there is probably bug in the qt wallet, it shows wrong balance. In the text client everything is ok. I am little bit worried about zerocoin protocol. zCoins not maturing, maybe we should wait for POS activation..
I have set up explorer based on iquidus code. It has been set on cheap VPS and therefore it will be hold for eternity. It is not finished yet. Currently masternode tab doesn't show anything, i will check this in my free time. However it's almost fully functional.
