Firstly, the miner's hashrate refers to its capability to perform hash calculations within a certain timeframe. On the other hand, the hashrate displayed by the mining pool typically represents the effective hashrate received by the pool from that miner. Different pools display hashrate for varying time intervals, such as the last 15 minutes or 12 hours, which results in an average effective hashrate over those periods. Theoretically, after an extended period of mining (e.g., 24 hours), these two values should align. Short-term discrepancies in mining pool hashrate should be regarded as reference data.
If your miner dashboard displays a hashrate within the normal range while the mining pool shows a lower hashrate, it is advisable to observe this for a longer period of time.
If you need further clarification, you can refer to the FAQ or support team of the specific mining pool you are connected to.
