The core team of Ethereum has successfully activated the Dencun (Cancun-Deneb) upgrade in the Goerli test network, implementing EIP-4844. However, the hard fork completion plan was not executed on schedule.
This upgrade includes the Proto-Danksharding option, designed to scale the network by introducing a new type of transaction for handling large binary data arrays (BLOB). It is expected to reduce transaction fee costs for L2 solutions based on Rollup technology.
The lead developer, Tim Beiko, noted that "BLOB objects are coming in," although most of them turned out to be empty.
The full completion of the upgrade was unsuccessful, likely due to about a fifth of client operators not updating their software (there were several of them).
According to his estimate, completing the work may take several days.
According to the preliminary schedule, the deployment of the Dencun upgrade in the Sepolia test network is planned for January 30th, and on February 7th, it is scheduled for the Holesky network. It is expected that by the end of February, the team plans to conduct a hard fork in the main network.
The construction of the initially planned upgrade for the fourth quarter of 2023 was postponed by developers due to ongoing consensus issues.
