EIP-7915는 블롭 가격 책정에 적응형 평균 회귀(adaptive mean reversion) 메커니즘을 도입하는 Stagnant 상태의 Core 제안입니다. 블롭 수요 변동에 더 빠르게 반응하는 가격 모델을 통해 EIP-4844의 기본 수수료 메커니즘을 개선하려 했습니다.
Background
EIP-4844 introduced blob transactions with a separate fee market. The base fee adjustment mechanism uses an exponential formula similar to EIP-1559, but critics argued it responds too slowly to sudden demand spikes.
Proposal
EIP-7915 proposed replacing the static adjustment rate with an adaptive mean-reversion model that increases its response speed when observed blob usage deviates significantly from the target.
Why It Stalled
The adaptive model introduces additional complexity and the parameterization is sensitive. Simulations showed mixed results and there was insufficient evidence that the current mechanism is broken enough to warrant the change.
Historical Context
Blob fee market design is an active area of research. EIP-7915 contributed useful analysis but the community preferred to gather more real-world data before modifying the fee formula.
