> "SimpleX has no identifiers" only means "SimpleX does not add additional identifiers"
These two statements are identical. IP addresses are Internet user identifiers, not SimpleX identifiers. All other application-level networks have identifiers of their own, in addition to IP addresses.
The goal of the design is:
- to prevent correlation of which IP address communicates with which,
- to prevent IP address from servers not chosen by the users.
It is not supposed to protect IP addresses from all servers, and Tor does not achieve that either, as Tor relays are servers too.
