Christine Kim, Vice President of Research at Galaxy, published a document summarizing the 120th Ethereum Core Developer Consensus (ACDE) conference call, where developers discussed and coordinated changes to the Ethereum Consensus Layer (CL). This week, developers discussed CL specification version 1.4.0-beta.3, launch conditions for Devnet-10, and blob latency analysis by Gajinder Singh, a software developer who maintains Lodestar and EthereumJS clients.
- Regarding the new CL code specification for the Dencun upgrade, the specification is named "The Summoning". The version is officially marked as version 1.4.0-beta.3 in the CL GitHub repository. The main changes include the mainnet KZG configuration (complete Ethereum The formatting work required for the FangTrust setup ceremony output has been completed and included in the latest CL specification version) as well as new gossip rules (to ensure that the number of blobs propagated by CL nodes does not exceed the maximum number of blobs per block, This is currently defined in the specification as 6 blobs per block, which will ensure that validators cannot spam the network);
- Regarding Devnet-10, the changes in the CL specification 1.4.0-beta.3 version will be tested on Devnet-10, there are some obstacles in the rollout of Devnet-10, waiting for the client team to release the new software, once it is ready, hopefully Devnet-10 will be launched sometime on October 20th (not launched as of yet). An anonymous developer pointed out that the mainnet KZG configuration included in the latest CL specification cannot be merged into Geth and Prysm unless changes are made to "Go - KZG" to implement the KZG commitment scheme into the Go programming language and on Devnet-9 The problem of "the validator did not reduce invalid blobs correctly" was found in the CL client implementation. Some developers believe that the above two problems should be solved before launching Devnet-10. Ethereum Foundation researcher Danny Ryan believes that the new reduction conditions The discussion only applies to Prague/Electra upgrades and not Dencun upgrades, and changes to the CL specification for importing blocks with invalid blobs should not be a barrier to Devnet-10 launch.
- Representatives from Prysm and Lighthouse account teams said they will release updated versions of their software by October 20. Regarding blob latency analysis, from Gajinder Singh’s experiments on Devnet-9, the larger the number of blobs received by the validator, the delay of the block will increase significantly. Ryan encouraged another CL team to try to reproduce Singh's experiment on Devnet-9 to see if they could get similar values and results.
