Ethereum Developers Complete Final BPO Fork in Fusaka Upgrade Cycle

According to ChainCatcher, Ethereum developers have successfully completed the second and final 'Blob Parameters Only (BPO)' fork within 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 enhance the network's data availability capabilities. The official statement highlights that the BPO mechanism allows Ethereum to independently adjust critical parameters like blobs in phases, without waiting for major annual upgrades. This approach enables a more controlled testing and release of the network's capacity. Blobs were initially introduced in the 2024 Dencun upgrade to provide low-cost data storage for Layer 2 Rollups, with such data being automatically cleared from the mainnet after approximately 18 days. This adjustment is considered the final step in the Fusaka upgrade. Developers note that as the single-block blob limit gradually increases, Ethereum can offer more data space for Layer 2 networks, helping to maintain stable Rollup transaction costs amid growing on-chain activity.
