Ethereum Foundation Outlines Three-Stage Roadmap to Stronger zkEVM Security
- Ethereum is moving toward a strict, phased zkEVM security roadmap, aiming to achieve a 128-bit provable security standard by 2026.
- By addressing major performance bottlenecks, the network is now prioritizing long-term cryptographic resilience.
Ethereum is reinforcing a very strict, phased zero-knowledge Ethereum Virtual Machine (zkEVM) security roadmap, up to in a 128-bit provable security standard by 2026. With performance challenges mainly being addressed, the network is now expanding its priority toward cryptographic resilience, as well as supporting long-term scalability and institutional adoption.
To address the challenges, the Ethereum Foundation outlined a three-stage roadmap to strengthen zkEVM security: first, a unified security assessment in early 2026 using an official measurement tool that can show real-world security levels; second, a mid-2026 requirement for zkEVMs to reach at least 100-bit provable security; and third, a final move to 128-bit provable security by year-end, paired with smaller and more efficient proofs.
Ethereum Commits to a Clear Path for zkEVM Security
To reach this goal, the foundation formalized the roadmap with strict compliance expectations. The final phase, known as codenamed H-star—also introduces tighter proof size constraints of up to 300 KiB and requires formalized recursion-architecture guarantees.
As highlighted earlier, the Foundation announced Ethereum’s shift toward full zero-knowledge proof integration. Under this model, validators will verify state transition proofs instead of re-executing transactions, effectively making Layer 1 proof-centric. The transition follows major zkEVM performance improvements, with proof generation times falling from minutes to seconds and costs declining sharply. With efficiency challenges largely resolved, cryptographic security now stands as the primary remaining risk for Ethereum’s Layer-2 ecosystem.
Ethereum Combines Between Security and Scalability
After zkEVMs, Ethereum nevertheless is now reinforcing security through protocol-level scalability upgrades. Thus, a major network upgrade scheduled for the second half of 2026 is expected to introduce Verkle Trees and state and history expiry, significantly reducing storage requirements for node operators and improving client efficiency.
With standardized security metrics and shared tooling, Ethereum aims to get zkEVMs increased to institutional-grade reliability, supporting higher-value use cases ranging from settlement layers to cross-chain infrastructure.
As of press time, Ethereum (ETH) is trading at $3,032.61, with an increase of 1.14% over the past day, though decreased of 3.8% over the past week. See ETH price chart blow.
