From the start, Bitcoin has been a revolutionary currency that offered new financial possibilities. As technology improved and more people began to use cryptocurrencies like Bitcoin, so did the number of miners needed for the network’s security.

The “solo miner solves block” is a type of mining that does not require the use of a pool. The second tiny miner to solve a block was on December 28, 2017.


Two fortunate miners from the Solo CK mining pool overcame all odds and contributed a new block to the Bitcoin network in the same week, which is an incredible turn of events.

A little miner with a low hash rate capability of 126 terahashes per second (TH/s) managed to solve a block on Monday. Hass McCook, a member of the Bitcoin Mining Council and a specialist in bitcoin mining, estimated the likelihood of this occurring at 1 in 1,400,000 at the time.

However, a miner from the same pool was able to solve a block with a capacity of only 116 terahashes per second (TH/s), which is even less than the first miner, according to a tweet by Solo admin Con Kolivas on January 13. Depending on the tools used, that’s probably simply one to three mining rigs.

Kolivas said, “Presumably in reaction to the other fortunate block solver, the new miner joined the pool less than two days ago.”

In that period, they “have been astronomically lucky in solving a block alone,” he added.

This is an extremely unique occurrence and amazing luck at work.

Even calling it “insane luck” would be an understatement. According to McCook, who spoke to Cointelegraph, the probabilities of this occurring are so remote that it is difficult for him to even estimate them analytically.

He said that given the little miner’s chances of success, two victories occurring only a few days apart would need odds of at least one in a billion.

To say this is highly unusual is an understatement, McCook stated after the first miner successfully solved a block.

Each miner, who may have only been using one or two computers, will get 6.25 Bitcoin (BTC) ($266,000) as compensation for their labor.
