A solo Bitcoin miner pulled off a rare feat this week, solving a block and pocketing a reward worth roughly $200,000. The miner's hashrate peaked at 100 PH/s, but the developer of the mining pool CKPool said the computing power was likely rented — and described it as 'wildly variable.'
The solo miner's big hit
Finding a block alone is a long shot. Most blocks are snagged by large mining pools that combine hashrate from thousands of participants. This solo miner beat those odds, at least for one block. The reward — 3.125 BTC plus fees — came to about $200,000 at current prices.
Why the hashrate mattered
CKPool's developer noted that the miner's hashrate peaked at 100 PH/s but was 'wildly variable.' That pattern suggests the miner didn't own a steady fleet of rigs. Instead, the developer said, the hashrate was likely rented — a short burst of power from a service that lets users buy computing time. Rented hashrate can spike and drop fast, which matches the variable profile CKPool saw.
What CKPool saw
The pool's software tracks each participant's contribution. For this miner, the numbers jumped around far more than a typical home setup would produce. The developer's public comment didn't name the miner or the rental service, but the observation lines up with a growing trend: solo miners occasionally rent hashrate for a few hours to try their luck. It worked this time.
The block was mined earlier this week. No further details about the miner's identity or plans have emerged.
