The Ethereum ecosystem continues to advance its technical roadmap with the Glamsterdam upgrade, a structural update scheduled to go live on the Sepolia testnet on October 6. This step prior to the main rollout aims to optimize block creation and adjust network fees.
The deployment of Glamsterdam on the Sepolia test network
The ecosystem developers have The Glamsterdam update is scheduled to be activated on the Sepolia test network on October 6th.This milestone marks a crucial phase in the ongoing development of Ethereumallowing engineers and node operators to test new features in a secure environment before their deployment on the mainnet.
For the transition to be successful, the Ethereum Foundation has specified that node operators on Sepolia must update both their execution layer and consensus layer clients before the activation date. This client duality is a fundamental feature of the network architecture since its transition to Proof of Stake (PoS), where the execution layer handles transactions and smart contracts, while the consensus layer is responsible for validation and overall blockchain security.
Proponents-Builders Separation (PBS): A Structural Change
One of the most significant changes introduced by Glamsterdam is the native integration of proposer-builder separation (PBS). Until now, the network relied heavily on external middleware to manage how transaction blocks are assembled and proposed.
With this update, the transfer of responsibilities between specialized block builders (who order transactions to maximize efficiency) and validators (who propose the block to the network) will be directly integrated into the Ethereum core protocol. This technical move is designed to reduce reliance on third-party solutions, mitigating potential centralization risks and improving transparency in block creation.

Block-level access lists and new Gas structure
In addition to the validation changes, Glamsterdam will introduce block-level access lists. This technical feature will efficiently log the accounts and storage locations used during each block's processing, optimizing how nodes access and verify historical and state data.
In parallel, the update will implement a revision to the Gas pricing structure. The goal is for fees to more accurately reflect the true cost of creating and accessing data within the network. The Ethereum Foundation has warned that smart contracts that rely on fixed Gas allocations or have hardcoded Gas limits may require modifications by their developers to continue functioning correctly after the update.
The path to Hegotá in 2027 and the end of traditional forks in the road
Although Glamsterdam has a release date for Sepolia, the developers have not yet established a definitive timeline for its deployment on the Hoodi testnet (focused on validators) or the mainnet. However, the ecosystem's long-term vision is already focused on the next major milestone: the Hegotá upgrade, projected for 2027.
Ethereum's co-founder, Vitalik Buterin, recently indicated that Hegotá could represent the last "normal" fork of Ethereum. From that point forward, the network's development is slated to pivot toward much more advanced technologies, including the implementation of recursive STARKs, automated formal verification systems, deep consensus optimizations, and the integration of quantum-resistant cryptography. These advancements aim to prepare the infrastructure for the coming decades, ensuring its scalability and resilience against future technological threats.
FAQ
What is the Sepolia test network?
Sepolia is one of Ethereum's leading testnets. It functions as a secure and controlled environment where developers can test protocol updates, smart contracts, and decentralized applications without risking real funds before launching them on the mainnet.
What does the proponents-builders separation (PBS) mean?
It's a mechanism that divides the task of creating blocks into two distinct roles. Builders are responsible for efficiently grouping and ordering transactions, while proposers (validators) simply select and propose the constructed block to the network, improving the protocol's decentralization.
How will Glamsterdam affect network fees?
The update will adjust how Gas is calculated to better reflect the cost of processing and storing data. This means that some operations may see their costs modified, requiring smart contract developers to review their code if they use fixed Gas limits.
When will Glamsterdam arrive on the Ethereum mainnet?
Currently, the developers have not set an exact date for the mainnet release of Glamsterdam. The deployment on Sepolia on October 6 will serve to assess its stability before scheduling the next phases of implementation.
The Glamsterdam schedule underscores the developer community's ongoing commitment to technical improvement and scalability of the blockchain infrastructure. By testing these innovations first in environments like Sepolia, the main network is guaranteed to maintain its stability as it evolves to meet future technological demands.
With an eye toward long-term upgrades like Hegotá, the ecosystem demonstrates meticulous planning that seeks to balance immediate innovation with long-term security, paving the way for the adoption of advanced cryptography and next-generation verification systems.
