Oddbean new post about login | logout Bring back cjdns for mesh networking without ISP. I remember some years ago in Spain there was a huge community mesh with simple wifi and ethernet, because ISP sucked hard in most area at the time. Too bad it didn't last.
It is still our backbone. A number of older protocols are fully decentralized and secure in conjunction with Cjdns. https://fedoramagazine.org/decentralize-common-fedora-apps-cjdns/
Nostr web services (NWS) could also be useful as an overlay network. I've heard lots of good things about the mesh ISPs in Barcelona.
