According to The Block, Ethereum core developers deployed the Dencun upgrade on the Holesky testnet on Wednesday, marking the final Ethereum testnet upgrade before the mainnet deployment expected next month.
Prior to this, the Dencun upgrade was phasedly deployed on the Goerli testnet on January 17th and the Sepolia testnet on January 30th. Now, the mainnet deployment date for Dencun is expected to be confirmed during tomorrow’s Ethereum core developers’ conference call. The upgrade is expected to take place between early March and mid-March.
The core focus of this Dencun deployment is the introduction of Ethereum Improvement Proposal EIP-4844, a new transaction mechanism known as “temporary blobs” or “proto-danksharding.” It allows Ethereum nodes to temporarily store and access off-chain data to reduce storage requirements. This is expected to significantly lower transaction costs for Ethereum dApps, particularly benefiting Layer 2 networks.
