Ethereum EIP-8361 Proposal Would End Staking Incentives at 50% Supply

Ethereum researchers Justin Drake, Jérôme de Tychey, and Ladislaus von Daniels have proposed EIP-8361 to introduce a "Tapered Issuance Burn" mechanism. The proposal seeks to fundamentally alter the network's monetary policy by removing the guaranteed floor for staking rewards.

Under EIP-8361, the network would progressively burn a larger fraction of validator rewards as the total amount of staked ETH increases. Net consensus-layer issuance would drop to zero once staked ETH reaches a "SATURATION_BALANCE" of 60,250,000 ETH, representing approximately 50% of the total supply. To prevent a sudden shock to validator yields, the authors included an 18-month transition period that temporarily increases the base reward factor from 64 to 128. The immediate impact is significant: at current staking levels of roughly 33%, the net consensus yield would drop from approximately 2.6% to 1.2% if implemented without this transition period.

The Push Against Centralization

Currently, Ethereum's issuance curve ensures staking rewards never hit zero, maintaining a floor of roughly 1.5% regardless of how much ETH is staked. While this provides stability, proponents of EIP-8361 argue it creates a persistent incentive for more ETH to be locked away. This trend, they suggest, could lead to excessive centralization of stake within large custodians, exchanges, and ETF providers. Furthermore, there are concerns that the proliferation of liquid staking derivatives could eventually displace ETH as the primary collateral in the ecosystem.

Market Equilibrium and Risks

By introducing a "kill switch" for staking incentives, EIP-8361 aims to limit the growth of staked ETH to half the supply. This move is intended to increase asset scarcity and prevent the network from being captured by a few massive institutional stakers. The authors state that the burn "removes the floor and lets the market set the equilibrium instead."

However, this shift introduces significant volatility for validator revenue. It may also reduce the attractiveness of ETH as a yield-bearing asset for institutional investors who rely on predictable returns to justify their positions.

Community Friction

The proposal has sparked controversy due to its timing. According to The Defiant, EIP-8361 was submitted only 48 hours before the deadline for the Hegotá upgrade. Greg Koumoutsos, co-author of EIP-8148 and EIP-8205, criticized the timeline, stating that it "clearly doesn't leave adequate time for community review of a monetary policy change of this magnitude."

Whether the community will accept such a drastic shift in issuance remains the primary question as the Hegotá upgrade approaches, as the change would fundamentally redefine the economic relationship between validators and the network.
