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.
