Surge: Supercharging Ethereum

Surge is a rollup framework built on a modified Taiko Alethia stack that aims to bring rollups into tighter integration with Ethereum L1. According to the text, it targets synchronous composability, atomic L1 ↔ L2 execution, shared liquidity, and Stage 2 security, and it is designed to work alongside the Ethereum Economic Zone. The text says recent advances in real-time proving make synchronous composability practically feasible today, with sequencing and proving merged into a single step for seconds-level finality. It also states that early deployments are already running and that the framework, documentation, and experimental deployments are available now.
