func (Keeper) Slash 

func (k Keeper) Slash(ctx sdk.Context, pubkey crypto.PubKey, infractionHeight int64, power int64, slashFactor sdk.Rat)

Slash a validator for an infraction committed at a known height Find the contributing stake at that height and burn the specified slashFactor of it, updating unbonding delegation & redelegations appropriately

CONTRACT: 

slashFactor is non-negative

CONTRACT: 

Infraction committed equal to or less than an unbonding period in the past,
so all unbonding delegations and redelegations from that height are stored

CONTRACT: 

Infraction committed at the current height or at a past height,
not at a height in the future

func (Keeper) TotalPower

func (Keeper) Unrevoke 

func (k Keeper) Unrevoke(ctx sdk.Context, pubkey crypto.PubKey)

unrevoke a validator

func (Keeper) UpdateBondedValidators 

func (k Keeper) UpdateBondedValidators(ctx sdk.Context,
	affectedValidator types.Validator) (updatedVal types.Validator)

Update the validator group and kick out any old validators. In addition this function adds (or doesn't add) a validator which has updated its bonded tokens to the validator group. -> this validator is specified through the updatedValidatorAddr term.

The correct subset is retrieved by iterating through an index of the validators sorted by power, stored using the ValidatorsByPowerIndexKey. Simultaneously the current validator records are updated in store with the ValidatorsBondedIndexKey. This store is used to determine if a validator is a validator without needing to iterate over the subspace as we do in GetValidators.

Optionally also return the validator from a retrieve address if the validator has been bonded nolint: gocyclo TODO: Remove the above golint

func (Keeper) UpdateBondedValidatorsFull 

func (k Keeper) UpdateBondedValidatorsFull(ctx sdk.Context)

full update of the bonded validator set, many can be added/kicked

func (Keeper) UpdateValidator 

func (k Keeper) UpdateValidator(ctx sdk.Context, validator types.Validator) types.Validator

perfom all the nessisary steps for when a validator changes its power updates all validator stores as well as tendermint update store may kick out validators if new validator is entering the bonded validator group nolint: gocyclo TODO: Remove above nolint, function needs to be simplified

func (Keeper) Validator 

func (k Keeper) Validator(ctx sdk.Context, address sdk.AccAddress) sdk.Validator

get the sdk.validator for a particular address
