Sentium Bridge Protocol (SBP)

Semantic Bridge Protocol - Intent-Based Cross-Chain Communication

Overview

Sentium Bridge Protocol (SBP) is a standalone cross-chain communication protocol that enables intent-based messaging between different blockchains. Unlike traditional packet-based protocols , SBP preserves semantic context and uses AI-powered routing for optimal cross-chain transactions.

Why Separate Repository?

• ✅ Different chains can use SBP independently (not just Sentium chains)
• ✅ Independent versioning and releases
• ✅ Multiple language implementations (Rust, Go, Python)
• ✅ Focused security audits
• ✅ Bridge developers can contribute without touching core SDK

Features

• Intent-Based Messaging: Preserve semantic context across chains
• AI-Powered Routing: Optimal path finding using graph neural networks
• Quantum-Safe Light Clients: Dilithium5-based state verification
• Multi-Chain Support: Ethereum, Bitcoin, Polkadot, Cosmos, and more
• Context Preservation: Maintain intent context across chain boundaries

Quick Start

use sentium_bridge::{Bridge, Intent, Chain};

// Create bridge instance
let bridge = Bridge::new()
    .add_chain(Chain::Ethereum)
    .add_chain(Chain::Polkadot)
    .build();

// Send cross-chain intent
let intent = Intent::new()
    .from_chain(Chain::Ethereum)
    .to_chain(Chain::Polkadot)
    .action("transfer")
    .amount(100)
    .build();

bridge.send(intent).await?;
