I am intrigued by your comment that older systems should not be a part of blockchain platforms (if I understood you correctly).
I am spending time on putting together an idea I have which actually marries blockchain to older financial instruments and coding systems, so may, at some time, I should ask you to read my thoughts and comment. (My intentions are not for creating personal wealth for me, what I want is to help those fighting to survive - both the public and small traders). Maybe it is only a dream and not practical...or maybe, the dream can be converted into something more concrete. Time will show.
