了解 .onion 地址以及洋葱服务的工作原理

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.

洋葱服务允许人们匿名的访问和发布信息，包括架设匿名网站。

另外，洋葱服务可用于提供多种服务：去元数据的聊天和文件共享，如通过 SecureDrop 或 OnionShare 在记者与消息源之间进行互动和资源共享，更安全的软件升级，以及更安全地访问热门网站，如 Facebook。

这些服务使用专用的顶级域名（TLD）.onion（而不是.com、.net、.org 等），并只能通过 Tor 网络访问。

当访问使用洋葱服务的网站时，Tor 浏览器将通过 URL 栏中的洋葱图案来表示连接状态：安全和使用洋葱服务。 如果需要了解更多洋葱服务，请阅读洋葱服务如何工作
