Why end-to-end verifiability matters

Many online election systems used today have technical or procedural gaps that open doors to speculation or risk. End-to-end verifiability closes these by delivering proof that election results are true and accurate.

Distributed trust

Independent officials approve the configuration and share parts of the keys required to decrypt votes.

Voter eligibility

Distributed voter credentials from at least two independent providers ensure eligibility.

Vote secrecy

Client side encryption and the secure ballot opener app verifies the vote cryptogram.

Public ballot box

A bulletin board is used to register and verify encrypted votes and other system activity.

Voting result

Irreversible separation of votes and voter IDs ensures anonymity and decryption of votes.
