New Ethereum Proposal Would Burn Validator Rewards to Kill the Incentive to Stake More

Six authors including the Ethereum Foundation's Justin Drake published a draft proposal on Aug. 4 that would burn a growing fraction of validator rewards as more ETH is staked, taking net consensus-layer issuance to zero at a 50% staking ratio.

The draft, numbered EIP-8361 in its pull request, is titled Tapered Issuance Burn and is credited to authors including Jérôme de Tychey, Ladislaus von Daniels and Drake.

The proposal attacks the one property of Ethereum's issuance curve that no previous reduction plan removed: there is no staking ratio at which the incentive to stake more switches off. Yield falls only with the inverse square root of the staking ratio and keeps a floor of roughly 1.5% however much ETH is staked, so where stake growth stops depends entirely on whether the marginal staker's risk premium stays above that floor. The burn removes the floor and lets the market set the equilibrium instead.

About 33% of ETH is staked today, roughly 40 million ETH, and the consensus layer pays about 1,054,000 ETH a year, or 2.62%, according to the draft. Execution-layer rewards add at most 0.20%, based on the authors' count of about 72,600 ETH in MEV-Boost relay payments across 2.42 million blocks in the year to July 31, plus 190,000 locally built blocks priced at the same mean. Issuance therefore accounts for at least 93% of staking yield.

The Burn Rises With Stake

Each epoch, every validator would be charged a deduction for every duty it was assigned — attestation, block proposal, sync committee participation — sized as a fraction of the idealized reward for that duty. The deducted ETH is destroyed. The burn fraction is total active balance divided by a new constant, SATURATION_BALANCE, raised to the power of 3/2, capped at 100%.

SATURATION_BALANCE is set at 60,250,000 ETH, approximately half the current supply of 120.7 million. At that level the burn cancels a performing validator's issuance exactly. Above it, consensus issuance is zero.

The 50% figure is a ceiling on the incentive rather than a target for the network. The draft says the saturation ratio "is not a target" and expects the market to settle below it, at whatever ratio net yield meets the premium stakers demand for liquidity, slashing, operational and regulatory risk.

The deduction is charged whether or not the duty was performed, which is what keeps per-duty incentives intact: the balance difference between doing a job and skipping it is unchanged. One consequence is that recovering from an outage takes longer, by roughly a factor of 3.8 at today's staking ratio, measured in days of net earnings rather than in ETH.

An Eighteen-Month Cushion

Applied in full at the fork, the burn would cut net consensus yield at today's ratio from about 2.6% to 1.2% — "enough to prompt a substantial exit of stake on activation," the authors write. So the reduction phases in over 18 months. The spec adds a new constant, TRANSITION_BASE_REWARD_FACTOR, set at 128, and has the reward machinery read a time-varying effective factor that decays linearly to the existing BASE_REWARD_FACTOR of 64 across 123,300 epochs.

Doubling the factor lifts the net-yield curve to cross the current one at a 31% staking ratio, close to where the network sits, so stakers begin near today's yield. The taper's shape applies from the first epoch after activation regardless: issuance stops rewarding growth beyond 50% on day one.

Large Operators Hit First

Under the current curve an operator's income rises with every validator it adds, at any size and any staking ratio, because its share of the stake and the total issued both grow. The tapered burn caps total issuance at a staking ratio of roughly 20% and pushes it down beyond that, so a growing operator claims a larger share of a shrinking pot.

Every operator reaches a point where the second effect dominates, and the bigger the operator the sooner it arrives. An operator holding half the stake stops being paid for growth once about 31% of supply is staked, per the draft. The authors note MEV is unaffected by the burn and still rewards scale at any ratio, which pushes that threshold higher.

The proposal frames the goal in two parts: protecting Ethereum from capture as more of the supply sits with custodians, exchanges and ETF providers rather than its owners, and defending ETH's monetary role against staking derivatives that displace it as collateral. Liquid staking protocols hold $34.9 billion, per DefiLlama, with Lido alone at $17.6 billion. ETH traded at $1,862 on Aug. 4, down 1.4% over the week.

Two Days To Review

The timing drew an objection within hours. Greg Koumoutsos, a co-author of draft EIPs 8148 and 8205, posted in the Ethereum Magicians thread opened by lead author pintail that the proposal had landed 48 hours before the deadline to propose EIPs for Hegotá.

"This clearly doesn't leave adequate time for community review of a monetary policy change of this magnitude," Koumoutsos wrote. He added that the strawmap had set expectations that an issuance update would be considered for I*, a later placeholder fork, and that "legitimate arguments have been raised in various prior discussions about consequences of an issuance update that need to be considered but don't appear to be taken into account in this proposal."

Aug. 6 is the deadline for pull requests proposing EIPs for Hegotá, per the agenda for All Core Devs — Consensus call #184. Hegotá is the upgrade after Glamsterdam; FOCIL is its only consensus-layer feature scheduled for inclusion, per the Hegotá meta EIP. No pull request proposing EIP-8361 for inclusion had been opened as of publication.

The status is Draft, the type Standards Track and the category Core, so the change requires a hard fork. No execution-layer or contract changes are needed. The authors say an implementation has been completed in the Prysm consensus client. Test vectors are not yet included.

In his forum post, pintail credited co-author pa7x1 for the core principle and Anders Elowsson for the per-duty structure of the burn. The Defiant has covered Ethereum's issuance debate since it opened.
