Leo Vote

Summary

vote.leo is a general vote program.

Anyone can issue new proposals, proposers can issue tickets to the voters, and voters can vote without exposing their identity.

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

Noteworthy Features

Voter identity is concealed by privately passing a voter's ballot into a function. Proposal information and voting results are revealed using the public mapping datatype in Leo.
