Cross-chain General Message Passing Protocol via Eternal Bridge

This paper introduces the Eternal General Message Passing Bridge design, addressing the increasing need for interconnection among blockchain-based applications. Security challenges inherent to individual blockchains are compounded in cross-chain communication protocols. We analyze existing bridge protocols, combining their strengths for secure General Message Passing between diverse blockchains. The paper outlines the high-level architecture, key components, purposes, and data flow within connected chains, providing an innovative cross-chain solution.
