Ethereum’s Fusaka Upgrade Scheduled for December 3, 2025 to Boost Layer 2 Throughput with 12 EIPs

According to CoinDesk, COINOTAG News reports that Ethereum developers are preparing to roll out the network’s second upgrade of 2025 on the Ethereum mainnet on December 3, a Wednesday. The update, dubbed Fusaka—a portmanteau of Fulu and Osaka—will synchronize upgrades to the consensus layer and execution layer.

The upgrade aims to boost throughput by enabling faster interoperability with Layer 2 networks built atop Ethereum, improving scalability and reducing gas costs. Fusaka comprises 12 Ethereum Improvement Proposals (EIPs) designed to streamline the Layer 2 user experience and lower execution costs.

By aligning the consensus layer and execution layer pathways, Fusaka seeks to deepen cross-layer efficiency and support higher transaction volumes on Layer 2 ecosystems built atop Ethereum. The upgrade’s emphasis on speed and cost efficiency aligns with Ethereum’s broader scaling roadmap.
