A solo Bitcoin (BTC) miner successfully mined a block on Saturday, collecting the 3.125 BTC block reward, valued at $372,773.
The miner, operating through the Solo CK pool, a solo mining service, successfully mined block 907283, which contained 4,038 transactions and block fees totalling $3,436.
Rising network hashrate and difficulty make it increasingly harder for solo miners to compete with large-scale, corporate mining firms.
Despite the odds against solo miners, one successfully mined a block in February 2025, followed by a miner who used just 2.3 petahashes to solve the puzzle and collect the $350,000 block subsidy earlier in July.
The improbable, and nearly impossible, victories of solo miners are a reminder that even smaller players can still successfully add blocks to the Bitcoin blockchain at a time when mining is dominated by large, publicly-traded companies.
