What Is Bitcoin Hashrate? Meaning, Uses & Why It Matters

If you have been reading about mining in Bitcoin, you have probably heard the term ‘hashrate’. However, it is thrown around without proper explanation in price analysis, news about mining, and network security. For newcomers, this can be confusing since the values related to hashrate are often in thousands of exahashes per second and are impossible to interpret on their own.

In this guide, we will define Bitcoin hashrate, explain how it is measured, learn the reasons behind its fluctuations and what they mean. Additionally, we will understand why you need to care about hashrate if you are holding or trading Bitcoin and don’t mine a single coin yourself.

Key Takeaways

• Hashrate is the collective amount of computing power used by miners to find new blocks and process transactions in Bitcoin.
• It is measured in hashes per second, and the current level of hashrate of the Bitcoin network is in hundreds of exahashes per second (EH/s), sometimes reaching zettahash (ZH/s).
• Higher hashrate indicates a more secure network, because it is more costly and difficult to get an advantage over other participants and influence the block production process.
• The value of hashrate depends on the price of BTC, cost of electricity, efficiency of mining hardware, and changes in mining regulations.
• The difficulty adjustment mechanism ensures that blocks continue appearing every ten minutes irrespective of how hashrate changes.
• Hashrate is a security and network-health indicator, it is not a price predictor and needs to be analyzed together with other metrics.

What Is Bitcoin Hashrate?

Bitcoin hashrate is the combined computational power of all miners who use SHA-256 algorithm for Bitcoin. Every ten minutes or so, miners compete with each other to find a new block in the blockchain and receive a block reward and transaction fees.

A “hash” is nothing more than the output of a one-way function. Input some data, in this particular case, a candidate block of transactions together with some other fields, and you get a deterministic output that appears to be an arbitrary combination of letters and digits of a specific length. It is impossible to reverse-engineer any input from the hash. The only way to find a suitable hash meeting the difficulty target of the network is by using brute force and trying billions upon billions of combinations of possible inputs.

Hashrate is simply the number of such operations that can be done per second. This is a pure measure of computation speed and has absolutely nothing to do with estimation of any values or prices. When we say that Bitcoin hashrate is, for example, 900 exahashes per second, we mean that the total network of miners is able to compute about 900 quintillion hashes per second.

How Is Bitcoin Hashrate Calculated?

As there is no central authority tracking each miner and their equipment, it is impossible to calculate hashrate directly. What we can do is to estimate it based on two known parameters: current mining difficulty and average actual time needed to mine a block. Blocks mined faster than in ten minutes indicate that more computational power has been added to the network; slower – that the hashrate dropped.

Hashrate units have changed a lot since Bitcoin launched in 2009. At first, the computational power of a desktop CPU was several megahashes per second (MH/s). With time, as the mining hardware got updated, first with graphics cards (GPUs) and then with special application-specific integrated circuits (ASICs), the relevant units changed from GH/s, TH/s to PH/s and now to EH/s (a billion billion hashes per second).

In 2025, the network saw the hashrate reach the mark of 1 ZH/s or 1,000 EH/s, but then retreated slightly due to changes in mining economics. The hashrate of the network is estimated using different rolling averages , such as 3-day, 7-day, and 30-day simple moving averages . This is done in order to make sure that the data is less volatile since, on the contrary, the numbers may be heavily influenced by an especially high or low sequence of blocks.

Why Hashrate Matters for Network Security

Hashrate is usually considered the most critical security metric for Bitcoin, and there is a very clear explanation for that. The Proof of Work consensus algorithm works on the basis of the “majority rules” principle, meaning that only the chain, which represents the greatest amount of computations, will be considered as the true record of transactions. 

Thus, in order to perform either rewriting or, more generally speaking, a 51% attack on the network, the bad actor would have to control more than half of the network’s computing power for long enough time in order to outdo all the other miners.

As the current size of the network is concerned, this would be quite a big challenge. In fact, one would have to acquire enough specialized ASICs as well as enough electrical power supply. In addition to that, the attempt itself is likely to become noticeable long before it turns into reality. From a practical point of view, the larger hashrate means more costly and difficult attacks.

That is another reason why the abrupt and drastic changes in hashrate get the analysts’ attention. Low hashrate does not indicate any problems with network security due to automatic difficulty adjustment in Bitcoin. However, the number of nodes participating in the mining process gets lower, so there are fewer parties contributing to the formation of the blocks, which can be regarded as being weak compared to having a lot of miners.

What Miners Actually Do

There are two basic functions performed by miners that are connected to each other. Firstly, miners collect the pending transactions in order to form a block. Secondly, the miners have to find such a hash of the block that is less than a predetermined target based on the current difficulty. That is why the task of the miners is just guessing one because the miners should try various inputs of a block to find a hash that satisfies the required conditions.

