我能修改 Tor 网络中的跃点数量吗？

Right now the path length is hard-coded at three (except if you're accessing an onion service).

Why not longer?

我们不鼓励使用更长的路径，因为这将增加网络的负载，而（据我们所知）未增加任何安全性。

Also, using paths longer than three could harm anonymity, first because it makes denial of security attacks easier, and second because it could act as an identifier if only a small number of users have the same path length as you.

Why not shorter?

If we made two-hop paths, then a relay on either end of the circuit would know which relay it needs to attack (whether break into, collaborate with, or maybe just surveil) in order to identify the user.

Whereas with three-hop paths, a relay on one end doesn't immediately know which relay they would need to attack, increasing the cost, effort, and uncertainty of an attack.
