London, UK – [Current Date] – Ethereum, the world’s leading smart contract platform, is in the midst of a critical development phase, meticulously laying the groundwork for its next two major network upgrades: Glamsterdam and Hegotá. While the rapid succession of previous upgrades like Pectra and Fusaka had fueled optimism for accelerated development cycles, the current "Checkpoint" update from Ethereum’s core development team reveals a more intricate reality. The Glamsterdam upgrade, intended to introduce foundational changes like enshrined Proposer-Builder Separation (ePBS), is proving to be a substantial undertaking, demanding careful and deliberate progress. Simultaneously, the community is already shaping the contours of Hegotá, with a landmark decision to prioritize FOCIL (EIP-7805) and a firm commitment to integrating Account Abstraction.
This periodic high-level update, designed to demystify the complex discussions held during Ethereum’s All Core Developer (ACD) calls, highlights both the challenges and the unwavering determination of the global developer community. The journey towards a more scalable, secure, and user-friendly Ethereum is a marathon, not a sprint, characterized by rigorous technical deliberation and a collaborative spirit.
The Unfolding Narrative: A Chronology of Ethereum’s Development
Ethereum’s evolution is a continuous process of iterative improvements, each upgrade building upon the last to enhance the network’s capabilities. Following the significant "Merge" which transitioned Ethereum to Proof-of-Stake, and subsequent upgrades like Shanghai, Capella, Pectra, and Fusaka, the network is now focusing on addressing core architectural challenges.
Glamsterdam: A Foundational Leap Encumbered by Complexity
The Glamsterdam upgrade (EIP-7773) represents a pivotal moment in Ethereum’s development roadmap, aiming to implement several deep-seated structural changes. While its full list of features can be tracked on Forkcast, the primary focus and, consequently, the main source of its slower-than-anticipated progress, is the implementation of enshrined Proposer-Builder Separation (ePBS).
Understanding ePBS and its Impact:
Proposer-Builder Separation (PBS) is a critical architectural shift designed to mitigate the risks associated with Maximal Extractable Value (MEV). MEV refers to the profit that can be extracted by block producers (validators) through their ability to include, exclude, or reorder transactions within the blocks they produce. Currently, this process happens largely "outside" the core protocol, leading to potential centralization pressures and opaque practices.
Enshrined PBS brings this mechanism "inside" the consensus protocol, fundamentally altering how blocks are constructed. Instead of a single validator both proposing and building a block, ePBS separates these roles:
- Proposer: A validator is selected to propose a block header.
- Builder: Specialized entities (block builders) compete to construct the most profitable block body, submitting bids to the proposer.
The proposer then selects the builder’s block that offers the highest bid, ensuring a more transparent and competitive market for block production. This separation aims to:
- Decentralize MEV: By allowing more participants to build blocks, it reduces the power of any single entity.
- Enhance Censorship Resistance: It makes it harder for proposers to unilaterally censor transactions, as they are decoupled from the block’s internal contents.
- Improve Network Health: By making MEV extraction more explicit and competitive, it can lead to a more efficient and fair distribution of rewards.
The Implementation Challenge:
The original article aptly describes ePBS implementation as "trickier than anticipated." This is because the shift touches virtually every layer of the Ethereum stack. The protocol now needs to reason about "partial blocks" (the header from the proposer, the body from the builder) and manage the complexities of two-party coordination within the consensus mechanism. This involves:

- New State Transitions: Defining how the blockchain state updates when a block is constructed by two distinct parties.
- New Networking Protocols: How proposers and builders communicate securely and efficiently.
- New Economic Incentives: Ensuring fair compensation for both roles while maintaining network security.
- Handling Disagreement and Failure: The protocol must robustly manage scenarios where proposers and builders fail to coordinate or disagree on block content.
Other Glamsterdam Features:
Beyond ePBS, Glamsterdam is set to include other vital enhancements:
- Gas Repricings (EIP-8007 bundle): This involves adjustments to how gas costs are calculated for various operations. The aim is to optimize network resource utilization, prevent spam, and ensure that transaction fees accurately reflect the computational cost to the network. These repricings are often bundled together to streamline implementation and testing. Ecosystem developers have been constructively vocal about the importance of these changes for long-term network efficiency.
- Increase to Maximum Contract Size (EIP-7954): This EIP addresses a current limitation that restricts the complexity and functionality of smart contracts deployed on Ethereum. Increasing the maximum contract size is crucial for enabling more sophisticated decentralized applications (DApps) and fostering innovation within the ecosystem. The strong advocacy from ecosystem developers underscores its practical importance.
