Scroll is a Layer 2 scaling solution for Ethereum that utilizes zk-Rollups to enhance scalability and reduce transaction costs while maintaining high security. By batching multiple transactions off-chain and verifying them with zero-knowledge proofs, Scroll ensures efficient and secure processing. It aims to provide a seamless user experience and support a wide range of decentralized applications (dApps). Scroll enhances Ethereum's capabilities without compromising its core principles of decentralization and security.
