None of the given descriptions have been too clear about what it is, though. It appears to not be a drop-in solution for communication like Briar, so why make a comparison here in the first place? Instead, it appears to be physical layer-agnostic (it doesn't care if it's run over internet or HAM-radio) infrastructure to build tools on top of. So, * Is it an end-to-end encrypted overlay network like corporate VPN/Tailscale/Hamachi? * Is it an end-to-end encrypted protocol between two or more endpoints like SSH? * Is it an end-to-end encrypted messaging protocol between two or more users like OTRv3? The entire documentation returned zero results for "Tor" or "onion" (routing), so what's the improvement over Briar+Tor?
