The first half of 2026 will see Ethereum’s most anticipated protocol-level upgrade since the Merge—Glamsterdam. Unlike previous upgrades such as Dencun and Pectra, which focused on data availability and scalability, Glamsterdam directly addresses two long-standing structural challenges for the Ethereum network: the centralization risks of MEV in block construction, and the execution layer’s serial processing bottleneck. More importantly, Glamsterdam is not an isolated event. Together with the Hegotá upgrade expected at the end of the year, it forms Ethereum’s dual-track roadmap for 2026: "performance scaling + state minimization." This marks Ethereum’s transition into an era of "predictable engineering delivery" for protocol evolution.
Core Objectives of the Ethereum Glamsterdam Upgrade
Glamsterdam is a protocol hard fork scheduled for the first half of 2026, following the major milestones of Pectra (May 2025) and Fusaka (December 2025). According to the Ethereum Foundation’s latest progress report on April 10, 2026, implementation is advancing steadily, with the testnet launch planned for the week of April 18, 2026—a crucial step to reduce full upgrade risks.
This upgrade centers on two primary goals: First, it will overhaul the MEV mechanism with ePBS (Enshrined Proposer-Builder Separation), reducing reliance on centralized relays and enhancing both transparency and censorship resistance in block construction. Second, by introducing block-level access lists and a new gas repricing mechanism, Glamsterdam will significantly boost L1 execution efficiency, pushing the network’s theoretical transaction throughput toward the 10,000 TPS range.
Technical Progression: From the Merge to Glamsterdam
Ethereum’s protocol upgrades have shifted from "annual single upgrades" to a new cadence of "twice-yearly hard forks." The successful rollouts of Pectra and Fusaka in 2025 validated this engineering pace. Glamsterdam is the first major upgrade of this new cycle, with Hegotá—featuring FOCIL (EIP-7805) at the consensus layer—scheduled for the second half of the year.
Within this context, Glamsterdam’s role is clear: Pectra, via EIP-7251, raised the maximum effective validator balance from 32 ETH to 2,048 ETH, optimizing staking efficiency. Fusaka improved data availability sampling through PeerDAS. Glamsterdam now goes deeper into the protocol’s core, directly reforming the underlying logic of block building and transaction execution. These upgrades form a progressive improvement chain—staking efficiency → data availability → execution and MEV—rather than a set of isolated features.
How ePBS Delivers Around 70% MEV Reduction
Structural Flaws in the Current MEV Architecture
Currently, MEV on Ethereum operates primarily through the MEV-Boost and relay system: Searchers identify arbitrage and liquidation opportunities, Builders compete to construct blocks, submit bids through relays, and validators (Proposers) select the highest bid and sign off.
While this "off-chain auction" model improves efficiency, it brings three major risks:
- Relay Centralization: A handful of relay nodes have become quasi-infrastructure in block construction, controlling critical block flow and creating a single point of censorship risk.
- Lack of Transparency: The bidding and block construction logic among builders is not protocol-supervised, making it difficult for market participants to verify the authenticity and fairness of bids.
- Misaligned Interests Between Builders and Validators: Validators rely on external relays for optimal block bids, but relays are not trust-minimized at the protocol layer, leading to information asymmetry and potential value extraction.
Protocol-Level Overhaul with ePBS
The Glamsterdam upgrade introduces ePBS via EIP-7732, embedding Proposer-Builder Separation directly into Ethereum’s consensus layer. The core workflow is as follows:
| Step | Role | Action |
|---|---|---|
| 1 | Builder | Constructs candidate blocks and submits bids |
| 2 | Proposer | Selects the block with the highest bid |
| 3 | Network | Verifies and finalizes the block |
With ePBS, the block bidding and selection process is automated at the protocol level, eliminating the need for external relays as intermediaries. Validators can select optimal blocks without relying on centralized infrastructure, while the rules for block construction become more open and transparent.
The Quantitative Logic Behind "~70% MEV Reduction"
Research shows that protocol-level PBS can reduce MEV extraction by about 70%. This figure is based on three structural impacts of ePBS on the current MEV market:
First, it eliminates the information rent of relays. In the current system, some relay operators capture hidden profits by monopolizing block flow information. ePBS makes the bidding process open and protocolized, squeezing out these information rents.
Second, it increases transparency and competition efficiency. ePBS moves block bid competition from an off-chain "black box" to an open protocol market, reducing inefficient value leakage caused by information asymmetry.
Third, it weakens vertical integration incentives between builders and validators. ePBS simplifies validator operations and lowers the competitive edge of vertically integrated staking-plus-building entities, allowing more independent validators to participate in MEV revenue sharing with lower barriers.
