Ethereum Foundation Protocol Cluster Outlines 2029 Quantum-Resistant Roadmap and Hegotá Upgrade Priorities

Following months of integration and ecosystem-wide alignment following the appointment of three new cluster coordinators in May, the Ethereum Foundation (EF) Protocol cluster has published its definitive long-term priorities, governing commitments through 2029, and the scoping parameters for upcoming network hard forks. With the Glamsterdam upgrade approaching mainnet deployment, the Protocol cluster has officially entered the scoping season for Hegotá, laying out a rigorous path designed to secure Ethereum against future quantum computing threats.

The updated strategy is the result of an intensive months-long consultation process that utilized dozens of proposal templates, multiple cluster-wide working sessions, and rigorous retrospectives on the Glamsterdam upgrade. Approximately 60 core researchers and engineers participated in shaping a unified roadmap, evaluating 62 separate Ethereum Improvement Proposals (EIPs) to forge a critical path starting with the Hegotá scoping process. Alongside this overarching vision, the EF Protocol cluster has released a companion evaluation detailing tier lists and specific justifications for every candidate EIP considered for Hegotá.

The North Star: Quantum Resistance by 2029

The primary guiding objective for the EF Protocol cluster is ambitious and absolute: achieving quantum resistance across all three layers of the Ethereum Layer 1 protocol—execution, consensus, and data—by December 2029. This self-imposed deadline purposefully mirrors independent post-quantum cryptography migration timelines established by major technology leaders such as Google, Cloudflare, and Microsoft.

While precise estimates for "Q-day"—the theoretical moment when quantum computers become powerful enough to break standard public-key cryptography—remain uncertain and potentially distant, the Protocol cluster has chosen a deliberately aggressive planning assumption. By targeting complete readiness by 2030, the network aims to send an unequivocal signal regarding its long-term viability across decades and centuries. Although Ethereum has historically avoided all-in infrastructural bets, the unpredictable nature of quantum advancements necessitates a proactive stance. This timeline will remain non-negotiable at least until January 2027, at which point external cryptographic experts will assist in re-evaluating global quantum progress.

The Plan: Two Cadences and Multi-Fork Strategy

Executing post-quantum readiness across the protocol requires navigating an aggressive fork schedule. With client teams slated to begin Hegotá implementation in late 2024, maintaining a linear trajectory from Glamsterdam in December 2026 to a final post-quantum milestone five hard forks later demands an average cadence of just 7.2 months per fork. Recognizing the risks of such a tight schedule, recent updates to the community "Strawmap" introduced a minimum viable post-quantum (MV-PQ) contingency milestone known as J*.

This contingency milestone aims to establish a post-quantum public-key registry, a post-quantum consensus heartbeat, lean data availability (DA) sampling, and lean SPHINCS execution transactions by December 2029 on a more manageable 12-month cadence. While MV-PQ will serve as a temporary safeguard providing reduced cryptographic guarantees during a transitional period, full economic finality and comprehensive post-quantum security across all layers remain the ultimate December 2029 goal. Because fork ordering past J remains flexible, the research teams are treating Hegotá, I, and J* as a single cohesive delivery sequence, recognizing that success will require unprecedented parallel coordination among client developers, cryptographers, security reviewers, and grant recipients across the global ecosystem.

Five Multi-Fork Research Arcs

To balance immediate upgrades with long-horizon developments, the Protocol cluster organizes its ongoing engineering and research efforts into five multi-fork arcs: fast finality, post-quantum, privacy, state management, and zkEVM.

The fast finality arc aims to reduce Ethereum’s transaction finality window from minutes to seconds by decoupling finality from block production, with prototypes targeted for the I* fork. The post-quantum arc spans all execution, consensus, and data layers, utilizing cryptographic agility on the execution layer via native account abstraction while applying battle-tested, unified cryptographic updates to the consensus layer.

Concurrently, the privacy arc focuses on establishing native, trustless, and censorship-resistant private transactions starting with Hegotá, eventually scaling to post-quantum privacy and encrypted mempools. The state arc addresses protocol bloat through trie migrations and decentralized state access beginning heavily in I*. Finally, the zkEVM arc progressively shifts execution proofs from optional features to mandatory validations, allowing validators to verify succinct zero-knowledge proofs rather than re-executing entire blocks, while driving forward formal verification tooling that benefits the entire protocol.

Setting Priorities and Managing the Maturity Pipeline

The core governing imperative of the Protocol cluster remains focused on concentrating resources on what only Protocol-level changes can achieve while fulfilling the core mandate of the network. Following Glamsterdam, the internal priority ladder has shifted from immediate hazard management and near-term upgrades toward accelerating the critical path items required for minimum viable post-quantum readiness, with formal verification established as a cross-cutting tool supporting all research arcs.

Ideas must move systematically through an established maturity pipeline—transitioning from open research to formal EIPs, software prototypes, developer nets, and eventually through PFI, CFI, and SFI signaling stages among core developers before reaching mainnet integration. Each step is designed to minimize uncertainty and provide empirical implementation evidence rather than relying solely on theoretical consensus.

Hegotá as the First Testing Ground

Hegotá itself represents the immediate proving ground for this renewed strategic framework. Rather than acting as the ultimate post-quantum upgrade, Hegotá is the critical fork that determines whether subsequent post-quantum milestones can be delivered on schedule. Its confirmed headliners include EIP-7805 for Fork-Choice Enforced Inclusion Lists (FOCIL) on the consensus layer and EIP-8141 for Frame Transactions on the execution layer, which together form the core engineering lift of the upgrade.

In alignment with the Ethereum Foundation Mandate, Hegotá preserves the core properties of censorship resistance, privacy, and security. FOCIL and associated validator profiles directly bolster censorship resistance by requiring builders to include specific transactions. Privacy enhancements such as Keyed Nonces and Recent Roots remove structural barriers for privacy applications on Layer 1. Simultaneously, security enhancements like Frame Transactions, withdrawal credential retirements, and transaction assertions fortify account validation, laying the groundwork for eventual retirement of legacy cryptographic assumptions without disrupting the strict testing surface required to keep the network stable.

The EF Protocol cluster has invited community engagement and further questions regarding the Hegotá EIP tier lists and roadmap priorities, scheduling a dedicated community AMA session on Reddit to address developer and user inquiries.
