Ethereum’s 2026 Upgrade Roadmap, Explained Like a City Plan: Glamsterdam, Hegota, and the Quiet Work of Staying Decentralized

Ethereum is entering a very “unsexy” phase of maturity—and that’s a compliment. Instead of chasing the loudest narrative, the 2026 roadmap is built around two planned upgrades—Glamsterdam in the first half of 2026 and Hegota later in the year—designed to improve scalability, reduce cost pressure, strengthen censorship resistance, and move privacy forward. The goal is not a single moonshot; it’s dependable progress delivered in smaller, steadier steps.

If you want a simple way to think about it, imagine Ethereum as a massive city. People come here to trade, send value, run apps, and sign digital agreements. As the city grows, traffic gets worse, warehouses fill up with old records, and some roads become chokepoints. A well-run city doesn’t wait for a collapse to rebuild everything. It upgrades lanes, redesigns intersections, and clears storage—continuously. That is what Ethereum is trying to do in 2026: keep the city expanding without turning it into a centralized megacorp that can be switched off.

1) The 2026 Plan in One Sentence: More Capacity, Less Friction, Fewer Chokepoints

At a high level, Glamsterdam is meant to help Ethereum handle more activity more efficiently—less “single-lane traffic,” more “multi-lane throughput,” and less dependence on specialized intermediaries in the block-building pipeline. Reports describe it as an upgrade where two headline changes—Block Access Lists and enshrined Proposer-Builder Separation—could materially improve how blocks are produced and how transactions are processed.

Hegota, by contrast, is framed as the “long-game” upgrade: addressing the accumulation of old data and strengthening properties that matter when the world gets adversarial—censorship resistance and privacy. Importantly, multiple sources note that the exact scope of both upgrades is still being finalized, which is normal for Ethereum’s process: names and timing can be agreed on before every technical detail is locked in.

• Timing (expected): Glamsterdam in the first half of 2026; Hegota later in 2026.

• Theme: biannual cadence—smaller, regular upgrades instead of rare, oversized “everything forks.”

• North star: scale without turning decentralization into a slogan.

2) Glamsterdam, Explained Simply: Turning One-Lane Traffic Into a Coordinated Multi-Lane System

Most blockchains “feel fast” because they run with fewer constraints, fewer participants, or more centralized coordination. Ethereum’s challenge is different: it aims to scale while staying credibly neutral—meaning no single operator should be able to rewrite rules, block users, or quietly privilege insiders. Glamsterdam’s design direction reflects this: improve throughput by making transaction processing more parallelizable and by smoothing the block production pipeline so the network doesn’t depend so heavily on external coordination layers.

Cointelegraph describes Glamsterdam as bringing “perfect parallel processing” and discusses substantial gas-limit increases as part of the 2026 scaling effort. That language can sound abstract, so here’s the city analogy: instead of forcing every car to go through one long line at one toll booth, the city pre-plans which cars can safely go into which lanes, then opens multiple lanes at once. The key is coordination—done in a way that doesn’t require trusting a single traffic cop.

• What users might feel: less congestion pressure, smoother execution during busy periods, and a network that can absorb higher demand without fees spiking as easily.

• What engineers care about: reducing bottlenecks that come from “everything must be processed strictly in order,” even when tasks don’t conflict.

• What decentralization advocates watch: whether the new system reduces dependence on specialized infrastructure that only a few players can run.

3) The Glamsterdam Feature That Sounds Boring but Changes Everything: Block Access Lists

Block Access Lists (often referenced as EIP-7928 in coverage) are one of those upgrades that won’t make a great marketing poster, but can meaningfully change the network’s efficiency. The intuition is straightforward: if a block can include a map of which pieces of state each transaction touches, then clients can safely execute non-conflicting transactions in parallel rather than serially. That’s the difference between “one cashier serving everyone” and “multiple cashiers working at once because you already know which items belong to which lane.”

Cointelegraph’s explanation emphasizes that this approach helps overcome a major client bottleneck: repeated sequential disk reads and strictly ordered execution, which can cap throughput even when hardware has multiple cores available. If implemented well, it’s a pragmatic scaling step—raising real capacity without requiring Ethereum to abandon its conservative security posture.

• Upside: better multi-core utilization and more predictable performance under load.

• Hidden cost: more complexity in how blocks communicate “what changed,” which raises the bar for client correctness.

• Practical takeaway: scaling isn’t just “bigger blocks”—it’s smarter execution that doesn’t punish honest nodes.

4) Glamsterdam’s Other Headliner: ePBS and the Quiet Battle Over Chokepoints

The second big Glamsterdam theme is enshrined Proposer-Builder Separation (ePBS, often referenced as EIP-7732 in coverage). This is partly about performance, but it’s also about governance reality. Today, much of Ethereum’s block building relies on an external ecosystem (MEV-Boost and relays) that helps coordinate block construction—useful, but also a potential centralization pressure point. Cointelegraph reports that MEV-Boost handles a very large share of blocks and that ePBS would integrate proposer-builder separation into the protocol rather than leaving it as an “out-of-protocol” dependency.

In the city analogy, this is like moving a critical traffic-routing system from a private contractor’s proprietary control room into a transparent public utility with checks and balances. The goal isn’t to eliminate markets or competition; it’s to make sure the system doesn’t require trusting a small set of intermediaries to keep the city moving.

