No, you can see that someone that CLAIMS to be me voted. This will enable hellish vote harvesting in every state.
In order for the blockchain to work, I would have to generate a unique address for myself. That address has to be confirmed by the blockchain. Every transaction have to be verified by the blockchain. If someone tries to insert a non verified record, it has to match or it gets rejected by the blockchain.
And the entire thing is open sourced and public.
It is obviously more complicated than that, but it is doable. You would have to register with the voting agency and create your address. It would be the same as verifying for an absentee ballot. Its just the system to vote would be secured under a new way.
Billions of dollars are transferred every day using the system. Inventories in the billions are managed this way. Medical records are managed this way. Every day. It is safe. It is secure. And it will save lots of time and money.
But, it is a change. Just like optical scanners and voting machines. My guess is you will live to see it. Not in 2020. But I bet that states are using some form of it in 2028.
