It’s not the people who vote that count, it’s the people who count the votes.
There can be no democracy without a democratic process. Luckily, we have exactly all the right tools for secure voting today.
For deeper dive into technical details I recommend reading Vitalik Buterin’s blog post:
The same cryptographic tools have proven successful as they already secure hundreds of billions of dollars in live protocols, and several trillion dollars secured by blockchain overall.
It’s time to move from “those who count the votes decide everything” to those who vote decide everything.
references to related (but different) blockchain policies:
Yes blockchain isn’t strictly necessary, membership proofs could be enough - but if two votes are sent by the same signer then you have byzantine fault.
