There's no single "best" protocol — there's a best protocol for a given network, threat model, and device. The table below compares the five protocols MiTiVPN draws on, and each name links to a full history of how it came to exist.
| Protocol | Origin | Encryption | Speed | DPI resistance | Best for |
|---|---|---|---|---|---|
| VLESS | 2020, Project X / Xray-core community | Delegated to TLS | Very fast, especially with XTLS | Very high — looks like ordinary HTTPS | Heavily filtered networks, low-overhead stealth |
| WireGuard | 2016, Jason A. Donenfeld | Fixed modern suite (ChaCha20, Curve25519) | Fastest raw throughput | Low unless wrapped — recognizable by default | Raw speed on open or lightly filtered networks |
| OpenVPN | 2001, James Yonan | Configurable (OpenSSL / TLS) | Moderate, slower in userspace | Moderate — strong over TCP 443 | Compatibility, audited stability, older devices |
| Shadowsocks | 2012, independent developer "clowwindy" | Built-in AEAD ciphers | Fast, minimal overhead | High — designed specifically against DPI | Regions with active probing / firewall analysis |
| SOCKS5 | 1996, RFC 1928 (IETF) | None natively | Fast (thin relay, no encryption overhead) | None on its own — needs an outer layer | Per-application routing, foundation for other tools |
How to think about the tradeoffs
Speed vs. stealth is the central tension. WireGuard is the fastest of the group because it does the least extra work — but that efficiency comes from a distinctive, easily fingerprinted packet structure. VLESS and Shadowsocks trade a small amount of raw throughput for traffic that's much harder to distinguish from ordinary encrypted web browsing.
Age isn't a weakness. OpenVPN and SOCKS5 are respectively 25 and 30 years old, and both are still in daily use — not because nothing better has been invented, but because their simplicity and long audit history make them dependable fallbacks when newer protocols are blocked or unavailable.
No protocol solves everything alone. This is why MiTiVPN, like most serious circumvention tools, doesn't pick just one. A WireGuard-based core provides speed; a VLESS/XTLS-inspired obfuscation layer makes the traffic boring to watch; OpenVPN remains available as a compatibility fallback; and a local SOCKS5 interface lets advanced users route individual apps selectively.
