L2 (Layer 2)

Scaling solutions built on top of L1 blockchains that process transactions off the main chain before settling final states to the base layer. L2s like Arbitrum, Optimism, and Polygon significantly increase transaction throughput and reduce costs while inheriting security from their underlying L1. These solutions include rollups, state channels, and sidechains, enabling faster and cheaper transactions without compromising the decentralization and security guarantees of the base blockchain.
