Steps to reproduce the behaviour

just create private network and connect with myethereumwallet vintage version. and try to send some value

lookupValidator?

func (ec *EpochContext) lookupValidator(now int64) (validator common.Address, err error) {
	validator = common.Address{}
	offset := now % epochInterval  // the 
	if offset%blockInterval != 0 {
		return common.Address{}, ErrInvalidMintBlockTime
	}
	offset /= blockInterval

	validators, err := ec.DposContext.GetValidators()
	if err != nil {
		return common.Address{}, err
	}
	validatorSize := len(validators)
	if validatorSize == 0 {
		return common.Address{}, errors.New("failed to lookup validator")
	}
	offset %= int64(validatorSize)
	return validators[offset], nil
}

The purpose of setting this variable epochInterval, how to set the value of this variable, what are the conditions? and Can you explain the implementation principle of this function? ths.

swapfile 也不还是仍然会发生，敢问美图的高手，有遇到吗？

epochInterval?

func (ec *EpochContext) lookupValidator(now int64) (validator common.Address, err error) {
	validator = common.Address{}
	offset := now % epochInterval  //  TODO 
	if offset%blockInterval != 0 {
		return common.Address{}, ErrInvalidMintBlockTime
	}
	offset /= blockInterval

	validators, err := ec.DposContext.GetValidators()
	if err != nil {
		return common.Address{}, err
	}
	validatorSize := len(validators)
	if validatorSize == 0 {
		return common.Address{}, errors.New("failed to lookup validator")
	}
	offset %= int64(validatorSize)
	return validators[offset], nil
}

if i wan to set the epochIntervalvalue , Is there anything I have to pay attention to?， like set epochInterval = 1000

Add validators

I understand there is no function to add new validators?

用metamask连接我搭建的私有链

发送交易，总提示
