NewEpochState

The nested structure of NewEpochState

The NewEpochState contains the bulk of the ledger state, and is in fact was the consensus layer refers to as the ledger state. The NewEpochState is also the same data that is produce by the cardano-cli command cardano-cli query ledger-state. This page can be used to navigate the nested structure of this type.

Note about DState

In the implementation (but not the spec), the first three maps in DState are combined into a single map of type UnifiedMap.
