Developers Implement Crucial Fix After Ethereum’s Pectra Upgrade Faced Issues on Sepolia Testnet

The planned upgrade of Ethereum Pectra, the most important blockchain update since “The Merge” of 2022, launched today on the Sepolia Testnet. However, the launch was not fluid because it was faced with problems in its Testnet version, further delaying the launch of Mainnet. According to a recent tweet of the main Ethereum developer, the team identified the problem and deployed a fix.

Quick correction applied to the problem of the Sepolia deposit contract

The Ethereum community uses reception tests to experiment with important updates in a secure environment before being implemented on primary blockchain, often called “Mainnet”.

Despite these precautions, the deployment has encountered clocks. Tim Beiko, a leading developer of the Ethereum Foundation, reported on Twitter that they addressed a problem linked to the personalized deposit contract on the testnet of Sepolia.

He also explained that this problem had had an impact on certain customers of the execution layer (EL), leading to problems of transaction processing in the blocks. EL customers are essential software that operates on the nodes of the Ethereum network.

About six hours after identifying the error, Tim Beiko reported that a solution was in place. He said: “The customer teams have coordinated on a fix and try to deploy it to the validators now. If it works as expected, we will have a longer update shortly. »»

Tim Beiko said all node operators must upgrade their nodes to the versions listed on the Ethereum website blog. He mentioned that the validators had already upgraded, which made it possible to operate normally to the chain. However, he noted that explorers, portfolios and other infrastructure providers could encounter problems until they also upgrade.

The Mainnet version could be delayed

Earlier in the day, the launch was praised as a triumphant success. Terence, one of the main developers Ethereum, shared on Twitter that the Pectra had “finalized with a perfect proposal rate” on the Sépolia Testnet. This meant that each validator had perfectly proposed its blocks allocated without fault.

However, this achievement came after a difficult period. Initially, the deployment of Pectra on Sepolia had caused significant disturbances, preventing transactions from being recorded and would essentially put the testnet for an internship for about five hours.

Pectra upgrade had already encountered problems. For example, a configuration error among the validators caused a chain split when it was deployed on the Holesky Testnet on February 24, which failed. Ethereum developers are now expecting it to take at least two more weeks to finalize this activation.

The plans for a main launch of Pectra, which is one of the most important forks since Ethereum has moved to proof of assistance, depends on the successful upgrades of Holesky and Sepolia tests.

Although the Ethereum Foundation initially targeted a version in early April for the Mainnet, this calendar could be stretched to guarantee that the problems observed in time tests are carefully treated and do not reproduce.
