Proto-Danksharding
An Ethereum upgrade (EIP-4844) that introduced blob-carrying transactions as a stepping stone toward full danksharding. Proto-danksharding creates a new transaction type that carries large data blobs with a separate fee market, dramatically reducing the cost for Layer 2 rollups to post data to Ethereum. It went live in Ethereum's Dencun upgrade in March 2024 and reduced L2 fees by 90-99%.
