As the Zcash ecosystem Security Lead, Zcash Community Grants (ZCG) requested we perform research, investigation, and review of the Coin Voting 2.0 which is designed as a voting system that aims to be privacy-preserving and secure. The voting system leverages Zcash Orchard’s shielded notes to utilize Zcash balances as verifiable voting power by converting ZEC into anonymous, coin-weighted votes. Coin Voting 2.0 runs the elections using a public ledger called the “Voting Blockchain,” which is a centralized ledger maintained by an Election Authority.
