Scroll is a layer 2 scaling solution built on Ethereum, focusing on zkEVM technology to offer high throughput and low transaction costs while maintaining compatibility with Ethereum's developer environment.

Scroll's architecture integrates three key components: Scroll nodes, a proof network, and contracts for Rollup and cross-chain bridges. Scroll nodes process Layer 2 transactions, connecting to Ethereum's mainnet for data synchronization and transaction submission. The proof network, equipped with specialized hardware, generates validity proofs for transactions. Rollup and cross-chain bridge contracts facilitate data availability, verify proofs, and enable asset transfers between Layer 1 and Layer 2 networks.
