Solo Bitcoin Miner Makes Over $200K in Rare Outcome

A solo Bitcoin miner has earned over $200,000 after successfully solving block 943411. The miner operated with a hash rate of about 230 terahashes per second and used the ckpool solo mining service to claim the full reward.

The milestone was later confirmed by ckpool’s developer, Dr. -ck, known online as @ckpooldev. He shared server logs showing the exact moment the system detected a valid solution and confirmed the block acceptance.

Solo Miner Makes Over $200K

Logs captured at 22:02:41 UTC on April 2 recorded a potential solve with a difficulty value exceeding 3.7 quadrillion. Blockchain data shows the block size reached 2.09 MB with a weight of 3.98 million weight units. It included 3,961 transactions and was attributed to “Solo CK” based on publicly available mempool records.

Following the successful validation of the block, the miner received a block subsidy of 3.125 BTC after the most recent halving event. Transaction fees added 0.014 BTC, bringing the total reward to 3.139 BTC, valued at about $210,109 at the time.

Given the scale of the achievement, Dr. -ck noted that a miner with this level of computing power faces about a 1 in 28,000 chance of solving a block daily. This highlights the statistical difficulty of solo mining compared to large mining farms that control significant portions of the network’s total hash rate.

Even so, solo mining allows participants to keep the entire reward rather than share it in a pool. This creates a high-risk model where long periods without success can be offset by rare but significant payouts.

Solo Mining Continues to Produce Outlier Results

It is worth noting that this was not an isolated event. It marked the 312th solo block solved on ckpool.

A similar case was recorded in February, when an anonymous solo miner validated a full Bitcoin block after renting a small amount of computing power for a short period. The outcome delivered the entire block reward, turning a modest upfront cost into a significant windfall.

According to CoinTab, the result came from confirming block 938,092 on the Bitcoin network. The block rewarded the miner with 3.128 BTC. The reward combined the standard subsidy with transaction fees and was valued at about $197,546 at the time.
