Summary
TLDR: Vitalik Buterin is cautious about building complex features on Layer 2 scaling solutions on Ethereum as they may introduce extra risk. He believes that adding sophisticated features to the base layer could simplify L2s and reduce code burden. Buterin has been focused on security and recently expressed interest in using AI for auditing Ethereum’s code. His stance on L2s has changed from keeping Ethereum mainnet simple to considering adding more features for security reasons.
Key Points
1. Vitalik Buterin believes that not all complex features developers want on Ethereum should be built on Layer 2 scaling solutions.
2. Layer 2 solutions like Optimism, Polygon, and Arbitrum are currently processing about 75 transactions per second, compared to Ethereum mainnet’s 12 TPS.
3. Buterin argues that while L2s inherit security guarantees from the L1 they sit on, complex features built on L2s instead of the base layer can introduce additional risks, potentially resulting in permanent loss of funds.
