The report focuses on the concept of interoperability within the Superchain ecosystem, emphasizing the need for seamless interaction between users, dApp builders, and chain builders. It begins by defining key concepts of interoperability, including token and messaging bridges, and outlines the challenges that stakeholders face due to fragmented liquidity across chains.
Key sections cover:
Stakeholder Expectations: Examines what users, dApp builders, and chain builders want from the Superchain ecosystem in terms of speed, costs, and security.
Interoperability Solutions: Discusses existing solutions from other ecosystems, particularly Cosmos and EVM interoperability standards, highlighting their trade-offs in achieving seamless communication.
Future Directions: Proposes various approaches for Superchain to enhance interoperability, including shared sequencers and potential zk-rollup developments. The focus is on achieving synchronous atomic execution—ensuring that transactions across chains are either all executed or none are, providing a streamlined user experience.
Conclusion: The report concludes that a decentralized shared sequencer approach could be the most viable path for Superchain, although it requires significant development effort and collaboration with other systems and chains.
Overall, the report emphasizes the importance of establishing robust interoperability methodologies to facilitate a cohesive ecosystem of decentralized applications.
