Ethereum removes EOF from Fusaka upgrade following community objections.

Ethereum developers have formally decided to exclude the EVM Object Format (EOF) from the forthcoming Fusaka network upgrade, attributing this move to uncertainties in the technology and resistance from the community.

Tim Beiko, the Protocol Support Lead at the Ethereum Foundation, confirmed that this decision was reached during the Ethereum All Core Developers (ACD) meeting on April 28.

This announcement followed earlier comments from Tomasz Stańczak, co-executive director at the Ethereum Foundation, who had previously stated that EOF would be included in the Fusaka upgrade planned for late 2025.

However, significant objections from the Ethereum community led to a reassessment of its role in the upgrade. Detractors claimed that EOF introduced unnecessary complexity to the blockchain network.

EOF represents a proposed transformation of the Ethereum Virtual Machine (EVM). This upgrade includes multiple Ethereum Improvement Proposals (EIPs) designed to simplify and enhance smart contract development, making it more efficient and user-friendly.

### Reasons for the Delay of EOF

Beiko noted that the main reason for EOF’s exclusion from Fusaka was to ensure the upgrade remained on schedule.

He stressed that all client teams agreed on the need to prioritize PeerDAS, another key feature in Fusaka, which aims to improve Ethereum’s scalability and data accessibility.

Beiko mentioned that ongoing disagreements over various iterations of EOF complicated coordination efforts. He pointed out that these unresolved discussions were obstructing the development process.

The Ethereum Foundation executive also highlighted a larger concern regarding the prioritization of proposals within the ACD framework. Many developers did not fully grasp the consequences of the specific EOF variant they were advocating. This lack of clarity should have been addressed sooner in the proposal process, he indicated.

He remarked:

“There appeared to be general support during the call for the Option D variant, but at one point, some participants acknowledged that they didn’t comprehend the implications of this variant.”

Given these factors, Beiko concluded:

“It appears appropriate to remove EOF from Fusaka while allowing its proponents to make a case for it in Glamsterdam, where the focus can hopefully shift to identifying the most impactful changes for Ethereum as a whole.”
