Ethereum Foundation Proposes Validator Reward Burn to Take ETH Issuance to Zero at 50% Staking Ratio

Ethereum Foundation Takes Aim at Validator Rewards

In an intriguing development in the world of blockchain and cryptocurrency, Justin Drake from the Ethereum Foundation, along with five notable authors, put forward a draft proposal with a unique aim. Unveiled on August 4, the plan proposes a methodology to gradually eliminate — or “burn,” as it’s colloquially referred to — an increasing proportion of validator rewards as the amount of ether (ETH) staked expands. As a practical effect, this would effectively bring about net zero issuance at a staking ratio of 50%.

Details of the Ethereum Proposal

The recently announced proposal, termed as EIP-8361 in its pull request, carries the title “Tapered Issuance Burn.” It’s the joint endeavor of authors who include not just Justin Drake but also the likes of Jrôme de Tychey and Ladislaus von Daniels among others. The authors claim to take on a unique challenge that no previous plan aiming at reducing ether’s issuance curve has ever attempted: There’s currently no cap on the staking ratio at which there’s no further incentive to stake ether. Under the prevailing system, yields merely decline with the inverse square root of the staking ratio and maintain a near-constant floor of roughly 1.5%, irrespective of the amount of ether staked. This means the growth of the stake is always linked to whether the marginal stakers’ risk premiums remain above the said floor. Interestingly, this proposal seeks to remove that floor altogether, thus allowing the market to independently establish equilibrium.

Impact of the Proposed Changes on Ethereum Ecosystem

Currently, approximately 33% of ether, equivalent to around 40 million ETH, is staked. Concerning this configuration, the consensus layer distributes about 1,054,000 ETH yearly, translating to a percentage of 2.62. The draft points out that execution layer rewards add up to a maximum of 0.20%. In a post-proposal world, each validator would have a fraction of the reward for all their assigned duties—attestation, block proposal, sync committee participation—deducted and subsequently eliminated. This “burning” fraction takes the total active balance divided by a new constant, known as SATURATION_BALANCE, and raises it to the power of 3/2, limiting it to 100%. The SATURATION_BALANCE has been established at 60,250,000 ETH, which is nearly half of the existing supply of 120.7 million ether. At this level, the burn perfectly counters a validator’s issuance. Beyond this, consensus issuance becomes zero.

Moving Towards a New Ethereum Staking Mechanism

The authors have emphasized that the 50% figure is a maximum limit on incentive and not an achievement goal for the network. Further, the draft also envisages that the saturation ratio will not be targeted and that the market will likely settle at a lower ratio, the one where net yield meets the premium stakers demand. One notable aspect of the proposed changes is that the deduction is charged regardless of whether the assigned task was performed. This mechanism preserves the integrity of per-duty incentives by keeping the difference in balances – between executing a job and not doing it – constant. The proposed changes do come with some consequences. For instance, recovering from an outage will now take longer. It’s estimated that this period could extend up to 3.8 times longer at the existing staking ratio.

Concerns Over Timing and Application of the New Proposal

Interestingly, the proposed changes faced roadblocks almost instantly. Ethereum community member Greg Koumoutsos, objected that the proposal was tabled only 48 hours before the deadline to propose EIPs for the next Ethereum upgrade, Hegot, leaving no ample time for the community to review a monetary policy change of such magnitude. Despite reservations, it is safe to say that if the proposal is accepted and implemented successfully, it could herald a new era in the Ethereum ecosystem. The plan will likely have far-reaching implications for the Ethereum community and will fundamentally change the landscape for Ether stakers, setting the stage for a more autonomous, market-driven ecosystem.
