Voting using current bitcoin may become quite hard to trace or hard to authenticate as well as distributing voting coin is not possible in controlled way. So i think to enable voting later on under blockchain tech, government will develop their own centralized voting coin and only high class authority have control over distribution of all coins that were developed, for example number of coins equal total elligible person's count for voting.
No, I don't think it is hard. Assuming that everybody is anonymously assigned a personal BTC address for voting purposes I think it is really easy and could work as described by OP. Of course the public is not yet ready to execute such a voting system based on Bitcoin software alone. A system would have to implemented to make use for all end users extremely easy and intuitive (there are a lot of elderly voters). The clear advantage is that manipulation during the vote counting would become impossible, because everything will be recorded and secured via crypto.
Of course, governments in their current state of mind will have objections on using the Bitcoin blockchain for such purposes. They haven't even warmed up to Bitcoins core functionality (decentralized cash)... Another question is of course: To what degree do governments really want to prevent vote manipulation?
ya.ya.yo!
Regarding intuition, I was thinking of making simple web clients where you input your key/QR code and the site would translate the candidate you are voting for into the address you send your coin. I thought difficulty may lie within transaction fees mounting for many low priority single satoshi transactions. Or if this was done on a regtest network, how many nodes or computers you would need participating.
In regards to the regtest method, the network could be vulnerable to 51% attack if only a few computers participate. It seems like it would be easier if the network could be modified to only allow specific computers to participate, or if mining did not create coins and there were finite coins for voting, if this makes sense? Unless I am mistaken and the regtest network is already permissioned (ie. random computers can't join and overwhelm the network?)
