Following the Ethereum Fusaka upgrade, blob base fees surged by 15 million times. The core reason is the new "minimum guarantee mechanism" for blob fees introduced in EIP-7918. Previously, blob fees had no minimum limit, consistently hovering around 1 wei (almost free), causing nodes to bear costs such as KZG verification without reasonable returns. After the upgrade, blob fees must be at least 1/15.258 of the L1 execution base fee, directly anchoring to real network costs. This design allows prices to reflect actual resource consumption (preventing L2 from occupying network resources for free), regulates blob traffic through price fluctuations to prevent congestion, and increases blob storage capacity through PeerDAS technology. Furthermore, blob fees are incorporated into the ETH burning mechanism, which is estimated to burn up to 8 times more ETH in the future, potentially contributing 30-50% of the total burned amount by 2026 (depending on L2 transaction volume growth).

L1-L2 collaboration will also be deepened, because this will directly link L2 costs to L1 base fees, prompting L2 to pay more attention to the L1 network status and promoting collaborative optimization at the ecosystem level.
