Layer 2 blockchains (L2s)

Layer 2 blockchains, also known as L2 solutions, enhance scalability by processing transactions off the main chain while maintaining security. Lightning Network, Optimism, and Arbitrum speed up transactions and reduce fees on networks like Bitcoin and Ethereum. These solutions improve efficiency for DeFi, NFTs, and payments without compromising decentralization. L2 blockchains ensure faster, cheaper, and more scalable blockchain experiences.
