Solo Home Miner Wins $232K Bitcoin Block With a $300 Machine at 149 Million-to-1 Odds

One Block, One Machine

The block was mined at approximately 00:27 UTC through Braiins Solo, a pool designed for solo miners who want to keep the full reward if they find a block. The winning machine hashed at 6.68 terahash per second (TH/s) and drew just 140 watts of power. For context, the Bitcoin network’s implied hashrate at the time was around 1,000 exahash per second (EH/s) or 1 zettahash per second (ZH/s).

The Canaan Avalon Nano 3S retails for roughly $250 to $300. It is compact, quiet at 33 to 40 decibels, and connects via Wi-Fi or Ethernet. Canaan markets it for home use, and it doubles as a space heater in cooler rooms.

The Math Behind the Win

The probability that this specific machine would find any given block works out to approximately 6.72 in a billion, or one in 148,904,370. At 144 blocks mined per day, the daily odds for one such rig were about one in 1.03 million. Running continuously, the expected wait time to find a single block would be around 2,831 years.

The block reward totaled 3.1404 BTC, made up of the 3.125 BTC subsidy plus roughly 0.0154 BTC or $1,137 in transaction fees. At a bitcoin price of approximately $73,800 at the time, the payout landed between $230,000 and $232,000. The coinbase transaction paid out to address bc1qdaqf9ynzwtzjtv5j8h47rfen3vwr7d85hxy8vn.

Small Fleet, One Winner

The miner reportedly operated a small fleet, including two Avalon Mini 3 units and 12 Avalon Nano 3S units totaling roughly 147 TH/s.

At the fleet level, the odds improve to approximately one in 6.7 million per block, with an expected win every 127 years. But pool data and the block announcement credited a single Nano 3S worker at 6.68 TH/s as the machine that found block 951771.

Not the First, Still Rare

Solo home mining wins at this scale are rare. Roughly two dozen or so solo blocks were found in the prior 12 months. In April 2026, a 4.8 TH/s Nerdqaxe++ machine won a block worth around $224,000. Earlier in 2025 and 2026, Bitaxe and Futurebit Apollo miners also found blocks independently.

Several solo and hybrid mining services cater to home miners and hobbyists, including Futurebit Solo, CKPool Solo, Public Pool, Braiins Solo, Parasite, and Nicehash Easymining. Solo, or home-based mining, has experienced a renewed wave of interest and participation.

Why It Matters

Large mining pools and industrial operations control the majority of Bitcoin’s hashpower. A single home miner on a consumer device finding a block does not shift that balance, but it demonstrates that the protocol itself does not weigh outcomes by investment size. The win drew wide attention on Reddit, X, and mining forums, with hobbyists calling it proof that solo bitcoin mining still makes sense as a long shot.
