Mycelium is an IPv6 overlay network. Each node that joins the overlay network will receive an overlay network IP in the 400::/7 range. Features: - Mycelium is locality-aware, it will look for the shortest path between nodes - All traffic between the nodes is end-2-end encrypted - Traffic can be routed over nodes of friends, locality-aware - If a physical link goes down, Mycelium will automatically reroute your traffic - The IP address is IPV6 and linked to a private key Scalability is essential to us. We tried many overlay networks before but got stuck on all of them. However, we are now working on designing a network that scales to a planetary level.
