The Hashrate of Bitcoin has recently reached an all-time high record, surpassing the threshold of 1,000 EH/s (exahash per second) at the beginning of 2025.
This peak reflects a phase of extraordinary vitality of the network, resulting from a growing interest of miners globally.
The growth of mining is not just a technical data point, but translates into greater security of the blockchain and significant impacts on the profits of operators. This is why these numbers are fueling the debate in the community.
What is Bitcoin’s Hashrate really and what does it indicate today?
For those approaching the topic, the Hashrate represents the total computational power used to process and validate transactions on the Bitcoin network.
The recent value exceeding 1,000 EH/s (up from the previous 943–946 EH/s recorded in 2024) clearly indicates a more resilient and decentralized network.
But what is fueling this surge?
At the center is the profit of the miners, which has grown significantly in the second half of 2024 and at the beginning of 2025.
The hashprice (daily earnings per PH/s) reached peaks above 60 USD per PH/s at certain times in 2024, despite experiencing fluctuations related to the price of Bitcoin and energy costs.
These data, confirmed by CoinWarz and The Block, indicate that many miners are investing in more efficient and powerful ASICs to improve operational margins and counter the growing competition.
The main mining pools continue to dominate a large portion of the global hashrate:
- Foundry USA: about 247 EH/s, recognized global leader (source: BTC.com, Hashrate Index, Cointelegraph, January 2025)
- Antpool: approximately 180–185 EH/s
- ViaBTC, F2Pool, MARA Pool, Spiderpool, Secpool, Luxor, Binance Pool, Braiins Pool, among other important ones
This concentration increases efficiency and speed in confirmations, but also raises concerns about the decentralization of the network.
If a few players control a significant share of computing power, the risk of concentration of power in the governance of the blockchain remains a hot topic.
The mining difficulty of Bitcoin is adjusted every 2,016 blocks (approximately every two weeks) to keep the average extraction time stable around 10 minutes per block.
In January 2025, the average extraction time is slightly below 10 minutes, around 9 minutes and 45 seconds.
The last adjustment in August 2024 recorded an increase of about +3%, with cumulative increases up to +24% since August 2024, indicating increasingly fierce competition among miners.
Hashrate and Security: Is it Really Impregnable?
A high hashrate makes the Bitcoin blockchain extremely secure against 51% attacks.
Since the computational power required to surpass the network grows exponentially with the hashrate, any manipulation attempt becomes economically discouraging. This stimulates trust, investments, and increasingly widespread adoption on a global level.

The forecasts for hashrate remain positive in the short term, driven by increasingly advanced ASIC technologies and a growing focus on energy sustainability.
However, fluctuations in the price of Bitcoin or significant increases in energy costs could change the scenario, forcing some less efficient miners to exit the market.
The increase in hashprice at various times in 2024 has led many operators, including small miners and specialized companies, to reactivate previously decommissioned hardware.
This creates intense competition for rewards and fuels a cycle of continuous technological renewal.

Efficiency and Environment: Race for Clean Energy
The efficiency in mining depends not only on hardware and software, but also on the adoption of more sustainable energy solutions.
More and more pools and data centers are using renewable sources and innovative cooling systems, driven also by the growing international regulatory pressure to reduce environmental impact.
The Bitcoin mining is at a turning point today: the all-time highs of the hashrate, the growing focus on real decentralization, and the global challenge of energy efficiency outline a scenario of great transformation.
The network is more secure and performant than ever, although the issues of environmental impact, scalability, and the distribution of power among the pools remain open. A crucial moment for those who want to stay updated and ready to follow the next records.
