A solo bitcoin miner with an estimated computing power of about 230 terahashes per second achieved the remarkable feat of validating block 943,411 on Thursday. Despite having a minuscule share of the network’s total hashrate that rounds to zero on most dashboards, they secured approximately $210,000 worth of 3.139 BTC.
This miner connected through solo.ckpool.org, an anonymous pool introduced in 2014 that allows participants to keep their full block rewards minus a 2% fee. CKpool’s developer, Con Kolivas, confirmed the win via X, highlighting that the miner faced roughly a 1-in-28,000 chance of finding a block on any given day.
Kolivas tweeted: “Congratulations to miner bc1qtt7cr9cxykyp9g4hq47zf5lq9t97cxvq72lun3 with ~230TH for solving the 312th solo block [link]. A miner of this size has a 1 in ~28k chance per day of solving a block. [link]”.
With a total network estimated at about 1 zetahash per second, the winning rig’s output constitutes approximately 0.00002% of bitcoin’s total hashrate as of early April. This level of performance suggests operation from home-scale ASICs rather than larger industrial or cloud-based mining setups.
For comparison, Riot Platforms, a listed miner, operates over 30 exahashes—about 130,000 times the winning rig’s output on Thursday.
This block marks CKpool’s 312th solo victory since its launch and comes after a 33-day period with no wins. Solo pools have found only 20 bitcoin blocks in the last year, distributing about 62.96 BTC, averaging roughly one block every 18.7 days, with the longest gap lasting 58 days.
This win continues a pattern observed throughout this cycle. In December, a miner with around 270 TH/s overcame 1-in-30,000 odds to claim approximately $284,633. In November, a miner running at just 6 TH/s, typically expecting to find a block in hundreds of years, beat 1-in-180-million odds to win roughly $265,000.
Additionally, in late February, a miner converted about $75 worth of rented cloud hashrate into a $200,000 reward by directing merely 1 petahash at CKpool for several hours.
