Solo Bitcoin miner defies odds to mine valid BTC block, gets $150K block reward

A solo Bitcoin miner has managed to solve/mine the 780,112th block in the Bitcoin blockchain and received a 6.5 Bitcoin (BTC) block reward in return. The estimated value of the payout is over $150,000.

The solo miner was also lucky to have produced a valid hash just after two days of the mining, as the event itself is rare and can take months for a solo miner to produce a valid hash.

The rare event occurred on March 10 and was only the 270th solo mined block in Bitcoin’s 13-year-long history. The event's rarity could be understood from the fact that a solo miner of this size will usually solve a block on average about once every 10 months.

Congratulations to miner39nDQ9BexEBXpRdkHY1z95CaMDEwh6muPW who solved the 270th solo block at https://t.co/UWgBvLkDqc with 6.7PH but doesn't appear to have been mining for very long https://t.co/WGVBC3QajX

The miner created a solo mining pool using the Solo CK Pool mining service, for which they produced a valid block hash and were rewarded with 6.25 BTC and a fee reward of roughly 0.63 BTC.

Dr Con Kolivas, the admin of the Solo CK mining pool with a Twitter username @ckpooldev noted that the miner behind the rare event might have temporarily rented hashpower to produce output hash.

Bitcoin mining requires miners to input computational power to solve and add the next Bitcoin block to the network. However, with the growing popularity of BTC mining and the constant rise in the network hashrate and powerful mining machines, it's near impossible for a solo miner to solve the whole block on their own.

Thus, a valid block hash is often produced using the computational power of multiple mining rigs, all trying to mine the next block. The block reward is distributed according to the input hashrate of each miner of mining pools.

The Solo CK mining pool has been behind several solo-mined Bitcoin blocks in the past as well. Two of these solo-mined blocks came in January 2022, only two weeks apart with the first occurring on Jan. 11, 2022, at a block height of 718,124 followed by another rare occurrence on Jan 24, at a block height of 720,175.
