Ethereum’s surprising usage drop suggests the network solved the wrong problem with Fusaka upgrade

Ethereum's Fusaka upgrade, activated in late 2025, significantly increased data availability capacity via Blob Parameter Overrides, raising the target from 6 to 14 blobs per block, with a maximum of 21. However, an analysis by MigaLabs shows that network utilization has not increased; median blob usage actually declined after the first adjustment. Furthermore, blocks containing 16 or more blobs exhibit elevated miss rates (up to 1.79% at 21 blobs), suggesting reliability degradation at the edges of the new capacity, which could pose risks if demand surges. While Fusaka successfully expanded technical capacity and implemented a reserve price floor (EIP-7918) to stabilize blob fees, the data indicates that Layer-2 rollups are not currently constrained by blob availability. The conclusion is that the network has ample headroom, and further capacity increases should be paused until utilization rises and infrastructure stabilizes at current high-blob loads.
