Associated Types

`type Proposal: Parameter + Dispatchable<Origin = Self::Origin> + From<Call<Self>>`

`type Event: From<Event<Self>> + Into<Self::Event>`

`type Currency: ReservableCurrency<Self::AccountId> + LockableCurrency<Self::AccountId, Moment = Self::BlockNumber>`

Currency type for this module.

`type EnactmentPeriod: Get<Self::BlockNumber>`

The minimum period of locking and the period between a proposal being approved and enacted.

It should generally be a little more than the unstake period to ensure that voting stakers have an opportunity to remove themselves from the system in the case where they are on the losing side of a vote.

`type LaunchPeriod: Get<Self::BlockNumber>`

How often (in blocks) new public referenda are launched.

`type VotingPeriod: Get<Self::BlockNumber>`

How often (in blocks) to check for new votes.

`type MinimumDeposit: Get<<Self::Currency as Currency<Self::AccountId>>::Balance>`

The minimum amount to be used as a deposit for a public referendum proposal.

`type ExternalOrigin: EnsureOrigin<Self::Origin>`

Origin from which the next tabled referendum may be forced. This is a normal "super-majority-required" referendum.

`type ExternalMajorityOrigin: EnsureOrigin<Self::Origin>`

Origin from which the next tabled referendum may be forced; this allows for the tabling of a majority-carries referendum.

`type ExternalDefaultOrigin: EnsureOrigin<Self::Origin>`

Origin from which the next tabled referendum may be forced; this allows for the tabling of a negative-turnout-bias (default-carries) referendum.

`type FastTrackOrigin: EnsureOrigin<Self::Origin>`

Origin from which the next majority-carries (or more permissive) referendum may be tabled to vote according to the FastTrackVotingPeriod asynchronously in a similar manner to the emergency origin. It retains its threshold method.

`type InstantOrigin: EnsureOrigin<Self::Origin>`

Origin from which the next majority-carries (or more permissive) referendum may be tabled to vote immediately and asynchronously in a similar manner to the emergency origin. It retains its threshold method.

`type InstantAllowed: Get<bool>`

Indicator for whether an emergency origin is even allowed to happen. Some chains may want to set this permanently to false, others may want to condition it on things such as an upgrade having happened recently.
