Ethereum: A Key Adoption Metric Hits a Record

The Ethereum crypto ecosystem has just recorded a new peak in its recent history. Since September 3, 2026, the demand for blobs (these cheap data spaces used by rollups) has reached levels never seen before. This performance attests to a growing adoption of layer 2 solutions. But not only that! It also validates Ethereum’s scalability strategy while reviving a less visible problem: funding its developers.

Why does Ethereum reach 6.7 blobs per block?

On September 3, Trent Van Epps, former member of the Ethereum Foundation and organizer of Protocol Guild, reported a moving average of 5.9 blobs per block over three days. The daily average even reached 6.7, which is well above the previous peaks from late 2025.

In Ethereum’s technical jargon, a blob refers to a cheap temporary storage space introduced by the Dencun upgrade (EIP-4844 standard) in 2024. Rollups are Layer 2 (L2) crypto networks like Arbitrum, Optimism, or Base. They deposit their batches of transactions there before having them validated by Ethereum’s main chain.

The principle is simple: the higher the number of blobs used per block, the greater the activity transiting through Ethereum’s data availability layer.

This record therefore means that Layer 2s publish more batches of transactions in Ethereum’s data layer. Each blob contains 4,096 elements of 32 bytes, about 128 KB. At 6.7 units, the theoretical volume thus approaches 858 KB per block.

How did Ethereum multiply its capacity by 2.3?

After a dip observed in spring 2026, blob usage on Ethereum has resumed rising. Even better! It now exceeds the previous peaks recorded at the end of 2025.

In reality, Ethereum’s blob capacity has steadily increased through successive steps since Dencun’s launch:

• 3/6 blobs (target/maximum) at Dencun launch in 2024;
• 6/9 blobs with the Pectra update;
• 10/15 blobs with the BPO1 step;
• 14/21 blobs with BPO2, effective January 2026 (the current level on Ethereum).

The Ethereum crypto network thus has 2.3 times more targeted capacity than before Fusaka. “Blobs offer rollups a less costly way to publish data on Ethereum,” explains the official documentation. EIP-4844 data disappears from nodes after 4,096 epochs, about 18 days. This lightens storage while maintaining verifiability during the useful period.

However, the Ethereum crypto network is still far from saturation. Indeed, current activity only represents 40 to 50% of the current target. This target is set at 14 blobs per block. The ceiling of 21 constitutes the technical limit per block. This margin still protects rollup transaction fees from structural spiraling.

Explanation: Ethereum is busy but not yet full.

What is at stake in the next capacity increase on the crypto blockchain?

The question now stirring Ethereum crypto developers is the timeline for a fifth increase targeting 21/32 blobs. For some, more blobs mean lower transaction fees for rollups and their users. The downside? Increased bandwidth load for Ethereum node operators.

For others, the bottleneck may especially become human. According to Trent Van Epps, for example, funding for client teams running Ethereum remains insufficient relative to the network’s size. In June, Ethereum core development required about 30 million dollars annually. Protocol Guild reportedly distributed nearly 40 million dollars in four years, yet that alone was not enough. Expanding data availability thus depends as much on human resources as on code.

That’s not all! This debate also fits within the perspective of Glamsterdam. This is the next major upgrade of the crypto network, which aims to raise Ethereum’s global gas limit.

In any case, this record of blob usage on Ethereum confirms the growing adoption of rollups. The next catalyst to watch: the outcome of the debate on an increase to 21/32 blobs.
