The next major network upgrade for Ethereum, called the “Dencun Upgrade”, was successfully launched on the Ethereum testnet Sepolia last night, signaling that only one more testnet stands between the implementation of the “proto-danksharding” feature on the Ethereum mainnet.
Proto-danksharding aims to reduce the transaction costs and data availability costs of the 2-layer network by introducing a new data structure called “blob”. As the number of 2-layer networks on Ethereum is rapidly increasing, this upgrade is seen as an important part of the ecosystem roadmap. Following the upgrade, the new data structure named “Blob” is now flowing within the Sepolia network.
Ethereum co-founder Vitalik Buterin explained that earlier this month, Ethereum core developers deployed the first testnet upgrade on the Goerli testnet. After the completion of the Sepolia upgrade, Ethereum core developers will conduct the final test on the Holesky testnet on February 7th, following which developers will sign the date to activate the Dencun upgrade on the main blockchain.
