L2 Interoperability

Definition ∞ L2 interoperability refers to the ability of different Layer 2 scaling solutions, or Layer 2 solutions with the Layer 1 base chain, to seamlessly exchange assets and information. This allows applications and users to move between various scaling solutions without friction or significant delays. It aims to create a cohesive ecosystem where distinct L2 protocols can interact efficiently. Such interoperability is vital for a connected and liquid decentralized finance landscape.
Context ∞ Achieving robust L2 interoperability is a primary goal for the continued growth and user adoption of blockchain scaling technologies. Key discussions involve the development of standardized communication protocols and secure bridging mechanisms between different rollups and sidechains. Future developments are focused on generalized message passing systems and shared sequencing layers to enable more efficient and trust-minimized interactions across the Layer 2 spectrum.
