- A solo Bitcoin miner secured $350,000 using 2.3 petahashes.
- Overcame 1 in 375,300 odds to mine block 903883.
- CKpool solo win showcases small-scale mining potential.
One miner mined a complete block, earning approximately 350,000 dollars.CKpool single miner used a 2.3 petahash per second rig to mine block 903883. This achievement proves that the small-scale miners have a chance to compete in a domain dominated by colossal companies.

The miner’s success came against staggering odds. By contrast to a network hash rate of more than 846 exahashes per second, a 2.3 petahash installation is a drop in the computing ocean. Industry experts estimate the odds of success of such a game at 1 in 375,300 or approximately once every eight years for a miner of this setup.
Defying the Odds in Bitcoin Mining
The CKpool administrator praised the miner for the achievement and noted that the miner broke the block using very low hash power compared to industrial installations. It is a rare victory because there are huge mining pools that operate with thousands of petahashes. Subsidies of 3.125 BTC block reward and fees were expected to be 349,028 USD.

According to bitcoin historian Pete Rizzo, it was a show of the decentralized spirit of the network. The success brings out the nature of the design of Bitcoin, in which every individual with computational power has a low probability of mining a block.
The miner must have used the older generation ASIC gear that is capable of producing 2.3 petahashes. Even small-scale miners use this kind of setup, though the exact specifications remain unknown, it costs much less than industrial rigs. This ready availability gives hope to hobbyists who would like to venture into the mining of Bitcoin.

In April 2025, the network difficulty stood at 123.23 trillion, making solo mining even more difficult. But this follows a rerun in June 2025, when a different lone miner earned 330,000 for breaking block 899,826. Such rare wins evidence that perseverance can bring great rewards.
Solo mining is an elaborate process of solving some complex cryptographic puzzles to confirm transactions and receive the full block reward. Unlike in the instance of pool mining, where the payment is split, the solo miner keeps all the reward. This is normally compared to a lottery because the success is minimal, but the reward is enormous.
The governance of gigantic mining pools contrasts with the micro system operated by the miner. In June 2025, the industrial players cut down the level of production, and this created an opening for the smaller players. This win demonstrates the randomness of Bitcoin mining, since the combination of luck and strategy may result in an unimaginable outcome.
Such rewards are even more important due to the fact that the price of bitcoin in 2025 is above 109,000. The market trends that are driving the interest in mining are institutional investments and legislative changes. The success of the miner would give a positive message to other individuals to take up solo mining despite the odds.
