pool mining many miners work together and share the reward by contribution, so you get small amounts regularly. You can switch between the two in the firmware at any time.
Which device should I use for solo mining?
To start, a Bitaxe Gamma 601: low power, quiet, quick to set up. The NerdQaxe ++ (around 4.8 TH/s) and the NerdOctaxe (up to 12 TH/s) bring more hashrate per device but also need more power. Several small devices together have the same chance as one large device with the same total hashrate.
How high is the chance of finding a block solo?
Very low, because a home miner contributes only a tiny fraction of the worldwide hashrate. The mining calculator gives the exact figure for your device, using the network hashrate you enter. Solo blocks by small miners do happen, but do not plan on one.
Can I mine solo with any Bitaxe?
Yes. Every device with AxeOS or NerdOS can be switched to a solo pool; you only change the pool address, port and user.
Do I need my own node for solo mining?
No, a solo pool is enough. Your own node with your own pool software makes you independent of the pool operator, but costs storage space and some setup.
Where does the reward go if my device finds a block?
To the Bitcoin address you entered as the user at the pool, directly in the coinbase transaction of the block. The pool fee is taken out there: nothing for pure solo mining on pool.opensourceminers.de, 2 % on CKPool. The coins become spendable after 100 confirmations.
