Odaily Planet News: Ethereum developers have completed the second and final "Blob Parameters Only (BPO)" fork planned during the Fusaka upgrade cycle. This update increases the target number of blobs per block from 10 to 14 and raises the upper limit from 15 to 21, aiming to further enhance the network's data availability capacity.
According to official statements, the BPO mechanism allows Ethereum to adjust key parameters such as blobs in a phased and independent manner, without waiting for large annual upgrades. This enables a more controlled approach to gradually testing and expanding the network's capacity. Blobs were initially introduced in the 2024 Dencun upgrade to provide low-cost data storage for Layer 2 rollups. This type of data is automatically cleared from the mainnet after approximately 18 days.
This adjustment is seen as the final step in the Fusaka upgrade. Developers noted that as the maximum blob size per block is gradually increased, Ethereum can provide more data space for Layer 2 networks, helping maintain stable transaction costs for rollups even as on-chain activity grows.
