Hash Rate Explanation: Operation Speed of Cryptocurrency Mining, Methods, and Calculation Techniques

In the world of cryptocurrency, one key metric that has been making headlines is the Bitcoin hashrate. This value, which measures the speed at which miners can guess the answer to a cryptographic puzzle, has been on a steady climb.

Real-time hashrate data for various blockchain systems can be found on platforms like Blockchain.com, Minerstat, BitInfoCharts, YCharts, NiceHash, Hashrate.no, HashrateIndex, Koinly, Swan Bitcoin, and others.

The hashrate of Bitcoin, measured by the number of hashes or "guesses" per second on the blockchain network, has grown significantly over the years. In 2021, as the value of Bitcoin surged, the hashrate reached over 150 million TH/s when the price of BTC hit $61,000 in August 2021.

Miners can optimize their hashrate by investing in the latest ASIC or GPU rigs, implementing advanced cooling solutions, participating in mining pools, algorithmic optimization, focusing on energy efficiency and sustainability, continuous learning and adaptation, and understanding the specifics of the cryptocurrency they are mining.

The increase in hashrate has made the Bitcoin network more resistant to attacks. A higher hashrate improves the efficiency of a proof-of-work cryptocurrency network, making it more difficult for malicious actors to gain control.

On Friday, January 3, 2025, the Bitcoin hashing power hit a record all-time high of over 1,000 EH/s. This significant milestone showcases the increasing interest and investment in Bitcoin mining.

However, the profitability of a hashrate depends on how well miners balance electricity costs and mining rewards. The higher the miner's machine's hashing power, the greater the chance that the miner will guess the hashing and the more likely they could receive Bitcoin rewards.

It's important to note that the term "good" hash rate is relative and depends on factors like the particular asset being mined, the hardware being used, and the difficulty level of the network. A Bitcoin hash rate measures the target hash used in mining and processing transactions in proof-of-work (PoW) blockchain networks.

Hashrate is the primary measurement in the entire mining process for Bitcoin's proof-of-work system and other cryptocurrency networks. The Bitcoin network's mining hashrate represents the total number of hash computations the miners can execute in one second or the size of the computational power of the whole blockchain.

The increase in the Bitcoin network's computational power from 2009 to present has been significant, with a dramatic surge in 2013 due to the introduction of ASIC miners. The hashing power has grown so much that by 2024, the global computational power averaged above 911 EH/s.

At the time of writing in May 2025, the Bitcoin hashrate is 870.87MH/s. Cryptocurrency mining involves guessing different values for the nonce by generating a new hash every time. The speed at which a miner's machine can make these guesses is called mining hashrate.

The network automatically adjusts the difficulty level based on the total hashrate so that blocks are mined at a fixed rate, such as every 10 minutes for the Bitcoin blockchain. Cryptocurrencies use unique hashing algorithms to generate hash codes with random alphanumerics denominated in hexadecimal notation.

Companies and individuals behind most Bitcoin mining devices currently in operation include Bitdeer Technologies Group, Google, as the largest shareholder of TeraWulf (14% stake), a US-based Bitcoin miner focusing on sustainable energy sources, and major firms like Marathon Digital Holdings, holding 50,639 BTC and owning one of North America's largest mining operations.
