The Ethereum Foundation is prioritizing security with a goal of 128-bit provable security for zkEVMs by 2026, shifting focus from speed to stability.

#Why Is the Ethereum Foundation Prioritizing Security?

The Ethereum Foundation has made a significant shift in its priorities, now placing a strong emphasis on security rather than speed. This change reflects a commitment to attaining 128-bit provable security for Layer 1 zero-knowledge Ethereum Virtual Machines (zkEVMs) by the end of 2026. Participating teams are required to adopt official tools and meet progressive security benchmarks as part of this initiative.

What Is the Roadmap to Enhanced Security?

The approach consists of a clear three-stage roadmap aimed at fortifying security measures over the next few years. The first stage involves a comprehensive security assessment slated for early 2026. Following this assessment, the second phase aims for a minimum of 100-bit provable security by the middle of 2026, which includes establishing explicit proof-size limitations. The final phase targets achieving full 128-bit provable security with reduced proof sizes and formal soundness arguments by the end of 2026.

Why Are These Changes Important?

Recent advancements in cryptography provide a solid foundation for reaching these ambitious targets. It is crucial to stabilize zkEVM architectures now to facilitate formal verification processes. This stabilization is vital for ensuring long-term security in the Ethereum ecosystem. By shifting from experimental performance to foundational robustness, the Ethereum Foundation aims to build a more secure infrastructure for all stakeholders involved.
