The Ethereum Protocol cluster has officially published its highly anticipated tier list for Hegotà¡¡, a pivotal release that meticulously ranks 62 Ethereum Improvement Proposals (EIPs) based on their proposed inclusion and strategic importance. This marks a significant milestone as it represents the first time the entire Protocol cluster, encompassing approximately 60 research and engineering professionals from various teams, has presented a unified view of these critical proposals, moving beyond individual team opinions. The detailed evaluation, which assigns a tier and a concise rationale to each EIP, offers unparalleled clarity on the priorities guiding the Ethereum network’s future development.
This consolidated approach signifies a maturing process within the Ethereum development community, emphasizing collaborative decision-making and transparency. While Geth, a leading execution layer client, will continue to publish its own standalone tier list, its feedback, along with that of all other Protocol cluster members and individual contributors, has been thoroughly integrated into this comprehensive assessment. The underlying priorities that informed these grades are further elaborated in a companion post titled "EF Protocol: Current and Emerging Priorities," providing essential context for the decisions made.
I. The Rigorous Tiering Process: A Collaborative Endeavor
The creation of the Hegotà¡¡ tier list was a multifaceted and rigorous process, designed to capture the collective expertise and diverse perspectives within the Ethereum Protocol cluster. A total of nine distinct teams, alongside several individual domain experts, contributed to the evaluation. Each participant completed contribution templates, resulting in 16 submissions that collectively generated 397 tier grades across the 62 EIPs under consideration. On average, each EIP received 6.4 grades, with the most contentious proposals attracting up to nine distinct evaluations.
Key lessons learned from previous retrospectives, particularly those held during the "Glamsterdam" event, heavily influenced the methodology. These lessons underscored the importance of sizing EIPs by their integration depth, recognizing how complexity compounds, acknowledging that testing surface is a scarce resource, and understanding that champions often underestimate the inherent complexity of proposed changes. To address points of contention and refine the evaluations, the cluster convened several group calls and a dedicated 90-minute working session. A detailed account of the process, including the August 28th procedural post, offers further insights into the meticulous steps taken.
The Scoring Mechanism: A Nuanced Approach to Prioritization
The scoring system employed for the Hegotà¡¡ tier list was designed for nuance and clarity. Each contributor independently assigned a tier to each EIP using a point system: S (4 points), A (3 points), B (2 points), C (1 point), and D/DFI (0 points). The average score was calculated based on the grades cast, with abstentions intentionally excluded from the calculation to avoid penalizing proposals that may not have garnered broad consensus or direct feedback. The "steelman" tier assigned to each EIP in the publication began with these average grades and was subsequently debated and refined EIP-by-EIP during the working sessions, allowing for adjustments in both directions. Crucially, individual per-team grades were not publicly disclosed, maintaining the focus on the collective consensus.
Each tier level signifies distinct delivery expectations for the cluster:
- S Tier: These are considered "headliners" or "must-ship" proposals, indicating a strong consensus for immediate implementation.
- A Tier: Proposals in this tier are strongly recommended for inclusion and are expected to ship, often with minor conditions or clarifications.
- B Tier: These EIPs are on the "bubble." Their inclusion is contingent upon meeting specific, clearly defined requirements that would elevate them to the A tier.
- C Tier: Proposals in this tier face significant concerns and are generally not expected to ship in the current iteration. The notes accompanying these EIPs detail the specific issues that would need to be addressed.
- DFI (Declined/Further Investigation): These EIPs are declined for various reasons, with the accompanying notes outlining the concerns that led to this decision.
The structure of the notes column in the published tier list table is deliberately patterned to provide immediate clarity. For proposals expected to ship (S and A tiers), the notes highlight their merits and strategic importance. For proposals on the bubble (B tier), they specify the precise requirements needed for an upgrade. For proposals below the line (C and DFI tiers), the notes focus solely on the concerns that led to their classification.
II. The Hegotà¡¡ Tier List: A Detailed Breakdown
The full tier list, presented visually for comprehensive understanding, is available on Forkcast. The tables below are meticulously sorted by tier, and then by average score within each tier, offering a clear hierarchical view of the proposed improvements. The grade count, indicating the number of evaluations received for each EIP, is displayed alongside the average score.
Consensus Layer: Strengthening the Network’s Foundation
The consensus layer proposals are crucial for the fundamental operation and security of the Ethereum network. This section of the tier list reveals a focus on enhancing inclusion guarantees, refining staking functionalities, and optimizing network performance.
- EIP-7805 (FOCIL): This EIP is designated as an "S" tier "headliner," unanimously recognized for its critical role in providing users with a direct path to include eligible transactions without relying on centralized builders. Its inclusion is tightly coupled with EIP-8369.

- TBD Tier Proposals: EIP-8368 (CPSB Recalibration for New Gas Limit) and EIP-8372 (Normalized State Gas Limit) are marked "TBD," indicating they are awaiting post-Glamsterdam mainnet data for a final decision on recalibration, normalization, or inaction.
III. Closing Thoughts: A Strategic Vision for Ethereum’s Future
The Hegotà¡¡ tier list represents a significant achievement in transparent and collaborative development for the Ethereum network. Of the 62 proposals evaluated, 2 are designated as "must-ship" (S tier), 15 are expected to ship (A tier), and 28 are declined with clear reasoning provided. The remaining proposals are distributed among B-tier (8 proposals requiring specific conditions), C-tier (7 proposals below the line), and TBD (2 proposals awaiting further data). This meticulous categorization highlights not only what the Protocol cluster intends to implement but also, crucially, what it has chosen to decline and why.
The companion document, "EF Protocol: Current and Emerging Priorities," is essential reading for anyone seeking to understand the overarching strategy, plan, and commitments that underpin every grade assigned in this tier list. It serves as the "north star" guiding the Protocol cluster’s efforts.
The Ethereum Protocol cluster is actively encouraging community engagement and feedback. A Reddit AMA (Ask Me Anything) is scheduled for September 16th at 2 PM UTC on r/ethereum, specifically dedicated to discussing the tier list. Champions and supporters of EIPs that were not ranked in the A tier or were declined are particularly encouraged to participate and voice their perspectives. Questions can be submitted in advance via a dedicated form.
