On Wednesday, Ethereum's scalability was enhanced with a second Blob parameter-only exhausting 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 exhausting 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 exhausting fork additionally elevated the blob purpose from 10 to 14. That is well known as a extra vital 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. Because of this Ethereum can retailer as much as 2,688 KB in a single block.

BLOBs assist preserve Ethereum mainnet secure
Whereas BLOBs enhance transaction throughput on Ethereum Layer 2, additionally they assist stabilize fuel charges on Ethereum mainnet by lowering community congestion.
YCharts information exhibits that Ethereum transaction charges have been far more secure for the reason that first BPO exhausting fork on December 9, 2025.

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

Doing so would straight enhance the variety of transactions and sensible contract operations that match into every Ethereum block, additional rising general throughput and doubtlessly lowering charges on the identical time.
Gramsterdam exhausting fork additionally focuses on scalability
In late 2026, the Gramsterdam exhausting fork will enhance fuel limits as much as 200 million and introduce “full parallelism.”
Full parallelism is now potential on Ethereum via 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.
