In this guide What is hash ratehow it works, and its implications bitcoin mining Other cryptocurrencies that use Proof-of-Work (PoW) consensus mechanisms. We also explore how hashrate is measured, what causes hashrate to change, and what happens when hashrate increases or decreases.

What is Hashrate?

hash rate One of the most commonly used terms in crypto space,especially Cryptocurrency mining. This refers to the total computational power a miner uses to process transactions in a cryptocurrency network that uses her PoW verification system, such as Bitcoin (Bitcoin), Bitcoin Cash (BCHMore), Litecoin (LTC), and Ethereum (ethereum) (before upgrading Merge September 15, 2022).

Mining is a method of obtaining Bitcoins and other cryptocurrencies, Advanced computers and mining rigs It’s like an application-specific integrated circuit (ASIC) miner. We are appealing mainly to those who want to steadily acquire crypto assets without using other means. crypto exchange.

Hashrate helps investors determine health Security of cryptocurrency networks By providing a clear idea of ​​the computational effort required to solve a cryptographic puzzle to facilitate the mining process.

The more computing power used to maintain a cryptocurrency network, the more secure it is and the more transactions it can process. A higher hashrate means more security, as many miners are involved in validating transactions. Likewise, rising hashrates indicate miner optimism, which equates to additional capex in computing power.

Crypto Beginner Corner:

Closely related to hashrate is “mining difficultyThis refers to the difficulty miners face in verifying transactions, grouping them into blocks, and adding them to blocks. blockchainMining difficulty is measured on a scale from zero to infinity.

For example, Bitcoin mining difficulty is measured using an internal score that starts at 1, the easiest level, and rapidly increases or decreases based on the number of competing miners on the network. Scores are revised every 2,016 blocks, which occurs approximately every two weeks. At the time of publication (October 21st) the numbers are 35,610,794,164,372. data From Blockchain.com.

Miners usually aim to find a new block every 10 minutes. So if a miner on average is validating new blocks more often than every 10 minutes, the mining difficulty will be high. On the other hand, if a miner on average is not finding new blocks more often than every 10 minutes, then mining will be less difficult.

Overall, the more miners on the network, the higher the hashrate. This means that many participants are competing for the correct hash, and are more likely to discover it quickly. Blockchains are designed to add new blocks and release new cryptocurrencies at a steady and predictable rate. The mining difficulty is programmed to automatically correct itself to maintain that rate.

How does hashrate work?

The term hash rate ishash + rate” To understand the mechanism behind hashrate, it is important to learn about hashing. A “hash” is a fixed-length alphanumeric code that represents any length of data, word, or message. “Rate” simply means speed. Various cryptocurrency projects use hashing algorithms to create unique hash codes.

Before adding a new transaction block to the blockchain network, miners must race among themselves to guess the correct hash. During the competition, miners focus on generating sub-numerical hashes linked to the “target” hash. Every new hash is unique, and miners have to go through many hashes before validating and adding a new transaction to the chain.

Upon successful hash verification, miners are rewarded with newly minted coins. We also receive a portion of the fees linked to the transactions we add to the blockchain. This is normal for blockchain networks that use a Proof-of-Work consensus mechanism.

Importantly, PoW blockchain networks utilize a programmed method known as “halving” to reduce the total supply of digital currency and spread it over the life of mining.For example, bitcoin he halves every 4 years, but dash and litecoin Set your own conditions for halving.

As of Bitcoin’s last halving, which occurred in May 2020, Bitcoin miners were rewarded with 6.25 Bitcoins for every new block they mined.of next bitcoin halving It is set to occur after the expiration of 4 years from the previous halving, reducing the block reward to 3.125 for each new block mined.

Importance of Hashrate

hashrate allow Investor Evaluate the strength of the blockchain network, especially its security. As more miners honestly dedicate their expertise, time, and resources to discovering the next block, the hashrate will rise, making it harder for malicious agents to infiltrate and disrupt the network.

Blockchain networks become more vulnerable to attacks when one individual or group of attackers buys or rents enough mining equipment to control more than 50% of the network’s hashrate. Blockchain is a trustless platform that follows the “Longest Chain Rule” principle, so any individual or group that controls a large portion of the hashrate can disrupt the network.

