TL;DR
- Rare Solo Win: A BTC miner with only 70TH solved block 944,306 and earned 3.128 BTC worth $222,012, overcoming extremely low odds.
- Tiny Hashpower Share: The BTC miner contributed just 0.0000069% of the network’s hashrate, far below major operators like Bitdeer and MARA Holdings.
- CKpool Advantage: CKpool’s solo setup lets the BTC miner keep the full reward, continuing a streak of recent solo wins that includes $210,000, $350,000, and $285,000 payouts.
A BTC miner working alone achieved a rare victory early Thursday after solving block 944,306 and securing the full 3.128 BTC reward. The event stood out because the operator used CKpool’s solo mining setup, which allows individuals to keep the entire payout if they successfully discover a block. According to Mempool, the reward included 3.125 BTC in subsidy worth $221,800 and 0.003 BTC in fees valued at $212, bringing the total to $222,012. The BTC miner operated with minimal hashpower, making the outcome even more remarkable given the network’s scale.
Congratulations to miner bc1q~edvj with only 70TH for solving the 313th solo block at https://t.co/AvNND5PHDY!
A miner of this size has only a 1 in ~100,000 chance of solving a block per day, or once every 300 years!https://t.co/14Q5vIFAXs pic.twitter.com/jeMnSZ7JUG— Dr -ck (@ckpooldev) April 9, 2026
Hashpower Behind the Unlikely Win
The BTC miner responsible for the block solve worked with only 70TH, a level of hashpower comparable to a single Bitmain Antminer S17+ from 2019. CKpool developer Con Kolivas highlighted the improbability of the achievement, noting that a miner of this size faces roughly a 1 in 100,000 chance of solving a block per day. That probability translates to an expected success rate of once every 300 years. Despite those odds, the BTC miner managed to secure the entire reward, demonstrating how solo mining can still produce rare but significant outcomes for determined operators.
Network Share and Industry Comparison
Mempool data shows the BTC miner contributed only about 0.0000069% of Bitcoin’s estimated 1.02 ZH/s network hashrate on April 9. In contrast, major public operators such as Bitdeer and MARA Holdings report hashrates of 71 EH/s and 61.7 EH/s. The gap illustrates how small the BTC miner’s footprint was relative to industrial-scale competitors. Even so, the solo approach allowed the BTC miner to capture the full payout instead of sharing rewards through a traditional pool structure.
How CKpool Enables Solo Success
CKpool functions differently from standard mining pools. Although technically a pool, it is primarily used by individuals who want to mine independently without running their own infrastructure. Users accept a much lower probability of finding a block, but if successful, they keep nearly the entire reward minus a small fee. This model appeals to BTC miner setups that prioritize full payout potential over consistent earnings. The BTC miner in this case benefited from that structure, turning a low-probability attempt into a substantial reward.
Recent Solo Mining Streaks
This event follows several recent solo wins. Just last week, a CKpool user earned about $210,000 for solving block 943,411 after a 33‑day drought. Kolivas noted that the miner had roughly a 1‑in‑28,000 chance of success. Other notable wins include a $350,000 block reward in September and a $285,000 reward in December, each achieved by miners facing century‑scale odds. Larger Bitcoin mining operations using managed or rented hashpower have also secured blocks in recent months, showing that solo mining continues to produce surprising results.
