Functions

func FetchBLSValidators

func FetchBLSValidators(
	transition *state.Transition,
	from types.Address,
) (validators.Validators, error)

FetchBLSValidators queries a contract for validator addresses & BLS Public Keys and returns ECDSAValidators

func FetchECDSAValidators

func FetchECDSAValidators(
	transition *state.Transition,
	from types.Address,
) (validators.Validators, error)

FetchECDSAValidators queries a contract for validator addresses and returns ECDSAValidators

func FetchValidators

func FetchValidators(
	validatorType validators.ValidatorType,
	transition *state.Transition,
	from types.Address,
) (validators.Validators, error)

FetchValidators fetches validators from a contract switched by validator type
