Just as the network's hash rate soared and mining difficulty increased, a lone 'SOLO miner' managed to win the 'once in a hundred years' jackpot with a minuscule hash rate and a 0.00278% chance of winning, successfully capturing the Bitcoin block number 913,593 amidst fierce competition, ultimately securing 3.129 bitcoins (approximately 347,000 USD) for themselves.

According to the data from the blockchain explorer Mempool, this lucky miner successfully mined a block through the independent mining platform CKpool on September 8, earning a block reward of 3.125 bitcoins (approximately 347,509 USD), plus a transaction fee of 0.004 bitcoins (471 USD), bringing the total reward to 3.129 bitcoins (approximately 347,980 USD).

In response, CKpool developer Con Kolivas also posted on social media platform X to congratulate: 'Congratulations to the miner at address bc1q~jr38, who mined the 307th independent block with only 200 TH/s of computing power!'

The probability for miners of this scale to successfully solve a block each day is only 1/36,000 (0.00278%), which means they would need to mine for an average of 100 years to wait for a chance!

What is the concept of a computing power scale of 200 TH/s? It is roughly equivalent to the computing power of a 2024 Bitmain Antminer S21 air-cooled miner.

According to Mempool data from September 8, the computing power of this independent miner accounted for only about 0.00002% of the total bitcoin network power (which was estimated to be 1.04 ZH/s at that time), so small that it can almost be ignored.

In comparison, according to public financial reports, the US-listed mining companies Marathon Digital (MARA) and Iris Energy (IREN) have computing power of 59.4 EH/s and 50 EH/s, respectively, far beyond what individual players can compare with.

Why do some people still insist on 'SOLO mining'?

In the vast bitcoin network, due to the extremely low probability of independent mining successfully winning block rewards, smaller miners typically choose to join 'mining pools' to aggregate their computing power for joint mining, and then share the rewards according to their contribution ratio, thus exchanging for stable and predictable income.

Nevertheless, there are always some miners who prefer to go solo. They take a gamble through independent mining pools, aiming for that 'winner takes all' block reward. This model avoids the fees charged by mining pools, and although the success rate is slim, winning would be akin to winning a life-changing lottery ticket.

In fact, the legend of small fry toppling big whales is not the first time it has been staged. For instance, in 2022, an independent miner with only 126 TH/s of computing power miraculously mined a block, claiming a reward worth approximately $260,000.

In recent months, several independent miners with larger-scale self-owned or leased computing power have successfully mined bitcoin blocks, continuously writing amazing chapters in the cryptocurrency world.
