-## 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.
