The Ethereum Fusaka hard fork is expected to take place in late 2025

Ethereum Foundation officials said the Ethereum Fusaka hard fork is expected to take place in the third or fourth quarter of 2025, but the specific release schedule has not yet been determined. Tim Beiko, a core developer of Ethereum, confirmed that "EOF has been removed from the Fusaka network upgrade" because the developers believe that "there are technical uncertainties and may lead to a time lag in the launch of Fusaka". EOF originally planned to introduce a scalable and version-controlled format for smart contract bytecode containers through a series of Ethereum Improvement Proposals (EIPs), but was opposed due to complexity and the risk of introducing more vulnerabilities.
