In a recent article, Ethereum Foundation researcher Toni Wahrstätter pointed out that there are technical challenges in expanding the Ethereum block gas limit and called on the community to remain patient.
The Ethereum community is discussing raising the gas limit, a change that could enhance network capacity but also pose risks to stability and security. Wahrstätter highlighted limitations related to the consensus layer (CL) client specification, which cannot exceed the current 36 million gas threshold without major protocol upgrades.
Meanwhile, Ethereum developers are preparing the Pectra 2 network upgrade to address these challenges. This hard fork includes two key proposals that aim to lay the foundation for higher gas limits.
The first is EIP-7623, which reduces the worst-case block size by mitigating DoS risks and enabling safer capacity increases;
The second is EIP-7691, which increases the target and maximum number of blobs per block, providing empirical data on network performance under higher storage and propagation requirements.
