What does op_return do? Looked it up in mastering bitcoin: 0x6a halt and invalidate transaction. Must be more to it if it is what allows Memo etc.
love that someone can post "what does op_return do" on memo, using op_return. good sign for the future! on boarding people who don't have to know how BCH works to use it!
I'm sure lightning will be like that one day😝. Gives me a good idea for a slogan. "Don't get burnt by lightning, use Bitcoin Cash!" Could also say struck, hit, shocked.
