According to Gate market data, as of March 12, 2026, Ethereum (ETH) is trading at $2,030.65, with a 24-hour trading volume of $400.84M and a market capitalization of $250.03B, representing a market share of 9.87%. Against this backdrop, Ethereum’s core development team is accelerating preparations for its next major network upgrade—Glamsterdam. Based on the Ethereum Foundation’s 2026 protocol priority update, Glamsterdam is expected to launch on mainnet in the first half of 2026. Its core features include not only encapsulated proposer-builder separation at the consensus layer, but also, for the first time, a clear technical roadmap for integrating zkEVM verification clients and post-quantum security. This article provides a comprehensive breakdown of the upgrade across four dimensions: technical evolution, data models, market controversies, and future scenarios.
Technical Positioning of Glamsterdam
Glamsterdam is a pivotal hard fork upgrade in Ethereum’s 2026 roadmap. Following the Pectra and Fusaka upgrades in 2025, the network has already implemented an independent fork mechanism for Blob parameters and increased the Gas Limit from 30 million to 60 million. Building on these changes, Glamsterdam aims to address three core challenges: centralization risks at the consensus layer, distorted resource pricing in the execution layer, and long-term security threats posed by quantum computing.
According to official disclosures from the Ethereum Foundation, protocol work in 2026 will focus on three tracks: Scale (integrating L1 execution with Blob expansion), Improve UX (emphasizing native account abstraction and cross-chain interoperability), and Harden the L1 (enhancing security, censorship resistance, and network resilience). As the main upgrade for the first half of the year, Glamsterdam will deliver several headline features from these tracks, including:
- Encapsulated proposer-builder separation: Embeds builder interaction rules directly into the consensus layer, eliminating reliance on external relay networks.
- Block-level access lists: Enables parallel transaction verification within blocks, improving block space utilization.
- Initial implementation of multidimensional Gas: Separates state creation costs from execution and call data costs, enabling differentiated resource pricing.
- zkEVM verification client prototype: Allows some validators to act as provers, paving the way for broader adoption in 2027.
- Post-quantum security readiness: Advances verification and migration paths for quantum-resistant signature schemes.
Technical Evolution from Fusaka to Glamsterdam
Ethereum’s technical roadmap follows a snowballing iterative logic. In 2025, the Pectra and Fusaka upgrades were activated in succession, laying the groundwork for Glamsterdam. Fusaka’s most significant achievement was the introduction of an independent fork mechanism for Blob parameters, allowing Ethereum to increase Blob counts without waiting for a full hard fork. Currently, each block targets 14 Blobs, with a maximum of 21, expanding L2 data availability by 2.3 times compared to pre-Fusaka levels.
Against this backdrop, preparations for Glamsterdam began in earnest in January 2026. The following table summarizes key milestones:
| Milestone | Upgrade/Event | Core Content |
|---|---|---|
| May 2025 | Pectra Upgrade | Introduced multiple execution layer optimizations, paving the way for scaling |
| December 2025 | Fusaka Upgrade | Activated PeerDAS, enabling independent Blob parameter forks |
| January 2026 | First BPO Fork | Increased Blob count to target 14, max 21 |
| February 2026 | Ethereum Foundation releases 2026 priority update | Clarified three tracks, confirmed Glamsterdam for first half of year |
| First half of 2026 | Glamsterdam Upgrade (expected) | Activates ePBS, BALs, multidimensional Gas EIPs, and zkEVM verification client prototype |
| Second half of 2026 | Hegotá Upgrade (planned) | Expected to introduce FOCIL and other headline censorship-resistant features |
Technical Overhaul: Multidimensional Gas and zkEVM
The most fundamental changes in the Glamsterdam upgrade center on the introduction of multidimensional Gas and the advancement of zkEVM verification clients.
