hyprspace / hyprspace

Libp2p is a networking library created by Protocol Labs that allows nodes to discover each other using a Distributed Hash Table. Paired with NAT hole punching this allows Hyprspace to create a direct encrypted tunnel between two nodes even if they're both behind firewalls.

Moreover! Each node doesn't even need to know the other's ip address prior to starting up the connection. This makes Hyprspace perfect for devices that frequently migrate between locations but still require a constant virtual ip address.

Wireguard is an amazing VPN written by Jason A. Donenfeld. If you haven't already, definitely go check it out! Wireguard actually inspired me to write Hyprspace. That said, although Wireguard is in a class of it's own as a great VPN, it requires at least one of your nodes to have a public IP address. In this mode, as long as one of your nodes is publicly accessible, it can be used as a cental relay to reach the other nodes in the network. However, this means that all of the traffic for your entire system is going through that one system which can slow down your network and make it fragile in the case that node goes down and you loose the whole network. So instead say that you want each node to be able to directly connect to each other as they do in Hyprspace. Unfortunately through Wireguard this would require every node to be publicly addressable which means manual port forwarding and no travelling nodes.

By contrast Hyprspace allows all of your nodes to connect directly to each other creating a strong reliable network even if they're all behind their own firewalls. No manual port forwarding required!
