Blob Storage

Blob storage refers to a specific type of data storage on the Ethereum main chain designed to hold large amounts of rollup data at a lower cost than standard transaction calldata. These blobs are temporary, meaning they are pruned after a set period, which reduces the long-term storage burden on nodes.

This innovation is specifically optimized for rollups, as they only need the data to be available long enough for validity proofs to be generated and verified. By separating this data from the main execution state, the network can significantly increase its capacity to handle rollup batches.
