Type Alias manual_slash

This function allows governance to manually slash a validator and is a fallback mechanism.

The dispatch origin must be T::AdminOrigin.

Parameters

• validator_stash - The stash account of the validator to slash.
• era - The era in which the validator was in the active set.
• slash_fraction - The percentage of the stake to slash, expressed as a Perbill.

Behavior

The slash will be applied using the standard slashing mechanics, respecting the configured SlashDeferDuration.

This means:

• If the validator was already slashed by a higher percentage for the same era, this slash will have no additional effect.
• If the validator was previously slashed by a lower percentage, only the difference will be applied.
• The slash will be deferred by SlashDeferDuration eras before being enacted.
