A solo Bitcoin miner solved block 938092 after renting about 1 PH/s of hash power on demand, turning a reported spend of just 119,000 satoshis — around $75 — into a full block reward worth roughly $200,000. Mining firm Braiins confirmed the result using on-chain data.
CKPool let the miner keep the entire reward
The block was found through CKPool, a platform built for solo mining. Unlike standard mining pools that split earnings across participants, CKPool allows a miner who actually finds a block to claim the whole reward. In this case, that meant the user kept the entire payout.
That kind of result remains unusual. As Bitcoin’s total network hash rate has climbed, large pools have taken a bigger share of block production by combining the computing power of many miners. For individuals, or for users renting only modest amounts of hash power, consistent success is hard to achieve. Data cited in the report shows that over the past year only 21 solo miners found a block, collecting a combined 66 BTC.
Difficulty dropped 11% before rebounding to 144.4 trillion
The solo win came during a period of shifting mining conditions. Severe winter weather in some regions forced part of the mining fleet offline, temporarily lowering the network’s total hash rate. That led to an 11% decline in mining difficulty during one adjustment cycle. The move did not last long. Difficulty later rose by 15% to 144.4 trillion.
Bitcoin adjusts mining difficulty roughly every two weeks to keep average block times near 10 minutes. For miners operating outside major pools, meaningful openings usually appear only when the network is disrupted, such as during sudden shutdowns or broad hardware upgrades. Those windows can briefly improve the odds for solo attempts or rented hash power, but they are exceptions, not the standard pattern.
Access is easier, but large pools still dominate output
The event also highlights how accessible hash-power rental has become. A user no longer needs to build out major hardware capacity or physical infrastructure before participating in mining. Temporary rented capacity can be directed either to a pool or to a solo setup, giving smaller participants more flexibility.
Even with that lower barrier, block production is still dominated by large mining pools. A short burst of rented hash power landing a full block reward stands out because it is rare. The result shows that solo miners still have a path to claiming an entire Bitcoin block reward on their own, though the odds remain extremely slim.
