PANews reported on April 28 that Ethereum Foundation researcher Toni Wahrstätter posted on the X platform that the current Ethereum execution layer expansion roadmap is progressing smoothly, including continued increase in Gas limit (EIP-7935), historical data expiration (EIP-4444), delayed execution (EIP-7886), block access list (EIP-7928) and block-level warm-up (EIP-7863). The Gas limit has recently been increased from 30M to 36M, and the future goal is to achieve 100M before the Glamsterdam upgrade. The Nethermind team also launched a new test network PerfNet to test shorter time slots and higher Gas limits. The EIP-9698 proposal proposes to achieve exponential growth in the Gas limit within 4 years through default client voting.
