no more backtrack on x11 now?
Good job dev

Let's hope so. Once all the other pools update their clients and we get more miners to get the difficulties of X11 and Blake higher, there shouldn't be any block jumps.
These jumps occur because the coin is not able to choose the best chain since there are still quite a lot of people are mining on the old chain.
Hopefully in some hours, it will all be sorted out.
