I'm drafting a system I'm calling MONAD. It's kinda like Tor, where you select relays and route your traffic through them using 'onion routing'.
Anybody can run a relay, and the users pay the relay operators for their service. The payments are bitcoin micropayments using cashu, using our
@Cashu 'spilman channel' system for very efficient payments.
This repo is quite out of date; I hope to push my latest code in a couple of weeks when it's ready
