Layer 2 (L2) solutions are protocols built on Layer 1 blockchains like Ethereum or Bitcoin to enhance scalability, speed, and cost-efficiency while maintaining security. They process transactions off-chain or on parallel networks, batching them for L1 settlement. Types include rollups (Optimistic, ZK), state channels (Lightning Network), and sidechains (Polygon). L2s offer high TPS, low fees, and fast transactions, supporting DeFi, NFTs, and gaming. Examples include Arbitrum, zkSync, and StarkNet. They address L1 limitations, driving blockchain adoption without compromising decentralization
