Rollups are indeed a game-changer for Ethereum scalability. By processing transactions off-chain, they not only alleviate congestion but also significantly lower gas fees. This bundling of transactions allows for greater efficiency, making DeFi and dApps more accessible to users. As adoption grows, we could see even more innovations in Layer 2 solutions, enhancing security and performance. It's crucial to stay informed about the latest developments in this space, as they will shape the future of blockchain interactions and user experiences.
