Hash Rate is a familiar term in the cryptocurrency world, especially with Bitcoin. It represents the computing power of the entire network and plays an important role in securing and maintaining the operation of the blockchain.
To better understand hashrate and its role, follow the AZcoin article below.
What is hashrate?
Hashrate is a term used in the blockchain and cryptocurrency field to measure the computational power of a blockchain network.
A higher hashrate indicates a stronger and more secure blockchain network, as the difficulty of these hash computations in the mining process also increases accordingly
How does hashrate work?
Hashrate measures the computational capability of a blockchain network by counting the number of hash computations (hashes) the network can perform within a unit of time, typically one second. Here's the basic process:
⚙ Hash Function: Each blockchain uses a specific hash function to transform input data into a fixed-length random hash string.
⚙ Mining process: In Proof of Work (PoW) blockchains, miners attempt to solve a complex mathematical problem through trial and error (brute force), computing millions or even billions of hashes per second to find a valid hash value.
⚙ Difficulty adjustment: The difficulty of the mathematical problem adjusts based on the total computational power of the network. The goal is to maintain an average time interval of around ten minutes between new blocks being added to the blockchain (block time) or to ensure the consistency and security of transactions.
⚙ Network security: A higher hashrate makes a blockchain network more resistant to 51% attacks, where an entity controls more than half of the network's hashrate and could potentially manipulate transactions and other network activities.
The unit of Bitcoin's hashrate
Hashrate is measured in "hashes per second" (H/s) or larger units to assess computational volume. Additionally, some commonly used units for Bitcoin's hashrate include:
🔰 Kilohash (KH/s): Equivalent to 1,000 hashes per second.
🔰 Megahash (MH/s): Equivalent to 1 million hashes per second.
🔰 Gigahash (GH/s): Equivalent to 1 billion hashes per second.
🔰 Terahash (TH/s): Equivalent to 1 trillion hashes per second.
🔰 Petahash (PH/s): Equivalent to 1 quadrillion hashes per second.
🔰 Exahash (EH/s): Equivalent to 1 quintillion hashes per second.

Where to track Bitcoin hashrate?
Currently, there are several websites that provide information about Bitcoin's hashrate. Some well-known and reliable websites such as Blockchain.info, CoinDesk, and BitInfoCharts all offer maps and charts that allow users to track changes in hashrate over time.
Additionally, these websites also enable users to monitor the hashrate of other cryptocurrencies such as Ethereum or Litecoin. This helps users gain a broader overview of the cryptocurrency market activity.
Relationship between hashrate and Bitcoin price
Hashrate and the price of Bitcoin have a significant correlation. A higher hashrate, meaning more computers mining Bitcoin on the network, tends to make Bitcoin more attractive to investors. This is due to two main reasons:
➰ Enhanced security: With a higher hashrate, the Bitcoin network becomes more secure, reducing the likelihood of attacks. This increases investor confidence in Bitcoin as a secure investment, thereby driving up its price.
➰ Increased scarcity: A higher hashrate also means that mining Bitcoin becomes more difficult, leading to a reduction in Bitcoin supply. This scarcity tends to push the price higher.
However, the relationship between hashrate and Bitcoin price is not always straightforward. Sometimes, the price of Bitcoin can increase significantly while hashrate remains stable or vice versa. This variability is influenced by other factors such as public interest, investment strategies, and overall cryptocurrency market fluctuations.
Future of hashrate
With continuous technological advancements, it can be predicted that hashrate will continue to increase in the future. This implies that mining Bitcoin will become more challenging, requiring miners to invest more to sustain their operations.
Additionally, we may witness the emergence of new hashrate units or new technologies applied to Bitcoin mining. However, it’s crucial to ensure a balance between technological development and the security of the Bitcoin network.
