got that same error on every accepted block message, it shows me as connected and new blocks come up, though.

Apart from that: With roughly a million of these shiny Blacknet-Coins, how often would I expect to stake?
I also might be dumb, but is there any site where I can read about the rewards per stake and so on? Info on the blacknet.nija site is rather vague. It does not even explain how to find out ones own account//address, although i managed to get it on my own ;-)
