not that easy to answer
DMD is one of the oldest POS coins
but it did take in lot code from its successors
and it did improve custom code parts too
fact is we are not technology bound in any way
DMD Diamond define itself trough coin rollout plan
the longterm active hard working core team
and the special trust relationship between core team and community
so if u look at it from that point DMD Diamond could surprise easy with a technology jump or shift of platform base
and still stay the same DMD Diamond
just with more abilities.....
