Highlights of Ethereum Devs Call

In the ACDC (All Core Developers Consensus) meeting held on October 19, 2023, Ethereum developers discussed several important topics related to Ethereum's consensus layer and upcoming upgrades. Here's a summary of the key points discussed in the meeting:
The Summoning - CL Specifications Update:
Ethereum Foundation Researcher Danny Ryan announced the release of new CL (CasperLabs) code specifications for the Cancun/Deneb upgrade, referred to as "The Summoning."
This update, tagged as version 1.4.0-beta.3, introduced two main changes:
Finalization of the Mainnet KZG configurations.
A new gossip rule to prevent nodes from propagating more than six blobs per block, preventing network spam.

Devnet-10 Launch:

The changes in CL specifications (1.4.0-beta.3) will be tested on Devnet-10, the next development network.
However, there were some blockers to the launch of Devnet-10, including waiting for new software releases from client teams.
There were concerns about the integration of Mainnet KZG configurations into client software, particularly related to "go-kzg."

Issues on Devnet-9:

Developers identified issues on Devnet-9, where validators were not correctly pruning invalid blobs, potentially causing network synchronization problems.
Teku client was mentioned as not importing a block under certain conditions if the block contained invalid blobs.
To address this, developers discussed potentially adding a new slashing condition to dissuade validators from intentionally causing strain on the peer-to-peer network.

Block Latency Analysis:

Gajinder Singh, a maintainer of Ethereum clients Lodestar and EthereumJS, shared an analysis on block import latency based on the number of blobs gossiped.
The analysis showed that higher numbers of blobs introduced significant latency.
However, there was some disagreement about the accuracy of these findings, and it was suggested that another client team replicate the experiment.

Future Discussions:

There was a discussion about the potential addition of a new slashing condition to address issues related to invalid blobs, but it was suggested that this should be considered for a future upgrade after Dencun.
The meeting concluded with a call for further testing and discussion on block latencies with the introduction of blobs.

Overall, the meeting primarily focused on technical updates, testing, and potential solutions to issues related to Devnet-10 and block propagation on the Ethereum network. There were also discussions about future upgrades and their impact on Ethereum's consensus layer.
