Home-Based Miner Achieves Rare Bitcoin Block Win
A home-based miner astonishingly clinched a Bitcoin block win this past weekend, achieving a staggering victory with odds estimated at roughly 149 million to one. Utilizing a consumer-friendly Canaan Avalon Nano 3S, the individual secured Bitcoin block 951771 at approximately 00:27 UTC, resulting in a reward worth around $232,000. This achievement came through Braiins Solo, a mining pool tailored for solo miners who wish to retain the complete reward upon finding a block.
Mining Rig Specifications
The successful mining rig operated at a hashing power of 6.68 terahashes per second (TH/s) while consuming only 140 watts of electricity. To put this into context, the overall hashing power of the Bitcoin network at that moment stood at about 1,000 exahashes per second (EH/s), equivalent to 1 zettahash per second (ZH/s). The Canaan Avalon Nano 3S is priced between $250 and $300, designed for home use, and serves the dual purpose of being a compact, quiet machine (operating at 33 to 40 decibels) while also functioning as a space heater in colder environments.
Odds and Rewards
The probabilities of this specific model discovering a block were calculated to be around 6.72 in a billion, translating to an approximate one in 148,904,370 chance. When accounting for the daily average of 144 blocks mined, the odds narrowed down to about one in 1.03 million for such a device, implying an extraordinary estimated waiting time of around 2,831 years for a solo win.
The entirety of the block reward equated to 3.1404 BTC, comprising a 3.125 BTC subsidy along with transaction fees approximating 0.0154 BTC, or $1,137. Given that Bitcoin’s value hovered near $73,800, the overall payout ranged from $230,000 to $232,000. The miner’s successful coinbase transaction was routed to the address bc1qdaqf9ynzwtzjtv5j8h47rfen3vwr7d85hxy8vn.
Mining Fleet and Future Prospects
Interestingly, this solo miner wasn’t just using the Canaan Avalon Nano 3S; they reportedly operated a small collection of rigs that included two Avalon Mini 3 units, along with a dozen Avalon Nano 3S units, creating a combined hashing power of about 147 TH/s. At this fleet level, the chances of winning a block improve to about one in 6.7 million, suggesting an expected return every 127 years. However, the network credited the single Nano 3S unit as the key player behind the achievement.
Significance of the Achievement
Achievements in solo mining such as this are exceedingly rare, with only around two dozen blocks found independently in the previous year. Other notable solo wins in 2025 and early 2026 included miners like a Nerdqaxe++ machine and Bitaxe miners, both achieving significant block finds.
This event highlights the resurgence of interest in solo and hybrid mining initiatives amongst hobbyists. Numerous platforms, such as Futurebit Solo, CKPool Solo, Public Pool, Braiins Solo, Parasite, and Nicehash Easymining, have emerged to support this niche. While large mining pools and commercial operations dominate the Bitcoin mining landscape, such solo victories serve as a testament to the underlying blockchain protocol, which remains indifferent to the scale of investment when it comes to mining outcomes. The incident has been widely discussed across platforms like Reddit and X, reaffirming the notion that solo mining can still hold potential, albeit as a long-shot endeavor.
