On April 10, an unknown miner using the Solo CK pool mined Bitcoin block #944306, earning a reward of 3.128 BTC, worth about $222,000 at the time. The data comes from mempool.space.
The miner’s hashrate is estimated at around 70 TH/s — roughly equivalent to one or two home ASIC devices. According to analysts, at that level of hashrate, the probability of mining a block in a single day is about 1 in 100,000, which statistically translates to once every 300 years.
What Is Solo CK
Solo CK is a pool designed for solo mining, where participants do not combine their computing power but instead compete against the network individually. The entire reward goes to whoever finds the block first, with no sharing involved. Most miners with this level of hashrate will never mine a single block — the math is simply against them.
The case of block #944306 is not the first of its kind on Solo CK: the pool periodically records wins by small-scale miners, but that does not change the underlying statistical odds.
