That is the EF Protocol cluster’s tier record for Hegotá. We evaluated the 62 EIPs proposed for inclusion, every with a tier and a brief notice on the grade.
It’s the first time the cluster has revealed one unified view slightly than per-team opinions. Geth, in fact, being an EL shopper will nonetheless ship their very own standalone tier record. Nevertheless, they and the remainder of the Protocol cluster (about 60 individuals in complete) throughout analysis and engineering labored collectively to incorporate their suggestions on this publish as a datapoint together with that of each different crew and particular person contributor that determined to take part.
The priorities that produced these grades are within the companion publish, EF Protocol: Present and Rising Priorities.
I. How we tiered
All 9 groups plus a number of particular person area consultants throughout the cluster stuffed out contribution templates, 16 in complete. Twelve supplied tier grades, and several other of these graded solely EIPs the place they’d deep experience. The result’s 397 tier grades throughout 62 EIPs, a mean of 6.4 grades per EIP with the most-discussed proposals drawing 9 grades.
Two retrospectives on Glamsterdam provided a number of classes (measurement an EIP by its integration depth; complexity compounds; testing floor is the scarce useful resource; champions usually underestimate complexity). Half a dozen group calls and a 90-minute working session lined the contested objects. The August 28 course of publish offers a bit extra element.
The scoring
Every contributor tiered every EIP independently: S = 4, A = 3, B = 2, C = 1, D/DFI = 0. Averages depend solid grades solely; an abstention by no means counts towards a proposal. The revealed tier is a steelman. It began from the grades and was argued EIP-by-EIP within the working session, with actions in each instructions. Per-team grades aren’t revealed.
Every degree of the tiered scoring ladder commits the cluster to supply expectations:
S – Should ship. Defines the fork. If an S merchandise is in danger, the schedule adjusts earlier than the scope does.
A – Excessive precedence, anticipated to ship. Dedicated alongside S-tier except supply actuality forces a reduce, and solely reduce earlier than any S merchandise is touched. All the pieces under S and A-tier have to be evaluated as soon as devnets with all S and A-tier EIPs are purposeful and secure.
B – On the bubble, included individually. By no means admitted in bulk. Every EIP to be thought of for inclusion separately as soon as devnets with all S and A-tier EIPs are purposeful and secure and time stays earlier than shifting to I*. Necessary to notice, most B-tiered EIPs carry 3 express necessities: a prototype, a sign-off, and a settled specification.
C – Beneath the road, not disqualified. First candidates for reconsideration if devnets containing S-, A-, and B-tier EIPs ship cleanly and time stays earlier than shifting to I*.
DFI – Declined for inclusion. Each DFI carries a structural rationale, like that the EIP is antithetical to CROPS, a safety danger, too prescriptive, introduces an middleman or chokepoint, breaks backward compatibility, or endangers the trail to J*.
TBD – Intentionally unranked. Held again till mainnet knowledge offers solutions to questions we can not reply at present.
The notice within the notes column of the desk for every EIP under ought to adhere to the next sample: For something we count on to ship, the notice offers the deserves. For something on the bubble, it names the precise necessities that may transfer it up a tier. For something under the road or declined, it offers the considerations and nothing else.
II. The tier record
The complete record as a single visible is on Forkcast. The tables under are sorted by tier, then by common inside every tier. Learn the grade depend beside each common.

Just a few notes on the A tier
Headliner packages: EIP-7805 (FOCIL) ships with EIP-8369 (VOPS Profiles for FOCIL Eligibility). EIP-8141 (Body Transactions) ships with EIP-8250 (Keyed Nonces for Body Transactions) and EIP-8272 (Latest Roots for Body Transactions) because the Frames core. Delivering each headliners safely, and testing the interplay between them, is the fork’s core engineering dedication.
Extension package deal: EIP-7906 (Transaction Assertions by way of State Diff Opcode), EIP-8298 (SETCODEFROM Code Reuse Instruction), and EIP-8151 (Account Code Restricted ecRecover). The primary hardens transactions immediately; the opposite two give an account a whole route away from k1 keys.
Just a few notes on the B and C tiers
Consensus layer EIPs blocked by further necessities: EIP-8198 (Fast Slots) has essentially the most demanding necessities on the record, together with specs masking all anticipated adjustments to the core protocol, a prototype implementing the complete specification, an in-depth evaluation of downstream results throughout the ecosystem, and sign-off that it doesn’t complicate decoupled consensus, which can’t be decided till that specification exists. The bar is ready the place it’s as a result of whereas the diff is small, the change will not be; slot time is load-bearing for timing assumptions throughout the protocol and the ecosystem, and discovering breakage late is how forks get delayed. EIP-8321 (Hash-Chain RANDAO) wants the entire PQ consensus design. EIP-8146 (Block Entry Record Sidecars) wants its statement deadline settled in specification. EIP-8237 (Impartial CL/EL Sync) wants a price comparability towards easier options and a supply proprietor.
Execution layer EIPs blocked by further necessities: EIP-8253 (Bump Nonce of Zero-Nonce Storage Accounts) is into consideration to maneuver to A-tier. It isn’t strictly required for the trie migration, and it simplifies the migration considerably, and the overview will resolve how a lot that simplification is price. EIP-8077 wants a settled wire format. EIP-8374 (Persist Heat Entry Units Throughout Reverts) and EIP-8358 (Internet Gasoline Metering for Account Adjustments) are one net-metering package deal and can’t carry totally different grades; resolving that’s an open overview merchandise.
TBD EIPs: EIP-8368 (CPSB Recalibration for New Gasoline Restrict) and EIP-8372 (Normalized State Gasoline Restrict) shall be evaluated collectively as soon as Glamsterdam hits mainnet and the affect of associated state repricings could be evaluated.
Just a few notes on the DFI block
The unanimous CL DFI block: EIP-8363 (Tapered Issuance Burn) and EIP-8375 (ePBS Obligatory Burn of Execution Rewards) belong to a broader issuance course of. EIP-8148, EIP-8205, and EIP-8359 are operational conveniences that primarily serve giant staking operations and fail the need bar. EIP-8142 (Block-in-Blobs) deepens KZG dependence towards the trail to J*.
One proposal deserves a direct notice: EIP-8363 (Tapered Issuance Burn). The unanimous DFI will not be a judgement on the deserves of the proposal. Issuance coverage touches each staker, each holder, and the community’s long-run safety finances; at this stage, EF Protocol doesn’t think about itself the appropriate and sole physique to provide path on it, and a fork scoping train will not be the appropriate venue to settle it. We’d count on this to be carried ahead by way of a multi-node ecosystem course of with the technical rigour and breadth of engagement the query deserves, and we intend to take part in such a course of.
III. In closing
Of the 62 proposals evaluated, 2 are must-ship, 15 are anticipated to ship, and 28 are declined with said causes. Of the 15 remaining, 8 are B-tier proposals with famous necessities for inclusion, 7 are C-tier proposals under the road, and a couple of TBD proposals ready on mainnet proof. Success right here is decided as a lot by what we decline as by what we ship.
In the event you learn one factor past this publish, please learn the companion: EF Protocol: Present and Rising Priorities, which incorporates the Protocol cluster’s north star, plan, and the commitments that produced each grade above.
And if a grade above deserves a problem, we’d love to listen to the pushback. We’re internet hosting a Reddit AMA on r/ethereum on September 16 at 2pm UTC, and the tier record is precisely what we count on to be requested about. Submit questions forward of time utilizing the shape right here. Champions and supporters of non-A-tier EIPs and declined EIPs are particularly welcome.
