- Ethereum developers excluded EIP 7907 from the Fusaka upgrade to preserve smart contract code size limits and network stability.

- The decision reflects historical caution, deferring complex changes to the Glamsterdam fork while prioritizing implementation readiness.

- Fusaka's phased testnet rollout (August-October) and planned Devnet-3 launch (July 23) emphasize rigorous pre-mainnet testing.

- Ongoing Glamsterdam discussions focus on proposer-builder separation and block-level access lists, with final code changes expected in 2-4 weeks.

Ethereum developers have decided to maintain the current smart contract code size limits, opting to exclude EIP 7907 from the upcoming Fusaka upgrade. This decision was made during the 216th Ethereum Execution Layer Core Developer Meeting, where it was confirmed that the smart contract code size limits would remain unchanged. The exclusion of EIP 7907 was driven by concerns over complexity and potential timeline risks associated with its implementation. This move ensures that the current smart contract conditions on Ethereum will remain stable, retaining deployment conditions on the mainnet. No immediate market changes are expected as these adjustments are primarily technical.

Historical trends show that Ethereum has postponed EIPs in upgrades when concerns arose about implementation readiness. Stable smart contract conditions reassured developers, with further discussions deferred to the Glamsterdam fork. Stakeholder decisions underscore Ethereum’s iterative, safety-first evolution strategy, supported by historical precedents of similar decisions delaying code changes without market disruption. The developer community maintains a cautious approach, ensuring Ethereum protocol's evolving landscape aligns with stability and consensus-driven enhancements.

The decision to remove EIP 7907 from the Fusaka upgrade reflects the developers' commitment to maintaining the stability and security of the Ethereum network. By prioritizing the current code size limit, they aim to avoid potential disruptions that could arise from implementing complex changes. This cautious approach is essential for ensuring the smooth operation of the network and the continued trust of its users.

Ask Aime: How will Ethereum's decision to exclude EIP 7907 from the Fusaka upgrade impact the current smart contract code size limits?

The proposed timeline for the Fusaka upgrade demonstrates the developers' meticulous planning and dedication to a thorough testing process. The client public testnet release is scheduled for the week of August 25, followed by the first public testnet upgrade between September 22 and October 3. A second testnet upgrade is planned for October 6 to 10. Additionally, developers are set to launch Fusaka Devnet-3 on July 23. These steps are crucial in preparing the network for the mainnet launch of Fusaka.

Regarding the Glamsterdam hard fork, developers have reached a general consensus on the planned implementations. However, several key issues, such as the "proposer-builder separation solidification mechanism" and the "block-level access list," are still under discussion. After further consultation with the broader Ethereum community, developers aim to finalize the core code changes for the Glamsterdam upgrade within the next two to four weeks. This collaborative approach ensures that the community's input is considered, fostering a more inclusive and robust development process.

The ongoing discussions surrounding the Glamsterdam hard fork highlight the collaborative nature of the Ethereum development process. By involving the broader community in decision-making, developers can address concerns and incorporate valuable feedback. This inclusive approach is essential for the continued growth and success of the Ethereum network, as it ensures that the community's needs and expectations are met.
