 This application can establish tcp and udp tunnels to map local or remote application ports. It does not require a public network. If the two nodes cannot be directly connected, there will be other nodes for relay forwarding, data end-to-end encryption, and relay node Unable to view data.
 
+The underlying transmission can be implemented using quic, tcp, package websocket, and webtransport, using the noise protocol to encrypt the transmission, with its own nat, which can be used in multi-layer combinations.
+
 ## working principle
 
 Computer a opens the application and maps a port, computer b opens the application, connects to computer a, and the port of computer a is mapped to the port 127.0.89.1 of this machine.

 本应用可以建立tcp、udp隧道，把本地或者远程应用端口映射出来，不要求有公网，如果双方节点无法进行直连，会有其它节点进行中继转发，数据端对端加密，中继节点无法查看数据。
 
+底层传输可以使用quic、tcp、package websocket、webtransport实现，使用 noise 协议加密传输，自带nat，可以多层组合使用。
+
 ## 工作原理
 
 电脑a打开本应用，把一个端口映射出来，电脑b打开本应用，连接电脑a，电脑a的端口映射到本机的127.0.89.1端口下。
