Streaming Protocol

The Ixian Streaming Protocol (S2) is a secure, peer-to-peer communication layer built on top of the DLT Master Node network. It enables end-to-end encrypted, direct messaging between any two Ixian addresses.

Communication is layered. A StreamMessage acts as the secure, routable envelope, while an inner SpixiMessage contains the actual application-level command or data.

Protocol Layers

Layer	File	Description
Envelope	StreamMessage	The outer, secure wrapper that handles S2 network routing, encryption, and signing.
Application	SpixiMessage	The inner, decrypted payload that defines the application-level command (e.g., chat, file transfer).
