The CEO of one of Ethereum’s largest corporate treasury holders is picking a public fight with some of the network’s most influential researchers. Joseph Chalom, who leads SharpLink (Nasdaq: SBET), came out against Ethereum Improvement Proposal 8363 on August 7, arguing the proposal could hollow out DeFi activity and erode ETH’s competitive edge against Bitcoin.
At the heart of the dispute is a mechanism that sounds innocuous but could fundamentally rewire Ethereum’s economic incentives: a “Tapered Issuance Burn” that would progressively destroy validator rewards as more ETH gets staked.
What EIP-8363 actually proposes
The proposal, introduced on August 4 by Ethereum researchers including Justin Drake and Jérôme de Tychey, targets a specific staking threshold: 60.25 million ETH, roughly 50% of the current total supply. Once staked ETH approaches that level, the consensus-layer rewards that validators earn would begin burning away. Cross that threshold, and those rewards drop to zero.
That’s a bigger deal than it might sound. Currently, about 85% of staking rewards come from consensus-layer issuance, with the remaining 15% from tips and MEV (maximal extractable value, the profit validators capture from reordering transactions). Eliminating the issuance component would wipe out the vast majority of what validators earn for securing the network.
The phase-out would happen gradually, over roughly 18 months. Proponents frame it as a necessary inflation control measure, one that would also prevent staking from becoming too concentrated among large custodial players who can afford to operate at razor-thin margins.
The case against burning validator rewards
SharpLink’s Ethereum treasury has been previously estimated at around $3B, making Chalom’s opposition more than academic. He has real skin in the game, and his argument centers on second-order effects that the proposal’s architects may be underweighting.
First, there’s the yield question. Ethereum’s staking yield is one of the asset’s key selling points for institutional investors, particularly those comparing ETH to Bitcoin. BTC generates no native yield. ETH does. Remove that yield, and the calculus for allocating capital between the two largest crypto assets shifts meaningfully.
Second, there’s the DeFi domino effect. Staking yields serve as a kind of risk-free rate for the Ethereum ecosystem. DeFi borrowing rates, liquid staking token strategies, and restaking protocols all calibrate against the base staking return. Pull that floor out, and the entire yield curve for Ethereum-based financial products gets distorted.
Liquid staking tokens, which represent staked ETH and have become foundational building blocks in DeFi, would see their underlying returns crater. Protocols built on top of LSTs would need to find alternative sources of yield or risk becoming economically unviable.
That last point is where Chalom sees a particularly dangerous feedback loop. Ethereum already burns a portion of every transaction fee through EIP-1559, which has been live since 2021. If DeFi activity declines because staking yields have evaporated, fewer transactions mean less fee burn, which means less deflationary pressure on ETH supply. The proposal could, paradoxically, make Ethereum more inflationary by trying to make it less so.
A philosophical divide in Ethereum governance
This debate reflects a deeper tension in how Ethereum should evolve after the Merge. On one side are researchers who view excessive staking as a systemic risk, one that concentrates power among large custodial entities. On the other side are holders, treasury managers, and validators who see staking rewards as the economic backbone of Ethereum’s security model.
Chalom’s position aligns with other industry voices who argue that Ethereum’s existing base-fee burn is already doing the deflationary work without requiring a second mechanism that directly targets validators.
The timing of this debate matters. Ethereum has spent years building institutional credibility, from the Merge to the approval of spot ETH ETFs in the US. Corporate treasuries like SharpLink’s represent exactly the kind of adoption the ecosystem has been courting. Proposing to eliminate 85% of staking rewards just as that institutional pipeline matures is, at minimum, a risky strategic move.
