Join a SOLO Group
Less reward per block – far better odds of finding one.
Just add #groupname to your worker name. Every miner sharing that tag hunts for a block together; if the group solves one, the same coinbase transaction pays each member proportionally – still directly on-chain and non-custodial.

Worker format
bc1qyourwallet.bitaxe01#plebsYour usual payout address, your worker name – and #groupname at the end. That is all it takes, the group is created automatically.
Public groups
Public groups show up in the list below. Other miners can use the same tag, join in and improve the shared odds of finding a block.
Hidden groups
If the tag ends in .hidden – for example #family.hidden – the group stays out of the public list. It works exactly the same and remains visible through each member’s address stats.

Frequently asked questions
What happens when I find a block?
The block’s coinbase transaction pays the entire block reward (subsidy + fees) directly to the Bitcoin address your miner is logged in with. The pool holds nothing and cannot hold anything. Freshly mined coins are spendable after Bitcoin’s usual maturity period of 100 blocks.
What is the pool fee?
0 % for classic 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.
How often does someone find a block?
Every hash is an independent chance at the full block. How often that works out on average depends on your hashrate relative to network difficulty – both numbers are live on this page so you can do the math yourself. A hit can come tomorrow or take a long while; in a SOLO Group hits are more frequent, but shared.
Which miners are supported?
Every SHA-256 miner speaking Stratum V1 or V2: Bitaxe, Nerdaxe, NerdQaxe, NerdOctaxe, Avalon Nano, Antminer, Whatsminer and more. Matching open-source hardware is available in our shop – or you can rent hashrate.
How exactly do SOLO Groups work?
You append a #tag to your worker name, for example bc1q….bitaxe01#plebs. 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.
Which port should I use?
Bitaxe, Nerd*axe and other small open-source miners use port 3333. Industrial ASICs (Antminer, Whatsminer, Avalon) and rented hashrate connect through the high-difficulty port 4334 – at their hashrate the standard difficulty would be far too low. The setup assistant picks the right port for you. Stratum V2 runs on port 3336, large ASICs use 4336.
Does the pool support Stratum V2?
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 hashrate; the protocol is binary and leaner than V1. AxeOS 2.14.0 and later and NerdQ firmware 1.0.37 and later support it: protocol SV2, host pool.opensourceminers.de, port 3336, authority public key 9awpfZGWfrRBH8fkf82mWvnXMSTC7i9M3mshB8M56cw9UXTGdYi, channel extended. Username, worker name and SOLO Groups work as with V1; the setup assistant shows the ready-made SV2 URL.
