Ethereum's upcoming Fusaka hard fork, scheduled for November 2025, is set to significantly boost the network's performance and DeFi potential. The upgrade incorporates 11 Ethereum Improvement Proposals (EIPs) aimed at enhancing scalability, node resilience, and efficiency. Notable changes include EIP-7594, which optimizes data availability sampling for rollups, and EIP-7825, designed to mitigate transaction spam risks. The 2025 roadmap focuses on increasing transaction capacity to 100,000 TPS, reducing gas fees, and improving data availability, all while maintaining smart contract stability. The upgrade also aims to enhance security and compatibility with institutional infrastructure, fostering greater institutional adoption. Economic benefits are expected from reduced transaction costs and deflationary pressures, with projects like Hyperliquid and Jupiter contributing to this trend. The Fusaka upgrade coincides with the Devconnect conference, highlighting Ethereum's strategic development timeline.
