I guess not that many government will switch to blockchain technology especially those who are not that advanced in technology yet since it will be a hassle especially to those countries that got slow internet speed. Maybe some will follow to Georgia's footsteps but only a counted few country will change to blockchain technology. Some will just do the same as they usually do.
I believe governments will switch to blockchain!At least all the big economical strong nations.
BUT it probably won't be an open permissionless one.
The govs will use closed, permissioned blockchains, only certain individuals wil have access to,just to speed up certain processes.
That the citizens will be able see in full transparency how governments are using their tax money for instance is never going to happen!
Politicians are the biggest criminals.In politics is no place for transparency and fairness.
