The Ethereum Foundation published an article explaining the collaborative vision between L1 and L2, clarifying the role positioning of each layer
The Ethereum Foundation today released a systematic explanation regarding the evolution of the roles of L1 and L2. The core point indicates that as the ecosystem matures, the primary goal of L2 has shifted from "scaling Ethereum" to "providing differentiated functions, customized services, and autonomous controllable areas," while scaling has become a secondary focus.
The Foundation has redefined the roles of L1 and L2 as follows:
· L1: As a permissionless, highly resilient global settlement layer, it undertakes the functions of shared state, liquidity, and DeFi hub, and must continue to scale while maintaining censorship resistance, open source, privacy, and security.
· L2: While developing its own on-chain economy, it will extend Ethereum's core attributes to a broader user base, forming a "full-spectrum" ecosystem.
The Foundation clarifies that L2s with the highest integration with L1 should pursue synchronous composability, complete interoperability, shared liquidity, and Stage 2 mechanisms. A large number of L2s with diverse business models and technical expertise will continue to play an important role, providing functionalities that L1 does not possess.
The Ethereum Foundation stated that it will continue to invest in technology to help L2 smoothly extend L1's core attributes and securely access cross-layer liquidity, while emphasizing that L2 must maintain transparency and verifiability of its security attributes.
