Ethereum’s privacy push hits a numbers problem: one proof needs nearly twice the proposed gas allowance

A Sept. 5 proposal would let some Ethereum nodes accept privacy transactions that exceed a shared validation allowance, without ensuring those transactions travel across the public network. The proposed 100,000-gas guarantee remains below the proof-verification cost reported in a new privacy benchmark.The open change to EIP-8141, Ethereum’s proposed Frames transaction design, was submitted by contributor AnkushinDaniil. It would turn the existing validation maximum into a common floor: nodes would have to propagate qualifying transactions within it, while capable nodes could accept more expensive ones locally. The proposal remains under review.For Tornado Cash and RAILGUN designs studied in the benchmark, replacing off-chain relayers with public submission requires proofs that nodes will accept and pass along. Allowing some nodes to accept heavier transactions would not guarantee wider network support.The proof still exceeds the allowanceThe current EIP-8141 draft caps signature checks and execution in the initial validation phase through payment approval at 100,000 gas. Gas measures computational work here, rather than a fixed fee in dollars. The limit is intended to contain node ...
