Will Fusaka keep users on L2? Upcoming Ethereum upgrade eyes up to 60% fee cuts

The upcoming Ethereum upgrade, named Fusaka (a hybrid of "Fulu" and "Osaka"), is designed to enhance data availability and efficiency, primarily targeting lower fees on Layer 2 rollups rather than Layer 1 itself. Key technical changes include EIP-7594 (PeerDAS), which allows nodes to sample only data fragments ("blobs") instead of downloading everything, drastically lowering validator bandwidth costs. EIP-7892 introduces Blob Parameter-Only (BPO) forks for gradual capacity scaling, and EIP-7918 sets a base-fee floor for blobs. For users, Fusaka is expected to cut L2 fees by 15% to 40%, potentially reaching 60% under certain conditions, while also improving user experience via EIP-7951, which adds WebAuthn support for passkey logins. The upgrade solidifies Ethereum's modular architecture, positioning L1 as the secure settlement and data hub while L2s handle the bulk of user activity, making the L2 experience smoother and cheaper, thus ensuring users remain on rollups.
