Also, to everyone, it appears Myriadcoin has fallen victim to a successful timewarp attack in the past 12 hours. They have issued two hard forks to correct the problem.
It does appear someone is attempting to do something similar to DigiByte on Groestl & other algos. All appears well for the moment, but as always the more hash we can get the better.
If anyone has more details on this please feel free to share. We have been doing a lot of research the past few hours. Since our difficulty adjustment is different than Myriad we have some more protection for this. We are working on an update to fix this issue. We may have to issue an immediate hard fork in the next couple days.
