Ethereum blob fees recently spiked to $4.52 due to heightened activity surrounding the Scroll layer-2 network's airdrop claims. This surge marked the third significant increase in blob costs since the Dencun upgrade in March. Analyst Hildobby pointed out that this marked the beginning of paid blob usage. Dune Analytics reported that on October 22, blob fees reached a four-month high. While increased blob fees contribute additional revenue to the Ethereum network, they also raise transaction costs on layer-2 platforms. Following the spike, blob fees rapidly fell back to near zero as L2 activity decreased. Ethereum co-founder Vitalik Buterin had previously warned about the blob capacity nearing full utilization. In response, developers proposed Ethereum Improvement Proposal 7742, which aims to dynamically manage blob capacity to enhance the Ethereum network's scalability.
