maybe,but i don't think so.because crypto currencies is already defined as universal currency. so what do you means by different crypto currencies for different country?
we use bitcoin and many other currencies for no getting exchange problem while Sending to others countries.
Exactly.
It is impossible, given current science, to develop a pow blockchain that can be contained in a country. You can do it with a special form of PoS but it will have a dishonest origin of money problem like all POS chains. Eg: PayTM type currency can be done.
Given our current knowledge it is impossible to tie a cryptocurrency to a dynamic geography.
Proof-of-location is a theoretical concept and measuring distance from the 14 nearest pulsars is not feasible at the moment.
Every other point-of-reference in the universe we know of is dynamic.
Theoretically, you cant even define a country's boundary because geography is changing all the time.
There is a reason why land is measured by patwaris w.r.t nearby geographical landmaps and not GPS coordinates!
Think about it - if we simply define everyone's land precisely as per coordinates, a technology that every smartphone has, there will be no land disputes right?
Awesome. Why don't we do it then?
Because land changes and thus we measure it relatively and not absolutely.
Also, any logic that justifies national cryptocurrencies would also justify state cryptocurrencies or even a village/town specific cryptocurrency. (dillicoin, rampurcoin, etc.)The only counter argument that would not, is that the jurisdiction and people would want a common national cryptocurrency to allow for trading valuations.
But this stands against the very principal of design of cryptocurrencies wherein an individual could posses multiple national cryptocurrencies and be trading in them in this globalized world, being restricted only by exchange of physical goods (whereas
digital goods incur no such restriction and thus renders the digital trader
indistinguishable from the native of land).
