activateDelegations ∷ SlotNumber → State → State Source #

Activate certificates up to this slot

delegates ∷ State → VerificationKey → VerificationKey → Bool Source #

Check whether a delegation is valid in the State

delegationMap ∷ State → Map Source #

initialState ∷ MonadError Error m ⇒ Environment → GenesisDelegation → m State Source #

The initial state maps each genesis key to itself and overrides this using certificates from the genesis block.

tickDelegation ∷ EpochNumber → SlotNumber → State → State Source #

Perform delegation update without adding certificates

updateDelegation ∷ MonadError Error m ⇒ Environment → State → [ACertificate ByteString] → m State Source #

Update the State with a list of new Certificates

This corresponds to the DELEG rule from the Byron ledger specification
