关于 Starcoin 治理的更多信息请参看：

• Starcoin 技术白皮书中的治理部分
• 链上治理的生命周期
• 通过治理机制修改 DAO 的设置

注意：投票时，会将当前账户的 STC 抵押到合约中，直到投票结束，当前投票周期为 7 天。期间主动退款则视为放弃投票。** 为了鼓励参与链上治理，未来会推出链上治理的激励措施。本次参与投票的用户会根据激励策略进行补偿。**

投票操作指南

准备

1. 下载 starcoin 版本 v1.8.0-rc.1，并同步主网的区块，进入 starcoin 控制台。
2. 将自己的账户导入到节点内置的钱包中，或者从交易所提币到节点钱包的地址中。

操作命令

1. 查看投票状态

dev call --function 0x1::Dao::proposal_state -t 0x1::STC::STC -t 0x1::UpgradeModuleDaoProposal::UpgradeModuleV2 --arg 0xbfc6a0138b5a596c8080303c32160119 --arg 8

第一个参数是提案发起人的地址，第二个参数是提案 id，返回的状态为 1 表示等待状态， 2 表示正在投票中，4 表示投票通过。

2. 执行投票

通过一下命令进行投票：

account execute-function -s your_address --function 0x1::DaoVoteScripts::cast_vote -t 0x1::STC::STC -t 0x1::UpgradeModuleDaoProposal::UpgradeModuleV2 --arg 0xbfc6a0138b5a596c8080303c32160119 --arg 8 --arg true --arg 1000000000u128 -b

第一个参数是提案发起人的地址，第二个参数是提案 id，第三个参数通过 true/false 表示同意和反对，第四个参数表示用来投票的 STC 数量，注意单位是 nanoSTC，有9位是小数点后的单位，上面的例子是 1 STC。

注意：替换 your_address 为你自己的地址，不要用全部的 STC，要留够 gas 费。

3. 放弃投票

如果想放弃投票，取回抵押的 STC，可以用以下命令：

account execute-function -s your_address --function 0x1::DaoVoteScripts::revoke_vote -t 0x1::STC::STC -t 0x1::UpgradeModuleDaoProposal::UpgradeModuleV2 --arg 0xbfc6a0138b5a596c8080303c32160119 --arg 8 -b

4. 投票结束后取回抵押的 STC

account execute-function -s your_address --function 0x1::DaoVoteScripts::unstake_vote -t 0x1::STC::STC -t 0x1::UpgradeModuleDaoProposal::UpgradeModuleV2 --arg 0xbfc6a0138b5a596c8080303c32160119 --arg 8 -b

5. 查看投票结果

dev call --function 0x1::Dao::proposal_info -t 0x1::STC::STC -t 0x1::UpgradeModuleDaoProposal::UpgradeModuleV2 --arg 0xbfc6a0138b5a596c8080303c32160119

{
  "ok": [
    8,
    1635751110821,
    1636355910821,
    0,
    0
  ]
}

返回值的第一个数表示提案 id，第二个数是开始时间，第三个数是结束时间，第四个数是投票同意的票数，第五个数是投票反对的票数。

Voting Operation Guide

Preparation

1. Download the starcoin v1.8.0-rc.1 and join the mainnet.
2. Import your account into the node's built-in wallet or withdraw coins from the exchange to the node's wallet address.

Operation commands

1. Check the voting status

dev call --function 0x1::Dao::proposal_state -t 0x1::STC::STC -t 0x1::UpgradeModuleDaoProposal::UpgradeModuleV2 --arg 0xbfc6a0138b5a596c8080303c32160119 --arg 8

The first argument is the address of the proposer, the second argument is the proposal id, and the returned status is 1 for pending status, 2 for voting, and 4 for voting passed.

2. Execute voting

Voting is performed by the following command.

account execute-function -s your_address --function 0x1::DaoVoteScripts::cast_vote -t 0x1::STC::STC -t 0x1:: UpgradeModuleDaoProposal::UpgradeModuleV2 --arg 0xbfc6a0138b5a596c8080303c32160119 --arg 8 --arg true --arg 1000000000u128 -b

The first argument is the proposer, the second argument is the proposal id, the third argument indicates agreement and disagreement via true/false, and the fourth argument indicates the number of STCs used to vote, note that the unit is nanoSTC with 9 decimal places, the above example is 1 STC.

Note: Replace your_address with your own address, do not use all the STCs, but leave enough for the gas fee.

3. Revoke Voting

If you want to abort the poll and get back the STCs, you can use the following command.

account execute-function -s your_address --function 0x1::DaoVoteScripts::revoke_vote -t 0x1::STC::STC -t 0x1:: UpgradeModuleDaoProposal::UpgradeModuleV2 --arg 0xbfc6a0138b5a596c8080303c32160119 --arg 8 -b

4. retrieve the staked STC after the poll

account execute-function -s your_address --function 0x1::DaoVoteScripts::unstake_vote -t 0x1::STC::STC -t 0x1:: UpgradeModuleDaoProposal::UpgradeModuleV2 --arg 0xbfc6a0138b5a596c8080303c32160119 --arg 8 -b

5. View poll results

dev call --function 0x1::Dao::proposal_info -t 0x1::STC::STC -t 0x1::UpgradeModuleDaoProposal::UpgradeModuleV2 --arg 0xbfc6a0138b5a596c8080303c32160119

{
  "ok": [
    8,
    1635751110821,
    1636355910821,
    0,
    0
  ]
}

The first number of the return value represents the proposal id, the second number is the start time, the third number is the end time, the fourth number is the number of votes for and the fifth number is the number of votes against.