Only one miner who finds such a hash first receives the reward. He adds his block into the blockchain and receives the block reward of 3.125 BTC for each block mined since the last halving and the fees for the transactions from the users of the network. Other miners who have been trying to guess the hash and did not manage to do so do not get any rewards for the block but keep working with the next one.

Because of the extremely low possibility to win the block reward, most of the miners join mining pools where lots of miners participate in the process. The reward is distributed between the participants according to the size of their contributions.

Why the Difficulty Adjustment Matters

The protocol of bitcoin is set in such a way that the system tries to mine a block after approximately ten minutes regardless of the computing power put into the network. The system achieves this through the process of adjusting the difficulty of the blocks every 2,016 blocks, which is approximately two weeks.

When there is a rise in hashrate from the previous period of difficulty adjustment implying that blocks were mined faster than the ten-minute target, the difficulty rises to balance this out. In case there is a fall in hashrate during the previous period of difficulty adjustment implying that blocks were mined at a lower pace compared to the target rate, the difficulty falls so as to make the mining process easier. This is among the reasons why production of Bitcoin blocks has remained stable over the past years despite the rise in mining firms.

Why Bitcoin’s Hashrate Fluctuates

Hashrate is neither a constant nor always increasing. It changes depending on various economic and environmental factors, which include:

Price of Bitcoin.

The price of Bitcoin affects hashrate because it determines whether mining is profitable or not in terms of electricity cost. Rise in the price of BTC makes mining more profitable, and more mining equipment is attracted. This increases the hashrate while fall in price makes mining non-profitable hence making the hashrate fall.

Electricity cost.

Mining is a process that uses lots of energy. The profitability of mining is therefore determined by electricity cost paid by the miner. Location of cheap electricity attracts mining firms and vice versa.

Hardware efficiency.

The newer generations of ASIC miners calculate more hashes per each unit of electricity spent on running them. As the more efficient hardware is coming out and the older one gets replaced, the correlation between hashrate and energy expenditure becomes less obvious.

Regulation.

The regulations set up by a government could greatly impact the network’s hashrate. One of the examples of that is a very well-known case when a huge part of hashrate had been banned and moved somewhere else because of the regulation in that region.

Seasonal influence.

In some areas where mining operations take place, hashrate decreases in summer as the result of increased energy consumption for cooling purposes and increases in winter.

None of those factors on their own is a surprise. That is precisely what the difficulty adjustment is for – to smooth out the fluctuations.

Bitcoin Hashrate in 2026: Recent Trends

Throughout the life of the Bitcoin network, its hashrate has been increasing. Starting with the few megahashes in 2009, the network managed to break through the barrier of several hundred exahashes in 2026 and reach the level of one zettahash in 2025 for the first time ever.

From that moment onwards, along with the fall in the price of Bitcoin, the hashrate has decreased as well. Due to the decrease of Bitcoin’s price from over $80,000 to under $60,000, some mines operating at a higher price point have become unprofitable and shut down. It is quite a common scenario in the mining industry, which is known as a miner capitulation.

However, it should be noted that data about hashrate provided by various sources may vary slightly since each source applies its calculation formula and period. It would be reasonable to focus more on weekly and even monthly hashrate dynamics than on daily ones.

Hashrate vs. Difficulty vs. Hashprice: Clearing Up the Confusion

These three metrics are related to each other but remain different. Here are the reasons why people may get confused with these notions:

• Hashrate is the measure of the computing power applied for mining and expressed in hashes per second.

• Difficulty is the value of the target of block generation adjusted by the protocol in order to keep average block generation rate at approximately ten minutes in relation to the changing hashrate.

• Hashprice is the measure of revenue received per hash produced by the miners and expressed in dollars per petahash per day. In other words, it is the measure of revenue from mining, depending on the block reward and market value of Bitcoin per each unit of computational power.

In terms of hashrate and difficulty, one may estimate the level of security and competition in the network, while in terms of hashrate, one may understand the economic situation of those people, whose equipment helps to ensure the functioning of the network. Thus, a network may possess very high hashrate and low hashprice at the same time, which means that the competition in the network is rather high in comparison with the revenue per unit of work performed. Such a trend occurred several times in 2026.

What Hashrate Means for Crypto Investors

There is no need in having mining hardware for using hashrate as a significant metric in the analysis of the ecosystem situation. All people owning Bitcoins and trading them can consider hashrate to be a useful and somewhat informative indicator:

• Network security. The higher hashrate, the more secured the network is in terms of performing attacks.

• Miners’ commitment. Professional miners spend millions on creating and maintaining the mining facility; thus, it proves that Bitcoin will hold its value.

