Layer 2 solutions are technologies built on top of existing blockchains (Layer 1) to enhance scalability, reduce transaction costs, and improve efficiency without compromising security. They process transactions off-chain while leveraging the main blockchain’s security. Popular Layer 2 approaches include state channels (e.g., Lightning Network for Bitcoin), rollups (e.g., Optimistic and ZK-Rollups for Ethereum), and sidechains. These solutions enable faster transactions and lower fees, making blockchain applications more practical for everyday use. By handling high transaction volumes off-chain and periodically settling on the main chain, Layer 2 solutions address scalability bottlenecks, fostering broader adoption of decentralized technologies.
