The highly anticipated Dencun upgrade, featuring the significant “proto-danksharding” update aimed at reducing layer-2 transaction fees, has been successfully deployed on Ethereum’s Goerli testnet. However, the upgrade faced challenges, with low participation leading to a failure to be finalized within the expected timeframe.
The Dencun upgrade officially went live on the Goerli testnet on January 17, as confirmed by Tim Beiko, the community manager at Ethereum Foundation. Beiko acknowledged the suboptimal participation among validators, highlighting that such an outcome was anticipated. The upgrade process also resulted in a “chain split” due to a lack of synchronization among all validators.
Following its implementation on Goerli, the next stages of the Dencun upgrade are scheduled for January 31 on the Sepolia testnet and February 7 on the Holesky testnet. Successful implementation on all three testnets is a prerequisite for the Ethereum Foundation’s plan to roll out the Dencun upgrade on the Ethereum mainnet by the end of Q1 2024.
Dencun, represented by Ethereum Improvement Proposal 4844 (EIP-4844), aims to enhance blockchain space for data blobs, with the activation of proto-danksharding intended to reduce layer-2 rollup fees. The expansion of data storage capacity is expected to contribute to the scalability of Ethereum’s blockchain, allowing for increased transaction capacity without a corresponding rise in gas fees.
It is noteworthy that Dencun marks the final upgrade for the Goerli testnet. After the completion of the Dencun upgrade, both the client and Ethereum Foundation testing teams will cease support for the Goerli testnet.