• Increasing participation trend. It is typical for the hashrate increasing to correlate with increasing participation and infrastructure development.

Still, there is a necessity to underline that hashrate cannot be used as the indicator for pricing. There are plenty of reasons that influence Bitcoin prices; thus, the process of the formation of Bitcoin price is rather complex and consists of many other factors than calculating the hashrate. However, hashrate may be used as only one factor while making the analysis of the network state.

Traders who are interested in tracking the price of Bitcoin along with some information about the network may visit the Bitcoin Price Page on the website of BTCC. There you will find the information regarding the current Bitcoin price and its performance, as well as general information about the market. As BTCC provides for trading Bitcoin, you do not have to use mining hardware.

How Hashrate Affects Mining Profitability

For a miner, hashrate means that it is good for the network but bad for the miner. Increased hashrate means that the network is becoming stronger and safer. However, at the same time, more and more competition appears as the reward per each block remains the same. As more miners join the network, the probability to find the next block becomes lower.

It means that inefficient and small mining operations have to go to the mining pools, which provides much greater opportunity to earn something than competing with more powerful companies. Besides, with the development of hashrate, mining with more energy-inefficient devices becomes less profitable, meaning that people have to change their equipment.

Forecasting future trends for Bitcoin hashrate

Compared to the start of its operation, Bitcoin has seen a significant increase in its hashrate, corresponding to increased investments in mining capacity around the world. Such periods when the hashrate of the network drops, such as in 2026, should be considered a part of natural process in the industry when profitability is associated with the cost of Bitcoin and electricity, not the weakness of the network.

In the future, some trends will affect the hashrate, such as improvement in the efficiency of ASIC chips, relocalization of mining to cheap electricity or eco-friendly regions and efforts to respond to criticisms related to energy consumption of the industry. They do not change the place of hashrate in terms of indicators of computing power of the network.

Common Misconceptions About Hashrate

Here are some of the common misconceptions about Bitcoin hashrate that should be discussed.

“Higher hashrate means the Bitcoin price will go up.” This is probably one of the most common myths about Bitcoin hashrate. The degree of the truthfulness of the statement is hard to tell, given the historical experience of the crypto asset. Nevertheless, there is a certain connection between the variables in question. However, the fact is that the hashrate depends on the price and not vice versa. There were cases when the rise in the hashrate coincided with the falling of the price. Such things happen because of the usage of mining equipment regardless of the decline in the profitability.

A falling hashrate means the network has been compromised.” Actually, there are several reasons why the reduction in the hashrate takes place, including the economic ones like the fall in BTC price, the growth in electricity prices and outdated ASICs. In this case, the difficulty adjustment is specifically made to ensure the stability of the system at such moments.

“One must constantly monitor hashrate as an individual miner.” This is completely unnecessary for an amateur solo miner, as now almost all mining is conducted through pools and special mining hardware ASIC that cannot be beaten using only home computers. Also, regular users will be more benefited from studying the concept of hashrate than monitoring its dynamics.

Where to Track Bitcoin Hashrate Data

There are some data providers that estimate the current hashrate and show the difficulty charts and mining profitability calculations. When comparing the figures from different providers, it is important to pay attention to the averaging period that a particular provider uses, as, for example, 3-day averaging period will seem to be more volatile than 30-day one, even though.  

By monitoring the trend of the hashrate via several sources of information, rather than only relying on a single one, one can easily determine whether the hashrate changes steadily or sometimes drops because of the fluctuations in block time.

Conclusion

Bitcoin hashrate might appear somewhat confusing to many people, especially because of its huge value, however, the essence of the hashrate is quite simple: the hashrate is the total computing power of all global miners involved in protecting the network and transaction validation.

Distributed computing power of the network shows how resistant the network is and how much has been invested into mining. This indicator fluctuates from time to time and this process depends on many factors, such as the price of cryptocurrency, electricity costs, technological improvement and regulation. However, this is quite normal, as the network adapts to the difficulty level.

FAQs

What is the hashrate of Bitcoin?

What is the good Bitcoin hashrate?

There is no specific criterion. It depends on the development of the industry, and bigger numbers are usually considered more safe.

How do you calculate the Bitcoin hashrate?

This metric cannot be calculated directly. There are some calculations based on the current difficulty and average time to find blocks.  

Why does the Bitcoin hashrate increase or decrease?

This metric changes due to the price of BTC, electricity cost, efficiency of hardware used and mining regulations. The high profitability increases the hashrate and vice versa.

What is the difference between hashrate and mining difficulty?

Hashrate is a total power of all the machines working in the Bitcoin network. Mining difficulty is an adjustable number, which is aimed to maintain block generation time around ten minutes.
