Ethereum (ETH-USD), the world’s largest programmable blockchain, has recently changed how it generates revenue. A series of protocol upgrades over the past year has shifted how value flows through the network, and those changes are starting to show up in ETH as an asset. The market does not yet seem to fully reflect that, making me cautiously bullish.

Ethereum is home to decentralized finance, stablecoins, and a growing network of Layer 2 (L2) networks that handle the bulk of its transaction activity. It trades around $2,300 at the time of writing, with a market cap of roughly $288 billion. Central to this scaling strategy is the use of “blobs” — specialized data packets that allow L2 to post transaction data to the mainnet at a fraction of the cost of traditional methods.
Blob Fee Market Is Surging
To better understand blobs, it helps to understand how Ethereum’s L2 networks work. Networks like Base, Arbitrum (ARB-USD), and Optimism (OP-USD) process thousands of transactions cheaply by bundling them together and periodically posting a compressed summary back to Ethereum for verification. Before March 2024, this was done by writing data directly into Ethereum’s permanent transaction history. That was expensive and took up space on the blockchain indefinitely.
Ethereum developers solved this challenge by creating a new type of temporary data package that carries L2 transaction summaries alongside a block, but is stored separately and deleted automatically after about 18 days. These packets are called blobs. Because they do not live permanently on the blockchain, they are far less expensive to use than the old method.
Blobs were introduced through a major Ethereum network update called the Dencun upgrade, which went live on March 13, 2024. L2 fees dropped by 90% or more almost immediately after launch.
The key detail for ETH holders is this: every blob transaction pays a fee to Ethereum, and that fee is burned permanently, removing ETH from circulation. The more L2 activity there is, the more blobs are posted, and the more ETH is destroyed.
Where the Problem Starts to Show
In the months after Dencun, blob fees worked almost too well. Because blob capacity was limited to just three per block and demand was moderate, fees often collapsed to near zero. L2 networks were effectively getting free data storage, while Ethereum captured almost none of the economic value it generated. The burn mechanism existed but had little fuel to run on.
Two structural fixes were needed: more blob capacity to handle growing demand, and a fee floor to prevent prices from collapsing to nothing during quiet periods.
How Two Upgrades Fixed the Problem
The first fix came in May 2025, when Ethereum rolled out a major network update called the Pectra upgrade. Among other changes, Pectra doubled the number of blobs allowed per block from three to six. That created more room for L2 activity and eased the fee spikes that occurred when demand exceeded the limit. The second update, called Fusaka, followed in December 2025. It tackled both remaining problems at once.
The first was capacity. As more L2 networks adopted blobs, the network needed to handle far more of them without slowing down. Fusaka solved this by introducing a smarter way to verify blob data, called PeerDAS. Instead of requiring every Ethereum node to download and check all blob data independently, PeerDAS distributes that work across many validators. Because the load is shared, it became safe to raise blob capacity much further.
Follow-up adjustments raised the blob target to 14 per block by January 2026, more than quadrupling the original limit. On the pricing side, Fusaka introduced a floor on blob fees. Previously, when demand was low, blob fees could fall to near zero, meaning Ethereum captured almost no revenue even as it supported billions in L2 activity.
The new floor ties the minimum blob fee to Ethereum’s regular transaction fee, so blob pricing always reflects real costs. Fidelity Digital Assets estimated that if this floor had existed since Dencun, it would have generated an additional $78 million in cumulative blob revenue.
How This Changes ETH Supply
Every blob fee is burned, permanently reducing the supply of ETH. Ethereum already has a mechanism for burning regular transaction fees, introduced in 2021. Blobs add a second, independent burn source that scales with L2 activity rather than with mainnet congestion.
At the time of the Fusaka launch, L2 networks were processing over 530 million monthly transactions, with a combined total value locked (TVL) of $39.4 billion. Industry estimates suggest blob fees could contribute 30–50% of total ETH burn by 2026.
Meanwhile, around 35.8 million ETH, roughly 30% of the total supply, is staked and earning rewards. Combined with fee burns, these two forces reduce the circulating supply and support the ETH price when activity is high.
The Risks to Watch
The blob burn mechanism is only as powerful as the L2 activity driving it. In a downturn, transaction volume falls, blobs get cheaper, and the burn rate slows. Ethereum’s deflationary story depends on sustained usage, not just protocol design.
Rival blockchains like Solana (SOL-USD) offer lower fees and faster speeds on a single-layer network. If developers migrate away, fewer blobs get posted, and the burn mechanism loses force.
A Structural Improvement, Not a Guarantee
Three upgrades in two years have turned Ethereum’s blob market from a subsidized service into a genuine revenue line with a functioning fee floor. At $2,300, ETH trades roughly 53% below its 2025 all-time high. The blob fee market is one of the clearest reasons to believe Ethereum’s utility and its price may converge. However, the pace depends entirely on whether L2 activity continues to grow.
