during the recent All core developers run (ACDE) will hold a conference call chaired by Tim Beiko of the Ethereum Foundation on Feb. 2 where contributors will discuss the timeline for the public testnet launch of the Shaingahi upgrade, which will bring the ability to destake ETH from the Beacon chain. rice field.
The first iteration of the Shanghai upgrade was deployed to testnet on February 1st called Zhejiang and endorsed by 61,000 validators.
However, Barnabus Busa, a DevOps engineer at the Ethereum Foundation, said the testnet was struggling to process new deposits of staked ETH, possibly due to a configuration issue in the CL software client. I am commenting. galaxy Report on calls.
This issue has been fixed and will be deployed in Zhejiang on February 7th.
A roadmap for future testnet deployments of the Shanghai upgrade will be confirmed at the next All Core Developers Execution Consensus (ACDC) call scheduled for February 9th. Beiko emphasized:
Ethereum client teams should be prepared to cut releases for the launch of the Seporia Shanghai testnet next Thursday, shortly after the ACDC call.
Seporia deployment in Shanghai is expected to start in mid-February, and the developer confirmed in a phone call that it is “ready to move forward.”
Regarding the decision to deploy to Sepolia before Goerli, ACDC Call Chairman Danny Ryan said:
I think it makes sense to run Sepolia before Goerli, given that Goerli is used by more validators than a limited set. It gives us a little more time to be robust.
As long as the testnet rollout is successful, the Shanghai mainnet launch is scheduled for mid-March.
As the implementation of EIP-4844 draws nearer, Cancun, the next update slated for deployment, was also discussed.
EIP-4844 Adds Proto-Danksharding to the Ethereum Blockchain, Introducing Data Blobs as the First Milestone Toward Full Ethereum Sharding and 100x Capacity Expansion for Optimism-Like Rollups make it possible. according to Ethereum Researcher Diederik Loerakker of OP Labs.
ethereum developer website EIP-4844 expert describes benefits of upgrade: better rollup, lower charges, lower disk usage, blobs residing in beacon nodes instead of execution layer, and blob pruning every two weeks. bottom.
On the ACDE conference call, imapp’s Jacek Glen commented that testing EIP-4844 had shown a “significant difference” in gas prices and had not created any significant development impediment issues. As a result, ACDE has agreed to go ahead and review the test at a later date.
Developers continued to discuss the implementation of “blob” and whether to allow access to the mempool. However, Ethereum Nethermind developer ukasz Rozmej commented that zero blob transactions could be a problem.
There are also question marks on UX, user experience and usability in general, because marking these transactions as BLOB transactions gets special treatment because they have a special domain in my opinion.
If we allow zero blob transactions, this reasoning is broken and we also need to look at the number of blobs for this transaction rule. “
Ansgar Dietrichs also published his research decoupling Block blob generation by creating sub-networks for propagation. This proposal aims to reduce Ethereum client bandwidth while adding production for Bob.
Ethereum co-founder Vitalik Buterin suggestion Five new SSZ transaction types to help maintain backward compatibility as networks are upgraded to EIP-4844 and other new data types. Simple serialization (SSZ) is the serialization method used throughout the beacon chain that replaces the RLP method used in the execution layer. Vitalik’s proposal aims to “do it all at once to avoid the extra cost of designing multi-step migrations.” The new proposed types are:
SSZ-style conversations were put on hold as Ethereum Nimbus developer Etan Kissling raised a question on SSZ Feb 7 regarding the EIP-4844 code change.
