Layer-2 Expansion

Definition

Layer-2 expansion describes the ongoing development and adoption of scaling solutions built atop a foundational blockchain, such as Ethereum. These solutions process transactions off the main chain, significantly boosting throughput and reducing fees. Technologies like optimistic rollups, zero-knowledge rollups, and sidechains represent common approaches to Layer 2 scaling. This advancement is crucial for supporting increased user activity and the proliferation of decentralized applications.
