Higher competition challenges miners, but solo miners still find rare wins
Introduction
The Bitcoin mining network has reached a new all-time high in difficulty, climbing to 134.7 trillion on Friday. This milestone reflects the ongoing upward trend in computational requirements for securing the Bitcoin blockchain, even as hashrate levels show signs of fluctuation.

Rising Difficulty and Hashrate Trends
Mining difficulty, which measures how hard it is to validate a new block, previously peaked in August and has continued rising since then. According to data from CryptoQuant, Bitcoin’s hashrate has slipped to 967 billion hashes per second, down from the record 1 trillion hashes per second recorded on August 4.
Analysts point out that while the hashrate decline signals some miners reducing capacity, the difficulty adjustment demonstrates the network’s resilience and security strength. A higher difficulty ensures that blocks are mined approximately every 10 minutes, maintaining the protocol’s stability.
Impact on Mining Firms
The surge in difficulty adds further strain to large-scale mining companies, which already operate on thin margins due to energy costs and infrastructure investments. Market observers warn that rising operational requirements could intensify centralization risks, with dominant mining pools and corporations gaining more control over the Bitcoin network.
A blockchain researcher commented, “Mining is gradually becoming less accessible to small players, raising questions about decentralization and long-term sustainability.”
Solo Miners Still Score Rare Success
Despite the dominance of institutional miners, solo miners occasionally strike gold. In July and August, three independent miners successfully solved blocks on the Bitcoin ledger through the Solo CK pool.
- On July 3, one miner added block 903,883, earning nearly $350,000 in block rewards and transaction fees.
- On July 26, another mined block 907,283, taking home over $373,000.
- On August 17, a third solo miner validated block 910,440, netting similar rewards.
These cases highlight that while statistically rare, solo mining remains possible, offering smaller participants a chance to compete against large-scale operators.
The latest increase in Bitcoin mining difficulty to 134.7 trillion underscores both the network’s growing security and the mounting challenges for miners. While big corporations continue to dominate, the occasional success of solo miners shows that opportunities still exist in one of the world’s most competitive blockchain ecosystems.
