Ethereum ‘s latest major upgrade, Dencun, went live on the Sepolia Testnet on Tuesday, leaving just one more Testnet before it can deliver the benefits of its anticipated “proto-danksharding” feature.

Dencun’s test on Sepolia began at 22:51 UTC on Tuesday and was quickly completed. Ethereum Foundation DevOps engineer Parithosh Jayanthi said in a tweet, “Blobs are now flowing on Sepolia” and “Eventless Testnet forks are the best!”
Ethereum core developers deployed the upgrade on the Goerli testnet in early January. The upgrade is scheduled to be launched on the third and final testnet, Holesky, on February 7th.
After the third successful Testnet deployment, the Ethereum team is expected to set a Mainnet launch date for Dencun.
One of the features Dencun is expected to bring is proto-danksharding, which aims to improve scalability by reducing gas fees and introducing a new, compressed data storage mechanism called “blobs.”
In a statement, Ethereum co-founder Vitalik Buterin said, “A blob-carrying transaction is like a normal transaction, but it also carries an extra piece of data called a blob. Blobs can be extremely large and can be much cheaper than similar amounts of calldata.“
Ethereum’s last major upgrade, Shapella, was released in March 2023. This upgrade allowed users and validators to withdraw their staked ETH from the network.
