Three hops are enough for normal Tor circuits because in a three-hop
circuit, although the second hop knows some information about the
client (one of its guard nodes) and the third hop knows the
destination, no single hop has useful information about both. When a
client's choice of exit node leaks useful information about its
intended destination, as it does when using an ‘exit enclave’ and would
when using an exit node that exits to a small number of destinations.
