Address blocking
The firewall keeps lists of forbidden websites and servers. Any request to a blocked IP or domain is simply dropped — the page never loads.

Censorship isn't one thing — it's a stack of techniques: blocked addresses, filtered keywords, banned platforms, and surveillance that ties everything to your real identity. Each technique has a counter. Try them below.
The problem
The firewall keeps lists of forbidden websites and servers. Any request to a blocked IP or domain is simply dropped — the page never loads.
Traffic is scanned in real time. Messages containing sensitive words can be silently dropped, and searches for them return nothing.
SIM cards, apps, and accounts require real identities. What you say online can be traced directly back to you and your family.

Encryption scrambles your message so that only the intended recipient can read it. Type below and compare what a censor sees with and without encryption.

Tor wraps your message in three layers of encryption — like an onion — and bounces it through three volunteer relays. Each relay peels exactly one layer, so no single relay ever knows both who you are and where the message is going.
The toolbox
Best for: everyday circumvention. Creates one encrypted tunnel to a server outside the firewall. Fast and simple — but you must trust the VPN provider, and known VPN servers can themselves be blocked.
Best for: anonymity. Three encrypted hops mean no single point knows both ends of the conversation. Slower than a VPN, and often needs "bridges" where Tor itself is blocked.
Best for: reaching blocked services. The same service published at many alternative addresses. Block one, another appears. This is how Convene stays reachable inside Tibet.
