Ethereum’s Glamsterdam fork will introduce some of the most aggressive base-layer upgrades the network has attempted, targeting major gains in throughput, decentralization, and long-term sustainability. Scheduled for Q2/Q3 2026, the fork aims to be the capstone of Ethereum’s “Surge” era, shifting focus from pure data capacity to deep architectural changes in how blocks are built and executed.
While The Merge transitioned Ethereum to proof-of-stake, Glamsterdam could prove equally transformative by fundamentally restructuring how the network processes transactions. The implications: theoretical throughput toward 10,000 TPS by end of 2026, dramatically reduced MEV extraction, and pathway to 100,000+ TPS across Layer 2 ecosystems.
The Parallel Processing Revolution
Historically, Ethereum has operated as a single-threaded state machine, meaning transactions are processed one after another in linear fashion. Glamsterdam begins the transition toward multi-core processing, where independent transactions—simple token transfers or swaps on isolated DEXes—can execute simultaneously.
Core teams plan to ratchet the gas limit from around 60 million to roughly 200 million once the new execution model proves stable. This 3.3x increase opens space for far more complex and frequent activity at Layer 1, positioning Ethereum as viable competitor to centralized settlement networks.
The technical implementation involves overhaul of execution so nodes can handle multiple independent chunks of state simultaneously, cutting bottlenecks that currently force transactions through mostly linear pipelines. Developers believe that by optimizing how the Virtual Machine interacts with hardware, the network can maintain decentralized nature without sacrificing speed required for modern high-frequency trading and real-world asset tokenization.
Enshrined Proposer-Builder Separation (ePBS)
Glamsterdam carries political and economic edge through ePBS, codified in EIP-7732 as one of the fork’s “headliner” upgrades. By moving proposer-builder split into protocol itself, Ethereum reduces dependence on external MEV relays and private marketplaces that concentrate power in few infrastructure players.
EIP-7732 formalizes Proposer-Builder Separation directly into Ethereum protocol. The goal: create more trustless and censorship-resistant method for block production by removing dependency on external, trusted relays. By enshrining PBS, the network aims to reduce centralization pressures from MEV, improve security, and create more competitive and transparent market for block builders.
According to analysis, ePBS will mitigate MEV by 70% through proposer-builder separation, creating fairer transaction ordering. This matters for institutional adoption—firms won’t deploy capital on infrastructure where miners can front-run their trades with impunity.
Verkle Trees and Stateless Clients
Plans for Glamsterdam suggest using Verkle trees and improving gas and storage costs to reduce state bloat, helping regular operators continue running full nodes as on-chain activity increases.
A primary focus is transition from Merkle trees to Verkle trees. This change is anticipated to enhance how Ethereum stores data and validates transactions, paving way for greater scalability and efficiency. Verkle trees are critical component of Ethereum’s “The Verge” phase, aimed at making state access more efficient and enabling stateless block verification.
Verkle Trees enable stateless clients, drastically reducing storage burden on node operators by up to 90%. This shift not only lowers barrier to entry for running full nodes but also enhances censorship resistance by decentralizing infrastructure.
Currently, running an Ethereum full node requires storing hundreds of gigabytes of historical data. Post-Verkle implementation, nodes can verify the entire blockchain without requiring participants to store massive historical datasets. This ensures running a full node remains accessible to individual participants rather than just massive data centers.
Block-Level Access Lists and Gas Optimization
Block-Level Access Lists (EIP-7928) pre-declare accounts and smart contracts a block will interact with. This optimization reduces computational overhead for nodes, enabling faster execution and laying groundwork for parallel transaction processing.
Glamsterdam will focus on making Ethereum faster and cheaper to use, particularly for complex applications like Layer-2 rollups and zero-knowledge (ZK) technology. For developers, Glamsterdam’s changes promise more predictable execution, better parallelization, and base layer tuned for rollup-centric designs rather than chain that merely stores data blobs.
The Six-Second Block Time Proposal
Ethereum core developer Barnabé Monnot proposed reducing block time from current 12 seconds to 6 seconds. This would effectively double Ethereum’s transaction throughput at Layer 1 by allowing blocks to be produced twice as frequently.
Combined with parallel processing, increased gas limits, and Verkle tree optimizations, six-second blocks could transform Ethereum’s user experience. Transactions would confirm faster, DeFi protocols would feel more responsive, and Layer 2 rollups would benefit from more frequent settlement windows.
