It ' s not specs but space lol . As in writing space , because her name is too long already . <| sep |> The most limiting hardware would probably be storage . I mean , of course 4 or even 20 MB seems OK nowadays , but the VISA tps would probably need 600 MB blocks . If it get filled your HDD would get full very quickly and only data centers would be able to run full nodes . SegWit seems to be smart and scaling smartly is good . If we encounter a wall , increasing the blocksize the hard way will probably be considered . <| sep |> Haha i used to have this issue when i was a kid . Now i just bite the skin on the tips of my fingers if im nervous . My mom used to put me through hell trying to break me out of my habit . had me in public with tape around my fingers and even dip them in crazy hot pepper sauce that would be effective all day