• Decentralization benefit: fewer external chokepoints and less reliance on specialized relays.

• Censorship-resistance benefit: fewer places where transactions can be systematically excluded.

• Scaling side effect: coverage notes ePBS can create more “time budget” for validation workflows and future proof-oriented designs.

5) Hegota, Explained Simply: Cleaning the Warehouses and Hardening the City

If Glamsterdam is about traffic, Hegota is about storage and resilience. Over time, networks accumulate “stuff”: old data, historical traces, and state growth that makes running a node heavier. A chain can survive with this baggage for a while—but the long-term cost is subtle centralization. If the system becomes too heavy, only well-funded operators can run full infrastructure. And if only a few operators can run it, decentralization becomes fragile in practice.

Bankless reports that Ethereum developers selected “Hegota” as the name for the post-Glamsterdam upgrade and highlights that the scope is still forming, with potential focus areas including state and history expiry mechanisms and execution-layer optimizations. Cointelegraph’s coverage of the late-2026 upgrade direction also points toward privacy and improved censorship resistance as key themes. Put together, the story is not “Ethereum adds a shiny new feature.” It’s “Ethereum keeps itself sustainable and harder to interfere with.”

• Warehouse cleanup: reduce or manage old data accumulation so the system stays lightweight enough for diverse operators.

• Hardening upgrades: push the network toward stronger privacy and fewer censorship vectors.

• Long-term result: Ethereum remains a city where many can run the infrastructure, not a city run by a few utilities.

6) Why Ethereum Chooses “Steady Upgrades” Instead of a Big Rewrite

A common misconception is that ambitious systems should “just rebuild” when scaling gets hard. In public infrastructure, big rewrites can create new risks: massive coordination burdens, unknown attack surfaces, and brittle transitions where everyone must upgrade perfectly. Ethereum’s approach—regular, smaller upgrades—reflects a different philosophy: reduce risk by making progress in units that can be tested, debated, and deployed with clearer boundaries.

That doesn’t make upgrades safe by default. It makes them governable. The more Ethereum becomes a base layer for broad economic activity, the more it must behave like infrastructure that people can rely on—where changes are predictable, well-audited, and communicated early enough for wallets, exchanges, and application teams to prepare. Glamsterdam and Hegota are not just technical names. They’re part of a process that treats coordination as a first-class engineering constraint.

• The real innovation: building a machine for continuous improvement without continuous chaos.

• The real risk: upgrade fatigue, complexity creep, and unintended consequences across clients and apps.

• The real signal to watch: whether Ethereum can ship upgrades on schedule without sacrificing stability.

7) What Users and Builders Should Watch in 2026

“Faster and cheaper” is the headline everyone wants—but Ethereum upgrades often deliver benefits unevenly at first. Some improvements show up as smoother performance under load, others as better node economics, and others as structural readiness for future scaling (including privacy-oriented pathways). The most practical expectation is not a single moment where Ethereum becomes “solved.” It’s incremental gains that accumulate—especially when paired with rollups and better application design.

For builders, the critical work is preparation: testing against new execution behaviors, understanding how gas repricing or access-list mechanics might affect contract assumptions, and making sure user flows don’t break during network transitions. For users, the key is recognizing that the “city upgrades” are designed so you don’t have to think about them—your apps should simply feel more reliable over time.

• For users: watch network reliability during busy windows, and whether peak-fee spikes become less dramatic.

• For builders: follow client readiness and testnet timelines, and audit for edge-case execution assumptions.

• For the ecosystem: watch whether decentralization improves in practice (more diverse infrastructure), not just in slogans.

Conclusion

Ethereum’s 2026 roadmap is best understood as city planning for decades, not months. Glamsterdam is the traffic redesign—more coordinated throughput, fewer execution bottlenecks, and a block-production pipeline that depends less on external intermediaries. Hegota is the warehouse cleanup and hardening—addressing data accumulation, strengthening censorship resistance, and moving privacy forward so the system remains usable and difficult to control.

And that’s the deeper lesson: Ethereum isn’t trying to win by being the loudest chain. It’s trying to win by being the chain that stays credible, resilient, and usable at scale—even as the world becomes more complex. In infrastructure, the most important work is often the work you barely notice. That is what 2026 is shaping up to be.

Frequently Asked Questions

Are Glamsterdam and Hegota “confirmed,” or can plans change?

Coverage indicates developers have aligned on the names and general timing, but multiple sources note that the exact scope of each upgrade is still being finalized. Ethereum’s roadmap evolves through ongoing developer calls, testing, and community review.

Will Glamsterdam instantly make Ethereum fees “cheap”?

Not necessarily instantly, and not in every situation. Improvements like parallel processing and pipeline changes can increase capacity and smooth congestion, but fees are also influenced by demand, application design, and the broader rollup ecosystem.

Why does Ethereum care so much about “state” and “history” bloat?

Because long-term data accumulation can make running nodes more expensive, which can reduce the number of independent operators. Managing state and history is part of keeping Ethereum decentralized in practice, not just in principle.

Does “censorship resistance” mean no one can ever block transactions?

It means the system is designed to minimize chokepoints where exclusion can be enforced and to make censorship harder to sustain. It’s a property that improves through architecture, incentives, and diversity of infrastructure.
