Recently, SparkPool released a new version, added the feature that display stale shares. Some miners are asking what is stale share, we think it is necessary to explain it in detail.
Under the current POW mechanism, the mining pools push calculation task to the miner continuously. If the mining pool receives the share of the last task submitted by the miner after a new task is sent, this share is a stale share. Of course, there is no need to worry too much about it. Stale shares will be calculated as income, but it will be slightly lower than the normal share.
The delay is mainly affected by the miner's network status, and a good network performance will greatly reduce the chance of stale shares. We hope that the miners improve their own networks, and the SparkPool will be continuously optimized the servers simultaneously.
