The Ethereum Fusaka upgrade is getting serious this time—the way blob fees work has completely changed.

Yi Lihua from Liquid Capital revealed a staggering number: blob fees have skyrocketed by 15 million times. This isn’t just hype—previously, blob data fees hovered at 1 wei for a long time, which was basically zero cost, and nodes couldn’t even recoup their electricity costs for processing these scaling data packets. Now, with the implementation of EIP-7918, a hard lower limit has been set for blob fees: they must reach at least 1/15 of the mainnet gas fee.

What does this mean? Resource usage now has a real cost. Want to push data onto the Ethereum mainnet? You have to pay the market rate first.

Even more crucial is the chain reaction in the deflationary mechanism. Blob fees are now involved in ETH burning, and some estimates show the burn rate could increase eightfold. By 2026, this portion of burning could account for 30%-50% of the total burned ETH. The more active L2 networks are and the more blob resources they consume, the more aggressively ETH is burned. The logic of tightening supply is straightforward.

Will L2 costs be passed on to users? Maybe not that simple. The upgrade also introduced PeerDAS technology, which has expanded blob storage capacity—so while the unit cost has increased, supply is also rising. L2 projects have room to absorb some of these costs through technical optimization, so user fees may not rise significantly.

Essentially, this is Ethereum repricing network resources: node services are now valuable, data storage is no longer free, and ETH can become even more scarce in the process.

How do you think this combo move will play out? Will L2s launch blob fee subsidy programs? Or will they just double down on tech optimization?
