A miner with just 230 terahash per second validated block 943,411, pocketing 3.139 BTC worth approximately $210,000.

A solo miner with a computing power of approximately 230 terahash per second mined block 943,411 on Thursday, April 6, earning 3.139 BTC. The miner was connected to solo.ckpool.org, the anonymous solo mining service launched in 2014 that allows operators to keep the entire block reward, minus a 2% fee.

CKpool developer Con Kolivas confirmed the win on X, noting that the miner had approximately a 1 in 28,000 chance of finding a block on any given day. With 230 terahash, the winning rig represents roughly 0.00002% of Bitcoin’s estimated total network hashrate, which stood at around 1 zettahash per second at the start of April.

This result is consistent with a small cluster of home ASICs operating under a single roof, rather than an industrial cloud mining burst. The block is the 312th solo win recorded on CKpool since its inception, and the first since February 28. Over the past 12 months, solo pools have found a total of 20 Bitcoin blocks, distributing a combined 62.96 BTC, averaging roughly one solo block every 18.7 days with a maximum gap of 58 days.

The win is part of a series of unlikely successes that have repeated with surprising regularity in this cycle. In December, a miner running approximately 270 TH/s overcame odds of 1 in 30,000 to claim a reward of $284,633. In November, a miner operating with just 6 TH/s – the power of a single legacy-generation ASIC that would not normally be expected to find a block for hundreds of years of continuous mining – beat odds of 1 in 180 million to earn around $265,000. In late February, a miner turned roughly $75 worth of rented cloud hashrate into a $200,000 reward, pointing just 1 petahash at CKpool for a few hours.
