According to Cointelegraph, Foresight News reports that Tomasz Kajetan Stańczak, joint executive director of the Ethereum Foundation, revealed that the Fusaka hard fork is expected to take place in the third or fourth quarter of 2025, with the specific timeline yet to be determined. Core developer Tim Beiko confirmed that the controversial Ethereum Virtual Machine (EVM) object format (EOF) upgrade has been removed from Fusaka due to technical uncertainties and potential fork progress delays.
EOF contains 12 EIPs aimed at improving EVM efficiency by defining bytecode container modules, but its complexity has sparked controversy. Opponents like developer Pascal Caversaccio argue that it is "overly complex", introducing new semantics and modifying over a dozen opcodes, and potentially introducing new vulnerabilities.
