ZKVote: The Invisible Ballot That Could Unite the World.

This is a submission for the Midnight Network "Privacy First" Challenge - Protect That Data prompt

What I Built

ZKVote is a decentralized voting DApp that empowers global citizens to anonymously vote on humanity’s next big innovation priority — from climate tech to ethical AI. Built on the Midnight Network, it uses zero-knowledge proofs to verify voter eligibility without revealing identity, ensuring privacy and trust in every vote.

The app solves a critical problem: how can we enable global participation in decision-making without compromising personal data or exposing individuals to surveillance, bias, or retaliation?

Demo

ZKVote Repo 👉

• Voting dashboard with animated innovation cards
• ZK proof submission interface
• Real-time global results heatmap “Your vote has been encrypted” confirmation modal

How I Used Midnight's Technology

ZKVote is built using:

• MidnightJS for smart contract logic and blockchain interactions
• Compact language to define zero-knowledge circuits for voter eligibility
• Mocked tokens to simulate unique voter credentials
• Privacy-preserving smart contracts that store encrypted votes and prevent double voting using nullifiers

Data Protection as a Core Feature

Privacy isn’t a layer — it’s the foundation. ZKVote ensures:

• No personal data is ever stored or exposed
• Voter identity is never linked to vote content
• One vote per user is enforced using ZK nullifiers
• All votes are encrypted and stored on-chain in a format that’s publicly auditable but completely anonymous This design allows people to vote freely, especially on sensitive global topics, without fear of surveillance or profiling.
