Fusaka upgrade just flipped the script for Layer 2s. Blob fees skyrocketed 1500x overnight—literally from 1 wei straight to 1500 wei. We haven't seen L2 networks actually bleeding money for data posts since March, and now the pain is real.

Here's the thing: giants like Arbitrum and Optimism? They've got the muscle. Built-out infrastructure means they can pivot and optimize without breaking a sweat. But smaller L2 projects? They're hemorrhaging funds on every single blob submission right now. Not exactly a sustainable burn rate.

There's a light at the end though. Pectra drops December 9th, bringing 67% additional capacity to the table. That should ease the pressure—assuming these smaller players can survive till then.
