+Switching to a single guard node?
+---------------------------------
+
+Last October, Roger Dingledine called for research on improving
+Tor's anonymity by changing guard parameters. One of these parameters is
+the number of guard nodes used simultenously by a Tor client.
+
+Following up on the paper written by Tariq Elahi et al. [XXX],
+Roger's blog post, and recent discussions during the winter dev.
+meeting, George Kadianakis made a detailed analysis of the implications of
+switching to a single guard node [XXX]. He studied the performance
+implications of switching to a single guard, the performance
+implications of raising the minimum guard bandwidth for both clients and
+the overall network, and the change would affect the overall anonymity
+and fingerprintability of Tor users.
+
+Jumping to conclusions: “It seems that the performance implications of
+switching to 1 guard are not terrible. […] A guard bandwidth threshold
+of 2MB/s […] seems like it would considerably improve client performance
+without screwing terribly with the security or the total performance of
+the network. The fingerprinting problem will be improved in some cases, but still
+remains unsolved for many of the users […] A proper solution might
+involve guard node buckets [XXX]”.
+
+For a better understanding, be sure to look at George's work which
+includes graphs and proper explainations.
