Suppose I create a country where all currency is a cryptocurrency with tracked transactions. All income and outcome for a given country is registered in a block chain. All the public workers (specially all those working for the government) will get paid with the cryptocurrency associated to that blockchain and their accounts will be public. Taxes will be paid in that cryptocurrency.
Is financial corruption possible in such a country? If corruption is still possible, then is it possible if every country in the world used the same trackable blockchain?
