A short addition: (1) various forms of onion routing are in active research. (1.1) see for example the "big data, little data, no such data" presentation of Christian Grothoff from 2017

(2) what we are still trying to solve here, mainly, is making it harder to know the path of communication. Today, if User Lora with Node A talks to User Charly on Node B, the data goes through N nodes. The N nodes between A and B are aware of (parts of) the path, but the communication remains encrypted (in very short terms explained).
