Agreed completely. Usage of AI is a political issue. The tech can be used both for the good and bad. However, just because it can be used for the bad doesn't make the tech bad.
Development in nuclear science made a bomb that could end civilisation. It also gave us a pathway to solve climate change. How we use the tech should be an issue. The tech itself shouldn't be.
Which means elections. Which means a dude/committee in charge of a server. See the problem?
This is a very very interesting topic that I've spent a rlly long time thinking about. I wish I had more energy to go in depth for this. The gist is this:
There will be a tradeoff between anonymity and "vote buying".
You can have absolute anonymity by implementing a monero like blockchain. Each registered voter address gets one token. The thing that you can cast a vote for is also an address. The voter sends this token to an unknown address (that theoretically belongs to the voter themselves). Then, the voter votes from this address. This way, absolute anonymity is maintained as noone knows who sent the token to the address in the middle. BUT. I could buy votes like this too. I could bribe a voter to send their token to the middle address, which I control.
To prevent voter buying, you can have an open blockchain where all transactions are visible to everyone. However, you get pseudo anonymity here. Every registered voter address gets one token like above. No one except for the election commission knows which address belongs to whom. So while the election commission cannot manipulate votes, it can leak who voted for whom.
Now that being said, normal elections aren't as theoretically anonymous as well. For ballots, your name is on the envelope. A compromised election commission could leak this info as well. For EVMs, one line of code could leak who you are. The person granting you entry can note down your information. The EVM can ping this person as to which vote was cast while you were in there.
Hence, in my opinion, the second option of the open blockchain is the best one provided that the election commission is under strict regulation (which it generally is in any case).
