Ouroboros.Consensus.HardFork.Combinator.Protocol.LedgerView

Synopsis

Hard fork

data HardForkLedgerView_ f xs Source #

Constructors

HardForkLedgerView 

Fields

Type family instances

data family Ticked st ∷ Type Source #

" Ticked " piece of state, either LedgerState or ChainDepState

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. There are exactly two methods in the interface that do that: tickChainDepState and applyChainTickLedgerResult.

Also note that a successful forecast forecastFor (ledgerViewForecastAt cfg st) slot must equal protocolLedgerView cfg (applyChainTick cfg slot st). Thus a LedgerView can only be projected from a Ticked state, but cannot itself be ticked.

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.
