Frequently asked questions

The Bitaxe Pool is the solo mining pool by Bitaxe.de, built on ckpool with servers in Frankfurt. Every miner works with its own Bitcoin address; if it finds a block, the coinbase transaction pays the entire reward directly to that address. 0 % fee, no account, no custody.

The block’s coinbase transaction pays the entire block reward (subsidy plus fees) directly to the Bitcoin address your miner is connected with. The pool holds nothing and cannot hold anything. Freshly mined coins are spendable after Bitcoin’s usual maturity period of 100 blocks.

0 % for solo mining – the full block reward goes to your address. In a SOLO Group there is a 1 % fee, which covers running the shared payout.

Every hash is an independent chance at the full block. The average waiting time follows from your hashrate relative to network difficulty – both numbers are live at the top of this page, and the mining calculator works it out for your device. A hit can come tomorrow or take years; in a SOLO Group hits are more frequent, but shared.

Every SHA-256 miner speaking Stratum V1 or V2: Bitaxe (Ultra, Supra, Gamma, Touch), Nerdaxe, NerdQaxe, NerdOctaxe, Avalon Nano, Antminer, Whatsminer and more. Matching open-source hardware with support is available at Bitaxe.de.

No. Your Bitcoin address is your username, the password can be anything. There is no account, no e-mail and no payout threshold – the reward lands directly in your wallet.

You append a #tag to your worker name, for example bc1q….bitaxe01#friends. All miners using that tag automatically form a group – no registration. If the group finds a block, the coinbase transaction contains one output per member, proportional to submitted work, plus a 1 % pool fee. Up to 50 wallets per group. Ending the tag in .hidden keeps a group out of the public list.

Bitaxe, Nerdaxe, NerdQaxe and other small open-source miners use port 3333. Industrial ASICs (Antminer, Whatsminer, Avalon) connect through the high-difficulty port 4334 – at their hashrate the standard difficulty would be far too low. The assistant picks the right port for you. Stratum V2 runs on port 3336, large ASICs use 4336.

In AxeOS under Settings: Stratum URL stratum.bitaxe.de, Stratum Port 3333, Stratum User your Bitcoin address plus an optional .workername, password x. Save, restart – after a few minutes your miner shows up in the stats above. The full first-time setup is covered in the Bitaxe setup guide.

The AxeOS home screen shows the pool status and accepted shares; one or two minutes after starting, the counter should rise. On this page, enter your Bitcoin address in the search box to see hashrate, workers, shares and best difficulty of your miner.

Yes. Next to Stratum V1 the pool speaks Stratum V2 on port 3336 (large ASICs: 4336). The connection is encrypted end to end and the pool authenticates itself with its authority key – nobody in between can read along or redirect your hashrate; the protocol is binary and leaner than V1, too. AxeOS 2.14.0 and later and NerdQ firmware 1.0.37 and later support it: in the pool settings pick protocol SV2, host stratum.bitaxe.de, port 3336, authority public key 9awpfZGWfrRBH8fkf82mWvnXMSTC7i9M3mshB8M56cw9UXTGdYi, channel extended. Username, worker name and SOLO Groups work exactly as with V1. If you stay on V1 nothing changes – both ports run side by side.

Both are real solo mining with 0 % fee. Your own node on Umbrel makes you fully independent but needs hardware, storage and maintenance. The Bitaxe Pool works immediately, keeps block templates fresh, offers stats per address and SOLO Groups – and in both cases the payout goes straight to your address through the coinbase. The node guide on bitaxe.de shows how to run your own node.
