What’s on the Ethereum Roadmap: Glamsterdam, Hegota and Beyond
Ethereum has been evolving through a steady cadence of upgrades rather than one big “Ethereum 2.0” flip. Each change arrives as a coordinated hard fork: a bundle of protocol improvements that all activate at the same block. Together, these upgrades target the same core goals: higher throughput, lower transaction costs, better user experience, and a network that remains easy to verify and operate over the long term.
Since the Merge in September 2022, the focus has shifted decisively toward scaling and usability, while still preserving Ethereum’s neutrality and security. Developers are informally targeting roughly two major upgrades per year, provided research and testing are mature enough.
Below is how the roadmap fits together today: the rollup‑centric scaling strategy, the six major “eras” of Ethereum’s evolution, what has already shipped, and what upgrades like Glamsterdam and Hegota are aiming to deliver.

Ethereum’s Rollup‑Focused Scaling Strategy
Instead of trying to cram all activity directly onto the base layer, Ethereum is pursuing a rollup‑centric roadmap:
– Base layer (Layer 1) focuses on security, decentralization, and data availability.
– Rollups (Layer 2) handle most user transactions and computation, periodically posting compressed data back to Ethereum.
This approach has several consequences:
– Scalability comes from L2s, not L1 block size. Ethereum is avoiding massive blocks that would make running a node prohibitively expensive.
– Cheaper transactions via data compression. Rollups batch thousands of transactions into compact proofs or data blobs, then settle to Ethereum.
– Protocol upgrades are tuned for rollups. Many recent and upcoming changes are specifically aimed at making life cheaper and more efficient for rollups rather than end‑users directly.
Upgrades like EIP‑4844 (proto‑danksharding) in the Dencun hard fork are examples of this thinking: they introduce a new, cheaper data space specifically designed for rollups, which translates into lower fees for users transacting on L2.

The Six Phases of the Ethereum Roadmap
Ethereum’s long‑term roadmap is often described as six overlapping themes rather than a strict linear sequence:
1. The Merge
– Transition from proof‑of‑work to proof‑of‑stake.
– Drastically reduced energy usage and set the stage for future optimizations.
2. The Surge
– Scaling the network through rollups and data sharding concepts.
– Aims for tens of thousands of transactions per second across L2s by improving data availability.
3. The Scourge
– Addressing centralization and censorship risks, especially around MEV (maximal extractable value).
– Seeks more neutral, predictable transaction inclusion.
4. The Verge
– Introducing new data structures like Verkle trees to reduce node storage requirements.
– Makes verifying Ethereum much lighter and faster.
5. The Purge
– Cleaning up protocol complexity and historical baggage.
– Reducing node hardware requirements by pruning old data and simplifying rules.
6. The Splurge
– Miscellaneous improvements and “fun stuff” that don’t fit neatly into the other buckets.
– Includes experiments and quality‑of‑life upgrades for both users and developers.
These phases are not strictly sequential; work on several of them happens in parallel. For example, Dencun contributed to the Surge, while upcoming changes around state management tie into both the Verge and the Purge.

Key Ethereum Upgrades Since 2022
The Merge (September 2022)
The Merge joined the original Ethereum execution layer with a new proof‑of‑stake consensus layer:
– Miners and energy‑intensive proof‑of‑work were replaced by validators staking ETH.
– Block production became more predictable, and the network’s energy consumption dropped by orders of magnitude.
– This did not directly increase throughput or lower fees, but it was a prerequisite for nearly everything on the current roadmap.
Shapella (Shanghai/Capella) – April 2023
Shapella was the first major upgrade after the Merge and delivered a crucial missing feature:
– Validator withdrawals: Staked ETH and accumulated rewards could finally be withdrawn or partially unstaked.
– Improved the economic flexibility of staking and made it easier for both individuals and institutions to join as validators.
– Included several smaller execution‑layer optimizations to smart contract behavior and gas accounting.
Dencun (Cancun/Deneb) – March 2024
Dencun is widely regarded as the first big step into the Surge era:
– EIP‑4844 (proto‑danksharding):
– Introduced “blob” storage – a new, temporary data space cheaper than traditional call data.
– Designed for rollups to post transaction data efficiently, significantly lowering L2 transaction fees.
– Various improvements to consensus and execution coordination, making the network more efficient and better prepared for future data‑sharding style upgrades.
The impact of Dencun is primarily visible on rollups: users on major L2s can see noticeably lower gas costs, while the Ethereum base layer remains conservative in block size and complexity.

What Ethereum’s Upgrades Are Trying to Achieve
Across all phases and hard forks, the objectives are consistent:
– Scalability without sacrificing decentralization
Ethereum aims to support massive global usage while keeping it feasible for ordinary users to run their own full or verifying nodes.
– Persistent security and neutrality
The protocol is designed to minimize trusted parties, avoid censorship, and stay robust against economic and technical attacks.
– Better user and developer experience
Lower fees, faster confirmations, safer wallets, and simpler building blocks for applications and L2s.
– Sustainable node operation
Through pruning, better data structures, and streamlined protocol rules, Ethereum wants to avoid a future where only big data centers can run nodes.

