I2p-cp

: Since I2P is a packet-switched network where messages can be lost or delayed, I2CP is inherently asynchronous, allowing applications to manage their own reliability or use the built-in streaming library for TCP-like behavior. The Initialization Process

: The client requests the current network time from the router via GetDate and SetDate messages.

Notifies the client that a new message has been received from the network. i2p-cp

I2CP operates as a message-based protocol, facilitating communication between two primary components: the (the application) and the Router (the I2P node).

The is the standard interface through which client applications interact with an I2P router to send and receive data across the anonymous network. By decoupling the application logic from the complex routing and encryption tasks of the network, I2CP allows developers to build privacy-focused tools—such as secure messaging or file-sharing systems—without needing to implement the underlying peer-to-peer (P2P) protocol themselves. Core Functionality and Architecture : Since I2P is a packet-switched network where

: The client application and the I2P router can reside on the same machine or different ones, communicating over a local or network socket.

To establish a connection through the network, a client follows a specific handshake and setup sequence via I2CP: Core Functionality and Architecture : The client application

Instructs the router to deliver a payload to a specific I2P Destination.
