The three protocols at a glance

Shadowsocks (SS) is a SOCKS5-style proxy with built-in encryption, originally created in China. V2Ray is a meta-framework that supports many transports including VMess, VLESS, Trojan, Reality and Shadowsocks. MTProto is Telegram's native protocol, repurposed as a proxy. Each has different design goals: SS for general bypass, V2Ray for sophisticated obfuscation, MTProto for Telegram-specific bypass.

Censorship resistance in 2026

V2Ray with the Reality protocol currently provides the strongest GFW resistance, but it is complicated to set up and requires a paid server. Shadowsocks is heavily targeted in China and increasingly in Iran. MTProto with "ee" obfuscation is the easiest of the three and survives well for Telegram-specific use, though it cannot proxy other apps.

Performance benchmarks

On a 100 Mbps line from Tehran to Frankfurt, our 2026 measurements: TGFast MTProto 94 Mbps, V2Ray with WS+TLS 89 Mbps, Shadowsocks 91 Mbps. Latency: MTProto 38 ms, V2Ray 44 ms, SS 41 ms. The differences are small; protocol choice is more about resilience than speed.

Setup complexity

MTProto: one tap on a tg:// link, total time 30 seconds. Shadowsocks: download a client (Outline, ShadowsocksX-NG), import a server URL, total time 3-5 minutes. V2Ray: install a client (V2RayN on Windows, Shadowrocket on iOS), paste a complex JSON config, total time 5-15 minutes. For non-technical users, MTProto wins decisively.

Cost

TGFast MTProto is free forever. Public Shadowsocks lists exist but are unreliable; reliable SS service costs $2-8/month. V2Ray service costs $3-10/month. For Telegram-only use, MTProto is the obvious budget choice.

When to use what

MTProto: Telegram only, free, easy. Shadowsocks: any app, paid, easy-medium difficulty. V2Ray: any app, paid, medium-hard difficulty, best resilience. Many users in heavily censored countries pay for V2Ray for general browsing and use TGFast on top for guaranteed Telegram reliability.

Privacy comparison

All three encrypt traffic between client and server. None of the three reveal message content to a passive observer. MTProto is unique in that the proxy operator cannot read Telegram messages even in principle (they are double-encrypted by Telegram itself). With SS and V2Ray, the operator can theoretically log full plaintext for unencrypted destinations.

Frequently Asked Questions

How is MTProto different from SOCKS5 or Shadowsocks?

MTProto is Telegram's native protocol, so traffic looks indistinguishable from a normal Telegram connection to deep packet inspection. SOCKS5 is a generic proxy with a recognizable handshake; Shadowsocks adds obfuscation but still requires the operator to defend their port and keys against probing. MTProto with Fake-TLS adds a TLS-1.3-mimicking handshake that has proven the hardest of the three to fingerprint.

Why does the secret start with "dd" or "ee"?

The leading byte is a magic prefix that tells the Telegram client which obfuscation mode to negotiate. "dd" enables MTProto 2.0 random padding to defeat traffic analysis; "ee" indicates Fake-TLS mode where the entire session is wrapped in a TLS 1.3 handshake. Both are interoperable with all modern Telegram clients.

Can a network operator detect that I am using an MTProto proxy?

A determined operator can sometimes flag suspicious flows by timing analysis, but the encrypted payload itself is opaque. Fake-TLS makes detection significantly harder because the handshake mimics a real HTTPS site (including SNI, ALPN and certificate exchange). Even when flagged, blocking is per-IP, not per-protocol — which is why TGFast rotates IPs continuously.

Does an MTProto proxy add real cryptography or only obfuscation?

Both. The MTProto 2.0 transport adds AES-256-IGE encryption between client and server with per-session keys derived from the shared secret, and Fake-TLS wraps that channel inside a real TLS 1.3 handshake. Even if the proxy operator were malicious, they could not decrypt the inner Telegram session — that key is negotiated end-to-end with Telegram's data centres.

How does TGFast pick which servers to deploy and where?

We monitor latency and packet loss from probe nodes in 14 cities across the regions hit hardest by Telegram restrictions. New servers are spun up where the median latency to nearby ISPs falls below 80 ms and where the upstream provider has historically resisted ISP take-down requests. Capacity is rebalanced weekly.
