Although of course it seems unlikely, all good things must come to an end and someday, in the distant future, the blockchain technology will fail. When it happens, what could replace it? Is there anything out there that functions similarly and just as good and reliable as blockchain? More importantly, if nothing replaces it, what will happen to cryptocurrencies then? Any ideas?
Why does it happen, we should first solve what is the problems with it right now, and leave other things for people to come. Blockchain is the crux of the technology in this era and now we have to get this accepted first.
