Quick Start

Add this to your Cargo.toml:

[dependencies]
saorsa-core = "0.2.6"

Basic DHT Node

use saorsa_core::{Network, NetworkConfig, NodeId};
use tokio;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create a new network node
    let config = NetworkConfig::default();
    let mut network = Network::new(config).await?;
    
    // Start the network
    network.start().await?;
    
    // Store some data
    let key = b"example-key";
    let value = b"example-value";
    network.store(key, value.to_vec()).await?;
    
    // Retrieve the data
    if let Some(retrieved) = network.retrieve(key).await? {
        println!("Retrieved: {:?}", retrieved);
    }
    
    Ok(())
}

Four-Word Addresses

use saorsa_core::NetworkAddress;

// Create from IP:port
let addr = NetworkAddress::from_ipv4("192.168.1.1".parse()?, 9000);

// Get four-word representation
if let Some(words) = addr.four_words() {
    println!("Address: {}", words);
}

// Parse from four-word format
let addr = NetworkAddress::from_four_words("alpha-beta-gamma-delta")?;

MCP Server

use saorsa_core::mcp::{McpServer, McpConfig};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let config = McpConfig::default();
    let server = McpServer::new(config).await?;
    
    // Start MCP server
    server.start().await?;
    
    Ok(())
}

Placement System

Saorsa Core includes an advanced placement system for optimal distribution of erasure-coded shards across the network:

use saorsa_core::placement::{
    PlacementEngine, PlacementConfig, GeographicLocation, NetworkRegion
};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Configure placement system
    let config = PlacementConfig {
        replication_factor: (3, 8).into(), // Min 3, target 8 replicas
        byzantine_tolerance: 2.into(),      // Tolerate up to 2 Byzantine nodes
        placement_timeout: Duration::from_secs(30),
        geographic_diversity: true,
        weights: OptimizationWeights {
            trust_weight: 0.4,        // EigenTrust reputation
            performance_weight: 0.3,   // Node performance metrics
            capacity_weight: 0.2,      // Available storage capacity
            diversity_bonus: 0.1,      // Geographic/network diversity
        },
    };
    
    // Create placement engine
    let mut engine = PlacementEngine::new(config);
    
    // Place data with optimal shard distribution
    let data = b"important data to store";
    let decision = placement_orchestrator.place_data(
        data.to_vec(),
        8, // replication factor
        Some(NetworkRegion::NorthAmerica),
    ).await?;
    
    println!("Placed {} shards across {} nodes", 
             decision.shard_count, 
             decision.selected_nodes.len());
    
    Ok(())
}