Multidimensional Gas will be implemented in phases, starting with the separation of state creation costs from execution and call data costs in Glamsterdam. Currently, Ethereum’s single-dimensional Gas model prices all computation, storage, and bandwidth resources uniformly. This simplified approach can distort resource pricing in complex transactions. For example, large-scale state writes consume much more disk space than simple transfers, yet Gas pricing barely reflects this difference. After the multidimensional Gas reform:
- State creation Gas: Will be measured separately and not counted toward the current transaction Gas limit (about 16 million).
- Execution and call data Gas: Will retain the existing pricing model, though parameters may be adjusted with broader repricing.
This separation, using a reservoir mechanism, addresses EVM subcall issues and more accurately reflects true resource consumption, discouraging abuse of state space. From a data structure perspective, this marks Ethereum’s transition from rough resource management to a refined economic model.
On the zkEVM front, the Ethereum Foundation has committed to a phased rollout: in 2026, clients will be able to participate as provers; in 2027, a larger portion of the network will be encouraged to run zkEVM and focus on formal verification; eventually, the protocol will shift to a "5 out of 3" mandatory proof mechanism, where all nodes (except those needing indexing) will rely on zkEVM proofs. This means Glamsterdam will move zkEVM from academic papers to testnet and potentially mainnet prototypes, laying the foundation for significantly reduced validator hardware requirements.
Dissecting Public Opinion: L2 Value Capture and Quantum Security Debates
Debate around the Glamsterdam upgrade has shifted from technical feasibility to questions of economic fairness and security prioritization.
L2 Value Capture Controversy
This shift stems from a pronounced imbalance between L2 networks’ economic contributions and their rewards. Take Coinbase’s Base chain as an example: after the Dencun upgrade, Blob data costs for L2s publishing to L1 plummeted, allowing Base to reap substantial sequencer revenue while paying minimal settlement fees to Ethereum mainnet. Data shows Base earned $3.7M in a given month, but paid only $0.305M in settlement fees to Ethereum—less than 10%. This security arbitrage has sparked strong dissatisfaction among some community members, who argue that L2s extract Ethereum’s liquidity value without making proportional contributions to network security.
There are two main viewpoints:
- Ethereum as a public goods substrate: Voices like David Hoffman of Bankless argue that the Ethereum Foundation allows L2s to freely extract sequencer profits while enjoying mainnet security, diluting ETH’s value capture. They advocate for some form of fee or mandatory ETH staking for L2 sequencers.
- L2 prosperity as an ecosystem win: Others believe that low L2 fees (now often below $0.1) are essential for Ethereum’s mass adoption. Vitalik himself has repeatedly emphasized that L2 development solves mainnet congestion and high Gas fees, and shouldn’t be seen as a threat.
Urgency of Quantum Security Debate
Within the community, opinions diverge on the priority of post-quantum security. Some developers believe quantum computing’s threat to elliptic curve cryptography is still 10–15 years away, and investing resources in protocol-level changes now could detract from more urgent scaling efforts. However, the Ethereum Foundation’s Harden the L1 track treats post-quantum security as an insurance policy, advocating proposals like EIP-7702 to promote native account abstraction and provide a cleaner migration path from ECDSA to quantum-resistant signature schemes. While this forward-looking strategy increases short-term development complexity, it helps avoid the risk of emergency hard forks in the future.
Narrative Reality Check: Technical Idealism vs. Economic Realities
The core narrative of the Glamsterdam upgrade is to make Ethereum a better decentralized substrate, but its evolution faces multiple challenges.
First, ePBS is seen as a key solution to MEV centralization risks. The current PBS (proposer-builder separation) relies on external relay networks, which are vulnerable to censorship and single points of failure. ePBS embeds builder interaction rules directly into the consensus layer, theoretically eliminating reliance on trusted relays. However, the complexity of this design has slowed development compared to BALs, and it remains in early devnet stages. Whether it can launch with Glamsterdam as planned is still uncertain.
