A solo Bitcoin miner hit a rare win on Saturday by solving block 907283. This small-scale operator used just 48.3 terahash per second to pull it off. That’s a tiny slice of the Bitcoin network’s total power. Still, it was enough to beat the odds and walk away with the full block reward.
The miner operated through CK Pool, which is a service designed for solo mining. Unlike pools where all members share the reward, CK Pool enables every participant to retain the entire reward if they discover a block. By that, it means that the miner did not just win the 6.25 BTC block reward but also took in the transaction fees that came with that block.
Bitcoin solo mining victory after 2,294 blocks
This wasn’t the first time that a winner was produced by CK Pool, but the wait was long. This successful block was produced after 2,294 blocks. This, therefore, marks a significant moment for advocates of solo mining. This also goes to show that even small-scale systems are capable of competing despite the increasing dominance of industrial-scale mining operations.
Major mining pools such as Foundry, Antpool, and F2Pool will typically win the majority of blocks. These titans operate thousands of machines and control a vast portion of the network’s hashrate. To compare, a solo miner will usually operate with a single machine. Finding a block in this environment resembles hitting a jackpot. Chances are small, but the reward is enormous.
CK pool helps miners find more blocks this year
In 2025 so far, CK Pool has assisted miners in finding eight blocks. Last year it placed at only 16. This year’s rate might not set records, but it indicates that solo mining is alive, even though that’s uncommon. Anytime a solo miner finds a block, it’s sending a message. Power doesn’t always triumph. Luck and determination win at times.
With minimal hashrate and no large team, a single individual was able to outrank the remainder of the network, at least for one block. With more miners coming to big pools in hopes of stable returns, tales like this bring to mind the early Bitcoin days.
At that time, people mined coins with laptops and home installations. They might be going out of style, but they are not yet extinct. This weekend’s surprise indicates that the underdog still has a chance.
