Dencun Update is Deployed on Ethereum Testnet Sepolia

Reading Time: < 1 minute

The Dencun (Deneb-Cancun) hard fork has been successfully implemented by Ethereum developers on the Sepolia test network.

Lead developer Terence Cao announced the completion of the update on January 17, following a chain split caused by a previous upgrade on the Goerli testnet.

The upgrade includes EIP-4844, which introduces the Proto-Danksharding option to improve network scalability by creating a new transaction type for large binary data sets (BLOBs). This is expected to significantly decrease fees for second layer (L2) solutions based on Rollups technology.

Parithosh Jayanti from the Ethereum Foundation commented on the successful fork, stating that “massifs flow into Sepolia,” highlighting the convenience and success of the update. The next planned deployment of the upgrade is on the third testnet, Holesky, on February 7.

After this, the developers will determine the date for the hard fork to be implemented on the main network. It is worth noting that the previous Ethereum upgrade, Shapella (Shanghai-Capella), was implemented on April 13, 2023. This upgrade allowed validators to withdraw ETH from staking.