Critics note faster blocks increase network bandwidth requirements and could slightly reduce decentralization by favoring well-connected nodes. But protocol researchers see the fork as bridge between today’s scaling gains and future where stateless clients, ZK-verified blocks, and high-frequency applications can coexist on credibly neutral L1.
The 2026 Timeline and Development Status
The Ethereum core development team officially finalized technical specifications and launch windows for Glamsterdam. This decision marks significant shift toward more predictable, biannual release cycle aimed at providing stability required for institutional-grade financial applications.
In early 2026, one or more public testnets are planned. These testnets are vital for identifying interoperability issues under realistic network conditions and for broader community participation, allowing dApp developers, node operators, and researchers to test applications against new changes.
Following testnet phase, two 30-day windows are allocated for security audits and community bug hunts, a model successfully employed during Fusaka upgrade. This comprehensive testing process is designed to ensure network resilience and gather essential developer feedback before committing to mainnet activation.
Developers plan to finalize Glamsterdam’s complete scope at their January 5 meeting. This meeting will determine which EIPs make final cut and establish precise activation timeline for Q2/Q3 2026.
What Comes After: Hegota in Late 2026
Ethereum core developers confirmed “Hegota” as network’s next major upgrade following Glamsterdam. The name merges Bogota for execution layer and Heze for consensus layer.
Hegota is scheduled for latter half of 2026 and targets long-term challenge of state bloat. The technical highlight is introduction of Verkle Trees—while Glamsterdam lays groundwork, Hegota completes the Verkle tree transition.
The twice-yearly upgrade schedule marks strategic shift for Ethereum development. Previous upgrades bundled large numbers of changes into releases happening roughly once annually. The faster cadence aims to address community criticism about slow protocol development relative to network’s rapid expansion.
What Users Actually Experience
Users may not notice upgrade immediately in interface terms, but combined effects—higher effective throughput, less reliance on opaque MEV infrastructure, healthier node economics—aim to surface as lower fees and more consistent performance during peak demand.
The improvements compound:
- Parallel processing → more transactions per block
- Increased gas limit → larger blocks
- Faster block times → more frequent confirmations
- ePBS → fairer transaction ordering
- Verkle trees → easier node operation
Result: Ethereum that feels faster, costs less, and works more reliably during network congestion. For DeFi users, this means less slippage from MEV, faster trade execution, and lower gas costs. For NFT collectors, faster minting with reduced chance of failed transactions during drops. For developers, more headroom to build complex applications without hitting gas limits.
The Competition Context
Ethereum’s dominance faces challenges from faster Layer 1s like Solana, which processes 3,200 TPS with sub-second finality. Glamsterdam aims to close that gap while maintaining Ethereum’s decentralization advantages.
Glamsterdam is expected to be final major step before “The Surge” portion of Ethereum’s roadmap is considered complete, pushing sustainable throughput toward 100,000+ TPS across Layer 2 ecosystem while maintaining full decentralization.
That’s the key difference: Ethereum isn’t trying to match Solana’s raw speed at Layer 1. It’s building infrastructure where Layer 2 rollups can achieve comparable speed while inheriting Ethereum’s security and decentralization. Glamsterdam provides the foundation enabling this rollup-centric roadmap.
The Bottom Line
Ethereum’s 2026 upgrades mark transformative phase in blockchain’s evolution. By addressing scalability, MEV, and state efficiency, the network is positioning itself as dominant smart contract platform for the next decade.
Glamsterdam won’t generate headlines like The Merge did—there’s no dramatic narrative about eliminating mining or reducing energy consumption. But technically, it might matter more. The Merge changed how Ethereum reaches consensus. Glamsterdam changes how Ethereum processes transactions, which directly impacts every user, every application, and every Layer 2.
If executed successfully, Glamsterdam represents Ethereum delivering on promises made years ago about becoming “world computer.” Not through single breakthrough, but through methodical protocol improvements that compound into fundamental capability expansion.
For investors, developers, and users, the message is clear: 2026 is when Ethereum stops talking about scaling and starts delivering it. Whether that proves sufficient to maintain Ethereum’s dominance against faster competitors remains to be seen. But make no mistake—Glamsterdam is the most consequential Ethereum upgrade since The Merge.
And this time, the improvements might actually change how the network feels to use.
