V2Ray 4.7新增了Quic传输方式。基于IETF QUIC标准实现，目前处于测试阶段。初步的实验表明Quic有效减少连接握手的延迟，网页加载速度有明显提升。但传输速度上限，尤其是在丢包率较高的环境下，相比KCP或TCP没有优势。

Mr. Durov launched Telegram in late 2013 with his brother, Nikolai, just months before he was pushed out of VK, the Russian social-media platform he founded. Mr. Durov pitched his new app—funded with the proceeds from the VK sale—less as a business than as a way for people to send messages while avoiding government surveillance and censorship.
Secret Chats are one of the service’s additional security features; it allows messages to be sent with client-to-client encryption. This setup means that, unlike regular messages, these secret messages can only be accessed from the device’s that initiated and accepted the chat. Additionally, Telegram notes that secret chats leave no trace on the company’s services and offer a self-destruct timer.
