Tor is a free, open-source network that routes traffic through three volunteer-run relays with layered encryption — designed for anonymity, not speed.
Explanation
A Tor connection encrypts your traffic in three layers and routes it through three relays chosen from a global pool — an entry guard, a middle relay, and an exit relay. Each relay knows only its immediate neighbours; no single relay knows both who you are and what you asked for. The destination sees the exit relay's IP. Tor makes correlation attacks expensive but not impossible, and severely limits speed compared to a single-hop proxy or VPN. Tor is the tool when anonymity is more important than performance. For simple unblocking or region access, a web proxy or VPN is usually a better fit — cheaper (in speed) for the same practical result.
