#以太坊技术发展 Analyzing the changes in blob fees after the Fusaka upgrade, it was found that the main reason for the surge of 15 million times is the "minimum guarantee mechanism" introduced by EIP-7918. This design links blob fees to the L1 execution base fee, ensuring reasonable pricing for network resource usage. From a technical perspective, this not only better reflects actual costs but also allows for traffic regulation through price fluctuations to prevent congestion. It is worth noting that after blob fees are incorporated into the ETH burn mechanism, it is expected to significantly increase ETH burn volume, which could have an important impact on Ethereum's future deflationary nature. This upgrade demonstrates Ethereum's ongoing optimization of its technical and economic models, and its long-term effects are worth close attention.
