Announcement: Public Yggdrasil Peer

I'm happy to announce that Rob's Gemini Capsule now also serves as a public Yggdrasil peer. You can connect to the network at:

tcp://jsreed5.org:18000

Yggdrasil is a project to develop a network routing scheme between devices that is fully decentralized and can scale up to Internet-sized mesh networks.^ Each node in the network generates a cryptographic key that is used as its identity, and other nodes can route to it based on its identity alone. The core of the project is the routing scheme, but its primary implementation is an IPv6 overlay network in which each device's address is derived from its public key.

The fact that Yggdrasil uses an IPv6 overlay is extremely useful. It allows computers and smartphones to connect to each other over the existing Internet, but in a way that manages addresses and routes automatically. No central authority is needed to provision networks or assign IP numbers.

Yggdrasil has a large test network with thousands of concurrent peers. It can also be run entirely independently as a closed network, which is my primary use case: I use Yggdrasil to access my devices when I'm away from home or on a separate network.

I'm very interested in decentralizing digital (and physical) infrastructure as much as possible, and for a long time I've wanted to host relays for decentralized services. Yggdrasil is the first of these. I intend to add more services in the future, such as a public Syncthing relay.
