Solo Bitcoin Miner Achieves Rare $360,000 Block Win
A solo Bitcoin miner has achieved a remarkable feat by independently solving block 910440, earning 3.137 BTC valued at over $362,000. According to CoinDesk, the miner operated with a computational power of approximately 9 petahashes per second, which statistically provided only a 1 in 800 chance per day to find a block. The mining was conducted via CKpool, a platform that allows individuals to contribute hash power without formally joining a mining pool.
The block contained over 4,100 transactions and marks only the 305th solo block solved since CKpool's inception in August 2014, highlighting the rarity of such events in today’s industrialized mining landscape. CKpool administrator Con Kolivas emphasized the exceptional nature of this occurrence, given the dominance of large-scale operators with exahash capacities in the U.S., Kazakhstan, and China.

Solo mining differs from pool mining in that there are no fees and the miner retains the entire reward. However, the increasing network difficulty of Bitcoin, driven by record-high global hash rates, means that even powerful devices can go weeks or months without success. In contrast, pool mining offers more predictable payouts, though rewards are diluted among thousands of participants.
At the time of the win, Bitcoin was trading near $115,000, reflecting a 3% decline over the previous 24 hours as traders weighed macroeconomic signals ahead of the Federal Reserve’s September meeting.
| Block Number | Reward (BTC) | Reward (USD) | Miner Hashrate | Chance per Day | Bitcoin Price |
|---|---|---|---|---|---|
| 910440 | 3.137 | $362,000 | 9 PH/s | 1 in 800 | $115,000 |
Summary: A solo miner using CKpool solved a rare Bitcoin block, earning over $362,000 with only a 1 in 800 daily chance, underscoring the unpredictable yet rewarding nature of solo mining in a landscape dominated by large-scale operations. (Source: CoinDesk)
Bitcoin’s Security After 2140: The Post-Mining Era
By the year 2140, all 21 million Bitcoins will have been mined, and the primary income for miners—block subsidies—will disappear. According to BeInCrypto, the security of the Bitcoin network will then rely entirely on transaction fees. Experts from OKX Singapore, JuCoin, and XBO suggest that the community has ample time to prepare for this transition, expecting that institutional demand and retail activity will justify premium transaction fees to maintain network security.
For over a century, block subsidies have incentivized miners to validate transactions and secure the network. Once the subsidy ends, the key question will be whether transaction fee demand can fill the gap. Gracie Lin, CEO of OKX Singapore, stated that if Bitcoin’s demand continues to grow at its current pace, it could organically create a robust fee market to sustain security.
Sammi Li, co-founder and CEO of JuCoin, believes that by 2140, Bitcoin’s role as digital infrastructure will be so entrenched in global finance that high-value settlements will naturally generate significant fees. Large institutional transactions, such as those by Harvard’s $50B+ endowment and Michigan’s pension fund, are already contributing to a healthy fee market.
- By 2040, 99% of all BTC will be mined.
- After 2140, miners’ income will depend solely on transaction fees.
- Institutional adoption is increasing, with Bitcoin representing only ~0.2% of global assets.
Layer 2 solutions like the Lightning Network are expected to play a crucial role in scaling Bitcoin, processing small, frequent transactions off-chain and reducing congestion and fees on the main network. Lior Aizik, COO at XBO, emphasized that Layer 2s will make Bitcoin usable for both micro and macro transactions, while also driving more valuable activity back to the main chain.
However, there are risks. If transaction fees do not grow sufficiently, the financial incentive for miners could decrease, potentially leading to a drop in network hash rate and increased centralization. Lin warned that the security budget could erode, possibly causing 20–30% of mining power to go offline, as seen in previous hash rate shocks.
- Risk of reduced miner incentives if fees are insufficient.
- Potential for increased centralization if small miners cannot compete.
- Existential threat to Bitcoin’s role as a reliable store of value if network security falters.
“If transaction fees are not enough to support smaller, independent miners, the Bitcoin network could become more centralized—undermining one of its core principles,” said Aizik to BeInCrypto.
Despite these concerns, industry leaders remain optimistic. The gradual timeline allows for market adaptation, and the community’s proactive approach is seen as a sign of resilience. Li concluded that if Bitcoin remains valuable in 2140, the economy will adjust to protect that value.
Summary: After 2140, Bitcoin’s security will depend entirely on transaction fees. While institutional adoption and Layer 2 solutions are expected to support a robust fee market, risks of reduced miner incentives and centralization remain. The community has over a century to adapt to this new paradigm. (Source: BeInCrypto)
