L2s

L2s, or Layer 2 solutions, refer to secondary frameworks built on top of existing blockchain networks, like Ethereum, to enhance scalability and reduce transaction costs. They facilitate faster transaction processing and can handle a greater volume of transactions compared to the base layer (Layer 1) blockchain. Common L2 solutions include technologies like rollups, sidechains, and state channels, which aim to alleviate congestion on the main blockchain while maintaining security and decentralization.
