User gen erated public keys serve as identities and all business logic is executed client side to minimize reliance on 3rd party infrastructure. Thanks to so cial media clients\, users have started to create lists of public keys tha t they want to receive content from\, thus creating the first web of trust that bootstrapped successfully. However\, I just use nostr as an overlay network\, which allows me to ignore low level networking details when I wa nt to implement application layer tooling for mesh networks.
