Ethereum scalability was boosted on Wednesday with the second Blob Parameter-Solely laborious 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 laborious 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 laborious fork additionally raised the blob goal from 10 to 14, which is broadly seen as an important metric to observe, as persistently approaching the 21-blob restrict may overload node bandwidth and storage.
One blob unit suits 128 kilobytes of knowledge, that means Ethereum can now retailer as much as 2,688 KB in a single block.
Blobs assist preserve the Ethereum mainnet secure
Whereas blobs increase transaction throughput on Ethereum layer 2s, additionally they assist stabilize fuel charges on the Ethereum mainnet because the community turns into much less congested.
YCharts data reveals that Ethereum transaction charges have been much more secure for the reason that first BPO laborious fork on Dec. 9, 2025.
Fuel restrict elevate additionally on the radar
Individuals within the Ethereum All Core Builders assembly on Dec. 15 additionally mentioned the concept of elevating the community fuel restrict from 60 million to 80 million as soon as the second BPO laborious fork was applied.

Doing that may straight improve the variety of transactions and sensible contract operations that may slot in every Ethereum block — additional boosting general throughput whereas probably reducing charges.
Glamsterdam laborious fork can also be targeted on scalability
Later in 2026, the Glamsterdam laborious fork will enable the fuel restrict to ratchet as much as 200 million and introduce “good parallel processing.”
Good parallel processing will develop into possible on Ethereum by 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.
