Vitalik Buterin Calls for Hard Ceiling on Ethereum Proving Costs
Vitalik Buterin, known for his work on Ethereum, has proposed a hard ceiling on the costs associated with proving blocks on the Ethereum network. This proposal aims to address the issue of resource consumption, particularly focusing on the use of zero-knowledge proofs (ZK proofs). The update comes after the success of ZKsync, which has seen significant improvements in speed. The proposed ceiling would ensure that the hardest permitted blocks do not exceed a certain resource limit, thereby maintaining predictability in the network's resource consumption. The update notes that while the current analysis in EIP-7904 does not specifically address ZK proof generation, it does not recommend changes to Ethereum's gas schedule, which is currently set for execution measured on a bare CPU.
