And this gets you what? Users who have active wallets will have their bandwidth wasted for as long as you keep up the attack. Once you stop active wallets won't be rescanning that part of the chain and new users won't be scanning it either, as they skip blocks before their earliest key time using getheaders. So basically you can waste the bandwidth of active users for a while, by spamming transactions. This is not a new attack. Anyway, it's trivial to DoS the entire Bitcoin network today. It hasn't ever happened. Maybe one day it will, but the only rationale people can come up with for such an attack beyond random griefing is governments, and complexity attacks are really not their style. Much easier to just pass a law. I'm not saying DoS should be ignored, but I do feel there are limits to how far down that rabbithole it's worth going. ------------------------------------------------------------------------------ Everyone hates slow websites.
