An individual home-based miner operating a consumer-grade Canaan Avalon Nano 3S beat odds of approximately 149 million to 1 to capture Bitcoin block 951771 this weekend, earning a reward worth approximately $232,000.
Important points:
- A solo home miner using a Canaan Avalon Nano 3S at 6.68 TH/s won Bitcoin block 951771 on May 30, 2026 at 4:27:23 PM ET.
- Block reward 3.1404 $BTC was valued at approximately $232,000 and was paid via the Brainins Solo pool.
- Approximately 20-24 solo home mining wins have occurred in the past 12 months, with odds of approximately 1 in 149 million per block.
One block, one machine
This block was mined at approximately 00:27 UTC through Brains 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 consumed only 140 watts of power. For context, the Bitcoin network’s implicit hash rate at the time was around 1,000 exahashes per second (EH/s) or 1 zettahash per second (ZH/s).
The Canaan Avalon Nano 3S retails for approximately $250 to $300. It’s compact, quiet at 33-40 decibels, and connects via Wi-Fi or Ethernet. Canaan sells it for home use and also works as a space heater in cool rooms.
The mathematics behind victory
The probability that this particular machine will find a particular block is 6.72 in 1 billion, or 1 in 148,904,370. Since 144 blocks are mined per day, the daily odds of finding one such rig are approximately 1 in 1.03 million. If run continuously, the expected wait time to find a single block is approximately 2,831 years.
The total block reward was 3.1404 $BTCconsists of 3.125. $BTC Subsidy plus approx. 0.0154 $BTC or a transaction fee of $1,137. At the time, Bitcoin price was around $73,800, and the dividend was between $230,000 and $232,000. The Coinbase transaction was paid to the address bc1qdaqf9ynzwtzjtv5j8h47rfen3vwr7d85hxy8vn.
Small fleet, one winner
The miner reportedly operated a small fleet that included two Avalon Mini 3 units and 12 Avalon Nano 3S units, totaling approximately 147 TH/s.
At the fleet level, the odds improve to about 1 in 6.7 million per block, with a win expected every 127 years. However, the pool data and block announcement credited a single Nano 3S worker at 6.68 TH/s as the machine that found block 951771.
Not the first time, but still rare
Solo home mining wins on this scale are rare. I’ve found about 20 or so solo blocks in the past 12 months. In April 2026, a 4.8 TH/s Nerdqaxe++ machine won blocks worth approximately $224,000. In 2025 and early 2026, Bitaxe and Futurebit Apollo miners also independently discovered blocks.
Several solo and hybrid mining services cater to home miners and hobbyists, including Futurebit Solo, CKPool Solo, Public Pool, Brainins Solo, Parasite, and Nicehash Easymining. There is a resurgence of interest and participation in solo, or home-based, mining.
why is it important
Large mining pools and industrial operations control the majority of Bitcoin’s hashing power. A single home miner on a consumer device finding a block does not change that balance, but it shows that the protocol itself does not weigh outcomes by investment size. The win garnered widespread attention on Reddit, X, and mining forums, with enthusiasts calling it proof that solo Bitcoin mining still makes sense as a long shot.
