Most cable + DSL lines (here in the UK at least) can get a new IP address at

large subnets so the chances of getting the same one again subsequently are
pretty low.

How fast? Can you give me an approximate figure of # of IP addresses per day? (Sorry, I don't know what "DHCP renew" is!)


For the greedy operator to benefit substantially, he has to create new IP addresses faster than it takes to figure out that he's being greedy. So if he can get a new IP address only once a day, but it takes us as little as 20 minutes to cut him off for being greedy, then we can tolerate it, and negative trust can work.

However, Toad has claimed that *even getting new IP addresses is an easy
matter* for a greedy operator.  How many new IP addresses are we talking
about here?  If the average per day over, say, a month is very low, then
we can probably tolerate it, as he won't be able to create nodes fast
enough to give him a great edge.

So, can negative trust work?
