Keeper of the inflation store

func NewKeeper 

func NewKeeper(
	cdc codec.BinaryCodec,
	storeKey storetypes.StoreKey,
	paramspace paramstypes.Subspace,
	accountKeeper types.AccountKeeper,
	bankKeeper types.BankKeeper,
	distributionKeeper types.DistrKeeper,
	stakingKeeper types.StakingKeeper,
	sudoKeeper types.SudoKeeper,
	feeCollectorName string,
) Keeper

NewKeeper creates a new mint Keeper instance

func (Keeper) AfterEpochEnd 

func (k Keeper) AfterEpochEnd(ctx sdk.Context, epochIdentifier string, epochNumber uint64)

AfterEpochEnd mints and allocates coins at the end of each epoch. If inflation is disabled as a module parameter, the state for "NumSkippedEpochs" increments.

func (Keeper) AllocatePolynomialInflation added in v1.1.0 

func (k Keeper) AllocatePolynomialInflation(
	ctx sdk.Context,
	mintedCoin sdk.Coin,
	params types.Params,
) (
	staking, strategic, community sdk.Coin,
	err error,
)

AllocatePolynomialInflation allocates coins from the inflation to external modules according to allocation proportions:

  • staking rewards -> sdk `auth` module fee collector
  • strategic reserves -> root account of x/sudo module
  • community pool -> `sdk `distr` module community pool

func (Keeper) BeforeEpochStart 

func (k Keeper) BeforeEpochStart(_ sdk.Context, _ string, _ uint64)

BeforeEpochStart: noop, We don't need to do anything here

func (Keeper) CirculatingSupply 

func (k Keeper) CirculatingSupply(
	c context.Context,
	_ *types.QueryCirculatingSupplyRequest,
) (*types.QueryCirculatingSupplyResponse, error)

CirculatingSupply returns the total supply in circulation excluding the team allocation in the first year

func (Keeper) EpochMintProvision 

func (k Keeper) EpochMintProvision(
	c context.Context,
	_ *types.QueryEpochMintProvisionRequest,
) (*types.QueryEpochMintProvisionResponse, error)

EpochMintProvision returns the EpochMintProvision of the inflation module.

func (Keeper) GetCirculatingSupply 

func (k Keeper) GetCirculatingSupply(ctx sdk.Context, mintDenom string) sdkmath.Int

GetCirculatingSupply returns the bank supply of the mintDenom excluding the team allocation in the first year

func (Keeper) GetEpochMintProvision 

func (k Keeper) GetEpochMintProvision(ctx sdk.Context) sdk.Dec

GetEpochMintProvision retrieves necessary params KV storage and calculate EpochMintProvision

func (Keeper) GetEpochsPerPeriod added in v1.2.0 

func (k Keeper) GetEpochsPerPeriod(ctx sdk.Context) (res uint64)

func (Keeper) GetInflationDistribution added in v1.2.0 

func (k Keeper) GetInflationDistribution(ctx sdk.Context) (res types.InflationDistribution)

func (Keeper) GetInflationEnabled added in v1.2.0 

func (k Keeper) GetInflationEnabled(ctx sdk.Context) (res bool)

func (Keeper) GetInflationRate 

func (k Keeper) GetInflationRate(ctx sdk.Context, mintDenom string) sdk.Dec

GetInflationRate returns the inflation rate for the current period.

func (Keeper) GetParams 

func (k Keeper) GetParams(ctx sdk.Context) types.Params

func (Keeper) GetPeriodsPerYear added in v1.2.0 

func (k Keeper) GetPeriodsPerYear(ctx sdk.Context) (res uint64)

func (Keeper) GetPolynomialFactors added in v1.2.0 

func (k Keeper) GetPolynomialFactors(ctx sdk.Context) (res []sdk.Dec)

func (Keeper) GetProportions 

func (k Keeper) GetProportions(
	_ sdk.Context,
	coin sdk.Coin,
	proportion sdk.Dec,
) sdk.Coin

GetAllocationProportion calculates the proportion of coins that is to be allocated during inflation for a given distribution.

func (Keeper) Hooks 

func (k Keeper) Hooks() Hooks

Return the wrapper struct

func (Keeper) InflationRate 

func (k Keeper) InflationRate(
	c context.Context,
	_ *types.QueryInflationRateRequest,
) (*types.QueryInflationRateResponse, error)

InflationRate returns the inflation rate for the current period.

func (Keeper) Logger 

func (k Keeper) Logger(ctx sdk.Context) log.Logger

Logger returns a module-specific logger.

func (Keeper) MintAndAllocateInflation 

func (k Keeper) MintAndAllocateInflation(
	ctx sdk.Context,
	coins sdk.Coin,
	params types.Params,
) (
	staking, strategic, community sdk.Coin,
	err error,
)

MintAndAllocateInflation performs inflation minting and allocation

func (Keeper) MintCoins 

func (k Keeper) MintCoins(ctx sdk.Context, coin sdk.Coin) error

MintCoins implements an alias call to the underlying supply keeper's MintCoins to be used in BeginBlocker.

func (Keeper) Period 

func (k Keeper) Period(

func (Keeper) Sudo added in v1.2.0 

func (k Keeper) Sudo() sudoExtension

Sudo extends the Keeper with sudo functions. See sudo.go.

These Sudo functions should: 1. Not be called in other methods in the module. 2. Only be callable by the x/sudo root or sudo contracts.

The intention behind "Keeper.Sudo()" is to make it more obvious to the developer that an unsafe function is being used when it's called.
