$ETH Ethereum’s Fusaka Upgrade Triggers Massive Spike in Blob Fees — What It Means for the Market
Ethereum’s recent Fusaka upgrade has caused a dramatic 15,000,000× surge in the blob base fee, driven by the new minimum fee mechanism introduced under EIP-7918. Previously, blob fees often sat at 1 wei — essentially free — leaving nodes to absorb the cost of KZG verification. The upgrade now requires blob fees to be at least 1/15.258 of the L1 execution base fee, aligning pricing with real network resource consumption.
This change forces Layer 2s to pay a fair share for data availability, uses fee fluctuations to regulate blob traffic, and pairs with PeerDAS to expand blob storage capacity. Importantly, blob fees are now part of the ETH burn mechanism, potentially boosting total ETH burning by up to 8×. Analysts expect blob-related burns to make up 30–50% of all ETH burned by 2026, depending on L2 growth.
Overall, Fusaka is reshaping Ethereum’s economics — tightening resource pricing, increasing burn pressure, and reinforcing the network’s long-term deflationary trend.
