I don’t get it, seems totally unnecessary to me? Sats has been working just fine.
Furthermore the abstract says the goal is to ‘reduce confusion’ and yet it’s suggesting to achieve that we go to a world where I’m explaining to the uninitiated ‘oh yeh that is a bit confusing, but once you understand that 1 bitcoin is comprised of 100,000,000 bitcoins it will all become much clearer’.
As I said I don’t get it, seems like a really stupid thing to want to change, but maybe I am missing something.
