Democracy¶

Calls¶

blacklist¶

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).

remove_other_vote¶

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.

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.

FastTrackVotingPeriod¶

Minimum voting period allowed for a fast-track referendum.

Value¶

Python¶

constant = substrate.get_constant('Democracy', 'FastTrackVotingPeriod')

InstantAllowed¶

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.

Value¶

True

Python¶

Value¶

Python¶

constant = substrate.get_constant('Democracy', 'MaxVotes')

MinimumDeposit¶

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

Value¶

100000000000000

Python¶

constant = substrate.get_constant('Democracy', 'MinimumDeposit')

VoteLockingPeriod¶

The minimum period of vote locking.

It should be no shorter than enactment period to ensure that in the case of an approval, those successful voters are locked into the consequences that their votes entail.

Value¶

Python¶

constant = substrate.get_constant('Democracy', 'VoteLockingPeriod')
