In an astonishing sequence of events, two lucky miners from the CK Solo mining pool have defied all odds and added a new block to the Bitcoin blockchain in the same week. On Monday, a small-cap miner managed to crack a block with a modest hash rate capacity of 126 terahashes per second (TH/s). Bitcoin mining expert and Bitcoin Mining Board member Hass McCook said at the time that the odds of this happening were 1 in 1,400,000.
However, according to a Jan. 13 tweet from admin Solo Con Kolivas, another miner from the same pool was able to break a block with a capacity of just 116 terahash per second (TH/s) — even less than the first miner.
Kolivas added that the second miner only joined the pool less than two days ago, “probably wanting to follow in the other’s block-breaker luck.” “They were very lucky in breaking the solo block at that time,” he wrote. “This is incredible luck at work, and a very unusual event.” ‘Amazing luck’ might not even seem quite right. McCook told Cointelegraph that the chances of this happening were so slim, he wasn’t sure how to calculate it mathematically. He suggested that the miner’s chance of succeeding once was one in a million, so two successes just days apart would put the odds at least one in a billion. When the first miner broke the block, McCook said that: “To say this happens so rarely is an understatement.” Each miner, who may have been mining with just one or two machines, will take home 6.25 Bitcoin (BTC) ($266,000) for their efforts.