However, it’s important to note: ePBS is not an "MEV eliminator." MEV is an inherent part of Ethereum’s blockspace value. ePBS makes value extraction more transparent and fair, not obsolete. Academic studies also reveal that while ePBS redistributes responsibilities between builders and proposers, it may significantly increase profit and content concentration—the Gini coefficient for profits rises from 0.1749 under standard PoS to 0.8358 with ePBS, meaning a few highly efficient builders could capture most of the value through MEV-driven bidding.
Quantifying Gas Repricing and Execution Efficiency Gains
Glamsterdam’s parallel processing architecture, based on EIP-7928, redefines gas and state access mechanisms. By using block-level access lists to pre-read transaction dependencies, it allocates non-conflicting transactions to different CPU cores for parallel execution—a fundamental shift from "single-lane serial" to "multi-lane parallel" processing.
At the same time, the gas limit is set to increase from 60 million to 200 million, pushing theoretical TPS from around 1,000 to nearly 10,000. For gas repricing, EIP-7904 recalibrates fees based on actual CPU, storage, and bandwidth usage. After adjustment, gas fees could drop by about 78.6%—a Uniswap transaction that currently costs $3–8 could fall below $1 post-upgrade.
This improvement aligns with Ethereum’s trend of historically low gas fees. In January 2026, the average gas fee dropped to about $0.15, with some swaps costing as little as $0.04 and a seven-day moving average of nearly 2.5 million transactions. Glamsterdam’s gas repricing could further compress user transaction costs at these low fee levels.
Institutional Valuations and Market Divergence
Market views on the Glamsterdam upgrade and Ethereum’s 2026 outlook are sharply divided. These differences can be analyzed across institutional research, market pricing, and community discussions.
Institutional Pricing Frameworks
Citi has set a short-term price target of $3,175, while Standard Chartered forecasts $7,500 by year-end, framing the market’s bullish case. This divergence reflects differing institutional views on the upgrade’s catalytic effect: the conservative camp sees the upgrade as a "defensive improvement" that maintains Ethereum’s competitiveness rather than driving a valuation leap, while the optimists believe the dual upgrades of Glamsterdam and Hegotá will trigger ETH’s re-rating.
As of April 16, 2026, Gate market data shows the ETH price at $2,357.99, up 1.71% in 24 hours, with a market cap of $271.24 billion and a 10.58% market share. There’s a significant gap between the current price and institutional targets, and the market is in a "wait-and-see" mode ahead of the upgrade.
Divergent Signals in Market Pricing
Prediction market Polymarket currently assigns a 56% probability that ETH will hit $1,500 at some point in 2026—a figure that has risen with broader speculative position unwinding. Meanwhile, technical analysis shows ETH has reclaimed its short-term moving averages (MA7, MA14, MA30), with market sentiment gradually recovering from the "mini crypto winter" of Q1.
These conflicting signals—downside risk in prediction markets versus technical momentum—reflect the market’s complex psychology toward the Glamsterdam upgrade: recognizing its technical significance but remaining cautious about macro liquidity and institutional risk appetite.
Community and Developer Discussion Highlights
Developer discussions around ePBS are focused on the "free option" problem: builders might withdraw bids after submission, theoretically slowing network response during periods of high stress. The ePBS-devnet-1 launched on March 31, 2026, is currently testing local block construction, with more complex builder market stress tests planned for future testnets.
Additionally, Vitalik Buterin has emphasized that Glamsterdam will introduce a multidimensional gas framework, separating "state creation" costs from "execution and call data" costs, and using a "reservoir" mechanism to address gas metering for EVM subcalls. This lays the groundwork for further gas market refinement and scaling.
Industry Impact: Dual Repricing of Ethereum Network Structure and ETH Value
Reshaping the MEV Value Chain
Glamsterdam’s impact on the MEV value chain will be profound. Current relay-dependent infrastructure—such as major MEV-Boost relay operators like Flashbots—will face structural changes to their business models. With ePBS moving block bidding to the protocol layer, relays will lose their status as "essential intermediaries," while competition in the builder market will intensify.
Independent validators will be the main beneficiaries of this upgrade. Under ePBS, validators can receive builder bids and select optimal blocks directly, without relying on external relays, streamlining operations and lowering entry barriers. For DeFi protocols, a more transparent MEV market means improved predictability in transaction execution, with previous uncertainties from MEV strategies like sandwich attacks potentially alleviated.
Potential Impacts on ETH Market Structure
Glamsterdam’s effect on ETH’s market structure can be viewed from two angles. On the supply side, gas repricing and parallel processing won’t directly alter ETH’s inflation/deflation dynamics—EIP-1559’s burn mechanism remains driven by network activity—but lower costs could spur on-chain activity, indirectly increasing burn rates. As of mid-April 2026, staked ETH totals about 35 million, nearly 30% of the circulating supply (about 120.7 million), with institutional holdings steadily rising.
