Vitalik Buterin Declares Ethereum zkEVM Speed Race Over, Sets Three Security Priorities

Summary

Ethereum co-founder Vitalik Buterin has urged zkEVM developers to prioritize security following progress from ZKsync’s Airbender team. According to Buterin, progress by ZKsync’s Airbender team has shifted attention from proving speed to three security priorities aimed at strengthening transaction verification and keeping computational costs manageable for smaller Ethereum operators.

Ethereum zkEVM Developers Face Three Security Requirements

Buterin’s priority requires mathematical confirmation that zkEVM proofs accurately reflect Ethereum’s execution rules. This requirement would help expose differences between the network’s official specifications and the calculations used by proving systems.

The second priority calls for a strict upper limit on proving costs relative to the gas consumed within each Ethereum block. Such limits would help prevent unusually demanding blocks from imposing disproportionate expenses on proof-generating operators.

Without predictable computing requirements, smaller participants could face greater barriers, concentrating infrastructure among larger organizations. The third priority concerns the cryptographic security of the proof systems themselves, including their underlying mathematical assumptions.

Together, these safeguards address whether proofs represent valid Ethereum activity, remain affordable to generate, and withstand potential security weaknesses.

Ethereum’s broader roadmap explores using zero-knowledge technology to reduce verification workloads without repeating every calculation. The approach depends on trustworthy proofs, making formal verification essential despite faster processing.

Ethereum Price Faces Pressure as Security Debate Advances

Meanwhile, Ethereum (ETH) is trading near $2,365, representing a decline of approximately 15% from its late September high of $2,800. The cryptocurrency faces immediate support at $2,360 and $2,305, while resistance levels at $2,490 and $2,550 remain important barriers to a potential price recovery.

The relative strength index hovered near 38, reflecting weak momentum without establishing whether the cryptocurrency would recover or decline further. Buterin’s recommendations concern Ethereum’s technical infrastructure rather than immediate changes to transaction fees, staking rewards, or token supply.

Developers’ progress on formal verification will determine how confidently zero-knowledge proofs can support Ethereum’s expanding verification requirements across the network while protecting participants from avoidable technical risks.
