That is actually a good idea but we all know that allied countries will not favor that. The United States of America will be the number one to go against that. They will not allow that the US dollars will not be on top and they will do anything just to stay at the top of the financial and economic system.
I am not very sure how does the system you mentioned works since the link that you gave cannot be opened, hope I can read it to give sufficient and knowledge based opinion on this matter.
part of loosening the grip of the dollar is by china being part of BRIC's* where several countries join together to have their own pricing arrangement away from the dollar
*
Brazil
Russia
India
China
ofcourse the IMF are still top of the financial pyramid but it has become widely known that the IMF is moving away from the dollar as the dollar is losing power.
as for blockchain based info.. this will be part of hyperledger. and not related to using bitcoin
as for america's reaction..
well forget syria, forget russia.. trump is obviously got his sights set on china.. just look at his pre election speaches and obsession about the word china.
look at the american 'patriots' on this forum who are obvious trump supports shouting and crying about china's dominance of bitcoin.
its obvious the propaganda machine of fox news will start pushing for support to go to war with china for any little reason they can find
in the early 2000's america got saudi arabia onboard. they are now getting russia onboard (yea forget the fox news spit for spat against russia), america loves russia and gives them billions to help nasa..
whats gonna happen next is after the saudi landgrab of UAE, syria, lybia is over.. america along with their new allies and this will include australia. uk france saudi, etc will start in the mongolia region of china and then move east while also attacking from the oceans on the east heading west to flank on both fronts.
