Ethereum Fusaka upgrade launched: PeerDAS allows the second layer network to "lightly equip"

[Coin World] Ethereum's second major move this year has arrived—on Wednesday, the Fusaka upgrade was officially activated, incorporating 12 EIP proposals in one go, with a clear core objective: to reduce the burden on layer two networks.

The most notable improvement is the optimization of PeerDAS. Previously, validators had to process the entire data block, but now it has changed to a “sampling mode,” where only parts of the data segments need to be verified. This move directly cuts down a significant portion of bandwidth consumption, reducing the costs for validators, and the transaction fees on the second layer are also decreasing.

In addition, there are some detail changes: the capacity limit for single transactions has been increased (reportedly related to security), and the operating efficiency of smart contracts has also been adjusted. Fidelity Digital Assets gave an evaluation - stating that this upgrade is a “strategic shift” in the Ethereum economic roadmap.

In simple terms, it means to continue to stubbornly pursue expansion and see if the Layer 2 ecosystem can truly take off.
