Ethereum Fusaka hardfork set for December rollout: what does it mean?

Ethereum Fusaka hardfork set for December rollout. [https://invezz.com/wp-content/uploads/2025/09/20250919_090455_rqX3f.png] Ethereum developers have finalised a December launch for the network’s next major hard fork, dubbed Fusaka, which is expected to make the layer 1 network more efficient and secure. According to Ethereum researcher Christine D. Kim, who reported the development, the first rollout phase is set to begin on Dec. 3, followed by a second upgrade around Dec. 17 that will increase blob capacity. A third blob capacity hard fork is scheduled for Jan. 7, 2026, and together, these three upgrades will more than double Ethereum’s current blob throughput. For those unaware, blobs are temporary off-chain data chunks that were first introduced in the Dencun upgrade to help rollups post large volumes of data more efficiently without congesting the main chain. By storing this data separately and only referencing it on-chain, blobs significantly reduce transaction fees on layer-2 networks and, therefore, have been touted as a key part of Ethereum’s scaling roadmap. Initially, developers were targeting a November rollout, but those plans have since been delayed. Before the hard fork begins, Ethereum…
