A solo bitcoin miner running about 230 terahashes per second of computing power, validated block 943,411 on Thursday, cashing in 3,139 BTC worth around $210,000 despite controlling a share of the total network hash rate so small that it rounds to zero on most dashboards.
The miner was connected to solo.ckpool.org, the anonymous solo mining pool introduced in 2014 that lets operators keep their full block rewards minus a 2% fee. CKpool developer Con Kolivas confirmed the win on X, noting that the miner had a chance of approx. 1-in-28,000 to find a block on any given day.
At 230 terahashes, the winning rig represents about 0.00002% of bitcoin’s total estimated hash rate of about 1 zetahashes per second in early April. That output is consistent with a small stack of home-scale ASICs running under a single roof rather than a rented cloudburst or industrial operation.
For context, publicly traded miner Riot Platforms alone is running more than 30 exahashes, roughly 130,000 times the hashrate of Thursday’s winner.
The block is the 312th solo win recorded on CKpool since its inception, and the first since February 28, ending a 33-day drought. Solo pools have only found 20 bitcoin blocks over the last 12 months, distributing a combined 62.96 BTC. That’s about a solo block every 18.7 days on average, with a longest gap of 58 days.
The win continues a pattern that has repeated itself with surprising regularity throughout this cycle.
In December, a miner of around 270 TH/s cleared 1-in-30,000 daily odds to get a reward of $284,633. In November, a miner running just 6 TH/s output from a single old-generation ASIC that wouldn’t normally expect to find a block in hundreds of years of continuous mining beat 1-in-180 million odds to land around $265,000.
And in late February, a miner turned approximately $75 of rented cloud hashrate into a $200,000 reward by pointing just 1 petahash against CKpool for a few hours.
