A SIMPLE L2 SECURITY AND FINALIZATION ROADMAP

Summary from the TLDR Crypto newsletter

Vitalik Buterin's vision for Ethereum involves advancing L2 security and finality with expanded blob space targets and new high-quality zkEVM options for shorter finality times than optimistic rollups. A proposed 2-of-3 proof system using optimistic, ZK, and TEE-based provers would deliver instant finality under normal conditions and trustlessness when proof systems perform as expected. Standardized proof aggregation layers across Ethereum are required to streamline costs for various apps and L2s and improve interoperability.
