A 1-in-180-million Event Occurred in Bitcoin: Here Are the Details

A rare event has occurred on the Bitcoin ($BTC) network. An extremely small-scale Solo CK miner has mined a block single-handedly, earning approximately 3,146 $BTC and approximately $265,000 in transaction fees at current prices.

According to on-chain data, the miner's computing power at the time the block was discovered was just 6 terahashes per second (TH/s). For comparison, the Bitcoin network's average hash rate in October was 855.7 exahashes per second (EH/s). This means the miner's share represents only 0.0000007% of the network, or about 1/7 billionth of the total.

CKpool founder Con Kolivas, in a statement on X, said that the probability of a miner of this size solving a block every day is one in 180 million, and that the event involves exceptional luck.

This block was the 308th solo block mined using the CKpool software, marking the first such achievement in nearly three months. Considered one of the luckiest solo mining examples in recent years, this event surpassed previous similar cases. In 2022, a miner with 126 TH/s managed to mine a block with a probability of 1 in 1.3 million on a network that was around 170 EH/s at the time.
