Tor β originally The Onion Router β is a free software project that enables anonymous communication. Unlike regular internet traffic which goes straight from your computer to the destination server, Tor routes your connection through multiple volunteer-run servers, called nodes or relays. Each hop encrypts the traffic again, creating layers of encryption like the layers of an onion.
The result: nobody along the path knows both who you are and where you're going. The first node (entry guard) knows your IP but not your destination. The middle nodes know neither. The final node (exit relay) knows your destination but not your source.
This design makes it incredibly difficult for anyone β ISPs, governments, surveillance agencies β to correlate your online activity with your physical location.
Let's trace what happens when you access a website through Tor:
If one node is compromised, it cannot de-anonymize you alone. Only if all three nodes are controlled by the same adversary simultaneously can someone potentially correlate timing and break anonymity. This is statistically unlikely β but not impossible.
This is where things get interesting. Just as you can browse anonymously with Tor, you can also host services anonymously β this is called a Hidden Service.
A Hidden Service never reveals its real IP address. Instead:
3syxsh7q3h4lhardkw7u4tvezf7exyalf3dh32cox6b6hkoigo2aikid.onion)This is why this site runs on both clearnet and .onion. Same content, two different access methods. For visitors in restrictive environments, .onion bypasses censorship. For everyone else, it's another option.
// INFO: Tor Hidden Services don't need port forwarding or public IPs. Everything happens inside the Tor network. No firewall holes, no exposed ports, no DNS records.
This website is also available as a Tor Hidden Service. If you want to access it anonymously, or if you're in a region where the clearnet domain is blocked, use the address below in your Tor Browser:
Don't have Tor Browser? Download it from the official Tor Project: torproject.org/download
// SECURITY WARNING: Only use the official Tor Browser. Third-party "Tor browsers" from app stores or random websites may contain malware or tracking. Verify the signature. Trust nothing else.
Tor isn't fast. Three hops, multiple encryptions, volunteer bandwidth constraints β it's inherently slower than direct connections. But speed isn't the priority here. Anonymity is.
Common misconceptions:
// SECURITY WARNING: The biggest vulnerability isn't Tor itself β it's user behavior. Downloading files, enabling JavaScript, logging into accounts that identify you β these actions deanonymize you regardless of Tor's strength. Use the Tor Browser. Don't mix identities.
| User Group | Purpose |
|---|---|
| Journalists | Secure communication with sources |
| Whistleblowers | Anonymous leaks (SecureDrop uses Tor) |
| Activists | Organizing under censorship |
| Privacy Advocates | Preventing ISP/government surveillance |
| Security Researchers | Threat intelligence, safe browsing |
| Ordinary Citizens | Avoiding corporate tracking |
The Tor Project is funded by NGOs, government grants (including DARPA historically), and donations. The irony is intentional: sometimes freedom needs funding from systems it critiques.
