What Is a VPN Protocol?
A VPN protocol is a specification for a tunnel. Here is what the main ones actually decide, how they differ, and why the choice is a censorship question.
03
What Is REALITY?
REALITY replaces a proxy server's TLS with a real site's handshake, so a prober gets a genuine certificate. How it works, and what it does not solve.
04
What Is VLESS?
VLESS is a stateless proxy protocol that does almost nothing on purpose. It hands all encryption to the transport carrying it, which is why it looks like nothing at all.
05
What Is WireGuard?
WireGuard is a layer-3 tunnel over UDP with a deliberately tiny codebase and a fixed set of cryptographic primitives. Small, fast, auditable, and not built for censorship.
