Tor's got a structure that makes running fake Tor nodes not quite as trivial as it sounds. Remember that Tor node operators are not anonymous, and Tor on the other hand is a semi-centralized service.
Sigh. Apparently I have to add you to my list of people who don't read, too? Quoting from my first post on this thread:
Tor places much less emphasis on decentralisation than Bitcoin does and relies on a kind of central control by a group of "directory authorities", which can (and do) ban nodes.
You don't have to remind me how Tor works, I am well aware. The directory authorities have no real way to know if nodes are related, if the operator doesn't make silly mistakes like giving them all related names.
In any case, my personal objection isn't so much the passports for Tor idea - that's a genuinely hard problem - it's the application of that to zeroconf and fee estimation where there's much better ways to do it by not relying on trusting third parties. That's an example of lazily resorting to centralization when there's better solutions out there.
The code for fee estimation is being implemented right now, so if you have something better now would be the time to build a convincing prototype.
I started writing a response to the trolling and self-congratulatory garbage that followed after this part of your post, then thought better of it. Actions speak louder than words, don't they?
