Hash power refers to the computational power or processing power that is contributed to a cryptocurrency network for the purpose of verifying and adding new transactions to the blockchain. In simpler terms, it is the amount of computing power that miners or mining pools are able to dedicate to solving complex mathematical problems in order to validate transactions and secure the network.
The higher the hash power, the more secure and decentralized the network becomes, as it becomes increasingly difficult for a single entity to control the majority of the computing power. Hash power is usually measured in hashes per second or more commonly in terahashes (TH/s) or petahashes (PH/s).
Having a higher hash power also increases the likelihood of a miner or mining pool successfully mining a new block and earning the associated block rewards and transaction fees. This competitive nature of mining encourages miners to continuously invest in more powerful and efficient hardware to increase their hash power and stay ahead in the mining race.
