The Yggdrasil Network is an opportunistic mesh that can be deployed privately or as part of a global-scale network. Each node gets a stable IPv6 address (or even an entire /64) that is derived from its public key and is bound to that node as long as the node wants it (of course, it can generate a new keypair anytime) and is valid wherever the node joins the mesh. All traffic is end-to-end encrypted.
Yggdrasil will automatically discover peers on a LAN via broadcast beacons, and requires zero configuration to peer in such a way. It can also run as an overlay network atop the public Internet. Public peers serve as places to join the global network, and since it’s a mesh, if one device on your LAN joins the global network, the others will automatically have visibility on it also, thanks to the mesh routing.
It neatly solves numerous problems of portability (my ssh sessions stay live as I move networks, for instance), VPN (incoming ports aren’t required since local nodes can connect to a public peer via an outbound connection), security, and so forth.https://bit.ly/3zJ4xNY
