Hash Rate

Hash rate measures how many cryptographic calculations, or “hashes,” miners across the Bitcoin network perform every second. Each hash is a try at solving the Proof-of-Work needed to add a new block to the blockchain. Collectively, miners worldwide generate trillions of hashes each second, reflecting the vast computational resources dedicated to verifying transactions and keeping Bitcoin secure.

A higher hash rate makes the network more resilient, particularly against attacks like the 51% attack, where someone would need to control the majority of computing power to disrupt the system. As the hash rate increases, so does the cost and difficulty of any such attempt.

Hash rate grows in response to various factors, especially as rising Bitcoin prices attract more miners. Other influences include the price and availability of electricity, local regulations, and climate conditions, all of which affect mining profitability and participation.
