Glamsterdam update for Ethereum: final stage of development and key EIPs

The Ethereum network is entering a new era: the Glamsterdam upgrade has officially moved into its final development phase. At this point, all planned Ethereum Improvement Proposals (EIPs) have been integrated and are undergoing active testing ahead of the launch of public testnets. Although the exact mainnet activation date has not yet been announced, in my estimation, the update should be expected in the second half of 2026.
This upgrade promises to be one of the most significant in Ethereum's history, second in scale only to the historic Merge in 2022. Key changes include the implementation of ePBS (EIP-7732), which reforms the mechanism for dividing roles between validators and block builders, significantly enhancing the efficiency and decentralization of the transaction confirmation process.

The second most important component is the introduction of Block-level Access Lists (EIP-7928). This technology will optimize gas consumption and speed up the processing of complex transactions, especially in smart contracts. Additionally, the fork includes a major overhaul of gas repricing, which will directly impact the network's economy and user fees.
According to information from Ethereum Foundation developers, Paritosh Jayanti specifically emphasized that Glamsterdam could become the largest update since The Merge. This statement is not without merit: the combination of ePBS, new access lists, and operational cost rebalancing creates a foundation for the next generation of Ethereum scaling, making the network more resilient and ready for mass adoption.
My expert perspective: Glamsterdam is not just another technical update but a strategic step that lays the groundwork for Ethereum's transition to a full sharding architecture. Investors and developers should closely monitor the testnets: the successful implementation of ePBS could act as a catalyst for new growth in staking and the emergence of more complex DeFi protocols.
