## Delegating to a Validator
|
||||
|
||||
On the upcoming mainnet, you can delegate `atom` to a validator. These [delegators](https://cosmos.network/resources/delegators) can receive part of the validator's fee revenue. Read more about the [Cosmos Token Model](https://github.com/cosmos/cosmos/raw/master/Cosmos_Token_Model.pdf).

## Governance
|
||||
|
||||
Governance is the process from which users in the Cosmos Hub can come to consensus on software upgrades, parameters of the mainnet or on custom text proposals. This is done through voting on proposals, which will be submitted by `Atom` holders on the mainnet.
|
||||
|
||||
Some considerations about the voting process:
|
||||
|
||||
- Voting is done by bonded `Atom` holders on a 1 bonded `Atom` 1 vote basis
|
||||
- Delegators inherit the vote of their validator if they don't vote
|
||||
- **Validators MUST vote on every proposal**. If a validator does not vote on a proposal, they will be **partially slashed**
|
||||
- Votes are tallied at the end of the voting period (2 weeks on mainnet). Each address can vote multiple times to update its `Option` value (paying the transaction fee each time), only the last casted vote will count as valid
|
||||
- Voters can choose between options `Yes`, `No`, `NoWithVeto` and `Abstain`
|
||||
At the end of the voting period, a proposal is accepted if `(YesVotes/(YesVotes+NoVotes+NoWithVetoVotes))>1/2` and `(NoWithVetoVotes/(YesVotes+NoVotes+NoWithVetoVotes))<1/3`. It is rejected otherwise
|
||||
|
||||
For more information about the governance process and how it works, please check out the Governance module [specification](https://github.com/cosmos/cosmos-sdk/tree/develop/docs/spec/governance).
|
||||
|
||||
### Create a Governance proposal
|
||||
|
||||
In order to create a governance proposal, you must submit an initial deposit along with the proposal details:
|
||||
|
||||
- `title`: Title of the proposal
|
||||
- `description`: Description of the proposal
|
||||
- `type`: Type of proposal. Must be of value _Text_ (types _SoftwareUpgrade_ and _ParameterChange_ not supported yet).
|
||||
|
||||
```bash
|
||||
gaiacli gov submit-proposal \
|
||||
--title=<title> \
|
||||
--description=<description> \
|
||||
--type=<Text/ParameterChange/SoftwareUpgrade> \
|
||||
--proposer=<account_cosmosaccaddr> \
|
||||
--deposit=<40steak> \
|
||||
--from=<name> \
|
||||
--chain-id=gaia-7000
|
||||
```
|
||||
|
||||
|
||||
### Increase deposit
|
||||
|
||||
In order for a proposal to be broadcasted to the network, the amount deposited must be above a `minDeposit` value (default: `10 steak`). If the proposal you previously created didn't meet this requirement, you can still increase the total amount deposited to activate it. Once the minimum deposit is reached, the proposal enters voting period:
|
||||
|
||||
```bash
|
||||
gaiacli gov deposit \
|
||||
--proposalID=<proposal_id> \
|
||||
--depositer=<account_cosmosaccaddr> \
|
||||
--deposit=<200steak> \
|
||||
--from=<name> \
|
||||
--chain-id=gaia-7000
|
||||
```
|
||||
|
||||
> _NOTE_: Proposals that don't meet this requirement will be deleted after `MaxDepositPeriod` is reached.
|
||||
|
||||
#### Query proposal
|
||||
|
||||
Once created, you can now query information of the proposal:
|
||||
|
||||
```bash
|
||||
gaiacli gov query-proposal \
|
||||
--proposalID=<proposal_id> \
|
||||
--chain-id=gaia-7000
|
||||
```
|
||||
|
||||
### Vote on a proposal
|
||||
|
||||
After a proposal's deposit reaches the `MinDeposit` value, the voting period opens. Bonded `Atom` holders can then cast vote on it:
|
||||
|
||||
```bash
|
||||
gaiacli gov vote \
|
||||
--proposalID=<proposal_id> \
|
||||
--voter=<account_cosmosaccaddr> \
|
||||
--option=<Yes/No/NoWithVeto/Abstain> \
|
||||
--from=<name> \
|
||||
--chain-id=gaia-7000
|
||||
```
|
||||
|
||||
#### Query vote
|
||||
|
||||
Check the vote with the option you just submitted:
|
||||
|
||||
```bash
|
||||
gaiacli gov query-vote \
|
||||
--proposalID=<proposal_id> \
|
||||
--voter=<account_cosmosaccaddr> \
|
||||
--chain-id=gaia-7000

||||
```
