  Well, there's also the Ethereum network's layer 2 solution called Optimistic Rollups. It is designed to improve scalability and reduce transaction costs on the Ethereum blockchain. Optimistic Rollups bundle multiple transactions together and submit them as a single transaction to the Ethereum mainnet, thereby increasing the network's capacity. Many decentralized applications (dApps) and decentralized finance (DeFi) projects are exploring Optimistic Rollups to enhance their performance.
