IF i had the chance to managed a certain government i would really apply blockchain technology and give their budget in a form of cryptocurrency or digital currency that could be used as a form of payment and could even trade to fiat money. In this way we could eradicate the corruption because the public could be aware on where the budget of the people coming from taxes will going through. Yet, until now the government is not interested on cryptocurrency or if they are they are not willing also to investigate and checked how cryptocurrency works and how could it will be applied on their system. They just want their business to continue as usual doing ghost project? I do not know maybe!
I think eventually blockchain technology will be use if blockchain can approve that they are worth and useful as it said by many people. Its will takes time to change system and to imppement a new system and it were not that easy. Every thing should change step by step and rush just make something bad out of it.
