Frequently Asked Questions
Layer 2s are scaling solutions that process transactions off the main Ethereum chain (L1) while inheriting its security. They offer lower fees and faster transactions. Types include Optimistic Rollups and ZK Rollups.
Optimistic Rollups (Arbitrum, Optimism) assume transactions are valid and use fraud proofs. ZK Rollups (zkSync, Starknet) use cryptographic proofs for instant finality but are more complex to build.
Arbitrum and Optimism have the most DeFi activity. Base (Coinbase) is growing fast. zkSync and Starknet offer ZK technology. Choose based on the dApps you want to use and fee considerations.
