Ethereum Blob Usage Hits New All-Time High

Ethereum's blob usage has reached a new all-time high, according to data provided by Protocol Guild organizer Trent van Epps. The current three-day moving average stands at 5.9 blobs per block, with a daily average of 6.7.

Blobs are the cheap data slots that rollups use to post batches to Ethereum's data layer. With more blobs per block, L2s can put more activity through Ethereum's data layer.

The usage has climbed back after dipping in the spring and is now above prior peaks from late 2025. However, it's still only about 40-50% of the current 14-blob target, indicating that the network is busy but not full.

The blob limits have been raised in steps since Dencun, starting with 3/6, then 6/9 in Pectra, 10/15 in BPO1, and 14/21 in January's BPO2. Core devs are now debating whether to lift the limit again toward 21/32, weighing cheaper L2 fees against extra bandwidth load.
