A solo bitcoin miner with computing power of only 126 terahashes per second (TH / s) bypassed large mining pools by being the first to find the right solution for adding a block. For the successful inclusion of block 718 124 into the blockchain, the lucky miner received a reward of 6.25 BTC worth about $ 260,000 at the current exchange rate.
The share of the miner in the total computing power of bitcoin was only 0.000073%. The network hash rate now exceeds 170 exahashes per second (EH / s), and 1 EH / s includes a million TH / s. Accordingly, the probability of a successful block addition with this amount of computing power is only 1 in 1.36 million.
The computing power of serious mining pools is measured by several EH / s. For example, AntPool and Poolin control 26.3 EH / s and 22.19 EH / s, respectively. It is unknown how long the miner was connected to the network. Statistically, if he connected today, with the current hash and difficulty, it would take him over 9,500 days to win the race to find the right solution.
As noted by The Block, the miner is a member of the solo pool managed by ckpool and must give the platform 2% (0.125 BTC or $ 5,200). He also received a reward in the form of commissions paid by users, which in the specified block amounted to about 0.1 BTC.
Solo mining pools allow miners to add blocks on their own, providing additional services, such as connecting to the blockchain. Thanks to this, the miner takes the entire reward minus the commission, instead of proportionally sharing it with other participants in the pool.
“This is a once-in-a-lifetime opportunity,” said a ckpool administrator. – Nevertheless, the last time a miner with such a small capacity was able to solve a block in my pool was only a year ago. Usually the blocks are solved by larger miners, as it should be statistically, but there is no reason why even the smallest miner cannot do it. “
