A huge amount of hash power will mine the coin then stop all at once. The difficulty gets stuck high. It also happened to boolberry. This problem is probably in MRO and all the other cryptonote coins.
Someone should figure out how to do re-targeting better. Improve the coin instead of a straight up copy and paste job.
It looks to me like the last block took 11 minutes to find.
sorry, but that statement is wrong, my friend. duck is flying high and network is much more scalable that other cryptonote forks - look at source code. window decreased, as well as cut decreased. 11 minute blocks is absolutely normal, since block finding is a lottery and
MacOS version - there will be new build next week.
Address verification - check the length.
we are not forum guys, but we will provide some explanations and advices here.
Block time is 4 mins. I didn't notice that. Everything is working fine.
