NewEpochState - IntersectMBO/cardano-ledger GitHub Wiki
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.

single map
of type UnifiedMap.
