Blob Space, Data Availability, and the Shifting Economics of Ethereum L2s

1/ Ethereum's EIP-4844 introduced dedicated blob space, slashing L2 transaction fees by over 90%. But how has this altered the economic equilibrium between rollups and the base layer? A quick look: 🧵

2/ With execution fees effectively near zero on networks like Base and Arbitrum, value capture shifts away from raw gas fees toward sequencer MEV and application-layer liquidity depth.

3/ For algorithmic traders and micro-task hunters, zero-fee L2s make sub-dollar transactions, automated rebalancing, and micro-yield farming viable without gas erosion eating the principal.

4/ As data availability alternatives (EigenDA, Celestia) compete with native blobs, modular rollup settlement is becoming the defining infrastructure thesis of 2026.
