EIP-8361 Would Cut Ethereum Staking Yield to Zero at 50%

Six authors submitted the proposal through GitHub on August 4, and the group includes Ethereum Foundation researcher Justin Drake. The document, titled “Tapered Issuance Burn,” is still a Draft, so nothing changes on the network yet.

How the Tapered Issuance Burn Works

The idea is simple at its core. At each epoch boundary, the network deducts and burns a fraction of every validator’s idealised duty reward. That reward covers attestations, block proposals, and sync committee work.

The burn fraction is not fixed. Instead, it rises with the staking ratio, meaning the total active balance divided by the total supply. So the more ETH people stake, the larger the share of rewards the network destroys.

According to the EIP, the burn fraction follows a set formula. It is b(f) = (f / 0.5) raised to the power 1.5, capped at 100%. As a result, the burn reaches full strength near half of the ETH supply. You can read the full spec in GitHub pull request 12081.

Why Ethereum Staking Yield Falls to Zero at 50%

Today the network pays consensus rewards in proportion to 64 divided by the square root of the total active balance. Because of that math, yield falls only slowly as staking grows. Even at full participation, a positive floor of roughly 1.5% would remain.

That floor creates constant pressure to stake more ETH. EIP-8361 removes it. The burn cancels a growing slice of issuance. So net Ethereum staking yield declines faster and hits zero at a 50% staking ratio.

The math here is exact rather than approximate. At or above half of supply staked, the burn wipes out 100% of issuance. Therefore stakers above that line earn no net consensus reward at all.

Current numbers show why this matters now. About 41.6 million ETH sits staked today, or roughly 34% of the 122 million supply, according to ultrasound.money. Nominal Ethereum staking yield sits near 2.6%, almost entirely from consensus issuance.

An 18-Month Transition to Soften the Cut

The authors clearly anticipated a shock to staker income. So the proposal pairs the new curve with an 18-month transition period. During that window, the network temporarily lowers the base reward factor impact so the absolute cut phases in gradually.

The curve shape itself turns on from day one of any activation fork. Still, the transition matters. Stakers would start near today’s yield, then slide toward the permanent curve over 18 months.

Consider the current staking level as an example. At 33% staked, the EIP estimates a full activation would cut net yield from 2.6% to 1.2%. Co-authors have described that as a rough halving toward 1%. That framing tracks the EIP’s more precise 1.2% figure.

What EIP-8361 Means for Stakers and LSTs

Solo stakers keep the same micro-incentives, because performing duties still pays something. However, they face lower absolute returns and fixed operating costs that do not shrink. That combination worries home stakers the most.

Liquid staking protocols like Lido and Rocket Pool would also feel the squeeze. As base yields compress, any equilibrium above roughly 40% to 45% staked starts to look unattractive. In turn, that could slow the growth of liquid staking tokens and EigenLayer restaking.

The authors frame this outcome as a feature. In the abstract, they argue the change “removes the yield floor implicit in the current curve.” It would let the staking market settle where yield meets the risk premium stakers demand. For a positive premium, they expect that point to sit below 50% staked.

The Pushback From Home Stakers and DeFi

Reaction on X has been engaged but skeptical. Home stakers argue that near-zero yields hit small operators first. Their fixed costs eat a larger share of thinner rewards. Some warn of a drift toward large, professional operators.

DeFi voices raised a different concern. Aave founder Stani Kulechov called the proposal “hurtful for Ethereum.” Other lending-market participants warned that unpredictable yields could damage institutional demand and ETH borrowing markets. The timing also drew fire, because the proposal landed just before a Hegota fork planning deadline.

The authors pushed back in turn. They argue the current curve already forces yields lower through dilution and taxes solo stakers first. Moreover, they note the taper preserves execution-layer income and never pushes a correct attester into negative rewards.

What Happens Next for EIP-8361

Plenty remains unsettled. Editors have not merged the draft to the main EIP repository, and no hard fork has adopted it. The final saturation balance and the long-term equilibrium staking ratio are still open questions.

Some signals point to momentum, though. The client team behind Prysm has reportedly built a prototype implementation already. The Ethereum Magicians thread is active, and core researchers are debating the parameters in public.

For now, EIP-8361 reopens the long-running issuance debate rather than settling it. Watch the pull request and the Magicians forum for the next round of edits. This article is not financial advice, and staking returns depend on parameters that could still change.
