Anonymity networks are systems designed to protect users' identities while they browse the internet. They work by routing internet traffic through multiple servers, making it difficult to trace the original source of the data. This helps users maintain privacy and security, especially when accessing sensitive information or communicating in restrictive environments. One well-known example of an anonymity network is Tor, which stands for "The Onion Router." Tor encrypts user data and sends it through a series of volunteer-operated servers, or nodes, before reaching its final destination. This layered approach enhances privacy, allowing users to explore the web without revealing their identities.
