chaincraft 0.3.2

//! Chatroom Example
//!
//! Demonstrates the decentralized chatroom protocol built on Chaincraft.
//! Ported from the Python chaincraft examples (chatroom_protocol.py).
//!
//! Features:
//! - Create chatrooms with admin control
//! - Post messages to chatrooms
//! - ECDSA-signed messages for authentication
//!
//! Run with: `cargo run --example chatroom_example`
