Once in 300 years! “SOLO miner” hits an independent block and brings back 3.128 bitcoins

In the era when Bitcoin mining has become an arms race among major players, a lone, “SOLO miner” unexpectedly overcame numerous difficulties and succeeded in winning the “once-in-300-years” jackpot, grabbing Bitcoin block number 944,306, and ultimately collecting the block reward and transaction fees totaling 3.128 BTC (about $222k).

According to blockchain explorer Mempool data, this lucky miner on April 9 successfully mined a block via the solo mining platform CKpool, earning 3.128 BTC (about $222,012), including a block reward of 3.125 BTC (about $221,800) and transaction fees of 0.003 BTC (about $212).

In response, CKpool developer Con Kolivas also posted a congratulatory message on the social platform X: “Congratulations to the miner at address bc1q~edvj; he mined independent block number 313 with just 70 TH/s of hash rate!” He said:

For a miner of this scale, the chance of successfully finding a block each day is only 1 in 100k—so on average, it will succeed only once every 300 years!

A hash rate of 70 TH/s is roughly equivalent to an Antminer S17+ from Bitmain, which was released in 2019 and is no longer considered mainstream.

Based on Mempool’s April 9 data, this solo miner’s hash rate accounted for only about 0.0000069% of the Bitcoin network’s total hash rate (then estimated at 1.02 ZH/s), so tiny it’s practically negligible. In other words, this miner is like someone holding a small shovel yet somehow striking a super gold mine.

By contrast, U.S.-listed mining companies Bitdeer (BTDR) and MARA Holdings (MARA) have hash rates as high as 71 EH/s and 61.7 EH/s respectively—far beyond what an individual player can compare to.
