# `params`
|
|
|
|
## Abstract
|
|
|
|
Package params provides a globally available parameter store.
|
|
|
|
There are two main types, Keeper and Subspace. Subspace is an isolated namespace for a
|
|
paramstore, where keys are prefixed by preconfigured spacename. Keeper has a
|
|
permission to access all existing spaces.
|
|
|
|
Subspace can be used by the individual keepers, which need a private parameter store
|
|
that the other keepers cannot modify. The params Keeper can be used to add a route to `x/gov` router in order to modify any parameter in case a proposal passes.
|
|
|
|
The following contents explains how to use params module for master and user modules.