Pectra, Glamsterdam, Hegota: The Next Waves
With Dencun live, attention is shifting to the upgrades informally grouped under names like Pectra, Glamsterdam, and Hegota. These are shorthand labels for multi‑fork roadmaps rather than single features.
Pectra (Prague/Electra) – The Near‑Term Focus
Pectra is generally understood as the next major hard fork pair (execution and consensus) and is expected to emphasize:
– Wallet UX improvements such as account abstraction‑related features that make smart contract wallets more powerful and easier to use.
– Validator operations refinements to streamline how validators manage keys, stakes, and responsibilities.
– Additional EIPs that improve the developer experience and fine‑tune gas costs or opcodes.
While specifics evolve as research matures, Pectra is about smoothing the rough edges exposed by earlier upgrades and preparing the system for more radical changes that follow.
Glamsterdam – Toward Lighter Nodes and Stronger Data Structures
Glamsterdam is commonly associated with longer‑term upgrades aimed at major structural changes to Ethereum’s state:
– Verkle trees adoption (The Verge):
– Replacing Merkle Patricia trees with Verkle trees can drastically reduce node storage and improve state proof sizes.
– This would allow light clients to verify state with minimal data, enhancing decentralization.
– State size management:
– Mechanisms to control the ever‑growing amount of on‑chain state, so running a full node does not become prohibitively heavy.
– This may include changes in how contracts store data and how long old state must be retained.
Glamsterdam, therefore, ties directly into the Verge and Purge themes, targeting a future where verifying Ethereum is possible even on modest hardware.
Hegota – Single‑Slot Finality and Consensus Refinements
Hegota is often discussed in the context of ambitious consensus‑layer changes, especially around finality:
– Single‑slot finality (SSF):
– Today, Ethereum finality takes several epochs; SSF would aim to finalize blocks within a single slot, significantly reducing the time to “irreversible” settlements.
– This would improve user confidence and reduce the window for certain types of reorganization attacks.
– Refining staking and validator design:
– Adjusting incentives and architecture so the validator set can remain large and decentralized, while still supporting faster finality and more complex consensus logic.
– Further MEV and censorship‑resistance improvements (The Scourge):
– Continued evolution of block building and relay mechanisms to reduce centralization risks in block production and transaction ordering.
Hegota ambitions are technically demanding and will likely require extensive research, testing, and incremental introduction. They sit at the intersection of performance, security, and decentralization.

How All These Phases Interconnect
While the roadmap is broken into memorable names, the changes reinforce one another:
– Rollup scaling (Surge) relies on affordable data availability, which Dencun began and further sharding‑style advancements will extend.
– Light client improvements (Verge) make it practical for more users and devices to directly verify Ethereum, helping offset any centralization pressure from scaling.
– Protocol simplification (Purge) reduces maintenance overhead and node costs, making upgrades like SSF more manageable.
– Neutrality and MEV work (Scourge) ensures that as Ethereum becomes faster and more widely used, it does not become controlled by a small set of block builders or infrastructure providers.
– Misc upgrades (Splurge) continue to polish usability and fill in gaps that remain after the main milestones.
The names Glamsterdam and Hegota capture clusters of these concerns: Glamsterdam around state and data structures; Hegota around consensus speed and robustness.

What This Means for Users
For everyday users and DeFi participants, the roadmap should translate into a few practical outcomes:
– Cheaper transactions – mainly on L2
Most fee reductions will occur on rollups as the base layer makes their data cheaper. Using L2s will remain the economical way to interact with Ethereum.
– Faster, more reliable confirmations
As finality improves and L2 bridges become more sophisticated, users can expect faster settlement guarantees and smoother cross‑chain transfers.
– Safer, smarter wallets
Account abstraction and related enhancements will allow wallets to support features like social recovery, batched transactions, and more flexible security policies without sacrificing decentralization.
– More options to participate in staking
Adjustments to staking design and validator requirements should broaden access while maintaining network health.
—
What This Means for Developers and Rollup Teams
For builders, especially those working on rollups and protocols, the roadmap offers both opportunities and constraints:
– Design for a rollup‑first world
New dApps are increasingly expected to live on L2s by default. Smart contract patterns, tooling, and UX flows need to reflect this multi‑layer environment.
– Prepare for shifting gas and data models
Features like blobs, state expiry mechanisms, and Verkle trees will change how storage, calldata, and long‑term data retention are priced and managed.
– Embrace lighter clients and modular infrastructure
As the network moves toward better light‑client support, there will be new ways to build applications that verify Ethereum without running full nodes.
– Plan for gradual but constant change
With a target of frequent, non‑disruptive upgrades, application developers should design systems that can tolerate evolving assumptions about gas costs, data availability, and consensus nuances.

Risks, Trade‑offs, and Open Questions
The roadmap is ambitious, and each step comes with trade‑offs:
– Complexity vs. usability
More powerful features for rollups and wallets can make the protocol harder to reason about and implement. Simplifying where possible (the Purge) is critical.
– Decentralization vs. performance
Single‑slot finality and faster consensus typically require tighter coordination across validators. The challenge is to gain speed without narrowing who can realistically participate.
– Economic stability vs. experimentation
Changes in fee markets, staking economics, or MEV mitigation can shift incentives for users, validators, and builders. Careful testing and phased rollouts are essential.
– Long‑term state management
Deciding how much historical data must be retained and at what cost is not just a technical issue but a philosophical one about what it means to be a public ledger.
These questions shape how quickly changes like Glamsterdam and Hegota can safely be deployed.

Beyond Hegota: The Endgame Vision
Looking past currently named upgrades, the long‑term vision for Ethereum is an ecosystem where:
– Most user activity occurs on an array of specialized rollups.
– The base layer is lean, secure, and highly decentralized, primarily serving as a settlement and data availability engine.
– Finality is quick enough for mainstream financial use cases without sacrificing trustlessness.
– Running a verifying node is possible on consumer‑grade hardware, and light clients are ubiquitous across devices.
– Protocol rules are stable and compact enough that further changes can be gradual and conservative.
Glamsterdam and Hegota are stepping stones toward that endgame: a globally scalable, credibly neutral infrastructure layer underpinning both financial systems and a wide range of decentralized applications.
