According to the Ethereum Foundation, this change can increase data capacity for rollups and Layer-2 networks by up to eight times. More capacity means rollups can handle greater traffic at lower costs.
The Foundation explained that this setup also helps maintain Ethereum’s decentralized structure while making it more affordable for users.
The organization also noted that the Fusaka upgrade moves Ethereum closer to offering near-instant transactions.
In a post on X, the Ethereum Foundation explained what the upgrade means for users, developers, node operators, and enterprises. In simple terms, Fusaka enables the network to process information more quickly, manage data more efficiently, and deliver a smoother overall experience.
Ethereum developers recently tested a new method that could make blockchain interactions more private using zero-knowledge proofs. How does it work? Read the full story.
