Blob fees created a new cost component for rollup operators
After Dencun, rollups could publish data using blobs with a dedicated fee market rather than paying only calldata prices.
This introduced another network resource whose price responds to demand and available capacity.
Rollup teams gained a new lever for reducing user costs and managing data publication.
Cheaper data posting may benefit users, but pass-through depends on L2 fee policy and competition.
