A lone miner with a computing power of just 49 terahashes per second (TH/s) managed to process Bitcoin block 907283 on July 26, earning a total reward of approximately $376,000.  

According to mempool.space, those profits earned through the Solo CKpool server break down into a total of 0.029 BTC in fees (equivalent to almost $3,500) and a subsidy plus expenses of 3.154 BTC (over $372,000).

Con Kolivas, leader of Solo CKpool, explained the magnitude of the feat in which this solo miner beat all mining pools and industrial miners: 

 “A miner of this size has only a 1 in 130,000 chance of solving a block per day, or once every 370 years on average.” 

With Kolivas, software engineer and administrator of Solo CKpool. 

To roughly put this feat into perspective, the miner's 49 TH/s hashrate is half the power of a Bitmain S19 Pro ASIC, a device that delivers around 110 TH/s.  

In contrast, for example, Foundry USA, the world's largest mining pool at 221.8 EH/s (exahashes per second, a larger measure than TH), requires approximately 2 million of those S19 Pro ASICs to achieve that processing power. 

This means that, at block 907,283, a miner with a “medium” S19 ASIC had surpassed Foundry’s hypothetical 2 million, plus the additional thousands of thousands of other ASICs used in other pools.  

Thus, Bitcoin mining, although increasingly centralized and difficult due to the rise of industrial miners, still offers glimpses of the random and decentralized capabilities of the Bitcoin network. This practice still allows individual miners to participate in the network with scarce resources and, in some cases, take the entire reward.
