Ledger state associated with a block

Consensus often needs some more functionality than the ledger currently provides.
Either the functionality shouldn't or can't live in the ledger, in which case
it can be part and remain part of ShelleyBasedEra. Or, the functionality
should live in the ledger, but hasn't yet been added to the ledger, or it
hasn't yet been propagated to this repository, in which case it can be added
to this class until that is the case.
If this class becomes redundant, We can move it to ledger and re-export it from here.
TODO Currently we include some constraints on the update state which are needed to determine the hard fork point. In the future this should be replaced with an appropriate API - see https://github.com/input-output-hk/ouroboros-network/issues/2890

data family Ticked st Source #
" Ticked " piece of state (LedgerState, LedgerView, ChainIndepState)
Ticking refers to the passage of time (the ticking of the clock). When a piece of state is marked as ticked, it means that time-related changes have been applied to the state (or forecast).
Some examples of time related changes:
- Scheduled delegations might have been applied in Byron
- New leader schedule computed for Shelley
- Transition from Byron to Shelley activated in the hard fork combinator.
- Nonces switched out at the start of a new epoch.
