Citing from their website: "Yggdrasil is a new experimental compact routing scheme. It is designed to be a future-proof and decentralised alternative to the structured routing protocols commonly used today on the Internet, as well as an enabling technology for future large-scale mesh networks"
Yggdrasil is a completely separate network from the “normal” internet. It works as a global, encrypted mesh network where every device becomes part of a huge, interconnected system. It doesn’t rely on ISPs, central servers, or big companies to function.
Check out the official installation page here.
I host an Yggdrasil mirror of my website. If you’re on Ygg, you can reach ot using the link below:
