Ethereum researchers propose burning rewards to cap staking at half of supply
A draft EIP would burn validator rewards as staking climbs past 33%, testing institutional appetite for predictable ETH yields.
A group of six Ethereum researchers, including Ethereum Foundation figures Jérôme de Tychey and Justin Drake, has filed a draft proposal that would burn an escalating share of validator rewards as the proportion of staked ETH rises, reaching a full 100% deduction once staking hits roughly half of total supply. The measure, dubbed the “Tapered Issuance Burn” and circulated as EIP-8361, is intended to close a long-standing gap in Ethereum’s monetary policy: there is currently no mechanism that discourages staking beyond any particular threshold.
The proposal arrives days after the share of ETH supply locked in staking hit a record 33.33% on 28 July 2026, according to data cited by 21Shares. For a network whose issuance policy was last overhauled at the 2022 Merge, when execution-layer issuance was reduced to zero, the milestone has revived debate over how much of Ethereum’s circulating supply should realistically sit outside liquid, tradeable markets.
How the burn mechanism would work
Under the existing model, validator yield declines only with the square root of the number of active validators and never falls below a floor of roughly 1.5%, regardless of how concentrated staking becomes. Stakers currently share around 1,700 ETH in daily rewards, a figure that moves with the total amount staked.
The new proposal would instead deduct — and burn — a growing portion of each validator’s reward as the staking ratio rises, phased in gradually over 18 months to avoid an abrupt drop in yields. According to the authors, had the change taken effect immediately, net consensus yield at today’s staking ratio would fall from approximately 2.6% to around 1.2%, a reduction likely to push some stakers to exit.
Institutional pushback and the Bitmine question
The draft has drawn criticism from parts of the DeFi industry. Aave founder Stani Kulechov argued on X that capping rewards to zero above a 50% staking ratio would make ETH yields unpredictable and, in his view, uneconomical for institutional holders that rely on consistent cash flows for portfolio planning.
The concern is not purely theoretical. Bitmine Immersion Technologies, listed on the NYSE, has emerged as one of the largest single stakers of ETH, holding more than 5 million ETH — about 4.8% of circulating supply — after adding a further 150,120 ETH, worth roughly $278 million, on 4 August. That purchase took its total holdings to approximately 5.8 million ETH, intensifying scrutiny of concentration risk among large corporate treasuries participating in Ethereum’s proof-of-stake system.
Liquid staking protocols, which allow holders to stake ETH while retaining tradeable derivative tokens, currently hold a combined $34.9 billion in assets, with Lido alone accounting for $17.6 billion. A reduction in underlying consensus yields would flow directly through to returns on these products, potentially denting their appeal to both retail and institutional users who have treated staked ETH derivatives as a yield-bearing alternative to holding the asset outright.
Early-stage review, no upgrade slot yet
The proposal, submitted on 4 August 2026 by researchers including pintail-xyz, dapplion, pa7x1 and ladislaus0x alongside de Tychey and Drake, draws on earlier academic work by pa7x1 and Anders Elowsson. It is now undergoing public review on the Fellowship of Ethereum Magicians forum, where client teams and validators are expected to weigh in before any formal consideration for a future network upgrade. At submission, the thread had logged one negative and two positive reactions — an early and inconclusive signal of community sentiment.
Crucially, the EIP has not been assigned to any upgrade and carries no implementation timeline. For institutional allocators and regulators increasingly attentive to concentration in staking markets, the debate nonetheless underscores a tension at the heart of Ethereum’s economic design: the same proof-of-stake mechanics that secure the network also create incentives for capital to concentrate among the largest holders, a dynamic now drawing formal proposals to curb it.
