Update private chain from homestead to byzantium

Question

I need to update my the version of my chain from homestead to Byzantium. Who can tell me how to do it? thanks.

Answer 1

I think you need to modify params\config.go function :

// IsByzantium returns whether num is either equal to the Byzantium fork block or greater.
func (c *ChainConfig) IsByzantium(num *big.Int) bool {
    return isForked(c.ByzantiumBlock, num)
}

Can return true to allow Byzantium rules.
