The Dencun upgrade was forked on the Goerli testnet around 1:35 a.m. ET, core developers confirmed in a livestream. 

The central feature of this Dencun deployment (on Goerli) is the introduction of EIP-4844 — a novel transaction mechanism known as ephemeral blobs or proto-danksharding. This approach allows for the temporary storage and access of off-chain data by Ethereum nodes to reduce storage demands. It is expected to substantially lower transaction costs for Ethereum dApps, particularly benefiting Layer 2 rollup chains.

In preparation for this transition, the development team has …
