    'Democracy', 'DepositOf', ['u32']
)

Return value¶

(['AccountId'], 'u128')

LowestUnbaked¶

The lowest referendum index representing an unbaked referendum. Equal to ReferendumCount if there isn't a unbaked referendum.

Constants¶

EnactmentPeriod¶

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.

Value¶

Python¶

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

FastTrackVotingPeriod¶

Minimum voting period allowed for a fast-track referendum.

Value¶

Python¶

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

MaxDeposits¶

The maximum number of deposits a public proposal may have at any time.

Value¶

Python¶

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

MaxProposals¶

The maximum number of public proposals that can exist at any time.

Value¶

Python¶

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

MaxVotes¶

The maximum number of votes for an account.

Also used to compute weight, an overly big value can lead to extrinsic with very big weight.

Value¶

Python¶

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

MinimumDeposit¶

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

Value¶

2500000000000

Python¶

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

VotingPeriod¶

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

Value¶

Python¶

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

Errors¶

Imminent¶

Imminent

InsufficientFunds¶

Too high a balance was provided that the account cannot afford.

NoneWaiting¶

No proposals waiting

NotImminent¶

Not imminent

NotProposer¶

NotVoter¶
