Ethereum continues to evolve through carefully planned protocol upgrades.
As of mid-2026, attention centres on the next major hard fork known as Glamsterdam.
This upgrade aims to improve how the network builds blocks, processes transactions, and prepares for higher capacity.
The following sections address the questions people ask most often about these upcoming changes.
What is the Glamsterdam Upgrade?
Glamsterdam represents Ethereum’s next coordinated hard fork after earlier 2025 upgrades.
Developers created the name by combining “Gloas” for the consensus-layer changes and “Amsterdam” for the execution-layer updates. As a result, the upgrade targets two critical areas at once.
Moreover, Glamsterdam focuses on reorganising block production and enabling safer parallel processing.
In addition, it prepares the network for higher throughput while addressing long-standing issues around MEV and censorship resistance.
Therefore, many observers describe it as a structural step rather than a simple feature release.
Ultimately, Glamsterdam advances Ethereum’s long-term scaling and sustainability goals.

When is the Glamsterdam Ethereum Upgrade Happening?
Core developers currently target the second half of 2026 for mainnet activation. More specifically, many discussions point toward a Q3 or Q4 2026 window.
However, Ethereum prioritises correctness and multi-client stability over fixed calendar dates.
Furthermore, the upgrade remains in the devnet testing phase as teams refine specifications and align client implementations.
Meanwhile, public testnets such as Sepolia and Hoodi will activate before any mainnet deployment.
As a result, the exact date will firm up only after successful testnet runs. Nevertheless, the broad second-half 2026 timeframe remains the clearest guidance available today.
Do I Need to Do Anything With My ETH for the Glamsterdam Upgrade?
Regular ETH holders need to take no action whatsoever. Official guidance from ethereum.org and client teams stresses this point repeatedly. Therefore, your balances, addresses, and private keys remain completely unaffected.
Moreover, anyone claiming that you must “upgrade,” “migrate,” or “convert” your ETH is almost certainly running a scam. In contrast, the protocol change occurs at the network level and requires zero user intervention for ordinary accounts.
Thus, the safest approach involves simply holding your ETH and ignoring unsolicited upgrade instructions.
Ultimately, staying informed protects users far more effectively than any reactive steps.

What Are the Main Features / EIPs Included in Glamsterdam?
Two headliner proposals define Glamsterdam. First, EIP-7732 introduces Enshrined Proposer-Builder Separation, often called ePBS.
Secondly, EIP-7928 adds Block-Level Access Lists that enable more efficient validation.
In addition, the upgrade package includes several supporting EIPs focused on gas accounting, contract size limits, and state-related costs.
Furthermore, these changes work together to support a higher sustainable gas limit.
As a result, the combined set of improvements targets both block-construction efficiency and parallel transaction handling.
Therefore, Glamsterdam delivers structural upgrades rather than isolated tweaks.
Will Glamsterdam Lower Gas Fees or Make Transactions Cheaper On Ethereum?
Certain gas-repricing elements aim to reduce the cost of simple transfers and improve fee predictability.
As a result, standard ETH transfers may become noticeably cheaper under typical network conditions.
However, overall fees still depend on demand, blob usage, and Layer-2 activity.
Moreover, higher capacity can ease congestion during peak periods, which often translates into lower average costs.
In contrast, periods of heavy demand may still produce elevated fees regardless of protocol improvements.
Therefore, users should expect better efficiency rather than permanently low fees in every scenario.
Ultimately, the upgrade improves the fee environment without eliminating market-driven price discovery.

How Will Glamsterdam Affect Validators and Node Operators?
Validators and node operators must update both their consensus-layer and execution-layer clients before activation.
Furthermore, the introduction of ePBS changes how blocks are built and validated, so operators need compatible software.
In addition, some proposals under discussion aim to shorten exit queues and improve the staking experience.
Meanwhile, client teams continue testing these changes on devnets to ensure smooth transitions.
As a result, proactive operators who follow official client releases will experience minimal disruption.
Consequently, staying current with client software remains the primary responsibility for anyone running infrastructure.
Will Glamsterdam Increase Ethereum’s Scalability, Gas Limit, or TPS?
Yes, Glamsterdam specifically targets higher L1 capacity. Developers designed the combination of ePBS and Block-Level Access Lists to support a significantly higher gas limit, with discussions frequently referencing a path toward 200 million.
Moreover, parallel validation of non-conflicting transactions reduces the time required to process blocks.
Therefore, the network gains headroom for greater throughput under realistic workloads.
In addition, the longer data-propagation window created by ePBS further supports larger blocks and more blob capacity for Layer-2 networks.
As a result, Glamsterdam advances Ethereum’s scaling objectives on both the base layer and the broader rollup ecosystem.
How Does ePBS Change MEV and Block Building?
Enshrined Proposer-Builder Separation moves the separation of roles directly into the protocol.
Previously, the network relied on external relays such as those used with MEV-Boost. Consequently, ePBS reduces dependence on trusted third parties.
Furthermore, the change expands the time available for data propagation and aims to lower extractable MEV.
In addition, it strengthens censorship resistance by removing a potential centralisation point in the block-production pipeline.
Therefore, many researchers view ePBS as one of the most meaningful structural improvements since the transition to proof-of-stake.
Ultimately, the upgrade reshapes how value flows between proposers and builders.
What Comes After the Ethereum Glamsterdam Upgrade?
Ethereum’s roadmap continues beyond Glamsterdam. Developers already discuss subsequent upgrades, including work targeted under names such as Hegotá.
Moreover, longer-term priorities include further scaling, improved privacy features, and post-quantum cryptography preparations.
In addition, the community continues refining the “Lean Ethereum” vision that emphasises protocol simplicity and security.
Therefore, Glamsterdam functions as one important step rather than a final destination.
As a result, observers should expect a steady sequence of focused upgrades rather than a single transformative event. Thus, the network’s evolution remains ongoing and iterative.

Is Glamsterdam the Biggest Ethereum Upgrade Since The Merge?
Many core developers and observers describe Glamsterdam as the most significant protocol change since The Merge in 2022. The reason lies in its structural impact on block production and validation.
Furthermore, the combination of enshrined proposer-builder separation and parallel execution capabilities addresses foundational bottlenecks.
In contrast, earlier upgrades often delivered more incremental improvements. Therefore, Glamsterdam stands out for the depth of its architectural changes.
Ultimately, its success will determine how effectively Ethereum continues scaling while preserving decentralisation and security.
Ethereum’s upgrade path reflects a deliberate, multi-year effort to improve capacity, efficiency, and resilience.
Glamsterdam occupies a central place in that progression for 2026. Investors, developers, and users who understand its goals and limitations can better evaluate both the opportunities and the realistic timelines ahead.