- Block-level Access Lists (BALs) (EIP-7928): These represent a fundamental rethinking of how gas and state access work on the execution layer. BALs aim to provide more granular control and predictability over transaction execution, which can lead to more efficient gas usage and improved transaction processing. Development of BALs on dedicated devnets is showing predictable progress, navigating these inherently difficult problems.
Development Progress and Timeline:
The path to Glamsterdam’s mainnet launch involves a series of rigorous testing phases. Developers are currently aiming for the first generalized Glamsterdam devnet in the near future, contingent on the stabilization of the current ePBS devnet. This will be followed by several iterations of devnets, progressively integrating more of the non-headliner features. Only after achieving a stable devnet with all included features will client releases be cut, final security reviews conducted, and testnets launched. The mainnet fork date will only be announced once these testnets are confirmed stable, indicating a cautious and security-first approach.
The initial excitement for a Q2 Glamsterdam launch, spurred by the quick follow-up of Fusaka to Pectra, now appears unlikely. The intricate nature of ePBS and other deep-seated changes necessitates a more extended development and testing period. However, the core developers remain undeterred by the challenges, demonstrating resilience and commitment to delivering a robust upgrade.
Hegotá: Shaping the Future Beyond Glamsterdam
Even as Glamsterdam is under active development, the Ethereum community is already looking ahead to the subsequent upgrade, codenamed Hegotá. The process for selecting its major features has concluded, providing a clear direction for future development.
FOCIL (EIP-7805) as the Consensus Layer Headliner:
Hegotá’s consensus layer headliner will be FOCIL (EIP-7805). While the specifics of FOCIL are not detailed in this update, its selection as a major feature indicates its strategic importance for the long-term health and functionality of Ethereum’s consensus mechanism. Such consensus-layer improvements often focus on aspects like validator efficiency, network security, or further refinements to the Proof-of-Stake model.
Account Abstraction: A Community Priority:
A significant discussion point for Hegotá involved Account Abstraction (AA), a highly anticipated feature that promises to revolutionize user experience on Ethereum. Account Abstraction aims to blur the lines between externally owned accounts (EOAs, controlled by private keys) and smart contract accounts, enabling functionalities typically associated with traditional web accounts. This includes:

- Social Recovery: Allowing trusted friends or family to help recover a lost wallet.
- Batch Transactions: Bundling multiple operations into a single transaction for efficiency and cost savings.
- Customizable Signature Schemes: Using biometric authentication or multi-factor authentication instead of raw private keys.
- Paying Gas in ERC-20 Tokens: Eliminating the need for native ETH for gas fees.
While there was intense debate on the execution layer side regarding a specific proposal, EIP-8141 ("Frame transactions"), a lack of broad consensus on its implementation details led to it being moved to "Considered for Inclusion" (CFI) status as a non-headliner. Crucially, this signifies a placeholder commitment from core developers to work on an Account Abstraction proposal that garners wider support among client developers and involves active community participation. The community’s strong desire for AA remains a driving force, and it is still possible that a refined or alternative AA proposal could be promoted to a headliner status if consensus solidifies.
Quantum Resistance: A Growing Imperative:
Another area of increasing interest for future upgrades is quantum resistance. As quantum computing technology advances, there’s a recognized need to develop cryptographic primitives that can withstand attacks from quantum computers. While no standalone quantum resistance proposal has yet been introduced, its inclusion as part of broader account abstraction packages highlights its growing importance in the long-term security considerations for Ethereum.
Non-Headlining Feature Proposals:
To ensure broad community involvement, the process for proposing non-headlining features for Hegotá began on April 9th. Any interested party can propose an EIP by pulling it into the "Proposed for Inclusion" section of the fork’s meta EIP (EIP-8081). The closing date for these submissions will be announced at least two weeks in advance, providing ample time for community input. The Hegotá Forkcast page remains the definitive source for the most up-to-date information on its process and timeline.
The timeline for Hegotá is inherently linked to Glamsterdam’s progress. A delayed Glamsterdam will naturally push back Hegotá. However, with only a single major headliner chosen for Hegotá, and a clear commitment to address Account Abstraction, it holds the potential to follow Glamsterdam in a relatively shorter timeframe, provided the non-headliner selection and implementation proceed smoothly.
Supporting Data and Community Resources
Gas Limit Expansion: Boosting Network Throughput
A continuous effort within Ethereum development is the ongoing testing of increased gas limits on devnets. The gas limit dictates the maximum amount of computational work (gas) that can be included in a single block, directly influencing the network’s transaction throughput. The current target for the baseline gas limit is 60 million. However, developers are actively testing significantly higher limits to thoroughly understand the implications and necessary optimizations required to safely achieve these capacities. Much of the gas repricing work being implemented in Glamsterdam is foundational to enabling these higher, safer limits, ensuring that increased throughput does not compromise network stability or security. The goal is to allow more transactions per block, enhancing scalability without resorting to sharding.
