During the recent All Core Developers Execution (ACDE) call on Feb.2, chaired by Tim Beiko of the Ethereum Foundation, contributors discussed the timeline for the public testnet launch of the Shaingahi upgrade, which will bring with it the ability to unstake ETH from the Beacon chain.
Zhejiang Testnet Launch
The first iteration of the Shanghai upgrade was deployed to a testnet on Feb. 1 — dubbed Zhejiang, and backed by 61,000 validators.
However, Barnabus Busa, a DevOps engineer at the Ethereum Foundation, commented that “the testnet was struggling to process new deposits of staked ETH due to what may be a configuration issue with the CL software clients,” according to a Galaxy report on the call.
The issue is expected to be fixed and deployed to Zhejiang on Feb. 7.
The roadmap for future testnet deployments of the Shanghai upgrade will be confirmed on the next All Core Developers Execution Consensus (ACDC) call scheduled for Feb. 9. Beiko stressed that:
“Ethereum client teams should prepare to cut releases for the Sepolia Shanghai testnet launch shortly after next Thursday’s ACDC call.”
The Sepolia deployment of Shanghai is expected to launch in mid-February, with developers confirming on the call that they are “ready to move forward.”
Regarding the decision to deploy to Sepolia before Goerli, the chair of the ACDC calls, Danny Ryan, said,
“I think it makes sense to do Sepolia before Goerli given that Goerli is used by much more validators outside of a limited set and so that gives a bit more time for documentation and tooling to become more robust.”
A mainnet launch for Shanghai is scheduled for mid-March as long as the testnet deployments succeed.
EIP-4844
The next update scheduled for deployment, Cancun, was also discussed as the implementation of EIP-4844 comes closer.
EIP-4844 will add Proto-Danksharding to the Etherum blockchain introducing blobs of data as the “first milestone towards full Ethereum sharding, enabling rollups like Optimism to…
