Ethereum in 2026: How Glamsterdam and Heze‑Bogota Could Redefine the Network
After a pivotal year in 2025, marked by the Pectra upgrade in May and Fusaka in December, Ethereum is preparing for an even more ambitious leap in 2026. The next phase centers on two major milestones: the Glamsterdam fork, focused primarily on performance and scalability, and the Heze‑Bogota fork, aimed at enhancing privacy, censorship resistance, and decentralization.
Together, these upgrades are designed to push Ethereum closer to its long‑term vision: a fast, permissionless, and resilient base layer capable of supporting mass adoption without sacrificing security or core values.

From Pectra and Fusaka to the Next Era
Pectra and Fusaka laid the groundwork by improving throughput and making it cheaper and more efficient to run and use Ethereum, especially for layer‑2 (L2) networks. These upgrades:
– Increased data availability for rollups.
– Helped lower node operating costs.
– Improved scalability without compromising on security.
However, those developments mainly optimized Ethereum’s existing architecture. The 2026 roadmap goes further by reorganizing how transactions are processed and how data is validated on a fundamental level.

Glamsterdam Fork: A New Engine for Ethereum’s Throughput
The Glamsterdam fork, expected around mid‑2026, is being positioned as a major scaling milestone. At its core, Glamsterdam aims to change how Ethereum handles transactions, pushing the network from incremental improvements to a more radical performance shift.
Key goals of Glamsterdam include:
– Parallel transaction processing
Instead of processing transactions one after another, Ethereum will begin to handle multiple transactions at the same time. This parallelization allows the network to deal with more activity in a shorter period, significantly increasing effective throughput.
– A substantial gas limit increase
Today, Ethereum operates with a gas limit around 60 million per block. Glamsterdam proposes a jump to roughly 200 million, with the possibility of that ceiling being raised further by the end of 2026. A higher gas limit means more operations can be executed in each block, allowing more user activity without every spike in demand causing severe congestion.
– Reworking validator responsibilities
Under the current design, validators must inspect and validate full transaction data. After Glamsterdam, much of this validation burden is expected to shift toward zero‑knowledge (ZK) proofs. Validators will verify cryptographic proofs rather than all underlying data directly, which can significantly reduce the computational workload and improve scalability.
—
From 21 TPS to a New Performance Frontier
Ethereum’s base layer currently processes roughly 21 transactions per second (TPS) on average. With Glamsterdam’s parallel execution and higher gas capacity, projections suggest the network could ultimately reach around 10,000 TPS under favorable conditions.
This would not only alleviate bottlenecks but also:
– Reduce the frequency of fee spikes during busy periods.
– Make the base layer more accommodating for rollups and other scaling solutions.
– Improve user experience by lowering confirmation times for many types of activity.
Importantly, these improvements are meant to complement layer‑2 scaling, not replace it. Even at tens of thousands of TPS, the base layer is designed to act as a secure settlement layer, while rollups and other L2s handle a large share of everyday transactions at even higher speeds and lower costs.

Why Zero‑Knowledge Proofs Matter for Validators
A central piece of Glamsterdam is the transition toward using zero‑knowledge proofs in validator workflows. Instead of re‑executing every transaction, validators will increasingly verify compact cryptographic proofs that attest to the correctness of state transitions.
This shift offers several benefits:
– Efficiency: Less computation per block means validators can process more data with the same hardware.
– Decentralization: Lower hardware requirements make it easier for more participants to run full nodes or validators, mitigating centralization risks.
– Security: ZK proofs provide strong mathematical guarantees; if the proof checks out, validators can be confident that the underlying transactions followed the rules.
For users and developers, this could mean a more responsive network that remains accessible to home stakers and small operators, rather than concentrating power in large, well‑funded infrastructure providers.

Heze‑Bogota Fork: Bringing Privacy and Censorship Resistance to the Forefront
If Glamsterdam is Ethereum’s performance overhaul, the late‑2026 Heze‑Bogota fork is its privacy and resilience enhancement. The upgrade is designed to confront a growing concern: as blockchains become more integrated into mainstream finance and global regulation, the risk of censorship and transaction filtering increases.
Heze‑Bogota targets three interconnected goals:
1. Enhanced privacy
By integrating more advanced cryptographic techniques, including ZK‑based mechanisms, Ethereum intends to give users stronger privacy guarantees. While not turning the network into a fully anonymous system, the changes are expected to make it harder to link specific addresses and activity patterns, especially for sensitive use cases.
2. Stronger censorship resistance
The fork is aimed at reducing reliance on centralized infrastructure or single points of control that could block or filter transactions. Architectural and protocol‑level adjustments are expected to make it more difficult for any entity—whether a government, corporation, or service provider—to prevent valid transactions from being included in blocks.
3. Deeper decentralization
By reducing dependence on a few dominant infrastructure providers and distributing responsibilities more widely, Heze‑Bogota should push Ethereum further toward its original ethos: an open network no one controls and anyone can use, regardless of location, identity, or local regulations.
—
A More Open and Permissionless Ethereum
As Ethereum adoption expands—for payments, decentralized finance, NFTs, gaming, identity, and institutional applications—the question of who can access the network becomes crucial. Heze‑Bogota is meant to reinforce the principle that Ethereum must remain permissionless by default.
Post‑upgrade, the network is expected to:
– Make it more difficult to enforce blacklists or transaction filters at the protocol level.
– Provide tools that allow developers to build applications with stronger privacy guarantees for their users.
– Create a better environment for innovation in regions with restrictive financial systems.
For individuals, this could translate into greater confidence that their transactions will not be arbitrarily blocked. For developers, it opens the door to building applications that balance regulatory compliance at the application layer with strong guarantees of neutrality at the protocol layer.

