CAMBIUM: Multi-Chain Node Interlink with WASM Balancing

Version: 0.1.0-alpha Status: Alpha Release - Development/Testing Only Author: cdx - cd@rolling.ventures

A proof-of-concept implementing universal blockchain interoperability with WebAssembly-powered intelligent node balancing across Bitcoin, Lightning Network, and Ethereum.

Overview

CAMBIUM Alpha demonstrates the foundational capability of connecting multiple blockchain networks through a unified coordination layer with high-performance node balancing powered by WebAssembly. This alpha release implements fully functional bridges for three major networks with intelligent routing and real-time monitoring.

Known Limitations

⚠️ Alpha Release - Development Only

Transactions are simulated, not executing real on-chain operations
No database persistence for transaction history
No authentication on API endpoints
Single instance only (no horizontal scaling)
Development networks only (regtest/testnet)

DO NOT USE WITH REAL FUNDS OR ON MAINNET

Security

This is alpha software for development and testing only:

❌ No security audits performed
