That reminds me of this little onion routering thingy i made that spiraled out of control into a semi functioning project that I got hired to work on full time
Also a dev on loki-network, we have $4.1+ million USD so far invested in relays (and potentially exits). It's layer 3 (so think more like i2p) but newer crypto and much better latency.
A good overview of the project is here: https://github.com/loki-project/loki-network/blob/master/doc...
other docs here: https://github.com/loki-project/loki-network/blob/master/doc...
