    proposal_hash: T::Hash
) -> DispatchResult

Schedule a negative-turnout-bias referendum to be tabled next once it is legal to schedule an external referendum.

The balance delegated is locked for as long as it’s delegated, and thereafter for the time appropriate for the conviction’s lock period.

The dispatch origin of this call must be Signed, and the signing account must either:

• be delegating already; or

• have no voting activity (if there is, then it will need to be removed/consolidated through reap_vote or unvote).

Weight: O(1).

pub fn note_preimage(
    origin: OriginFor<T>,
    encoded_proposal: Vec<u8>
) -> DispatchResult

The dispatch origin of this call must be Signed.

• encoded_proposal: The preimage of a proposal.

Emits PreimageNoted.

Weight: O(E) with E size of encoded_proposal (protected by a required deposit).

pub fn note_preimage_operational(
    origin: OriginFor<T>,
    encoded_proposal: Vec<u8>
) -> DispatchResult

Same as note_preimage but origin is OperationalPreimageOrigin.

pub fn note_imminent_preimage(
    origin: OriginFor<T>,
    encoded_proposal: Vec<u8>
) -> DispatchResultWithPostInfo

Register the preimage for an upcoming proposal. This requires the proposal to be in the dispatch queue. No deposit is needed. When this call is successful, i.e. the preimage has not been uploaded before and matches some imminent proposal, no fee is paid.

The dispatch origin of this call must be Signed.

• encoded_proposal: The preimage of a proposal.

Emits PreimageNoted.

Weight: O(E) with E size of encoded_proposal (protected by a required deposit).

pub fn note_imminent_preimage_operational(
    origin: OriginFor<T>,
    encoded_proposal: Vec<u8>
) -> DispatchResultWithPostInfo

Same as note_imminent_preimage but origin is OperationalPreimageOrigin.

pub fn reap_preimage(
    origin: OriginFor<T>,
    proposal_hash: T::Hash,
    proposal_len_upper_bound: u32
) -> DispatchResult

Remove an expired proposal preimage and collect the deposit.

The dispatch origin of this call must be Signed.

• proposal_hash: The preimage hash of a proposal.
• proposal_length_upper_bound: an upper bound on length of the proposal. Extrinsic is weighted according to this value with no refund.

This will only work after VotingPeriod blocks from the time that the preimage was noted, if it’s the same account doing it. If it’s a different account, then it’ll only work an additional EnactmentPeriod later.

Emits PreimageReaped.

Weight: O(D) where D is length of proposal.

pub fn unlock(
    origin: OriginFor<T>,
    target: <<T as Config>::Lookup as StaticLookup>::Source
) -> DispatchResult

Unlock tokens that have an expired lock.

The dispatch origin of this call must be Signed.

• target: The account to remove the lock on.

Weight: O(R) with R number of vote of target.

pub fn remove_vote(
    origin: OriginFor<T>,
    index: ReferendumIndex
) -> DispatchResult

Remove a vote for a referendum.

If:

• the referendum was cancelled, or
• the referendum is ongoing, or
• the referendum has ended such that
  • the vote of the account was in opposition to the result; or
  • there was no conviction to the account’s vote; or
  • the account made a split vote …then the vote is removed cleanly and a following call to unlock may result in more funds being available.

If, however, the referendum has ended and:

• it finished corresponding to the vote of the account, and
• the account made a standard vote with conviction, and
• the lock period of the conviction is not over …then the lock will be aggregated into the overall account’s lock, which may involve overlocking (where the two locks are combined into a single lock that is the maximum of both the amount locked and the time is it locked for).

The dispatch origin of this call must be Signed, and the signer must have a vote registered for referendum index.

• index: The index of referendum of the vote to be removed.

Weight: O(R + log R) where R is the number of referenda that target has voted on. Weight is calculated for the maximum number of vote.

pub fn remove_other_vote(
    origin: OriginFor<T>,
    target: <<T as Config>::Lookup as StaticLookup>::Source,
    index: ReferendumIndex
) -> DispatchResult

Remove a vote for a referendum.

If the target is equal to the signer, then this function is exactly equivalent to remove_vote. If not equal to the signer, then the vote must have expired, either because the referendum was cancelled, because the voter lost the referendum or because the conviction period is over.

The dispatch origin of this call must be Signed.

• target: The account of the vote to be removed; this account must have voted for referendum index.
• index: The index of referendum of the vote to be removed.

Weight: O(R + log R) where R is the number of referenda that target has voted on. Weight is calculated for the maximum number of vote.

pub fn enact_proposal(
    origin: OriginFor<T>,
    proposal_hash: T::Hash,
    index: ReferendumIndex
) -> DispatchResult

Enact a proposal from a referendum. For now we just make the weight be the maximum.

pub fn blacklist(
    origin: OriginFor<T>,
    proposal_hash: T::Hash,
    maybe_ref_index: Option<ReferendumIndex>
) -> DispatchResult

Permanently place a proposal into the blacklist. This prevents it from ever being proposed again.

If called on a queued public or external proposal, then this will result in it being removed. If the ref_index supplied is an active referendum with the proposal hash, then it will be cancelled.

The dispatch origin of this call must be BlacklistOrigin.

• proposal_hash: The proposal hash to blacklist permanently.
• ref_index: An ongoing referendum whose hash is proposal_hash, which will be cancelled.

Weight: O(p) (though as this is an high-privilege dispatch, we assume it has a reasonable value).

pub fn cancel_proposal(
    origin: OriginFor<T>,
    prop_index: PropIndex
) -> DispatchResult

Remove a proposal.

The dispatch origin of this call must be CancelProposalOrigin.

• prop_index: The index of the proposal to cancel.

Weight: O(p) where p = PublicProps::<T>::decode_len()
