A solo Bitcoin miner has successfully earned a block reward of 3.141 BTC, valued at $347,455, on block height 920,440 on October 21, 2025. This achievement underscores the decentralized nature of the Bitcoin network, as the miner operated independently without joining a large mining pool. The reward comprised 3.125 BTC from the block subsidy and 0.016 BTC from transaction fees. The miner utilized infrastructure managed by Umbrel, a Bitcoin node provider, highlighting the potential for individual miners to compete against industrial-scale operations. The availability of affordable mining devices, such as Bitaxes priced between $155 and $600, is further promoting decentralization by providing open-source alternatives to large-scale ASIC mining.
