Buterin calls for hard cap on Ethereum proving cost per unit of block gas
- —Buterin set three priorities: matching execution to spec, bounding prover cost to gas, and securing the proof system
- —EIP-7904 recommends no compute gas repricing but explicitly excludes ZK proof generation from its analysis
- —ZKsync reported one RTX PRO 6000 GPU proved 99% of 7,200 mainnet blocks in under 10 seconds each
- —Nethermind found precompiles and division are relatively expensive to prove per unit of gas
Why it matters: A proving-cost cap will determine which Ethereum blocks ZK provers can confirm on time and how much hardware operators must reserve.
