Functions

func BeginBlocker

func BeginBlocker(ctx sdk.Context, k Keeper)

Called every block, process inflation on the first block of every hour

func InitGenesis

func InitGenesis(ctx sdk.Context, keeper Keeper, data GenesisState)

new mint genesis

func ParamTypeTable

func ParamTypeTable() params.TypeTable

ParamTable for stake module

func ValidateGenesis

func ValidateGenesis(data GenesisState) error

ValidateGenesis validates the provided staking genesis state to ensure the expected invariants holds. (i.e. params in correct bounds, no duplicate validators)

Types

type FeeCollectionKeeper

type FeeCollectionKeeper interface {
	AddCollectedFees(sdk.Context, sdk.Coins) sdk.Coins
}

expected fee collection keeper interface

type GenesisState

type GenesisState struct {
	Minter Minter `json:"minter"` // minter object
	Params Params `json:"params"` // inflation params
}

GenesisState - all distribution state that must be provided at genesis

func DefaultGenesisState

func DefaultGenesisState() GenesisState

get raw genesis raw message for testing

func NewGenesisState

func NewGenesisState(minter Minter, params Params) GenesisState

func WriteGenesis

func WriteGenesis(ctx sdk.Context, keeper Keeper) GenesisState

WriteGenesis returns a GenesisState for a given context and keeper. The GenesisState will contain the pool, and validator/delegator distribution info's

func (Keeper) SetParams

func (k Keeper) SetParams(ctx sdk.Context, params Params)

set inflation params from the global param store

type Minter

type Minter struct {
	InflationLastTime time.Time `json:"inflation_last_time"` // block time which the last inflation was processed
	Inflation         sdk.Dec   `json:"inflation"`           // current annual inflation rate
}
