A solo Bitcoin miner achieved a near-impossible feat by successfully mining block #907,465 on July 28, 2025, securing a full block reward of 3.16 BTC (worth approximately $377,500 at the time). According to blockchain explorer Mempool and mining pool Solo.CKpool, the miner operated with an estimated hash rate of just 1-2.3 PH/s—a minuscule fraction of Bitcoin's global network hash rate exceeding 700 EH/s.
The miner participated via Solo.CKpool, managed by developer Con Kolivas, who likened the achievement to "winning the lottery." This reward comprised the standard 6.25 BTC block subsidy (reduced to 3.125 BTC post-halving in one report) plus accumulated transaction fees. Kolivas emphasized: "Solo mining is like playing the lottery — many will try, few will win, but the payout can be massive enough to change lives when it happens."
The event highlights Bitcoin's core decentralization ethos, as the miner overcame astronomical odds estimated at 1 in several million against institutional mining pools dominating the network. Despite the rarity—only a handful of such successes occur annually—the achievement has no material impact on Bitcoin's tokenomics, supply, or market dynamics.
