We have updated our shares calculation system! 

Now when you’re mining ZIL we treat your rejected shares as stale. It allows us to avoid an overall pool hashrate degradation, before the update miner’s software has been transferring part of the miners to the back up pool when they received the “rejected share” error. 

After the update miners will be staying in the main pool whenever we switch to ZIL mining. So if you’ve experienced “rejected shares'' errors when mining ZIL now you should be earning more. 

Due to the nature of Zilliqa blockchain stale shares are not paid because there are no uncle blocks in ZIL network.
