Juvenal: The universal election verifier

• Demo: https://nvotes.github.io/juvenal
• Source code documentation: https://nvotes.github.io/juvenal/doc

juvenal is an universal election verifier for the web browser. It is voting system agnostic, and allows anyone to verify an election record of multiple voting systems. The proofs verification is implemented in juvenal-lib.

It enables the verification of election ballots, tallies, and proofs generated by multiple voting solutions. It has been developed independently by the nVotes Online Voting team and is written in TypeScript. It also includes a command line verifier. It currently only supports verifying ElectionGuard. Work for supporting Helios Voting is in the works.
