SOLO MINING FAQ

Yes — and it has happened many times. We track over 100 solo blocks found via CKPool Solo and Public Pool, which are the pools used by home miners with small devices.

Some miners had just 654 GH/s — roughly the hashrate of a single BitAxe device costing ~€100 — and still found a block worth over $200,000. The odds were 1 in ~1.2 billion per block, but they won.

The key insight: someone wins every 10 minutes. It could be a giant industrial farm, or it could be a small home miner who got incredibly lucky. The blockchain doesn't care how big your machine is.

BitAxe is an open-source home Bitcoin mining device. It uses a single ASIC chip (BM1368 or BM1370) and runs on about 10–15 watts — less than a light bulb.

Popular home mining devices:

• BitAxe Gamma — ~400–500 GH/s, €80–120, most popular
• BitAxe Ultra — ~400 GH/s, €80–100
• NerdQAxe+ — ~1.2 TH/s, multi-chip design, €200–350
• Mini ASICs (Avalon Nano, Bitaxe Hex) — 1–5 TH/s, €200–500

These devices are quiet enough for a home office, use minimal power, and can point directly at solo pools. EU buyers can get them at Mineshop.eu with no customs fees.

The block reward is the amount of new Bitcoin paid to the miner who finds each block. It consists of two parts:

1. Subsidy — currently 3.125 BTC (halved every 210,000 blocks, roughly every 4 years)
2. Transaction fees — varies by network activity (~0.01–0.10 BTC typically)

At today's price of $85,000, the total reward is approximately $265,625–$272,000. A new block is found approximately every 10 minutes.

The next halving will reduce the subsidy to 1.5625 BTC in ~2028.

SoloBlocks.io automatically fetches data from mempool.space every 5 minutes, checking all known solo mining pools for newly found blocks.

For each solo block we record: pool name, miner wallet address, coinbase tag, BTC reward, and network difficulty at the time.

We then query pool APIs to get the miner's real hashrate:
• CKPool Solo → solo.ckpool.org/users/{address} (official API)
• OCEAN → scraped from ocean.xyz/stats/{address}
• Public Pool → public-pool.io:40557/api/client/{address}

This lets us classify miners (home miner, small farm, industrial) and estimate their device type.

We currently track all major solo mining pools:

• ⚡ CKPool Solo — Most popular home miner pool. Free, lightweight, key-only auth via Bitcoin address.
• 🌊 OCEAN — Transparent pool with live miner stats and direct payouts.
• 💚 NiceHash EasyMining — Rented hashrate pointed at solo Bitcoin mining.
• 🏠 Public Pool (Umbrel) — Open-source pool that runs on Umbrel home nodes. Coinbase tag: "Public Pool on Umbrel".
• 🪨 RedRock Pool — Smaller solo pool.
• 🔵 Braiins Solo — From the company that makes Braiins OS firmware.
• 🔴 FutureBit Solo — For FutureBit Apollo home miners.

We update automatically every 5 minutes. If a new solo pool appears, we add it manually.

We use three methods, depending on data availability:

1. Live pool API (most accurate): For CKPool Solo and OCEAN miners, we fetch their actual 24-hour average hashrate from the pool's API every hour.

2. Block frequency formula (for repeat miners without API data):
H = N × D × 2³² / Δt
Where N = blocks found, D = average difficulty, Δt = seconds between first and last block.

3. Unknown: For single-block finds with no API data, we cannot determine hashrate. They could be a tiny home miner who got lucky or a large operation.

Each block detail page shows which method was used with a labelled source badge.

The probability depends on your hashrate vs. the total network hashrate. Formula:
P = your_hashrate / network_hashrate

At today's network hashrate (~1,016 EH/s):

• BitAxe Gamma (500 GH/s) → 1 in ~2 billion per block → expected ~38,000 years to find one
• NerdQAxe+ (1.2 TH/s) → 1 in ~847 million → expected ~16,000 years
• 10 TH/s home farm → 1 in ~102 million → expected ~1,900 years

These numbers sound impossible — yet people win regularly. Someone wins every 10 minutes. With thousands of home miners running 24/7, jackpot finds happen every few weeks.

Every block detail page on SoloBlocks.io shows the exact odds calculation for that specific find.

Step-by-step for beginners:

1. Get a home miner — BitAxe Gamma (~€100), NerdQAxe+ (~€300), or a mini ASIC. Available at Mineshop.eu for EU buyers (no customs fees).

2. Get a Bitcoin wallet address — Use any Bitcoin wallet (BlueWallet, Sparrow, Trezor). You'll need your receive address.

3. Configure your miner — Point it at a solo pool:
• CKPool Solo: stratum+tcp://solo.ckpool.org:3333, username = your BTC address
• Public Pool: stratum+tcp://public-pool.io:21496, username = your BTC address

4. Let it run — Your miner submits shares. If it finds the correct block hash, the pool broadcasts it and you receive the full reward directly to your wallet.

5. Track your chances — Come back to SoloBlocks.io to see when other home miners win. Your turn might be next.

On average, no — a BitAxe running at 500 GH/s has odds of roughly 1 in 2 billion per block. Statistically, you'd wait ~38,000 years to find one block. But Bitcoin mining has always been about luck.

The value of a home miner is:

• Lottery ticket: ~€5/month in electricity for a chance at $200,000+
• Education: Learn how Bitcoin actually works
• Heat reuse: Some miners use it to heat their home/office
• Decentralisation: Every home miner makes Bitcoin more distributed

If you expect to profit, use pool mining. If you want a fun, low-cost chance at a life-changing win while supporting Bitcoin, solo mining is for you.

We use multiple verification layers:

1. The block is on the Bitcoin blockchain — the hash proves it. Every block links back through the full chain. You can verify any block we show on mempool.space, blockstream.info, or blockchain.com.

2. Coinbase tag identification — the first transaction in every block contains a text signature. CKPool blocks say /ckpool/, Umbrel blocks say "Public Pool on Umbrel", OCEAN blocks say OCEAN.XYZ. This is written into the blockchain forever.

3. Pool API hashrate confirmation — for CKPool and OCEAN miners, we query the pool API using the miner's wallet address and get their actual hashrate. A 654 GH/s reading confirms a small device.

Everything is cross-referenced and linked directly to public block explorers. Nothing on this site can be faked — the Bitcoin blockchain is the ultimate truth.
