There was a denial of service attack on the supernodes sometime within the last 48 hours. It caused supernode 4 and 5 to desync and broadcast old blocks, causing clients to desync. I've updated them and blocked the DOS ips so all should be good now. I suspect that this caused several million coins to stop staking.
Wow. So we are getting people scared. Good.
Best thing to do is to continue staking your coins. The top wallets are not moving. We are north-bound