Empowering Community Participation: The EIP Champion’s Handbook
Recognizing the importance of community involvement in shaping Ethereum’s future, the Protocol Support team has published new resources to assist authors and advocates in championing their feature proposals. The EIP Champions Handbook provides a comprehensive guide for navigating the Ethereum Improvement Proposal (EIP) process, offering insights into seeking stakeholder feedback, refining proposals, and moving them through the various stages of consideration. This initiative aims to democratize the development process, empowering a broader range of contributors to propose and advocate for innovations that can enhance the Ethereum network.
Official Responses and Community Sentiment
The core development calls, comprising All Core Developers (ACD), All Core Developers – Execution (ACDE), and All Core Developers – Consensus (ACDC), serve as the primary forums for these discussions. The linked calls from January 21st to April 9th underscore the continuous, detailed deliberation that goes into each upgrade. These calls are publicly accessible, embodying Ethereum’s commitment to transparency and decentralized governance.
Despite the technical complexities and the slower pace of Glamsterdam, client developers appear remarkably resilient and committed. The challenges are acknowledged, but they do not seem to be particularly disheartened, viewing them as integral parts of advancing a global, decentralized infrastructure.

A significant development in guiding community priorities has been the emergence of the "strawmap." While not an "official Ethereum roadmap," this community-driven guideline, published this year, has reignited enthusiasm for a shared vision that can help inform feature choices during the upgrade process. It serves as a beneficial tool in fostering community agreement on priorities, bridging the gap between technical possibilities and broader ecosystem needs. This informal yet influential roadmap helps align the diverse interests within the Ethereum community, providing a directional compass for future development.
Implications for Ethereum’s Future
The current state of Ethereum’s development, as outlined in this "Checkpoint" update, carries several significant implications for the network’s future:
Timeline Adjustments: The expectation of Glamsterdam launching in Q2 now appears unlikely. The profound nature of ePBS, in particular, requires meticulous implementation and extensive testing to ensure network stability and security. This deliberate pace, while potentially frustrating for some, is a testament to the developers’ commitment to robust and secure upgrades. The decentralized nature of Ethereum means that no single entity can dictate a rushed timeline, prioritizing network integrity over arbitrary deadlines.
Interdependent Upgrades: The direct dependency of Hegotá’s timeline on Glamsterdam’s progress highlights the interconnectedness of Ethereum’s upgrade cycle. Delays in one upgrade inevitably cascade to the next. However, the decision to select a single consensus layer headliner (FOCIL) for Hegotá, coupled with a dedicated commitment to Account Abstraction as a minor feature, could potentially allow Hegotá to follow Glamsterdam in a shorter timeframe than Glamsterdam follows its predecessors, provided the non-headliner process is efficient and an AA proposal gains rapid consensus.
Focus on Foundational Strength: The emphasis on ePBS in Glamsterdam underscores a strategic focus on strengthening Ethereum’s foundational architecture. By addressing MEV and enhancing decentralization at the protocol level, Ethereum is investing in long-term resilience against potential centralization risks and censorship. Similarly, gas repricings and increased gas limits aim to improve the network’s core efficiency and scalability.
User Experience and Innovation: The strong community interest and developer commitment to Account Abstraction for Hegotá signal a clear direction towards significantly improving the user experience on Ethereum. Easier wallet management, enhanced security features, and more flexible transaction options are crucial for mainstream adoption. Furthermore, the increase in maximum contract size in Glamsterdam will unlock new possibilities for DApp developers, fostering innovation within the ecosystem.
Community-Driven Evolution: The success of the "strawmap" and the emphasis on the EIP Champions Handbook reinforce Ethereum’s commitment to a community-driven development model. These tools empower a broader range of stakeholders to contribute to the network’s evolution, ensuring that upgrades reflect the diverse needs and aspirations of its global user base and developer community.
In conclusion, Ethereum is navigating a complex yet exciting phase of its development. The Glamsterdam upgrade, while demanding patience due to its intricate foundational changes, is poised to deliver critical improvements in decentralization and network efficiency. Looking ahead, Hegotá promises significant advancements in consensus layer technology and a long-awaited focus on user experience through Account Abstraction. This continuous, iterative process, driven by a dedicated global community of developers, underscores Ethereum’s unwavering commitment to building a more robust, scalable, and user-centric decentralized future. The journey may be challenging, but the collective resolve to enhance the world’s leading smart contract platform remains stronger than ever.
