# Layer-2 Design

### What is a Layer-2?

A Layer 2 (L2) blockchain enhances Ethereum’s scalability by batching and executing transactions off-chain before settling them on Ethereum. This reduces congestion, lowers fees, and improves transaction throughput without sacrificing security. Revolution is a high-performance L2, purpose-built for staking-powered applications, enabling fast, low-cost, and composable staking interactions while inheriting Ethereum’s security.

Revolution is an open-source platform for sovereign ZK rollups, allowing it to efficiently batch transactions, generate validity proofs, and settle on Ethereum. As a Zero-Knowledge (ZK) Rollup, Revolution ensures instant finality, reduced fees, and strong security guarantees by verifying transactions cryptographically before posting them on-chain. Unlike Optimistic Rollups, which rely on fraud proofs and dispute periods, ZK Rollups provide immediate transaction validity - making them ideal for staking economies, DeFi, and high-frequency applications.
