JeroP2P: High-Performance Blockchain Networking

JeroP2P is a custom peer-to-peer networking library built in Rust, designed as a high-performance alternative to libp2p for blockchain applications. It features ultra-low latency, deterministic behavior, and seamless Node.js integration.

JeroSHP: AI-Powered Security Layer

Crate	Purpose	Status
jeroshp	AI message & contract verification	✅ Phase 2

JeroSHP (Smart Hybrid Protocol) provides AI-powered message and contract verification as a middleware layer for JeroP2P, acting as an intelligent firewall that prevents malicious content from entering the consensus layer.

Key Features (Implemented)

• Ultra-low latency networking
• High throughput message processing
• Deterministic peer selection and routing
• DoS protection, message integrity, protocol versioning
• AI-powered filtering and verification (JeroSHP)
• Real-time metrics and performance tracking

Prerequisites

• Rust 1.70+
• Node.js 18+ (for bindings)

Quick Start

# Clone the repository
git clone https://github.com/yourusername/JeroP2P.git
cd JeroP2P

# Build the workspace (excluding Node.js bindings for now)
cargo build --release --workspace --exclude jerop2p-node-bindings

# Run basic transport example
cargo run --bin transport_example -p jerop2p-examples

# Run comprehensive Phase 4 security tests
cargo run --bin phase4_security_summary -p jerop2p-examples

# Run AI verification example (JeroSHP)
cargo test -p jeroshp

Example Usage

use jerop2p_messaging::{Message, MessageType, MessageCodec};
use jerop2p_core::PeerId;
use jeroshp::{JeroSHP, VerificationConfig};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Initialize AI-powered message verification
    let mut shp = JeroSHP::new(VerificationConfig::default()).await?;
    
    // Create a message
    let sender = PeerId([1u8; 32]);
    let message = Message::broadcast(
        MessageType::Transaction,
        sender,
        b"transaction_data".to_vec(),
    );
    
    // AI verification before consensus
    let decision = shp.verify_message(&message).await?;
    if !decision.is_allowed() {
        println!("Message blocked: {}", decision.reason());
        return Ok(());
    }
    
    // Process verified message...
    println!("Message verified and processed");
    Ok(())
}
