Ethereum rolls out final planned Blob Parameters Only fork as final step in Fusaka upgrade

Ethereum developers finalized the Fusaka upgrade by deploying the second and final planned "Blob Parameters Only" (BPO) fork. This phased approach allows the network to safely test increased load step-by-step, adjusting specific parameters like blob targets independently and efficiently, rather than waiting for a major annual upgrade. Blobs, introduced in the Dencun upgrade, are temporary data chunks used by Layer 2 rollups for cheap transaction recording. The first BPO fork increased the target blobs per block from six to ten, and Wednesday's final update pushes this target to 14 and the maximum cap to 21. By incrementally raising these limits, Ethereum reduces data costs for rollups, helping to keep Layer 2 transaction fees low as activity grows, ensuring sustainable scaling.
