This is too technical for an ordinary cryptocurrency enthusiast, however I will try to contribute my opinion on this topic. 10 years ago the bitcoin blockchain was born and many said that it is worthless and it is just another geeks minds idea that will not last the moment of its birth. Anyway 10 years and it is still being rejected that it will soon die. To restart the blockchain is possible but it will cause another fear, uncertainty and doubt to the cryptocurrency enthusiast. Having this idea is a selfish initiative that only takes the advantage of every person who believes in the blockchain technology that is now a phenomenon and might give fair opportunity to everyone.
