The main purpose of Tor bridges is to provide an additional layer of obfuscation and protect the privacy of users in regions with strict internet censorship or surveillance. When a user connects to the Tor network through a bridge, the bridge acts as a gateway, forwarding traffic to the Tor network while keeping the user's connection details hidden from potential adversaries.
