Haechi: Simple Commitment-based Keyless In-person Verifiable Elections

Haechi introduces a novel, keyless, and commitment-based system for in-person verifiable elections, addressing the limitations of encryption-based approaches like ElectionGuard. By leveraging Peterson vector commitments and compact zero-knowledge proofs, Haechi ensures post-quantum ballot privacy, eliminates complex key management, and significantly reduces election record sizes, making E2E verifiable elections practical and scalable.
