- Ethereum blob usage reached a record, with a three-day moving average of 5.9 blobs per block and a daily average of 6.7.
- Current demand uses only about 40% to 50% of Ethereum’s 14-blob target, leaving substantial capacity despite stronger rollup activity.
- Developers are considering another increase toward a 21-blob target and 32-blob maximum, balancing cheaper Layer 2 fees against higher bandwidth demands and limited client-team funding across the network today.
Ethereum’s blob usage has reached a new all-time high, signaling that rollups are pushing more data through the network’s dedicated scaling layer than ever before. A three-day moving average now stands at 5.9 blobs per block, while the daily average has climbed to 6.7. The record matters because blobs are the low-cost data slots rollups use to post transaction batches back to Ethereum. Higher usage therefore points directly to stronger Layer 2 demand for Ethereum’s data availability, even though current activity remains well below the protocol’s full capacity during this latest expansion phase for rollups.

Usage has rebounded sharply after a spring decline and now exceeds the previous peaks recorded in late 2025. Despite the new record, current demand represents only about 40% to 50% of Ethereum’s 14-blob target, meaning the system is active without approaching saturation. Ethereum is seeing record rollup demand while still retaining substantial unused blob capacity. The current maximum allows 21 blobs, but blocks hitting that ceiling remain rare, giving Layer 2 networks considerable room to expand before congestion becomes a persistent constraint under today’s configuration as adoption continues to increase across the ecosystem at present.
Ethereum’s Blob Capacity Has Expanded in Multiple Steps
Ethereum has progressively raised blob limits since Dencun introduced the mechanism. Capacity began at a target and maximum of 3 and 6 blobs, respectively, moved to 6 and 9 with Pectra, increased to 10 and 15 through BPO1, and reached 14 and 21 with January’s BPO2. The sequence shows Ethereum deliberately increasing data availability ahead of full demand rather than waiting for rollups to exhaust existing space. That approach helps preserve lower Layer 2 costs while creating more headroom for transaction batches as rollup activity continues to grow across the network over time for developers.
Developers are already debating another increase toward a 21-blob target and 32-blob maximum. The tradeoff is straightforward: more blob space could keep Layer 2 fees cheaper, but it would also raise bandwidth requirements as Ethereum prepares for another gas-limit increase in Glamsterdam. The next scaling decision will balance cheaper rollup execution against the operational cost of carrying more data. Progress also depends on continued funding for Ethereum client teams, an area Protocol Guild argues remains thin relative to the network’s size, making developer resources part of the capacity debate alongside raw technical demand today too.
