Hash rate is the number of hashes generated per second.
You will mostly observe the hash rate of your mining device in our statistics. However, you might also come across the “hash rate of the pool” or the “hash rate of the entire Bitcoin network”.
There is a difference between a nominal hash rate shown in the manual of your mining device and an effective hash rate shown in our system. It is important for you to understand the difference between these two.
Nominal Hash Rate
The nominal hash rate of 1 Gh/s means that your device is capable of generating 1 billion hashes per second - no matter if they match any criteria.
Effective Hash Rate
The effective hash rate is a hash rate calculated from hashes submitted by your device to our pool. Only a small portion of generated hashes by your devices get sent. They must fit certain criteria assigned by the pool (see: Shares).
Most of the time, the effective hash rate will be somewhat lower than the nominal hash rate.
Your effective hash rate depends on the luck of your mining device and the quality (stability) of your connection to the pool server. If you have experienced connection issues, then your effective hash rate will be lower than the nominal hash rate in that period of time.
Occasionally, you can be more lucky and find more valid hashes than usual. That is what gives you a slightly higher effective hash rate.
Scoring Hash Rate
Scoring hash rate is a value derived from effective hash rate used for rewards calculation. Please, see Reward System for the full explanation.
