A small independent bitcoin miner has achieved a remarkable success, securing a block reward of 3.139 BTC with a relatively modest computational power. The miner, running at approximately 230 terahashes per second, successfully validated block 943,411 and earned roughly $210,000 from the process. Against the backdrop of the bitcoin network’s overall capacity, which is approaching one zetahash per second, this level of computing power is considered barely a blip.
Solo mining and CKpool’s significance
The fortunate miner operated through solo.ckpool.org, a pool established in 2014 that offers miners the opportunity to claim the entire block reward with just a 2% fee deduction. Con Kolivas, the developer behind CKpool, shared news of the successful block validation on social media. Kolivas explained that the chances of a miner with this level of hashrate discovering a block on any given day stood at around 1 in 28,000.
The computational resources employed by the miner can be achieved with a handful of ASIC devices—small enough for a home setup. This outcome underscores that the windfall did not come from the vast resources of a data center or a cloud-based mining operation but from a modest, perhaps even personal, configuration.
For context, large publicly traded mining firms such as Riot Platforms boast hashrates exceeding 30 exahashes per second. That figure is about 130,000 times greater than the processing power used by the solo miner who validated the recent block.
Rare solo wins and block reward history
This recent achievement marks the 312th solo block validation recorded on CKpool since its inception. Notably, there had been a 33-day streak without a solo block on the pool since the last occurrence in late February.
Over the past twelve months, miners using solo pools have collectively validated only 20 bitcoin blocks, resulting in a distribution of 62.96 BTC in rewards. On average, a solo block is discovered roughly every 19 days within these pools, although the longest gap without a block reward extended to 58 days during the year.
Despite their rarity, such individual successes have made periodic headlines recently. In December, a miner running at about 270 terahashes per second managed to find a block—despite the long odds—and secured a reward approaching $285,000. Even more striking was an incident in November, when a miner equipped with only a 6-terahash, older-model ASIC device validated a block against staggering 180-million-to-one odds, earning a reward of around $265,000.
Another notable event occurred at the end of February: a device temporarily rented with a processing power of 1 petahash and pointed to CKpool, managed to secure a block reward of nearly $200,000 after incurring just about $75 in expenses for several hours of operation.
Con Kolivas noted that such solo miner successes are mathematically possible within the framework of bitcoin’s reward structure, even if rare. He emphasized that these achievements serve as a testament to the continued possibility of home miners prevailing—however infrequently—amid the dominance of large-scale operations.
