There was some issues with the publisher mining yesterday when we were pushing out the update for the ad exchange. It should be back to normal now? Apologies for this we try to cause minimum disruption to the network when doing updates but it’s still something we can improve on.
I can’t think what would have caused this. We didn’t change the mining algorithm at all on this update. Could be a knock on effect but 3-4 times less is a huge difference and nothing should have changed the distribution of tokens that much. Publisher rewards are still going out at the same fixed daily distribution. I know that on the Wednesday we pushed out the update mining rewards were down for everyone because of disruption to the network but it should have gone back to normal the following day.
