Ethereum Glamsterdam upgrade activated on Sepolia testnet, gas cap increased to 200 million

The Ethereum Glamsterdam upgrade was activated on the Sepolia testnet on October 6th, raising the block gas limit to 200 million, approximately 3.3 times the current main network's 60 million gas. The upgrade includes 18 EIPs, introduces a mechanism for separating proposers and builders within the protocol, supports parallel client verification, and increases the upper limit of smart contract code size. Ethereum Foundation researcher Tony Valstedt stated that after the upgrade, the client execution efficiency has been improved, and the time for Geth to process 40 million Gas blocks has been reduced from about 115 milliseconds to 30 milliseconds. Glamsterdam is expected to be deployed on the Hoodi test network on October 27th, with the main network upgrade target set for the fourth quarter of 2026.
