Parameter Change Proposal
A parameter change proposal is a governance action that proposes to change a specific module parameter of the network.
Create a proposal JSON file:
{
"messages": [
{
"@type": "/cosmos.gov.v1.MsgExecLegacyContent",
"authority": "zeta10d07y265gmmuvt4z0w9aw880jnsr700jvxasvr",
"content": {
"@type": "/cosmos.params.v1beta1.ParameterChangeProposal",
"changes": [
{
"subspace": "gov",
"key": "votingparams",
"value": "{ \"voting_period\": \"86400000000000\" }"
}
],
"description": "Update voting period to 24 hours",
"title": "Gov Param Change"
}
}
],
"deposit": "1000000azeta",
"metadata": "https://example.org/metadata.json"
}
The proposal above uses the MsgExecLegacyContent message type to wrap the
ParameterChangeProposal message.
The changes array contains a list of changes to be made to the network's
parameters. Each change is a JSON object with the following fields:
subspace: The module whose parameter is being changed.key: The parameter key.value: The new value of the parameter.
Subspaces and Keys
| Subspace | Key |
|---|
To query the current value of a parameter, use the the following endpoint. Fill
out the subspace and key query parameters with the values from the table
above.
For example,
Returns:
{
"param": {
"key": "MaxValidators",
"subspace": "staking",
"value": "100"
}
}
You now know that the value of the MaxValidators key in the staking subspace
is an integer (currently, 100). You can use the parameter change proposal to
change this value to something else.
