Glamsterdam test shows Ethereum validators still lack capacity for higher gas limits

Understanding Gas Limits and Transaction Capacity

A higher gas limit does not automatically triple the number of transactions. Gas measures computational effort needed to process operations. A larger block gas limit allows inclusion of more transaction volume, which could ease competition for space during high demand, but does not guarantee lower fees, as users continue to compete for available capacity. The Glamsterdam update adjusts gas consumption for various tasks, so increasing the block budget does not necessarily mean processing more raw transactions. Simple transfers require different resources than complex smart contracts, and the raw transaction rate per second is not identical to gas per block. This update changes how Ethereum manages block production and data access by integrating the roles of transaction assemblers and validators, giving them more time for verification. Blocks will now include a list of affected accounts and stored data, facilitating efficient information retrieval and transaction validation.

Additionally, costs for creating and accessing stored data are modified, which may require developers to retest their contracts and tools in light of the new gas fees. These adjustments are part of Ethereum's broader strategy to improve capacity while maintaining practical network operation. Test Results on Sepolia Show Limited Usage An analysis by CoinDesk of over 25 consecutive blocks on Sepolia found each block used between 52 and 92 million gas, representing 26% to 46% of the total allowed limit. None approached maximum capacity, a situation that could strain network computers. In a separate six-minute voting period, Sepolia produced all 32 scheduled blocks, with 99.97% of eligible staking voting for finality. These results suggest successful block production and a functional voting process, but they do not confirm that validators can sustain blocks with nearly 200 million gas or that this would be safe on mainnet.

The goal of Glamsterdam is not only to increase the block gas budget

The goal of Glamsterdam is not only to increase the block gas budget, but also to improve transaction processing efficiency and recalibrate data management costs. Broader Context in Layer-1 Scalability Race Competition for scalability between Ethereum, Solana, BSC, and Avalanche intensifies. In other Ethereum news, this test is part of a broader layer-1 competition alongside Solana, BNB Chain, and Avalanche. However, these networks use different architectures and capacity metrics, making direct comparison of their maximum throughput claims with Ethereum's per-block gas limit impossible. Solana's slot-time-based approach demonstrates why latency and Ethereum's computational gas budget describe distinct aspects. For Ethereum, the immediate target is increasing space for payments and transactions, while testing changes in transaction processing and data access. The Sepolia blocks analyzed so far have used less than half of the allocated quota.

This turns the result into a demonstration of maneuvering margin, not proof that the network is already processing blocks of nearly 200 million gas at full load. The next reference point will be the Hoodi network, provisionally planned for October 27, pending Sepolia results. Developers have not set a mainnet activation date, and Sepolia figures do not establish a specific increase in transactions per second, nor do they prove safe and sustainable operation at the new limit.
