How do you prevent Sybil attacks@p{--} somebody creating a gazillion n-client and/or hatching nodes, and voting themselves lots and lots of new currency? @p{par}

And how does a node choose a "random" node@p{--} does every node know about every other node?  If yes, then how do you avoid getting O(N^2) communication as the number of nodes (N) rises and every existing node must be told about every new node? @p{brk}
