I'm at a loss here....
EDIT:
OK...re-downloaded blockchain and still getting the error. Anyone know what's the deal with this?
Basically you get interest for staking your coins up to mine a block. 2% every 10 days. Since this is the 10th day from the coins launch this is likely why you are seeing the POS and checkpoint notification. We will probably get a client update soon enough which will fix the checkpoint error.
So then...should I just ignore the error and continue mining? Apologies for my ignorance here, but I've never experienced this issue before with any coin client.
yup, all will be good for now.
