The Ethereum Foundation’s Tim Beiko has announced that core Ethereum developers have set a precise time for implementing the Dencun upgrade.
This upgrade, featuring the eagerly awaited proto-dank sharding functionality via EIP-4844, is slated for activation at slot number 8626176.
Based on current estimates, this slot is expected to occur around 8:55 am ET on March 13. The Dencun upgrade will introduce various technical improvements, including blob transactions and temporary storage.
EIP-4844 seeks to integrate off-chain “data blobs” into Ethereum transactions, allowing for additional data inclusion without impacting block processing speeds.
Proto-dank sharding is a sharding approach that introduces “blob-carrying transactions” to increase block space on Ethereum layer-2 networks like zkSync, Optimism, and Arbitrum, assisting in meeting their data storage needs.
In the Proto-dank sharding plan, each block will be limited to containing 16 blobs, each no longer than 128 kb, as outlined by Blocknative. This is anticipated to add approximately 2 MB of block space.
