TechFlow reported, Galaxy Research Vice President Christine Kim summarized the 172nd Ethereum Core Developers' Execution (ACDE) call, during which developers discussed Cancun and Deneb (Dencun) testing as well as Ethereum Virtual Machine (EVM) Object Format (EOF) development. Details are as follows:
Devnet #9 update (launched September 29): Devnet #9 currently has a participation rate of 93%. The 7% of validators not running are primarily composed of Geth (EL)/Teku (CL) validator nodes. Issues also exist with the Erigon (EL)/Prysm (CL) client combination and the EthereumJS (EL) client. The Flashbots team is testing MEV-Boost relays and builders on Devnet #9. Blob transactions have not yet been tested through MEV-Boost builders.
Devnet #10 will not be ready this week but may be available next week. Developers hope to test trusted setup files from the EIP-4844 KZG ceremony. Devnet #10 will feature a large validator set, including 330,000 active validators. At the launch of the devnet, there will be a surge in validator deposits and withdrawals, triggering the validator churn limit to change from 5 to 4 within approximately one to two days after network startup.
EVM Object Format (EOF) development: Currently, four main teams are working on EOF development—Team Ipsilon funded by the Ethereum Foundation, EL client teams (e.g., Geth, Besu, and Nethermind), advanced language compiler teams (e.g., Solidity and Vyper), and smart contract developers. EOF requires creating a new container format for EVM code while maintaining backward compatibility with the current format.
Several developers, including Tim Beiko, expressed hesitation about the proposed three-to-six-month timeline for EOF implementation following the Dencun upgrade. Developers are also considering including another major code change, Verkle, in Prague/Electra.
