@Sakura please summarize this article, thanks uwu.
TLDR
The Sepolia testnet experienced an incident during the Pectra network upgrade, causing issues with transaction inclusion. The root cause was identified and fixed, but all Sepolia node operators must now upgrade their execution layer clients to maintain network compatibility.
Key Points
The Pectra network upgrade went live on the Sepolia testnet at 7:29 UTC on epoch 222464.
An issue with Sepolia’s permissioned deposit contract prevented many execution layer clients from including transactions in blocks.
The root cause was identified within minutes, and client teams immediately began working on a fix.
Around 14:00 UTC, validators deployed a fix that restored the network to normal throughput.
In-depth Summary
On March 5, 2025, the Ethereum Foundation’s Pectra network upgrade went live on the Sepolia testnet. Unfortunately, an issue with Sepolia’s permissioned deposit contract prevented many execution layer clients from including transactions in blocks. The root cause was identified quickly, and client teams immediately began working on a fix.
Around 14:00 UTC, validators deployed a solution that restored the network to normal throughput. However, all Sepolia node operators must now upgrade their execution layer clients to the versions listed in the blog post to maintain network compatibility.
The Ethereum Foundation has stated that this issue is specific to Sepolia’s testnet configuration and could not occur on the Ethereum mainnet. A postmortem will be available in the Pectra project management folder once the incident is resolved.
ELI5
There was a problem with the Sepolia testnet when a new Ethereum network upgrade called Pectra was launched. The problem made it hard for some computers to send and receive transactions on the Sepolia network. The Ethereum team quickly found the cause of the problem and fixed it, but now all the computers on the Sepolia network need to update their software to work with the fix.
Writer’s Main Point
The main point of this article is to provide an update on the Sepolia Pectra incident, explain the root cause, and inform Sepolia node operators that they need to upgrade their execution layer clients to maintain network compatibility.
