Ethereum Layer2 is a key technical solution to the scalability problem. Currently, the most active L2 solutions include two major camps: Optimistic Rollup and ZK Rollup.
Arbitrum — The TVL-Leading Optimistic Rollup
Arbitrum holds the top spot among L2s with a TVL exceeding $2B, and its ecosystem is rich with projects, including star protocols such as GMX and Radiant.
zkSync Era — A Representative ZK Rollup
zkSync adopts zero-knowledge proof technology, offering faster transaction confirmations and higher security. Its ecosystem is developing rapidly, with hundreds of DApps already deployed.
Base — The L2 Launched by Coinbase
Base is operated by Coinbase and is growing rapidly thanks to its massive user base. Gas fees are extremely low, making it suitable for beginners.
Summary
Layer2 is the future of Ethereum, and different solutions each have their own strengths and weaknesses. It is recommended that investors focus on two core metrics: TVL growth and user activity.
