Solo Miner With a Tiny 48 Terahash Strikes Bitcoin Block, Beats the Mining Pool Titans

A solo miner hit the jackpot on Saturday morning by solving block 907283, and data shows they did it with a modest hashrate of about 48.3 terahash per second (TH/s). Not bad for what’s essentially a one-person operation punching way above its weight.

CK Pool Soloist Hits Block After 2,294 Misses Since the Last One

On Saturday, a solo miner uncovered block height 907283, and according to mining buffs, the individual did it using a modest slice of hashpower. “Another Solominer just found a block,” The X account Solomining wrote. “The lucky guy had a total Hashrate of 48.3 TH/s coming from a single worker. So it wasn’t a Bitaxe, but still definitely a very small solominer with only 1/4th of the Hashrate of a modern S21+.”

The miner was operating through CK Pool, a mining pool that offers a unique twist: participants mine solo, rather than splitting rewards like in traditional pools. CK Pool gives users a solo mining experience within a pool framework, meaning the miner keeps the entire block reward and maintains full control over the coinbase transaction—the payout itself—while still benefiting from the pool’s overall infrastructure.

The last block mined by CK Pool prior to today’s find was 2,294 blocks ago at block ​​907,283. So far, CK Pool has discovered a total of eight blocks in 2025, including today’s find. In 2024, CK Pool only discovered a total of 16 blocks. Solo miners are incredibly lucky when they strike a block because they’re competing against industrial giants like Foundry, Antpool, ViaBTC, and F2pool, which operate with a great deal more power.

With such a tiny share of the network hashrate, winning is statistically improbable—like hitting the lottery. Unlike major bitcoin mining pools that dominate with massive hardware fleets, solo miners often rely on a single machine or small setup. Since rewards aren’t shared in solo setups, finding a block means keeping the entire payout. But the odds? They’re astronomically low, making each win a standout event.
