TechFlow reports, Christine Kim, VP of Research at Galaxy, summarized the 121st Ethereum core developer consensus call: Developers discussed significant changes to Ethereum's consensus layer (CL), including modifications to the Cancun/Deneb specifications to simplify Blob implementation, updates to upgrade specifications, validator reorganization regarding later blocks, updates on testnet timelines, and the creation of JSON mappings for CL SSZ specifications.
According to the meeting, Devnet 11 is now live and operational; Goerli shadow fork has started today to assess block and blob propagation delays; Devnet 12 may not launch until early December. Kim believes developers may begin upgrading the Goerli public Ethereum testnet after the holiday season in Q1 2024.
