The Ethereum Foundation Blog announced on Tuesday that the Dencun network upgrade has been successfully activated on all testnets.
“Two years after its ETHDenver inception, dozens of testing calls and devnets later, protodanksharding is finally going live on mainnet,” stated the Ethereum Foundation.
According to the blog post, Dencun will be activated on the Ethereum mainnet on March 13 at epoch 269568. The activation is scheduled for 13:55 UTC, or 8:55 am ET.
As reported by Christine Kim from Galaxy on X, March 13 was the anticipated activation date, although the exact timestamp was previously unknown. Stakers are required to update their beacon nodes and validator clients to ensure compatibility with the upgrade.
quick notes from the eth dev call this morning, acdc #128:

As of February 23, “all client teams, except Lodestar, have released final software versions for the Dencun upgrade,” mentioned Kim.
Earlier this month, the upgrade was successfully implemented on the Holešky testnet. It had previously undergone testing on the Goerli and Sepolia testnets.
The Dencun upgrade will introduce proto-danksharding to the Ethereum blockchain. Under EIP-4844, rollups can append “blobs” of data on a beacon node.
According to a post on the Ethereum Org’s website in early January, “The data in these blobs is not accessible to the EVM and is automatically deleted after a fixed time period (1-3 months). This means rollups can send their data much more cheaply and pass the savings on to end users in the form of cheaper transactions.”
Additionally, the Ethereum Foundation post mentioned that the name Dencun is a fusion of star and Devcon city names. Specifically, Dencun combines Deneb — a star — and the location of Devcon 3, Cancun.
