A home miner found block 951771 with a Canaan Avalon Nano 3S at 6.68 TH/s, beating odds of 1 in 149 million.
A home miner found Bitcoin block 951771 on May 30, 2026 at 4:27:23 PM Eastern Time, collecting a reward of 3.1404 BTC worth approximately $232,000. The machine used is a Canaan Avalon Nano 3S, a consumer device costing between $250 and $300. The block was found through Braiins Solo, a pool designed for individual miners who want to keep the entire reward when a block is found.
The machine was operating at 6.68 terahashes per second (TH/s) with a power consumption of just 140 watts. At the time of the find, Bitcoin’s total network hashrate stood at around 1,000 exahashes per second (EH/s). The probability of that single machine finding a block was approximately 6.72 in a billion, or 1 in 148,904,370. With 144 blocks mined per day, the daily odds for that device were roughly 1 in 1.03 million, with an expected waiting time estimated at around 2,831 years of continuous operation.
The total reward of 3.1404 BTC consists of the standard subsidy of 3.125 BTC plus approximately 0.0154 BTC in transaction fees, equivalent to about $1,137. With Bitcoin’s price at around $73,800 at the time of payment, the total value came in between $230,000 and $232,000.
The miner was actually running a small farm consisting of two Avalon Mini 3 units and 12 Avalon Nano 3S units, for a combined total of approximately 147 TH/s. At the fleet level, the odds of finding a block improve to roughly 1 in 6.7 million per block, with an estimated wait of one block every 127 years. However, the pool data and the block announcement attributed the discovery to a single Nano 3S worker operating at 6.68 TH/s.
The event is not isolated, but remains rare. Over the past 12 months, approximately 20 similar events have occurred. In April 2026, a Nerdqaxe++ device at 4.8 TH/s found a block worth around $224,000. Previously, miners such as Bitaxe and Futurebit Apollo had also found blocks independently. Services supporting individual mining include Futurebit Solo, CKPool Solo, Public Pool, Braiins Solo, Parasite, and Nicehash Easymining.
