Yggdrasil is an experimental compact routing scheme that is fully decentralised

About Yggdrasil is an experimental compact routing scheme that is fully decentralised and only requires a small amount of state to work. It is predominanently a shortest-path scheme, whereby the network will attempt to find the most direct path to the destination. Nodes are equal participants and connect to each other using peering connections which carry network traffic. Peerings can be set up over any IP network — whether that’s a direct wired or wireless link, a local area network or even the Internet. In some cases, peerings can also be set up automatically by nearby devices on the same network using multicast discovery. All nodes on an Yggdrasil network are routers and will automatically pass traffic to help it get closer to its destination where possible. This means that, even in a network that is only sparsely connected, all nodes will be reachable by all other nodes on that network. It doesn’t even matter if a node is behind a NAT — once a peering is established, traffic flo ... Read full article.
