## Keepers
## Keeper

The Keeper of the `x/consensus` module provides the following functions:

* `Params`: Retrieves the current consensus parameters.

* `UpdateParams`: Updates the consensus parameters. Only the authority can perform this operation.

* `BlockParams`: Returns the maximum gas and bytes allowed in a block.

* `ValidatorPubKeyTypes`: Provides the list of public key types allowed for validators.

* `EvidenceParams`: Returns the evidence parameters, including maximum age and bytes.

* `AppVersion`: Returns the current application version.


Note: It is recommended to use the `x/consensus` module keeper to get consensus params instead of accessing them through the context.

The consensus module provides methods to Set and Get consensus params. It is recommended to use the `x/consensus` module keeper to get consensus params instead of accessing them through the context.
