Hash rate refers to the speed at which a computer or mining rig solves cryptographic puzzles to validate transactions on a blockchain. It is measured in hashes per second (H/s), with larger units like kilohashes (KH/s), megahashes (MH/s), gigahashes (GH/s), and terahashes (TH/s) used for higher rates.A higher hash rate means more computing power, which increases the chances of successfully mining new blocks and receiving rewards. It also contributes to the security and stability of the network, as more miners make it harder for any single entity to manipulate the blockchain.Conversely, a lower hash rate can indicate reduced mining activity or a less secure network. Investors often pay attention to hash rates when assessing the health and viability of a cryptocurrency. Ultimately, a competitive hash rate is essential for maintaining trust and integrity within the system.