Second, the fairness narrative of multidimensional Gas must withstand empirical scrutiny. While separate pricing is theoretically more rational, it also increases block construction complexity. Validators must manage multiple resource pools simultaneously, which could reduce block utilization or complicate transaction packaging strategies. Some developers in the community worry that multidimensional Gas may become a new moat for centralized builders, as only professional builders can efficiently optimize block profits under multi-resource constraints.
Third, discussions about L2 economics often overlook key facts. Data supporting the "L2 vampire" theory typically focuses on major profit-driven L2s (like Base and Arbitrum), ignoring attempts by L2s such as Taiko to return sequencing rights to L1. These L2s are more tightly integrated with Ethereum mainnet, but their market share remains small and insufficient to shift the overall narrative.
Industry Impact Analysis: Three Layers of Game Theory after Glamsterdam
If Glamsterdam proceeds as planned, its industry impact will unfold across three levels:
L1 Validators and Staking Economy
The implementation of ePBS will change validator reward structures. Currently, validators passively receive blocks relayed by external networks; in the future, they’ll actively participate in builder market dynamics. This could intensify free-riding behavior among small validators or create new decentralized builder pools. Combined with the Ethereum Foundation’s plan to raise the Gas Limit to 100M or higher, validators may see increased transaction fee income, partially offsetting the erosion of mainnet fees by L2 growth.
L2 Competitive Landscape Differentiation
Multidimensional Gas and increased Blob parameters will further lower L2 data publication costs. At the same time, calls for fair contribution may prompt leading L2s to proactively adjust their economic models. In the short term, profit-driven L2s will maintain high margins; in the medium to long term, sequencer-based L2s aligned with L1 may gain more ecosystem support. The L2 market will shift from a simple fee war to an alignment war.
Application Layer Development Paradigm Shift
Rising costs for state creation and access will directly impact deployment strategies for high-frequency state read/write DApps (such as blockchain games and social protocols). Developers may prefer to migrate state storage to L2s or alternative solutions, while L1 gradually returns to its role as a settlement and core asset custody layer. This aligns with Ethereum’s long-term vision as digital "concrete."
Scenario Evolution Forecast
Based on current information, the aftermath of the Glamsterdam upgrade may play out in three scenarios:
Scenario 1: Smooth Transition
ePBS developer networks stabilize in Q2 2026, with 10–12 out of 17 candidate EIPs selected for activation. After initial multidimensional Gas implementation, the network runs smoothly and state storage growth is effectively controlled. L2 fees remain low, and Ethereum mainnet achieves moderate revenue growth through Blob fees and higher Gas Limits. ETH’s market share stabilizes between 9% and 11%.
Scenario 2: Technical Delays
Major consensus vulnerabilities are discovered in ePBS during testnet, requiring redesign of certain modules and delaying its integration until Hegotá or later upgrades. Glamsterdam becomes a lightweight upgrade focused mainly on BALs and Gas fee adjustments. The market questions Ethereum’s roadmap execution ability, resulting in short-term negative sentiment.
Scenario 3: Intensified Economic Game
After Glamsterdam goes live, L2 economic imbalances persist, and calls to levy fees on L2s evolve into formal proposals. These proposals face strong resistance from leading L2s and their ecosystem projects, sparking fierce debates over governance legitimacy. Some L2 communities discuss migrating to alternative L1s, causing temporary centrifugal forces within the Ethereum ecosystem.
Conclusion
The Glamsterdam upgrade marks Ethereum’s first major technical milestone in 2026. It goes beyond simple performance improvements, aiming for systemic reconstruction across consensus mechanisms, economic models, and security architecture. The initial rollout of zkEVM verification clients and proactive post-quantum security planning demonstrate the core development team’s decade-long technical foresight. However, the complexity of the solutions, shifting community interests, and external competition all add layers of uncertainty to this upgrade. For industry participants, understanding the technical details and potential impacts of Glamsterdam is essential to seizing structural opportunities in the crypto market in 2026.
