According to a report from “The Block”, Ethereum core developers deployed the Dencun upgrade on the Holesky testnet on Wednesday (7th), marking the final Ethereum testnet upgrade before the expected mainnet deployment next month.
Prior to this, the Dencun upgrade was deployed in stages on the Goerli testnet on January 17th and on the Sepolia testnet on January 30th. The mainnet deployment date for Dencun is expected to be confirmed at tomorrow’s Ethereum all-core developers’ call. The upgrade is expected to take place between early March and mid-March.
The key point of this Dencun deployment is the introduction of Ethereum Improvement Proposal EIP-4844 – a new transaction mechanism known as “temporary blobs” or “proto-danksharding”, which allows Ethereum nodes to temporarily store and access off-chain data to reduce storage requirements. It is expected that this will significantly reduce transaction costs for Ethereum dApps, especially benefiting Layer 2 networks.
