Ethereum Draft EIP-8361 Would Burn a Rising Share of Validator Rewards as Staking Grows

A draft Ethereum proposal published on Aug. 4 by six authors, including Ethereum Foundation researcher Justin Drake, would burn an increasing portion of validator rewards as more ETH is staked. The approach would drive net consensus-layer issuance to zero once roughly 50% of ETH is staked. Filed as EIP8361 in a pull request and titled "Tapered Issuance Burn," the draft credits authors including Jérôme de Tychey, Ladislaus von Daniels and Drake. The authors argue that Ethereum's current issuance curve retains a key feature prior reduction plans did not remove: staking incentives never fully switch off. Under today's design, yield declines only with the inverse square root of the staking ratio and retains a floor of about 1.5% regardless of how much ETH is staked. In that framework, the point at which staking growth stops depends on whether the marginal staker's risk premium stays above that floor. The proposed burn removes the floor and leaves the equilibrium to market forces. The draft estimates about 33% of ETH is currently staked, or roughly 40 million ETH. At that level, the consensus layer pays about 1,054,000 ETH per year, equivalent to 2.62%. 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 through July 31, plus 190,000 locally built blocks valued at the same mean. On those assumptions, issuance contributes at least 93% of staking yield. How the burn scales Under EIP-8361, each epoch every validator would face a deduction for every assigned duty—attestations, block proposals and sync committee participation—calculated as a fraction of the idealized reward for that duty. The deducted ETH would be destroyed. The burn fraction is defined as 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, roughly half of the current supply of 120.7 million. At that level, the burn would exactly offset issuance for a performing validator. Above it, net consensus issuance would be zero. The draft emphasizes that the 50% staking ratio is a ceiling on incentives, not an objective for the network. It describes the saturation ratio as "not a target" and expects the market to settle below it where net yield matches the premium stakers require for liquidity risk, slashing risk, operational risk and regulatory risk. The deduction would apply whether or not the duty was actually performed. The authors say this preserves per-duty incentives because the balance difference between performing a duty and skipping it remains unchanged. A knock-on effect is slower recovery from outages, estimated at roughly 3.8x longer at today's staking ratio when measured in days of net earnings rather than in ETH. An 18-month phase-in Applied immediately at a fork, the mechanism would reduce net consensus yield at today's staking ratio from about 2.6% to about 1.2%. The authors say that would be "enough to prompt a substantial exit of stake on activation," so the change is designed to phase in over 18 months. The specification introduces TRANSITION_BASE_REWARD_FACTOR set at 128. The reward system would use a time-varying effective factor that decays linearly to the existing BASE_REWARD_FACTOR of 64 over 123,300 epochs. By doubling the factor initially, the net-yield curve is lifted to intersect the current curve at a 31% staking ratio, close to the network's current level, so stakers begin near today's yield. The taper still applies from the first epoch after activation: issuance would stop rewarding stake growth beyond 50% from day one. Large operators would feel the change first The draft says the current curve allows an operator's income to rise with each additional validator at any size and at any staking ratio because both its share of stake and total issuance grow. Under the tapered burn, total issuance is capped around a 20% staking ratio and declines beyond that point, meaning a growing operator would gain a larger slice of a shrinking pool. As a result, every operator reaches a point where adding more validators stops increasing income, and that point arrives sooner for larger operators. The draft estimates that an operator controlling half of all stake would stop being paid for further growth once about 31% of supply is staked. The authors note that MEV is not affected by the burn and continues to reward scale, which could push that threshold higher. The proposal frames its objectives as limiting the risk of Ethereum capture as more supply is concentrated with custodians, exchanges and ETF providers, and defending ETH's monetary role against staking derivatives that displace ETH as collateral. Liquid staking protocols hold $34.9 billion in value, according to DefiLlama, with Lido at $17.6 billion. ETH traded at $1,862 on Aug. 4, down 1.4% over the week. Review-window criticism The timing drew pushback shortly after publication. Greg Koumoutsos, a coauthor of draft EIPs 8148 and 8205, wrote in the Ethereum Magicians thread opened by lead author pintail that the proposal arrived 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 said the strawmap had set expectations that an issuance update would be considered for I*, a later placeholder fork. He also argued that earlier discussions had raised "legitimate arguments" about consequences of an issuance update that he said were not reflected in the draft. Aug. 6 is the pull-request deadline for EIPs targeting Hegotá, according to the agenda for All Core Devs — Consensus call #184. Hegotá is the upgrade after Glamsterdam; the Hegotá meta EIP indicates FOCIL is the only consensus-layer feature currently scheduled. As of publication, no pull request had been opened proposing EIP8361 for inclusion. The proposal is marked Draft, with type Standards Track and category Core, meaning it would require a hard fork. The draft says no execution-layer or contract changes are needed. The authors report an implementation has been completed in the Prysm consensus client, though test vectors are not yet included. In the forum thread, pintail credited coauthor pa7x1 for the core principle and Anders Elowsson for the per-duty burn structure. The Defiant has reported on Ethereum's issuance debate since it began.
