1. Different Ways of Hashrate Statistics

Miner Hashrate: The hashrate displayed locally on the miner refers to the actual hashrate value calculated by the miner during its operation. This usually reflects the maximum computing capacity of the mining machine, but it doesn't necessarily represent the effective hashrate ultimately received by the mining pool.

Mining Pool Hashrate: The hashrate shown by the mining pool is the effective hashrate actually received by the mining pool, that is, the number of computing tasks successfully submitted to the mining pool. The mining pool will conduct statistics based on the effective workload submitted by miners, and there may be losses caused by network delays, packet losses, or computing tasks that were not submitted in a timely manner.

2. Error Range

Generally speaking, it is normal to have an error between the hashrate of the mining machine and that shown by the mining pool, especially within a short period of time. This is because:

The hashrate of the mining machine is usually a peak value, representing the highest computing capacity of the miner when there are no network or other limiting factors.

The hashrate shown by the mining pool will be affected by factors such as network delays and packet losses, so the displayed hashrate often tends to deviate.

For common equipment:

The error of ASIC miners is usually around 2% - 3%.

The error of GPU miners is relatively larger, usually around 5%.

3. Unofficial Mining Addresses

If you are using an unofficial mining address or some unstable mining pools, the error in hashrate may be even greater, and it's even possible that the effective hashrate shown by the mining pool is zero. This is because the unofficial addresses may not correctly receive and count your effective hashrate, resulting in inaccurate data.

4. Delay in Mining Pool Data Updates

Mining pools usually update computing power data at certain time intervals. If your mining machine has just started operating, the mining pool will need some time to obtain the data and calculate the effective hashrate. Therefore, in the initial stage, the hashrate shown by the mining pool may be lower than the actual hashrate. Generally, the average hashrate over 24 hours will be more accurate than the data within a short period of time (such as 15 minutes), because the data in a short period of time may have larger errors due to greater fluctuations.
