Candidate for Prime Minister of Georgia:

All taxes, except VAT, will be supported by and based on Blockchain technology

According to him:

The country has progress in the implementation of technologies in tax administration, but is trailing those countries whose economy is effectively managed by digital technologies.

Although Georgia is a small European nation with only 4 million population but it is worth to mention that blockchain technologies are vastly developing in Georgia and the country is very friendly to cryptocurrencies as well.

Note that one of the largest data processing centers is located in the capital of Georgia. The center was owned and managed by "Bitfury" and recently was sold to Chinese investors.
