What is Cableguard VPN: Yes, it is a VPN tunnel, that is boring. There are hundreds of companies that offer VPN services. Cableguard is a VPN Service but it is also a technology prototype for a new, and I dare say revolutionary technology for authentication.

How does it work? I modified the Noise protocol and configuration management of an implementation of Wireguard called Boringtun. Boringtun is a Rust implementation of Wireguard with a BSD license created by Cloudflare and I believe used in their product WARP. Cableguard works by managing in an unique way host identity, configuration and authentication.

Cableguard hosts have a minimalist cryptographic wallet, so minimalist that is just a file. The file holds a private key that gives Cableguard TUN access to an blockchain account, and in the account we find a very special non-fungible token, so special that can hardly be called a non-fungible token.
