Six weeks after Ethereum raised its per-block blob target, median fees on the four largest rollups have fallen well below a cent for simple transfers, according to network data reviewed by this newsroom.
The relief is real but uneven. Data availability is no longer the binding constraint for most rollups; sequencer throughput and proof generation now dominate latency during volatile hours.
Researchers tracking the change caution that cheap blobs also weaken a source of validator revenue that some economic models assumed would grow with rollup adoption.
Several teams are experimenting with shared sequencing to smooth demand spikes, though none has committed to a production launch date.
The next scheduled parameter review will decide whether the target rises again or holds, and validator client teams have asked for at least one more full cycle of data before another increase.
