Rollup Economics: Who Pays for Data Availability?

The economics of rollup data availability have shifted dramatically since EIP-4844 introduced blob transactions. Where rollups once competed for L1 calldata space at premium gas prices, the blob fee market has created a new equilibrium -- one that fundamentally alters the cost structure of operating an L2.

Our analysis covers three critical dimensions: the blob base fee mechanism and its responsiveness to demand surges, the competitive dynamics between rollups sharing blob space, and the emerging strategies for batch compression that determine effective per-transaction costs.

Avg blob fee (wei) 142,847
Peak utilization 94.2%
Cost reduction vs calldata ~97.3%
Active blob posters 34

Key findings suggest that while data availability costs have plummeted, the distribution of these savings remains uneven. High-throughput rollups with efficient batching capture disproportionate benefits, while smaller chains face increasing relative costs as blob demand grows.
