Understanding .onion addresses and how onion services work
Onion services use the special .onion domain to let people browse and publish content anonymously through the Tor network. They provide more private ways to host websites, share files, communicate, and even access popular sites over secure Tor connections.
Onion services allow people to browse but also to publish anonymously, including publishing anonymous websites.
Onion services are also relied on for metadata-free chat and file sharing, safer interaction between journalists and their sources like with SecureDrop or OnionShare, safer software updates, and more secure ways to reach popular websites like Facebook.
These services use the special-use top level domain (TLD) .onion (instead of .com, .net, .org, etc.) and are only accessible through the Tor network.
