Ethereum's community is debating EIP-8363, a proposal that would cap the network's staking ratio by burning validator rewards once more than half of the ETH supply is staked. Ethereum Foundation researchers have flagged the uncapped ratio as a dilution and centralization risk since 2023, but Aave founder Stani Kulechov and other critics warn the fix would destabilize decentralized lending built on staking yield.
A ceiling on Ethereum's staking ratio
Ethereum's staking ratio has already climbed past 33% of the ETH supply, and the network's current issuance curve carries no cap on how high that ratio can go. Yield falls as more ETH gets staked, but it only bottoms out near 1.5% no matter how close the supply gets to being fully locked up.
EIP-8363 would change that. If enacted, validator rewards would keep accruing exactly as they do today, but a growing share would be burned as total stake rises, fully canceling consensus rewards once the staked share hits roughly 50% of the ETH supply. Past that line, validators would earn only from transaction tips and MEV until the ratio drops back below 50%.
Why researchers want a cap
The concern isn't new. Ethereum Foundation researchers have raised worries about the uncapped staking ratio since at least 2023.
Proponents argue that without a ceiling, a majority of ETH could concentrate among a handful of large staking operators, weakening the community's ability to fork against a captured validator set. They also warn that past a certain threshold, issuance turns into a permanent dilution tax on anyone who chooses not to stake.
DeFi critics push back
However, critics say the fix threatens decentralized lending built on staking yield. Aave founder Stani Kulechov argued the proposal would make staking yield unpredictable for institutional buyers and could undercut the case for borrowing ETH. According to Kulechov: "Ethereum should not be punished for its growth."
Skeptics also contend the burn would hit solo stakers hardest, since a home staker's hardware and electricity costs don't shrink along with yield. Proponents dispute this, arguing that because the burn scales with total stake already held, the point where adding validators stops paying off arrives earliest for whoever holds the most, not for smaller operators.
What happens next
EIP-8363 faces its cutoff today for Proposed for Inclusion status for the Hegotá upgrade, though nothing has been approved yet and Hegotá itself isn't expected on mainnet until next year. If it moves forward, the change would phase in over an 18-month transition period; if it stalls this week, the staking ratio keeps climbing and it remains to be seen whether the debate resurfaces down the road.
Whether Ethereum is overpaying for its own security remains unresolved, and EIP-8363 hasn't settled the question either way.
