Two independent miners found Bitcoin blocks roughly seven hours apart on November 7 through Solo CKPool, receiving more than $230,000 each and approximately 6.276 BTC combined, or about $476,000, including transaction fees. Bitcoin developer Mononaut reported the development on X, while Mempool records confirmed that Solo CK produced both blocks. Block 974,893 paid about 3.1335 BTC, and block 974,930 paid approximately 3.1427 BTC. The combined total corrects the newer record's erroneous reference to 6,276 BTC. Solo miners retain the block reward rather than sharing it across a conventional mining pool, although Solo CKPool charges a 2% infrastructure fee. Bitcoin mining resembles a lottery because machines compete to solve a mathematical puzzle, with one miner roughly every 10 minutes earning the right to add a block. A setup with two or three powerful machines could have roughly a 1-in-40 chance of finding a block over a year under current network conditions, compared with Powerball's 1-in-292 million jackpot odds for one ticket. Hardware, electricity and the possibility of earning nothing for years or decades make solo mining financially demanding despite occasional wins by small operators.
