What Is a Hash Rate and How Does It Relate to Network Difficulty?
Hash rate is the total combined computational power being used to mine and process transactions on a Proof-of-Work blockchain. It is measured in hashes per second.
Network difficulty is automatically adjusted to keep the block discovery time constant, typically 10 minutes for Bitcoin. When the hash rate increases, the network difficulty rises to maintain the target block time, making it harder for any single miner to find the next block.
