Layer 2 Scaling Explained: Optimizing Ethereum Performance with Optimistic and Zero-Knowledge Rollups

Ethereum’s scalability limitations have long been a hurdle for DeFi transactions, as its base layer can process only a few transactions per second. To address this, developers rely on Layer 2 solutions – technologies built on Ethereum that enhance efficiency and performance without compromising security or decentralization. This article explores the two main types of Layer 2: Optimistic Rollups and Zero-Knowledge (ZK) Rollups.
