Problem Discovered in Ethereum! Ethereum’s new upgrade, Dencun, was scheduled to go live on the Goerli testnet on January 17. However, at the scheduled time for the upgrade to go live, Tim Beiko announced that the fork had occurred. However, in a post he made 20 minutes later, he noted that a chain split had occurred due to the operation being unable to be completed.

It had previously been announced that the Dencun upgrade had goals such as reducing transaction costs on layer-2 networks, preventing self-destruct transactions, and bringing various features such as new bridges and staking pools.
The necessary preparations had been completed for the upgrade to go live, and the upgrade was about to go live. However, a chain split occurred due to the operation being unable to be completed. This delayed the upgrade from going live by four hours.
The goerli fork finalized! 😀https://t.co/LIa3d4Ml5H
After the fix was patched in, the validators came back online and the chain started finalizing again. The MEV circuitbreaker automatically disables and mev-blocks have started flowing through as well.

Parithosh Jayanthi emphasized that the quick implementation of the solution once again showed the strength of the team’s debugging systems. The developer underlined that the entire process of Fork -> problem -> prioritization -> correction -> termination took four hours and stated that the new debugging system was great.
It is expected that the problem will be fixed and the version will be implemented by the end of the month.
The next stage of Dencun’s test program will be the upgrade that will be carried out on the Sepolia testnet on January 30. The next test will be seen on the Holesky network on February 7. The Ethereum developer team has not yet announced when Dencun will go live on the main network.
