Solo bitcoin miner wins $330K worth of block reward after renting hash power to beat steep odds, CKpool dev says

On Thursday, a single bitcoin miner claimed 3.15 BTC, worth about $330,386, for mining block 899,826 with a solo-mining setup from CKpool. The miner earned $327,625 in subsidy rewards and some $2,761 in total transaction fees, according to data from Bitcoin explorer Mempool.“Congratulations to miner bc1qa8r4up9nchkvdnhcf9feexv2jfantrk48ef374 who recently ramped up hashrate for solving the 300th block solved at solo.ckpool.org!” Con Kolivas, the CKpool developer, said on X.BTC Hash rate calculates the total computational power miners deploy on the bitcoin network. The miner operated with a weekly hash rate of 6.11 PH/s, but increased their compute power as high as 261 PH/s to mine the bitcoin block. This suggests that the solo miner likely rented additional hash rate to better their odds of earning the block reward.“This hash rate was almost certainly a rental based on there being only one worker, though the account has been mining for a while with a much lower hashrate,” Kolivas noted.While this is the 300th block solved with CKpool and the miner likely leased extra hash rate, it’s no small feat for a solo miner to mine a bitcoin block. At Bitcoin’s total network hash rate of 796 EH/s on June 5, the lone miner had a 0.03 % chance — about 1 in 3,050 — of success.It’s also not the first time a similar case has occurred, although it's rare. In April 2024, a single miner beat 1 in 5,000 odds and earned $218,544 in block rewards. Another miner surpassed odds of 1 in 1.3 million and took home subsidies worth $260,000.Disclaimer: The Block is an independent media outlet that delivers news, research, and data.
