Yi Lihua: Ethereum Fusaka upgrade caused blob base fees to surge 15 million times due to the addition of a "guaranteed return mechanism" in EIP-7918.

Liquid Capital founder Yi Lihua published an article on the X platform stating that the Ethereum Fusaka upgrade caused the blob base fee to surge by 15 million times. The core reason is the new "minimum guarantee mechanism" for blob fees added by EIP-7918. Previously, there was no minimum limit on blob fees, which were stuck at 1 wei (almost free) for a long time, causing nodes to bear the costs of KZG verification but without reasonable returns. After the upgrade, the blob fee must be ≥ 1/15.258 of the L1 execution base fee, directly anchoring to the real network cost.
