Ethereum Improvement Proposal EIP-8363, known as "Tapered Issuance Burn," has sparked fierce opposition from DeFi builders, staking providers and institutional investors. The proposal would gradually reduce staking rewards, targeting zero protocol issuance once 50 percent of ETH's total supply is locked in validation.
Authors Justin Drake of the Ethereum Foundation and Jerome de Tychey, co-founder of the Ethereum Community Conference, argue that Ethereum has reached a point where additional staking offers diminishing security returns. They contend that continued issuance dilutes non-staking holders and that the network should cease subsidizing staking once sufficient security is achieved.
Ethereum currently has approximately 41.5 million ETH staked—34.07 percent of total supply—earning validators a 2.67 percent yield.
Mike Silagadze, founder of Ether.fi, said EIP-8363 poses a threat to DeFi. He argued that liquid staking, a core DeFi primitive, relies on healthy staking yields. Reducing these yields would negatively impact the broader ecosystem.
Dr. Steve Berryman, Bitwise's head of client partnerships for Ethereum, views EIP-8363 as solving a problem that does not exist. Market forces, he said, are already naturally slowing staking participation without changes to Ethereum's issuance policy.
Berryman pointed to staked ETH growth of 15 percent since the beginning of 2026, suggesting the network will reach a "natural ceiling probably by the end of this year." Yields falling to around 2 percent are unlikely to attract significantly more ETH for staking, he added, because "people need a certain amount of liquidity."
Recent staking growth has been driven largely by institutional entrants including Bitmine and BlackRock. Berryman expects institutional participation to slow once these players complete their initial allocations.
The debate reflects broader disagreement over the optimal balance between network security, validator incentives and ecosystem health.
