Gnosis and Zisk have unveiled a proposal for an "Ethereum Economic Zone" (EEZ) framework aimed at enhancing interoperability between the Ethereum mainnet and various Layer 2 networks. The initiative seeks to streamline operations by sharing infrastructure, thereby reducing redundant development and technical friction while improving user experience. The Ethereum Foundation is backing this project financially. The EEZ framework plans to address Layer 2 ecosystem fragmentation by establishing a unified execution environment and defaulting to ETH as the payment mechanism.
