Layer 2 solutions, such as Optimistic Rollups and zk-Rollups, are built on top of Ethereum to enhance scalability by processing transactions off-chain while still relying on Ethereum’s security. These solutions significantly reduce transaction costs and congestion on the Ethereum network, enabling faster and cheaper transactions. By offloading the majority of computation, Layer 2 helps Ethereum handle more transactions, improving user experience, especially during high-demand periods. This also makes decentralized applications (dApps) more efficient, as users are less burdened by high gas fees, which can make Ethereum more attractive for both developers and users.
