Ethereum Devs Prep For Devnet-9

Ethereum developers convened for the 118th All Core Developers Consensus (ACDC) call. Led by Danny Ryan, a researcher associated with the Ethereum Foundation, these ACDC calls, held bi-weekly, serve as a collaborative platform for Ethereum developers to discuss and coordinate changes to the consensus layer (CL) of the Ethereum network. During this week’s call, which lasted approximately 30 minutes, the primary focus was on the preparations for Devnet-9 and discussions surrounding the forthcoming Cancun/Deneb (Dencun) upgrade.

Devnet-9 Readiness

Devnet-9, poised to become the second testnet showcasing the complete suite of code changes intended for the Cancun/Deneb upgrade, took center stage. Unlike its predecessors that were primarily dedicated to testing Ethereum Improvement Proposal (EIP) 4844, Devnet-9 will be the first to incorporate the activation of two recently added EIPs, namely 7514 and 7516, introduced during a prior ACDC call. Parithosh Jayanthi, a DevOps Engineer at the Ethereum Foundation, announced that the Devnet-9 launch is scheduled for September 27. Several Execution Layer (EL) and CL client teams, including Lodestar, EthereumJS, Lighthouse, and Geth, have committed to being prepared for the deployment.

While certain client teams such as Besu and Nethermind are presently engaged in conducting Hive tests on their Devnet-9 releases, Jayanthi underscored the possibility of proceeding with the launch even if not all clients are immediately prepared. The call also drew attention to issues concerning Dencun-related tests, prompting developers to issue a prompt fix to address malfunctioning tests within the “consensus-spec-tests” code repository. Furthermore, discussions centered on potential adjustments to an endpoint known as “blockv3,” a critical component in block production between validator clients and beacon nodes.


Goerli Testnet

Developers devoted time to strategizing the deployment of EIP 4788, which will be executed as a regular smart contract, necessitating a contract address for client implementations to reference during the activation of the code change. Although the contract address’s finalization is pending, developers stand ready to update their releases with this information following the genesis of Devnet-9.

Additionally, discussions revolved around the deployment of a trusted setup for EIP 4844 on Devnet-9, entailing the transformation of results from a multi-party ceremony into a standardized format suitable for implementation on Ethereum testnets and the mainnet. Regarding the timeline for Dencun, developers explored the possibility of launching it on public testnets like Goerli and Holesky prior to mainnet activation, with a particular emphasis on Goerli as a deprecated yet suitable testnet for experimenting with specification changes.
