Module da

The da module defines traits used by the full node to interact with the DA layer.

Traits

DaService

A DaService is the local side of an RPC connection talking to a node of the DA layer It is not part of the logic that is zk-proven.

SlotData

SlotData is the subset of a DA layer block which is stored in the rollup’s database. At the very least, the rollup needs access to the hashes and headers of all DA layer blocks, but rollups may choose to store partial (or full) block data as well.
