According to a report from “The Block”, Ethereum core developers have deployed the Dencun hard fork upgrade on the Goerli test network, which includes the important Ethereum Improvement Proposal EIP-4844 (Proto-danksharding).
During a live broadcast, core developers confirmed that the Dencun upgrade was forked on the Goerli test network at around 2:35 pm on Wednesday (17th) Taiwan time. However, this upgrade faced some obstacles, including potential “chain splits” due to synchronization issues between clients, and it is expected that the client teams will investigate this issue and release a fix. The network is currently awaiting finality.
During critical upgrade periods, client issues often occur on test networks, and client teams typically resolve synchronization errors before upgrading the main network.
To prepare for this transition, the development team chose a phased approach – first implementing the upgrade on different test networks. Following today’s deployment on the Goerli test network, the next implementation steps include launching Dencun on the Sepolia test network on January 31, upgrading on the Holesky test network on February 7, and the final main network upgrade is expected to be implemented at the end of the first quarter of 2024.
The core focus of this Dencun deployment is the introduction of the 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. This is expected to significantly reduce transaction costs for Ethereum dApps, especially benefiting Layer 2 networks.
