Corrupt officials in some countries will not go for the use of blockchain technology, but European countries with low levels of corruption are likely to integrate this technology into their structure and further reduce the level of corruption. But this is just one example of the use of blockchain technology in the economic structure of a country.
Anyways if you look other side your opinion is good since it will reveal the truth what government is doing with our money. If the government is corruption they never use it and i know almost all governments are doing corruption.
I am sure a lot of corrupt settings in the world where corruption has dug so deep, will find it hard to implement blockchain technology into the system to prevent corruption. In these places, the level of oppression due to the fact that some are just extremely rich looting funds that belong to the whole country's development has been going into their own pockets.
However, as time goes on, we will get them being pushed and forced one way or the other, but unless there is some enforcement and there is a leadership serious enough to bring development into the country, nothing will change much if it is never utilized effectively.
