ALERT: This function mutates validatorPerformances slice based on the votes made by the validators.

Keeper of the oracle store

func NewKeeper 

func NewKeeper(cdc codec.BinaryCodec, storeKey sdk.StoreKey,
	paramspace paramstypes.Subspace, accountKeeper types.AccountKeeper,
	bankKeeper types.BankKeeper, distrKeeper types.DistributionKeeper,
	stakingKeeper types.StakingKeeper, distrName string) Keeper

NewKeeper constructs a new keeper for oracle

GatherRewardsForVotePeriod retrieves the pair rewards for the provided pair and current vote period.

func (Keeper) GetExchangeRate 

func (k Keeper) GetExchangeRate(ctx sdk.Context, pair asset.Pair) (price sdk.Dec, err error)

func (Keeper) GetExchangeRateTwap added in v0.17.0 

func (k Keeper) GetExchangeRateTwap(ctx sdk.Context, pair asset.Pair) (price sdk.Dec, err error)

func (Keeper) GetParams 

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

GetParams returns the total set of oracle parameters.

func (Keeper) GetWhitelistedPairs added in v0.16.1 

func (k Keeper) GetWhitelistedPairs(ctx sdk.Context) []asset.Pair

GetWhitelistedPairs returns the whitelisted pairs list on current vote period

func (Keeper) IsWhitelistedPair added in v0.16.1 

func (k Keeper) IsWhitelistedPair(ctx sdk.Context, pair asset.Pair) bool

IsWhitelistedPair returns existence of a pair in the voting target list

func (Keeper) Logger 

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

Logger returns a module-specific logger.

func (Keeper) MinValidPerWindow 

func (k Keeper) MinValidPerWindow(ctx sdk.Context) (res sdk.Dec)

MinValidPerWindow returns oracle slashing threshold

func (Keeper) MinVoters added in v0.19.0 

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

VoteThreshold returns the minimum percentage of votes that must be received for a ballot to pass.

func (Keeper) RewardBand 

func (k Keeper) RewardBand(ctx sdk.Context) (res sdk.Dec)

RewardBand returns a maxium divergence that a price vote can have from the weighted median in the ballot. If a vote lies within the valid range defined by: 

μ := weightedMedian,
validRange := μ ± (μ * rewardBand / 2),

then rewards are added to the validator performance. Note that if the reward band is smaller than 1 standard deviation, the band is taken to be 1 standard deviation.
