Ethereum's blob usage climbed to a new all-time high this week as rollups pushed more data through the network's data layer than ever before. The network is running busier than at any prior peak, though it remains well short of its current capacity ceiling, and core developers are now debating when to raise that ceiling again.
Rollups drove Ethereum's blob usage to a new all-time high this week. The three-day moving average now sits at 5.9 blobs per block, with a daily average of 6.7, according to data highlighted by Protocol Guild organizer Trent van Epps.
Blobs are the cheap data slots rollups use to post batches to Ethereum, so more blobs per block means layer-2 networks are pushing more activity through the chain's data layer.
Usage has climbed back after a spring dip and now sits above the prior peaks recorded in late 2025. Even so, current activity runs at only about 40-50% of the current 14-blob target, leaving the network busy but not full.
Blob limits have been raised in stages since the Dencun upgrade, moving from 3/6, then 6/9 in Pectra, 10/15 in BPO1, and 14/21 in January's BPO2. Hits on the current 21 max remain rare.
Core developers have been debating when to lift limits again toward 21/32, weighing cheaper layer-2 fees against extra bandwidth load and the next gas-limit jump expected with Glamsterdam. The catch: keeping the scaling path moving still depends on client-team funding, which Protocol Guild argues remains thin for a chain of Ethereum's size.