In such a situation, often referred to as a 51% attack, an attacker could gain access to transactions, rearrange them, or reverse their own payments. Ultimately, it compromises the integrity of the underlying blockchain.

A lower hashrate means a lower cost to perform a 51% attack, making the network more vulnerable. If the hashrate suddenly drops, the cryptocurrency platform will stop operations such as: transaction Or it will be delisted from the exchange.

Hashrate calculation explained

As mentioned earlier in this guide, cryptocurrency miners solve cryptographic transactions called hashes, which are eventually added to the blockchain as blocks. Hashrate is measured in hashes per second (H/s). This can be done using a hashrate calculator.

For example, in the case of Bitcoin, the computational power of the Bitcoin network, including the performance of mining equipment, has improved rapidly in the past decade since the birth of the virtual currency.

This has led to the need to use more convenient units of measurement to express hashrate. Hashrate measurements are categorized as follows:

  • 1kH/s is 1,000 (1000) hashes per second.
  • 1MH/s is 1,000,000 (one million) hashes per second.
  • 1GH/s is 1,000,000,000 (1 billion) hashes per second.
  • 1TH/s is 1,000,000,000,000 (one trillion) hashes per second.
  • 1PH/s is 1,000,000,000,000,000 (1,000 trillion) hashes per second.
  • 1EH/s is 1,000,000,000,000,000,000 hashes per second.

As of October 21, 2022Bitcoin hashrate is 263,004,438.117 TH/s.

Summary of what happens when hashrate rises or falls

Hashrate increase

An increase in hashrate means:

  • More computational resources are deployed to mine new blocks.
  • more power consumption;
  • Improved security on the network.
  • Mining difficulty increases, making new blocks much harder to mine.

lower the hashrate

A decrease in hashrate can lead to:

  • Fewer miners compete to add new blocks and get rewards.
  • Your network becomes less secure and vulnerable to 51% attacks.
  • Low power consumption.
  • Mining difficulty is reduced, making it easier to mine new blocks.

hashrate and altcoins

Besides Bitcoin, other cryptocurrencies Networks that operate on PoW consensus mechanisms also require hash power to run the network. Hash rates can vary widely between cryptocurrencies. For example, one coin could have a 6,600 XT hashrate and another coin could have a 3,080 TI hashrate. Additionally, the hashrate can also be increased or decreased independently for each cryptocurrency.

As with most PoW ciphers, a higher hashrate is preferred over a lower one, as it increases overall network stability and security. However, a coin’s hashrate does not determine how quickly new blocks are completed. The frequency depends on what miners refer to as the “block time” listed in the network’s mining difficulty value.

PoW altcoins include:

  • Dogecoin (Doge);
  • Litecoin (LTC);
  • Monero (XMR);
  • Bitcoin Cash (BCH);
  • Bitcoin SV (BSV);
  • Zcash (ZEC);
  • Ravencoin (RVN).

Factors Affecting Hashrate

In general, hashrate depends on various factors such as:

Chosen mining algorithm

Mining algorithms are used to facilitate the cryptocurrency mining process. Some devices perform best in networks that use the Secure Hashing Algorithm (SHA) such as Bitcoin, Namecoin and Bitcoin Cash.

However, networks using the Scrypt algorithm such as Litecoin, Gridcoin, and Dogecoin can be significantly less efficient on the same device.

Equipment specifications

Mining equipment specifications vary by manufacturer. Those looking to invest in cryptocurrency mining may need to research the performance basics of different devices so they can choose the most optimal and cost-effective option.

Cryptocurrency popularity

Popular cryptocurrencies tend to attract miners interested in producing them. As more miners connect their computing power to the network, the hashrate of the cryptocurrency in question increases and so does the difficulty of mining it.

Overall, there are general methods that miners can use to influence hashrate. For example, the temperature of mining equipment, such as a graphics processing unit (GPU), can increase or decrease hashrate. Cooler cards are often preferred.

Additionally, all mining software programs are created differently and some have improved hashing algorithms. This can affect the overall hashrate during the mining process, which can increase or decrease significantly.

final thoughts

Hashrate is a key concept in blockchain and cryptocurrency mining. Cryptominers need to understand and observe the hashrate of the cryptocurrency they are trying to mine.

Additionally, hashrate serves as a valuable resource that determines how cryptocurrency networks adjust mining difficulty. The higher the hashrate, the more stable and secure the network.
