Layer-2
A scaling solution built on top of a Layer-1 blockchain that processes transactions off the main chain while inheriting its security. Examples include Optimism and Arbitrum.
A Layer-2 is a scaling solution built on top of a Layer-1 blockchain. It processes transactions off the main chain while inheriting the security guarantees of the underlying Layer-1. The goal is to increase throughput and reduce transaction costs without sacrificing decentralization or security. Common Layer-2 approaches include optimistic rollups (Optimism, Arbitrum, Base), zero-knowledge rollups (zkSync, StarkNet), and state channels. Layer-2 solutions depend on their parent Layer-1 for final settlement and security, creating a hierarchical relationship between the two layers.
