}

prove of authority. using round robin algorithm to generate blocks with orders in the list of authority peers. this consensus is used by sub chain using asimov. please refer to the white paper of asimov.

func NewService

func NewService(config *params.Config) (*Service, error)

* create POA Service

func (*Service) GetRoundInterval

func (s *Service) GetRoundInterval() int64

func (*Service) Halt

func (s *Service) Halt() error

func (*Service) Start

func (s *Service) Start() error

* start the Service
