L2 Migration

Definition ∞ L2 Migration refers to the process of moving decentralized applications and digital assets from a main blockchain, known as Layer 1, to a Layer 2 scaling solution. This shift aims to enhance transaction speed, reduce fees, and improve network throughput by processing transactions off the main chain. Layer 2 solutions then periodically settle batches of these transactions back onto the Layer 1 blockchain, maintaining security guarantees.
Context ∞ L2 Migration is a dominant theme in blockchain development news, particularly for networks like Ethereum grappling with scalability limitations. Projects are actively transitioning to various Layer 2 technologies, such as rollups and sidechains, to accommodate growing user demand and application complexity. The success of this migration is critical for the long-term viability and mainstream adoption of many decentralized applications.
