#ETH走势分析 Ethereum is about to usher in its annual grand finale—the Fusaka hard fork is scheduled to go live at 5:49 AM Beijing time on December 4, 2025 (UTC time: December 3, 21:49). This upgrade is not just a simple version bump; it bundles together the Osaka proposal for the execution layer and the Fulu proposal for the consensus layer, continuing Ethereum’s long-standing tradition of “city naming.”

If the Pectra upgrade in May was just a warm-up, then Fusaka marks the full-scale push. This move directly targets the long-standing scaling bottleneck: boosting L1 performance, expanding Blob storage space, making Rollup fees more user-friendly, and even improving overall user experience. The real highlight is the introduction of the “Blob-only parameter,” a flexible adjustment mechanism that will allow the network to cope with surging Rollup demand without having to launch a major hard fork every time.

At the beginning of this year, the Ethereum Foundation announced its focus on three core areas: “scaling L1, expanding Blob, and improving user experience.” Fusaka is the first version to fully implement this combo, and in many ways, it marks a turning point for Ethereum from patchwork fixes to systematic planning. The direction for future scaling stories is set with this upgrade.
