I'm curious how they mitigate Sybil attacks. There doesn't seem to be any elaboration on that point, and any claim to a technique by which to mitigate the problem with no centralization is a very strong claim and needs some type of citation.
- woojoo666 4y agoI imagine sybil attacks are prevented at scale. The issue with Tor is that afaik it's still small enough that a nation state can buy enough relays / exit nodes to make network correlation feasible. If there were financial incentive to spin up relays, it could be way harder for any one group to control a significant portion. For some numbers, there are currently around 7000 Tor relays [1]. I couldn't find a conclusive source for the number of bitcoin miners but one source says 300,000 [2] and another says 13,000 [3]...
