On Wednesday, Ethereum’s scalability was enhanced with a second Blob parameter-only onerous fork, rising the blob restrict from 15 to 21. That is the primary of many enhancements aimed toward scaling the Ethereum ecosystem in 2026.
The second BPO onerous 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 onerous fork additionally elevated the blob purpose from 10 to 14. That is widely known as a extra necessary metric to observe, as approaching the 21 blob restrict at any given time can overload a node’s bandwidth and storage.
One BLOB unit matches 128 kilobytes of knowledge. Which means Ethereum can retailer as much as 2,688 KB in a single block.

BLOBs assist maintain Ethereum mainnet secure
Whereas BLOBs enhance transaction throughput on Ethereum Layer 2, in addition they assist stabilize fuel charges on Ethereum mainnet by decreasing community congestion.
YCharts information exhibits that Ethereum transaction charges have been way more secure because the first BPO onerous fork on December 9, 2025.

Fuel limits raised on radar
Individuals on the Ethereum All Core Builders Convention on December 15 additionally mentioned the thought of rising the community fuel restrict from 60 million to 80 million as soon as the second BPO onerous fork is applied.

Doing so would straight improve the variety of transactions and good contract operations that match into every Ethereum block, additional rising total throughput and doubtlessly decreasing charges on the identical time.
Gramsterdam onerous fork additionally focuses on scalability
In late 2026, the Gramsterdam onerous fork will improve fuel limits as much as 200 million and introduce “full parallelism.”
Full parallelism is now potential on Ethereum by block entry lists primarily based on Ethereum Enchancment Proposal-7928. It goals to rework Ethereum’s single-lane mode of transaction processing right into a multi-lane freeway, additional rising transaction throughput.
