Ethereum core developers discuss the timeline for the Shanghai upgrade testnet and the progress of EIP-4844

ChainCatcher message, Ethereum core developers discussed the timeline for the Shanghai upgrade public testnet release and the progress of the Cancun upgrade (the upgrade after the Shanghai upgrade) focused on EIP-4844 during the call #154 on February 2.

It is reported that the Ethereum public withdrawal testnet Zhejiang went live on February 1, allowing anyone to request testnet ETH from the faucet and launch their own validators on the network. The Zhejiang testnet currently has 61,000 active validators supporting it, most of which are operated by the Ethereum Foundation.

Due to potential configuration issues with the CL software client, the testnet is working to handle new staked ETH deposits. Assuming this issue is resolved in the coming days, developers plan to activate the Shanghai upgrade on the Zhejiang testnet on February 7.

If the Shanghai upgrade proceeds smoothly on the Zhejiang testnet, developers will decide on the activation date during the ACDC call on February 9 to release the upgrade on the Sepolia testnet. Developers plan to release the Shanghai upgrade on the Ethereum Goerli testnet by the end of February or early March, and after a successful transition, will turn to the mainnet.

Ethereum core developers also spent most of the time discussing matters related to EIP-4844, including gas pricing, transaction validity rules, transaction pool testing, and coupling with blob/block. (source link)
