Ethereum's cross-chain governance mechanism could benefit from a dedicated proposal coordination layer to streamline decision-making across its multi-chain ecosystem. Such a layer would facilitate efficient communication, consensus, and execution of proposals between mainnet and Layer 2 solutions or sidechains. It could standardize proposal formats, ensure interoperability, and reduce fragmentation risks. Without it, governance may face challenges like misaligned incentives, slow coordination, or conflicting decisions across chains. However, implementing a coordination layer must balance centralization risks against decentralization ethos, ensuring no single entity dominates. Existing frameworks like EIP (Ethereum Improvement Proposals) could evolve to include cross-chain coordination, leveraging smart contracts for automated, transparent voting. This would enhance scalability and cohesion while maintaining Ethereum’s decentralized principles.
