Yilihua: The Fusaka upgrade has caused Ethereum blob fees to skyrocket due to the introduction of a fee floor in EIP-7918.

On December 5, Liquid Capital (formerly LD Capital) founder Yili Hua posted on social media, stating, “After Ethereum’s Fusaka upgrade, the blob base fee skyrocketed by 15 million times. The core reason is that EIP-7918 introduced a new ‘minimum guarantee mechanism’ for blob fees—previously, there was no minimum limit for blob fees, which were stuck at 1 wei (almost free) for a long time. This resulted in nodes bearing the costs of KZG verification without reasonable returns. After the upgrade, the blob fee must be at least 1/15.258 of the L1 execution base fee, directly pegging it to the actual network cost. This design allows prices to reflect actual resource consumption (preventing L2s from using network resources for free), adjusts blob traffic through price fluctuations to prevent congestion, and at the same time, PeerDAS technology has increased blob storage capacity. Additionally, blob fees are now included in the ETH burn mechanism. According to calculations, this could lead to up to 8 times more ETH being burned in the future, potentially contributing 30-50% of the total burned ETH by 2026 (the exact amount depends on the growth of L2 transaction volume).”
