PANews reported on December 4th that the official Ethereum X account tweeted that Ethereum successfully activated the Fusaka upgrade at epoch 411392 (05:49 Beijing time on December 5th). This upgrade introduces the PeerDAS mechanism, increasing Rollup data throughput by 8 times. It also optimizes user experience through R1 curves and pre-confirmation mechanisms, and prepares for future scaling, such as increasing the L1 gas limit. The community will continue to monitor the system's operation over the next 24 hours.
