On November 30, Ethereum developers are preparing to launch the network's second upgrade of 2025 on the Ethereum mainnet on December 3 (Wednesday). This upgrade is named Fusaka (a combination of the names Fulu and Osaka) and will upgrade both the consensus layer and the execution layer of Ethereum. The goal of this upgrade is to enhance Ethereum's ability to handle large-scale transaction throughput from various Layer 2 networks, which use Ethereum as the base layer. Fusaka includes 12 code changes, known as Ethereum Improvement Proposals (EIPs), aimed at making the Layer 2 user experience faster and cheaper.
