Ethereum ZkEVM Performance Surpasses 16 Seconds, 2026 Security Roadmap Unveiled

In accordance with Jinse, the zkEVM ecosystem has achieved a major performance breakthrough, reducing Ethereum block proof time from 16 minutes to 16 seconds, with a 45-fold cost reduction. On December 18, the Ethereum Foundation (EF) announced the implementation of real-time proof mechanisms and the removal of performance bottlenecks, but emphasized that reliability remains the key challenge. Multiple zkEVMs based on the STARK algorithm have recently seen their security levels decline due to invalidated mathematical conjectures. EF has set a three-phase security roadmap for 2026, aiming to achieve 128-bit provable security by year-end. Core tools like WHIR and JaggedPCS will be used to optimize proof generation and reduce computational waste. However, challenges remain, including the lack of on-chain deployment of real-time proofs and uncertainty around team progress. Post-target achievement, zkEVMs could support higher Ethereum gas limits and enhance L1 as a trusted settlement layer.
