Scroll is a Layer 2 Ethereum scaling solution using zero-knowledge rollups (zk-rollups) to boost scalability, cut transaction costs, and maintain security and decentralization. It integrates zkEVM to ensure compatibility with Ethereum smart contracts while improving throughput. Scroll’s architecture includes settlement, sequencing, and proving layers, working together to handle transactions, generate proofs, and secure finality. Collaborating with PSE and using Halo2, Scroll optimizes hardware for efficient proof generation, enabling high transaction volumes and providing a robust, scalable foundation for Ethereum’s evolving ecosystem.
