Ethereum’s development plans are entering a new phase as the relationship between the base layer (L1) and the growing network of Layer 2 (L2) chains evolves. Recent guidance outlines a shift in priorities, with L2 no longer primarily defined by scaling Ethereum, but by offering differentiated services, custom execution environments, and a clear economic model.
This adjustment reaffirms Ethereum L1’s role as a central hub for payments, liquidity, and decentralized finance, while taking into account changes in technology, market structure, and the growing maturity of the L2 ecosystem.
L1 is positioned as the core payment layer and liquidity layer
Ethereum L1 will continue to operate as a permissionless and resilient foundation for global payments, shared statehood, and capital flows. The network is designed to scale without compromising its core principles of censorship resistance, open source infrastructure, privacy, and security.
At the same time, the ongoing development of zero-knowledge technologies and scaling mechanisms is expected to significantly expand L1 capacity while maintaining decentralization.
This position maintains Ethereum as a primary source of liquidity and adjustment within the broader ecosystem. L1 also provides the security guarantees that L2 networks rely on, reducing the need for independent verification systems and reducing operating costs for emerging chains.
L2 shifts focus to customization and market strategy
In contrast, L2 networks are currently defined by specialized features, governance structures, and the ability to introduce application-specific optimizations. Scaling is still part of that capability, but the primary focus has shifted to differentiation, control, and innovation.
L2 is expected to support a wide range of use cases, including non-EVM environments, enhanced privacy models, alternative transaction sequences, and specialized economic systems. Some networks prioritize ultra-low latency or compliance-oriented designs, while others focus on modular architectures or sector-specific applications.
The level of integration with Ethereum L1 varies depending on L2. Networks seeking deeper collaboration are encouraged to employ mechanisms such as synchronous composability, shared liquidity, and advanced rollup structures. These approaches aim to enhance interoperability and enable seamless access to L1 assets and services.
Mutual reinforcement defines ecosystem growth
The relationship between Ethereum L1 and L2 is structured as a mutually reinforcing system. L2 extends Ethereum’s core properties of security, resiliency, and decentralization to a broader user base, while also serving as a distribution layer for new applications and services.
At the same time, L2 activity contributes to Ethereum’s network effects by increasing demand for ETH, increasing developer participation, and strengthening interoperability between chains. However, both layers are expected to maintain transparency in the security model and ensure that users can evaluate the level of trust and decentralization they provide.
