Ethereum Devnet #12 has activated Cancun/Deneb upgrade

Christine Kim, Vice President of Galaxy Research, summarized the 123rd Ethereum Core Developer Consensus (ACDC) conference call. The Cancun/Deneb upgrade was activated on Devnet #12 on November 30th, and the Teku, Lodestar, and Lighthouse client software, as well as all Execution Layer (EL) client software, are currently being tested on Devnet #12. In addition, developers found validator exit issues on Devnet #11, and the Nimbus client team is working to resolve the issue. Devnet #11 will continue to operate normally until the problem is resolved.

Given that the CL client Prysm has not yet joined Devnet #12, developers have agreed to postpone the planned Goerli shadow fork until the Prysm client software is ready for testing. Tim Beiko suggested launching the Goerli shadow fork at some point before the end of this year.

In addition, developers discussed the specification for clarifying BlockByRoot and BlobSidecarsByRoot requests to explicitly mention whether CL nodes should respond to these requests in a specific order.
