Ethereum has hit another key milestone in its scalability roadmap with the Fusaka upgrade’s final Blob Parameters Only (BPO) fork.

“Instead of waiting for a major annual upgrade to adjust network capacity, BPO forks allow Ethereum to tune specific parameters (like blob targets) independently and efficiently,” said Ethereum in an X post.

This story is an excerpt from the Unchained Daily newsletter.

The second and final BPO fork raised the maximum blobs per block from 15 to 21 and the target from 10 to 14, completing the Fusaka upgrade’s parameter-only adjustments.

The change enhances data availability for rollups without a full hard fork, and could bring down layer 2 fees by up to 60% from current levels.
