Re: hostile node anonymity attack scenario

[Paul Forgey <paulf@xxxxxxxxxxxxx>]

Your point being the strength of the anonymity depends on the number of 
nodes. If there were, say, 2000 nodes, then one would have to create 
almost 8 billion connections. It is encouraging to know the level of 
effectiveness increases geometrically with the number of new nodes 
introduced.
