A solo Bitcoin miner validated a full block using on-demand rented hashrate, earning a payout worth about $200,000 at the time.
Block reward and rented compute
Mining firm Braiins said the miner found Bitcoin block 938092 and collected the 3.125 BTC block subsidy.
The miner reportedly spent about 119,000 satoshis (around $75) to rent 1 petahash per second of hashpower and paid a small solo-mining fee.
Braiins said the miner used CKPool, which allows individuals to mine independently while using a pool server to broadcast work and submit solutions.
What the blockchain data shows
Mempool.space data shows block 938092 was mined around 8:04 am UTC on Tuesday.
Bitcoin’s hashrate and difficulty determine how hard it is to find a valid block, and difficulty adjusts every 2,016 blocks to keep average block times near 10 minutes.
Network hashrate can be tracked on Bitbo’s bitcoin hashrate chart.
Solo wins are still uncommon
Solo block wins remain statistically rare.
Data from solo miner tracker Bennet shows 21 solo miners found blocks over the past year, earning a combined 66 BTC worth about $4.1 million at current prices.
Bennet’s data also shows a solo block is found about every 17.2 days on average.
Difficulty rebounds after winter storms
Bitcoin mining difficulty rose to 144.4 trillion after the latest adjustment, a 15% increase.
The move reversed an earlier 11% drop tied to severe US winter storms, described as the sharpest hashrate decline since China’s 2021 mining ban.