On the demand side, the upgrade lowers the mainnet’s usage barrier, potentially attracting DeFi apps and high-frequency use cases that had migrated to Layer 2s or competing chains due to high gas fees. Ethereum mainnet is also solidifying its role as a "settlement and security layer," with Layer 2s handling execution and scaling, and L1 providing finality and security—clarifying the layered architecture.
Ethereum vs. Solana: The 2026 Competitive Landscape
The Glamsterdam upgrade coincides with Solana’s most aggressive technical upgrade cycle. In March 2026, Solana’s Alpenglow consensus upgrade reduced block finality from about 12 seconds to 150 milliseconds, with the full Firedancer validator client (already testing at over 1 million TPS) slated for year-end release.
| Dimension | Ethereum (Post-Glamsterdam) | Solana (2026 Roadmap) |
|---|---|---|
| Theoretical TPS | ~10,000 (progressive target) | 1 million+ in testing |
| Fees | Expected to reach "cent-level" | $0.001–0.017 |
| Finality | ~12 seconds (no major change) | 100–150 ms |
| Ecosystem Role | Settlement layer + security base | High-frequency trading + consumer apps |
| Decentralization | Broad node distribution | Performance/decentralization trade-off |
These two blockchains are pursuing distinct competitive strategies: Ethereum is reinforcing its position as an institutional-grade settlement layer, boosting security and efficiency with ePBS and parallel processing. Solana continues to push performance boundaries, aiming to be the "decentralized Nasdaq" for high-frequency and consumer applications. While Glamsterdam won’t eliminate Ethereum’s raw throughput gap, it will significantly narrow the competitive disadvantage in transaction costs and processing efficiency, while maintaining Ethereum’s lead in decentralization and ecosystem depth.
Multi-Scenario Evolution Forecast
The actual impact of the Glamsterdam upgrade will depend on the interplay of multiple factors. Below are possible development paths under different scenarios.
Baseline Scenario: Technical Delivery, Mild Market Response
Glamsterdam launches successfully in the first half of 2026 as planned. ePBS effectively reduces MEV centralization risks, gas fees drop by the projected 70%–80%, and parallel processing begins to boost network throughput. The market gradually prices in the upgrade, ETH recovers steadily with macro support, and L1 activity rebounds as costs fall. In this scenario, Ethereum’s competitive stance shifts from "defensive" to "balanced," though structural performance gaps will require Hegotá and subsequent upgrades to fully close.
Bullish Scenario: Dual Upgrades Trigger Re-Rating
Both Glamsterdam and Hegotá are successfully deployed, creating a "performance scaling + state minimization" resonance. Gas fees stabilize at "cent-level," L1 usage costs approach Solana-like user experiences, and on-chain activity surges. Institutional capital flows into ETH spot ETFs accelerate, and the market re-evaluates Ethereum’s long-term valuation framework. In this scenario, Ethereum could shift from a "scaling narrative" to a "usability and institutionalization narrative," resetting its price discovery mechanism upward.
Cautious Scenario: Technical Hurdles, Centralization Risks Shift
Testnet trials reveal edge cases with ePBS, such as the "free option" issue, delaying or phasing the upgrade rollout. MEV centralization risk shifts from relays to builders—a few efficient builders monopolize block construction, driving the Gini coefficient sharply higher and sparking community debate over "new centralization." Market expectations for the upgrade partially fade, and ETH remains under macro pressure. In this case, the core goals—improving MEV market transparency and fairness—may require further governance measures.
Conclusion
The Glamsterdam upgrade marks a pivotal transformation in Ethereum’s protocol evolution—from external scaling focused on data availability and throughput, to intrinsic optimization centered on block construction fairness and execution efficiency. By embedding PBS at the protocol layer, ePBS directly tackles relay centralization, aiming for a 70% reduction in MEV extraction. Gas repricing and parallel processing target a theoretical 78.6% fee reduction and 10,000 TPS, opening new possibilities for Ethereum mainnet usability.
However, the true value of the upgrade will be realized only as expectations turn into reality. While ePBS reduces relay centralization, it may shift concentration risks to builders. The theoretical scale of gas fee reductions must be validated in live network conditions. Achieving 10,000 TPS will be a gradual process driven by both Glamsterdam and Hegotá, not the result of a single upgrade. For Ethereum ecosystem participants, understanding these "known unknowns" is more valuable than simply tracking headline metrics.
Glamsterdam is not the endpoint of Ethereum’s evolution, but the starting engine for its dual upgrades in 2026. As the market focuses on the upgrade’s rollout and its interaction with macro conditions, Ethereum’s role as the backbone of global crypto assets is evolving from a "scaling-only narrative" to a story of usability, fairness, and security. Whether this evolution translates into sustained ETH value discovery will depend on the resonance of technical delivery, ecosystem adaptation, and macro liquidity.
