According to reports by Wu, the Ethereum Fusaka hard fork is expected to take place in the third or fourth quarter of 2025. The originally planned upgrade to include the EVM Object Format (EOF) has been canceled due to technical uncertainties and potential delay risks. The EOF aims to improve the execution efficiency of smart contracts and reduce overhead by standardizing bytecode structure, but has sparked community controversy due to its complexity and increased attack surface. Most users holding a large amount of ETH opposed it in the voting.
