Ethereum’s Fusaka hard fork is expected in late 2025, and Ethereum core developer Tim Beiko has ruled out the inclusion of the controversial EVM Object Format (EOF) upgrade.
Update (April 28, 10:26 pm UTC): This article has been updated to add commentary from Tim Beiko that the EOF upgrade was removed from the Fusaka upgrade.
Ethereum’s Fusaka hard fork is expected to take place in the third or fourth quarter of this year, according to an Ethereum Foundation official.
