The Ethereum Foundation has released a statement on the evolution of the roles of L1 and L2, stating that the goal of L2 has shifted from scalability to providing differentiated features and customized services. As the global settlement layer, L1 must maintain censorship resistance and security, while L2 extends Ethereum's core attributes and emphasizes high integration and security with L1.

ChainCatcher news, the Ethereum Foundation today released a systematic explanation of the evolution of roles between L1 and L2. The core point highlights 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,” with scaling taking a secondary position.

The Foundation has redefined the roles of L1 and L2 as follows:

· L1: Serving as a permissionless, highly resilient global settlement layer, responsible for shared state, liquidity, and DeFi hub functions, while continuously scaling under the premise of maintaining censorship resistance, open-source, privacy, and security.

· L2: While developing its own on-chain economy, L2 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 functions that L1 does not possess.

The Ethereum Foundation stated that it will continue to invest in technology to help L2 more smoothly extend L1’s core attributes and safely access cross-layer liquidity, while emphasizing that L2 must maintain the transparency and verifiability of its security properties.
