Ethereum's EIP-4844 upgrade introduced blob-carrying transactions to give rollups cheap data space, creating a separate fee market. But five months in, the blob base fee is burning almost no ETH. As of mid-July 2026, Ethereum's chain revenue from blobs sits at about $55,700 per day — a tiny fraction of the $227,000 in daily L1 base fees. Meanwhile, rollup total value secured (TVS) has climbed to roughly $35 billion, with Base at $11 billion and Arbitrum at $10.4 billion. The disconnect is stark: more rollup activity isn't translating into more ETH burned.
How blob fees work — and why they're mostly idle
EIP-4844 gave each blob its own base fee, which gets burned like regular gas fees. The key difference: blob base fees only rise when blob space is tight. Right now, it's not. Rollups can publish batches cheaply, so the per-batch cost is low. And because the protocol burns the blob fee, less ETH gets destroyed per rollup batch when space is abundant.
Two burn lanes, one is barely lit
Ethereum now has two burn lanes: the L1 base fee for ordinary transactions and the blob base fee for rollup data. The L1 lane still does the heavy lifting — about $227,000 a day in mid-July. The blob lane contributes roughly a quarter of that, around $55,700 daily. With ETH supply at approximately 121.88 million, the net effect on supply is marginal. The burn only becomes significant when blob space gets scarce, which isn't happening yet.
Why burn stays low even as usage grows
Rollups can compress batches, and bigger batches with better compression mean fewer blobs per user action. That reduces aggregate blob demand even as total activity rises. Some L2s also choose external data availability — storing data off Ethereum — which cuts on-chain blob demand entirely. The result: more users, more transactions, but not necessarily more blob fees burnt.
When blob fees do spike
There are exceptions. Airdrops, farm seasons, and L2 incentive waves can temporarily push blob fees up. But those are short bursts. For now, the blob fee market is a sleepy backwater. Whether it ever becomes a real contributor to ETH's supply squeeze depends on how much data rollups actually need to post on-chain — and whether space ever gets tight enough to drive up the base fee.
