Bitcoin mining miracle! An independent miner mined 3.146 BTC with a computing power of 6 TH/s, and the chance of producing a block is only one in 180 million.
When the computing power of the entire network was once as high as 850 EH/s, a small miner with only 6 TH/s of computing power used "one in 7 billion" presence to defeat the chance of 1 in 180 million and dug out a Bitcoin block containing 3.146 BTC rewards on his own on November 21.

The chosen Bitcoin miner is born! According to on-chain data, a retail miner with only 6 TH/s (6 trillion hashes per second) computing power successfully mined a new block on his own when the entire network’s computing power once exceeded 850 EH/s (850 EH/s = 850,000,000 TH/s). Including transaction fees, he received a total of 3.146 BTC as a reward, with a total value of approximately 26.5 million dollars.

1.8 One in 100 million chance of winning
This incident occurred around 22:13 last night (21st). The miner was a small miner using Solo CKPool. According to the official confirmation from the on-chain data and Solo CKPool, the miner only had a computing power of 6 TH/s. If based on the highest average computing power of the entire network set by Bitcoin in October (approximately 850 EH/s), the miner's share of the entire network's computing power is only one in 7 billion; if calculated based on the daily probability of producing blocks, his chance of digging a block every day is only one in 180 million, which translates into an average of millions of years to get one.
In this regard, CKPool founder Con Kolivas also said excitedly on the 308th solo block at https://t.co/UWgBvLkDqc. A miner of this size has only a a in 180 million chance of solving a block each day! https://t.co/Jx3fTUlaIe pic.twitter.com/F5CKVrEfYt

In addition, it is understood that this is also the 308th block independently dug by retail miners since CKPool was launched in 2014. It is also the first "real retail" block record in the past three months. Compared with another lucky retail investor with 126 TH/s in 2022, which defeated the 1.3 million chance of producing a block, this time the "minimum computing power" of 6 TH/s was called "the luckiest solo mining event in recent years" by the mining circle. Many miners can't help but sigh: "This is the most romantic thing about Bitcoin - even if you only have an old S9 mining machine buzzing at home, you will always have the possibility of getting rich overnight."
What is Solo CKPool?
Solo CKPool is a special mining pool that allows miners to mine anonymously and independently. Once a block is successfully produced, the miner can receive all the rewards and only pay 2% to the mining pool.
In today's world where mining is highly concentrated and 99.99% of blocks are taken over by large mining pools, this incident is like winning the "Bitcoin Lotto", proving once again that the randomness designed by Satoshi Nakamoto still operates faithfully to this day: every hash has an equal chance.
