}

expected coin keeper

type CodeType 

type CodeType = sdk.CodeType
const (
	DefaultCodespace            sdk.CodespaceType = "DISTR"

type DelegatorStartingInfo

starting info for a delegator reward period tracks the previous validator period, the delegation's amount of staking token, and the creation height (to check later on if any slashes have occurred) NOTE that even though validators are slashed to whole staking tokens, the delegators within the validator may be left with less than a full token, thus sdk.Dec is used
