Instances

Constructors
| NonGenesisUpdatePPUP !(Set (KeyHash 'Genesis (EraCrypto era))) !(Set (KeyHash 'Genesis (EraCrypto era))) | An update was proposed by a key hash that is not one of the genesis keys. The first set contains the key hashes which were a part of the update. The second set contains the key hashes of the genesis keys. |
| PPUpdateWrongEpoch !EpochNo !EpochNo !VotingPeriod | An update was proposed for the wrong epoch.
The first |
| PVCannotFollowPPUP !ProtVer | An update was proposed which contains an invalid protocol version. New protocol versions must either increase the major number by exactly one and set the minor version to zero, or keep the major version the same and increase the minor version by exactly one. |

type family PredicateFailure a Source #
Descriptive type for the possible failures which might cause a transition to fail.
As a convention, PredicateFailures which are "structural" (meaning that
they are not "throwable" in practice, and are used to pass control from
one transition rule to another) are prefixed with S_.
Structural PredicateFailures represent conditions between rules where
the disjunction of all rules' preconditions is equal to True. That is,
either one rule will throw a structural PredicateFailure and the other
will succeed, or vice-versa.

Deprecated: In favor of EraRuleFailure PPUP era
Arguments
| ∷ ∀ era. EraPParams era | |
| ⇒ ProposedPPUpdates era | |
| → PParams era | Protocol parameters to which the change will be applied. |
| → Word64 | Quorum needed to change the protocol parameters. |
| → Maybe (PParams era) |
If at least n nodes voted to change the same protocol parameters to
the same values, return the given protocol parameters updated to these
values. Here n is the quorum needed.
