What Is “Hash Rate” and How Does It Affect a Miner’s Chance of a Reward?

Hash rate is the total combined computational power being used to mine and process transactions on a Proof-of-Work blockchain, measured in hashes per second. A miner's chance of winning the block reward is directly proportional to the percentage of the total network hash rate they contribute.

A higher individual hash rate means a greater probability of solving the next block and earning the reward.
