Despite discovering a bug in the latest Shanghai release for the Geth EL client, Ethereum developers have agreed to continue rolling out the Shanghai upgrade on the Sepolia test network later this month.
The bug was discovered on February 16 during the All Core Developers Execution (ACDE) call #155, led by the Ethereum Foundation’s Tim Beiko. The bug affects the Geth EL client and was discovered during testing on the Zhejiang test network.
Ethereum Developers to Implement Changes to the Protocol
The Geth client (EL) team has since issued a fix for the bug, which caused nodes to fail to download and initialize blocks without withdrawals and transactions.
During the ACDE call, representatives of the Nethermind and Erigon (EL) client team confirmed that they would double-check the empty block handling logic in their latest release to ensure that they are not susceptible to the same bug. Additionally, the developers agreed to exclude zero blob transactions from the Ethereum mempool and protocol.
The developers discussed how the protocol and mempool should handle transactions formatted as blobs that do not contain any data and finally agreed to disallow blob zero transactions from the protocol in their implementation of EIP 4844 for the Cancun upgrade.
Despite these issues, the developer is committed to rolling out the Shanghai upgrade on the Sepolia test network on February 28. In order to achieve this, the client team must stop new releases for Shanghai early next week, and all client teams have confirmed they can do so.
Furthermore, the developer will begin testing the MEV-Boost software circuit breaker mechanism in the coming weeks. Additionally, the Ethereum Nimbus (CL) client team is making progress in updating the Ethereum EL block header to the SSZ format, with two main approaches currently under consideration.
However, the Ethereum protocol is constantly evolving, and its developers are working hard to make it better. While bugs and issues are expected along the way, the developer remains committed to moving forward and delivering the Shanghai and Cancun upgrades, which are critical to Ethereum’s continued success.
