firecloud-net

P2P networking layer for FireCloud using libp2p with metadata hiding features.

Overview

Provides peer-to-peer networking with privacy features:

P2P messaging: Direct peer-to-peer communication
NAT traversal: Hole punching and relay support
Metadata hiding: Fixed-size messages and timing obfuscation
DHT: Kademlia for peer discovery
mDNS: Local network discovery

Usage

use firecloud_net::{FireCloudNode, NodeConfig};

// Create a node
let config = NodeConfig {
    port: 0,
    enable_mdns: true,
    bootstrap_peers: vec![],
    bootstrap_relays: vec![],
};

let mut node = FireCloudNode::new(config).await?;

// Send a friend request
node.send_friend_request(&peer_id, Some("Alice".to_string()));

// Poll for events
while let Some(event) = node.poll_event().await {
    // Handle events
}

Features

libp2p integration: Modern P2P networking stack
Request-response protocol: Reliable message delivery
Metadata hiding: All messages padded to 1024 bytes
Friend verification: Only accept messages from friends
Delivery confirmations: Know when messages are received

Privacy

This crate implements metadata hiding to protect communication patterns:

Fixed 1KB message size (regardless of content length)
Random timing delays (100-500ms)
Content encryption
Friend-only messaging
