According to BlockBeats, on February 16, Christine Kim, vice president of Galaxy Research, summarized the 181st Ethereum Core Developer Execution (ACDE) conference call. Developers shared their latest preparations for the mainnet activation of the Dencun upgrade and discussed various Ethereum Improvement Proposals (EIPs). Most of them are proposed to be included in the Pectra upgrade, while others are proposed as "retroactive" EIPs, which means that changes to the protocol rules will be retroactively applied to all Ethereum transactions since the genesis. Barnabas Busa, development and operation engineer of the Ethereum Foundation, said that his team is synchronizing nodes to the Ethereum mainnet in preparation for the shadow fork. Developers plan to perform a shadow fork of the Ethereum mainnet for the Dencun upgrade after the final client version of all Dencun is released. The client team plans to release the final version of Dencun later next week. Busa said that his team will upgrade their nodes to these versions shortly thereafter and plans to complete the mainnet shadow fork by Friday, February 23. Once the results of the shadow fork are in, and the results are positive, he will proceed to publish an official EF blog post announcing the mainnet activation date for the Dencun upgrade as March 13th.
