Ethereum Fusaka Upgrade: The Economic Logic Behind Blob Fee Surging by 15 Million Times

2025-12-05 15:30:20

[Chain News] Ethereum’s Fusaka upgrade made a huge move—the blob fee skyrocketed by 15 million times. What’s going on?

Simply put, the previous pricing mechanism was ridiculous. Blob fees were stuck at 1 wei for a long time, basically making it free, and nodes had to pay out of pocket to perform KZG verification. This time, EIP-7918 set a “floor price” for blobs: it can’t be lower than 1/15.258 of the L1 execution fee. Now, prices can finally reflect the real costs.

This design is pretty smart. First, it stops L2s from endlessly exploiting cheap blobs, and second, the price fluctuation can automatically regulate traffic and prevent network congestion. Combined with PeerDAS technology to expand storage capacity, the whole system’s efficiency is maxed out.

What’s even more impressive is that blob fees now go into the burn pool. Liquid Capital founder Yilihua crunched the numbers: in the future, ETH burn volume could increase eightfold, and by 2026, blob-related burns could account for 30-50%—of course, assuming L2 transaction volume keeps up.

This upgrade is essentially a major overhaul of Ethereum’s resource pricing system, which will benefit the long-term health of the ecosystem.

Oh wow, 15 million times? That just shows how ridiculous and broken the previous mechanism was, haha. The days of easy airdrop farming are definitely over. Now with this floor price set, L2s are getting hit hard. But seriously, what's really interesting is that blob fees will also be burned. This move by Ethereum is really ruthless.

Damn, 15 million times increase, this growth is insane, L2s must be crying. The era of freebies is really over, it was about time to start charging. Now blob fees are finally valuable, the previous pricing mechanism was really absurd.
