According to The Block’s report, Ethereum core developers have deployed the Dencun hard fork upgrade on the Goerli testnet, which includes the important Ethereum Improvement Proposal EIP-4844 (Proto-danksharding).
During a live stream, core developers confirmed that the Dencun upgrade was forked on the Goerli testnet at around 2:35 PM Taiwan time on Wednesday (17th). However, this upgrade has encountered some obstacles, including potential “chain splits” due to synchronization issues between clients. The client teams are expected to investigate this issue and release a fix. The network is currently awaiting finality.
During critical upgrade periods, client issues often occur on the testnet. Typically, client teams resolve synchronization errors before upgrading the mainnet.
To prepare for this transition, the development team has chosen a phased approach – first implementing the upgrade on different testnets. After today’s deployment on the Goerli testnet, the next steps include launching Dencun on the Sepolia testnet on January 31st, followed by an upgrade on the Holesky testnet on February 7th. The final mainnet upgrade is expected to be implemented in 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”. This mechanism allows Ethereum nodes to temporarily store and access off-chain data, reducing storage requirements. It is expected to significantly lower transaction costs for Ethereum dApps, especially benefiting Layer 2 networks.
