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.
