EIP-4844 introduces blob-carrying transactions that move rollup data off permanent Ethereum storage and into temporary “blobs,” cutting the cost layer-2 networks pay to post data to layer 1. Known as proto-danksharding, it creates a separate blob gas market alongside regular gas, so blob pricing floats independently of normal transaction fees. The catch: the EVM never reads blob contents directly. It only sees a versioned hash pointing to data stored elsewhere.
