#Gate广场创作者新春激励 Ethereum completes the final BPO fork of the Fusaka upgrade, further enhancing data availability limits

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 (the carriers used for low-cost data storage in Layer2 Rollup) in each block from 10 to 14, and raises the upper limit from 15 to 21, aiming to further improve the network's data availability capacity.
Officially, the BPO mechanism allows Ethereum to independently adjust key parameters such as blobs in phases without waiting for large annual upgrades, enabling more controlled testing and release of the network's carrying capacity. Blobs were initially introduced in the 2024 Dencun upgrade to provide low-cost data storage for Layer2 Rollups. Such data is automatically cleared after approximately 18 days on the mainnet.
This adjustment is seen as the concluding step of the Fusaka upgrade. Developers note that as the upper limit of blobs per block gradually increases, Ethereum can provide more data space for Layer2 networks, helping to maintain stable transaction costs for Rollups amid growing on-chain activity.

On January 8, Ethereum founder Vitalik Buterin wrote a post comparing Ethereum's vision and positioning. Ethereum is similar to BitTorrent (a peer-to-peer network), combining decentralization with large-scale applications. Ethereum aims to do the same but adds a consensus mechanism. Ethereum is also akin to the Linux operating system. Linux is free, open-source software that is uncompromising, relied upon silently by billions of people and enterprises worldwide, and even used by governments. Many Linux-based operating systems pursue large-scale adoption, while others, like Arch, are highly pure, minimalist, and technically elegant Linux distributions focused on empowering users rather than comfort.
We must ensure that Ethereum L1 serves as a financial (ultimately including identity, social, governance, etc.) home, providing those seeking higher autonomy with direct access to the full power of the network, without relying on intermediaries. Meanwhile, the example of Linux proves that providing value to large populations is compatible and can even be loved and trusted by global enterprises.
