And no country is actually using blockchain for voting, which would be extremely stupid if they even tried it.
Why its stupid? It addreses vote tampering which is known in any election (fraud/cheating) although there's no country uses it for national election yet. But there already some "stupid" of them uses already in small scale voting for pivot testing
[1] in city, organization, etc. in different countries already.

it wouldn't do anything except make the system slow, expensive, and error prone because it would be brand new untested systems.
Like lots of blockchain "projects" that had happened a few years ago, people blindly put the words, "blockchain" on anything because the price of Bitcoin went to a half trillion dollars and that convinced them at anything made with "this blockchain thingy" must be awesome. But blockchain doesn't solve any problems that voting systems actually
have since it makes the system inherently
less secure, slower, and more expensive to create (can you imagine every vote taking 15 minutes to cast?).
And voting is quite necessarily
not anonymous, which is the very opposite of what a blockchain system does. If all votes were anonymous and not connected to an actual person but rather just a private key, then tampering and vote rigging would actually be easier than ever before.
