Leo Vote

Summary

vote.leo is a general vote program.

Anyone can propose new proposals, proposer can issue tickets to the voters, and the voter can vote without exposing privacy (with the help of Aleo's flexible privacy mechanism).

Proposal information and statistical voting results is public, while the correlation between the voter and the vote is private(protected by zk).

This example is inspired by the aleo-vote example written by the Aleo community.
