Ethereum Developer Conference: Pectra upgrade encounters new bug, public testnet upgrade postponed

ChainCatcher news, Ethereum developers stated in the 204th Core Developer Execution Layer meeting (ACDE) that due to a new consensus bug in Pectra Devnet 5 affecting the Nethermind client, the developers decided to postpone the determination of the specific upgrade time for the public testnet.

The Nethermind team stated that the bug caused by BLS precompile optimization has been fixed and will not affect the launch of Devnet 6. Developers plan to revisit the testnet upgrade timing in next week's ACD meeting. Additionally, the meeting discussed a security vulnerability affecting the Geth client, which could impact Ethereum's peer-to-peer layer and Layer-2 scaling solutions. Nodes running Geth version 1.14 and above need to update to the latest version immediately.

The Pectra upgrade schedule is as follows:

• Week of February 3: Launch Devnet 6;
• February 6 (Thursday): Next ACD meeting to decide on the upgrade timing for Holesky and Sepolia testnets;
• February 10-11 (Monday or Tuesday): Official announcement of the testnet upgrade;
• Around February 19: Holesky testnet upgrade;
• February 20: Developer meeting to decide on Ethereum mainnet upgrade timing;
• Around February 26: Sepolia testnet upgrade (planned about a week after Holesky upgrade);
• February 27-28: Release final version of mainnet upgrade;
• Mid-March: Ethereum mainnet upgrade.