Combined Impact: Speed, Privacy, and Long‑Term Sustainability
Taken together, Glamsterdam and Heze‑Bogota aim to position Ethereum as:
– Faster, through parallel execution and larger gas limits.
– More efficient, thanks to ZK‑based validation and reduced validator overhead.
– More private, via improved cryptographic tooling for sensitive transactions.
– More censorship‑resistant, by minimizing reliance on centralized actors.
– More decentralized, with a lower barrier for running validating infrastructure.
These qualities are increasingly critical as the blockchain space becomes more competitive. With rival smart contract platforms emphasizing speed or low fees, Ethereum’s strategy is to combine performance with robust security, neutrality, and a rich existing ecosystem.

What This Means for Layer‑2s and the Broader Ecosystem
A common question is whether these 2026 upgrades will make L2s obsolete. In practice, the opposite is more likely: L2s stand to benefit directly.
– Higher base‑layer throughput lets rollups publish more data per block, potentially lowering their own fees.
– Faster confirmation times on L1 improve finality for L2 transactions, making cross‑chain bridges and rollup withdrawals smoother.
– Enhanced privacy and censorship resistance at the base layer cascade up to applications and L2s that inherit Ethereum’s security.
Developers building rollups, decentralized exchanges, lending platforms, or on‑chain games may find that the 2026 upgrades give them more room to innovate while still relying on Ethereum as a secure settlement and data‑availability layer.
—
Validator and Node Operator Perspective
For validators and node operators, 2026 is likely to be a transition year:
– Hardware requirements may change: Some aspects of validation will become lighter thanks to ZK proofs, but parallel processing and higher gas limits could demand more capable infrastructure in other respects.
– Client software will evolve: Node and validator clients will need to support new execution models and proof verification, making upgrades and testing critical.
– Incentive structures could shift: As throughput grows, transaction volume and fee dynamics might change, affecting rewards and the economics of staking.
Participants will need to stay informed, update their setups, and perhaps diversify infrastructure strategies to stay aligned with the new environment.

ETH Price Outlook Heading into 2026
On the market side, these upgrade discussions are unfolding as ETH trades below the 3,000‑dollar mark. Recent price action has seen ETH consolidating in the 2,800–2,900 range, with 3,000 acting as a strong short‑term resistance level.
One long‑term trend indicator suggests:
– A potentially bullish finish to 2025.
– A chance for ETH to close the year above 3,000.
– A possible trading range between roughly 3,200 and 3,400 at the beginning of 2026.
– A subsequent correction or retracement phase around mid‑January.
However, this constructive scenario remains sensitive to broader market conditions. Persistent bearish pressure across the crypto sector could delay or weaken any anticipated upside, even if Ethereum’s fundamental outlook improves with the upcoming upgrades.

Risks, Uncertainties, and Implementation Challenges
While the 2026 roadmap is ambitious, it is not without risks:
– Technical complexity: Parallel execution and ZK‑based validation are non‑trivial to implement. Bugs or unforeseen interactions could surface during testnet phases or even after deployment if not carefully managed.
– Ecosystem readiness: Wallets, dapps, exchanges, and infrastructure providers will all need to adapt. Any lag in adoption could temporarily fragment the ecosystem or create user experience issues.
– Regulatory tensions: Stronger privacy and censorship resistance may draw additional regulatory scrutiny. Balancing innovation with compliance pressure at the application and business layers will be a challenge.
These factors mean that timelines could shift, features might be adjusted, and the exact impact on fees, throughput, and user experience will only become fully clear once upgrades are live and under real‑world load.

How Users and Developers Can Prepare
For everyday users:
– Stay updated on the expected timelines for Glamsterdam and Heze‑Bogota.
– Use wallets and tools that commit to keeping pace with protocol changes.
– Be cautious around upgrade windows, as network conditions can temporarily fluctuate.
For developers:
– Begin reviewing new protocol features and tooling as soon as they’re available in testnets.
– Test smart contracts, rollups, and infrastructure against the updated execution and validation models.
– Consider how enhanced privacy and censorship resistance can be integrated into app design in a compliant and user‑friendly way.
Preparing early can help both users and builders benefit from the upgrades from day one, rather than scrambling to catch up after changes go live.
