Ethereum Foundation researchers are actively exploring a novel approach to unify the fragmented Layer 2 ecosystem. The goal is to create a seamless, "one-chain" experience for users, overcoming the liquidity and usability challenges inherent in the current multi-chain landscape. This initiative, as reported by The Block, focuses on developing an interoperability layer that would connect the various Layer 2 solutions (rollups, sidechains, etc.) operating on top of Ethereum. By enabling easier communication and asset transfer between these layers, the Ethereum Foundation aims to solve the problem of liquidity fragmentation. Users would benefit from reduced friction, lower costs, and a more cohesive experience when interacting with decentralized applications built on Ethereum. This research signals a significant step towards realizing the full potential of Ethereum's Layer 2 scaling roadmap. ```
