Dencun upgrade has been successfully deployed on the Sepolia testnet. This deployment, the second of three planned testnet releases, brings Ethereum closer to implementing the significant improvements of the upgrade.
The deployment on Jan. 30 proceeded smoothly, receiving positive feedback from key participants in the Ethereum ecosystem. Terence Tsao, from Prysmatic Labs, the team behind the Prysm Ethereum client, tweeted that "Sepolia has finalized," indicating a satisfactory and uneventful upgrade.
The fork follows a somewhat rocky initial dress rehearsal on the Goerli testnet on Jan. 17. The Goerli fork triggered a network split resulting from a bug encountered by the Prysm client. Developers rectified the incident several hours after the fork's initiation.
Dencun final testnet deployment will take place on Ethereum’s Holesky testnet come Feb. 7.
Dencun will significantly improve data availability and reduce the fees associated with transacting on Layer 2 by replacing gas-intensive calldata with blobs via the EIP-4844 upgrade, also dubbed proto-danksharding.
