func (*Backend) VerifyHeader 

func (sb *Backend) VerifyHeader(chain consensus.ChainReader, header *types.Header, seal bool) error

VerifyHeader checks whether a header conforms to the consensus rules of a given engine. Verifying the seal may be done optionally here, or explicitly via the VerifySeal method.

func (*Backend) VerifyHeaders 

func (sb *Backend) VerifyHeaders(chain consensus.ChainReader, headers []*types.Header, seals []bool) (chan<- struct{}, <-chan error)
