Ethereum scalability was boosted on Wednesday with the second Blob Parameter-Solely arduous fork, elevating the blob restrict from 15 to 21, the primary of many enhancements aimed toward scaling the Ethereum ecosystem in 2026.
The second BPO arduous fork, which took impact on Wednesday at 1:01:11 UTC, additional will increase Ethereum’s information throughput by permitting extra transactions to be batched by way of rollups.
The BPO arduous fork additionally raised the blob goal from 10 to 14, which is extensively seen because the extra essential metric to observe, as constantly approaching the 21-blob restrict might overload node bandwidth and storage.
One blob unit matches 128 kilobytes of knowledge, which means Ethereum can now retailer as much as 2,688 KB in a single block.

Blobs assist maintain Ethereum mainnet regular
Whereas blobs increase transaction throughput on Ethereum layer 2s, additionally they assist stabilize gasoline charges on the Ethereum mainnet because the community turns into much less congested.
YCharts information reveals that Ethereum transaction charges have been much more secure for the reason that first BPO arduous fork on Dec. 9, 2025.

Gasoline restrict increase additionally on the radar
Contributors within the Ethereum All Core Builders assembly on Dec. 15 additionally mentioned the thought of elevating the community gasoline restrict from 60 million to 80 million as soon as the second BPO arduous fork was applied.

Doing that may immediately enhance the variety of transactions and good contract operations that may slot in every Ethereum block — additional boosting general throughput whereas probably reducing charges.
Glamsterdam arduous fork can be centered on scalability
Later in 2026, the Glamsterdam arduous fork will permit the gasoline restrict to ratchet as much as 200 million and introduce “good parallel processing.”
Good parallel processing will turn out to be possible on Ethereum by means of Block Entry Lists underneath Ethereum Enchancment Proposal-7928, which seeks to rework Ethereum’s single-lane mode of transaction processing right into a multi-lane freeway, additional rising transaction throughput.
