: The client sends a protocol version byte (typically 0x2A ) to ensure compatibility.

: The client application and the I2P router can reside on the same machine or different ones, communicating over a local or network socket. i2p-cp

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 : The client sends a protocol version byte

: 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 By decoupling the application logic from the complex

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