Cast Vote

Cast a vote on a poll. POST only. Javadoc

Request: Refer to Create Transaction Request for common parameters.

  • requestType is castVote
  • chain the chain related to the operation (eg: IGNIS)
  • poll is the poll ID
  • vote00 is an integer within the allowed range to vote for option (answer) 0 (optional if minNumberOfOptions met, default is -128)
  • vote01 is an integer within the allowed range to vote for option (answer) 1 (optional if minNumberOfOptions met, default is -128)
  • vote02 is an integer within the allowed range to vote for option (answer) 2 (optional if minNumberOfOptions met, default is -128)

Note: The allowed vote values are integers between minRangeValue and maxRangeValue, inclusive. This range, along with the minimum and maximum number of options that can and must be voted on are specified when the poll is created. Refer to Create Poll.

Response: Refer to Create Transaction Response.

Create Poll

Create a new poll. POST only. Javadoc

Request: Refer to Create Transaction Request for common parameters.

  • requestType is createPoll
  • chain the chain related to the operation (eg: IGNIS)
  • name is the name of the poll
  • description is the description of the poll, or the question to be answered
  • finishHeight is the block height when the poll is completed
  • votingModel is 0 for One Vote Per Account, 1 for Vote By tokens Balance, 2 for Vote By Asset Balance and 3 for Vote By Currency Balance
  • minNumberOfOptions is the minimum number of options (answers) that must be voted for
  • maxNumberOfOptions is the maximum number of options (answers) that can be voted for
  • minRangeValue is the minimum integer value for an option (answer) (>= 0)
  • maxRangeValue is the maximum integer value for an option (answer) (>= minRangeValue)
  • minBalance is the minimum balance (in NQT or QNT) required for voting (optional, default 0)
  • minBalanceModel is (required if minBalance > 0, must match votingModel when votingModel > 0)
    • 1 for chain balance
    • 2 for an asset balance
    • 3 for a currency balance
  • holding is the asset or currency ID (required if minBalanceModel > 1)
  • option00 is the name of option (answer) 0
  • option01 is the name of option (answer) 1 (optional)
  • option02 is the name of option (answer) 2 (optional)

Notes: Up to 100 options (answers) can be specified, but there is an extra fee for each option beyond 20. Unlike the API, the NRS client treats a vote of 0 as a nonvote not contributing to the number answers (options) chosen. The NRS client uses checkboxes for selecting answers when minRangeValue = 0 and maxRangeValue = 1; otherwise sliding controls are used to select answers from the allowed range.

Note: When a balance affects the poll result, the result depends only on the balance (including pending outgoing phased transfers) computed just prior to the finish height.

Response: Refer to Create Transaction Response. The transaction ID is also the poll ID.
