[tor-dev] Implications of switching to a single guard node: some conclusions

2014-03-13 Thread George Kadianakis
tl;dr: analysis seems to indicate that switching to one guard node might not be catastrophic to the performance of Tor. To improve performance some increased guard bandwidth thresholds are proposed that seem to help without completely destroying the anonymity of the network. Enjoy the therapeutic q
