Types 

type Header struct {
	// contains filtered or unexported fields
}

Header is the V3 block header. V3 block header is exactly the same we copy the code instead of embedded v2 header into v3 when we do type checking in NewBodyForMatchingHeader the embedded structure will return v2 header type instead of v3 type
