Hybrid Voting Systems: Leveraging Blockchain and Zero-Knowledge Proofs for Provable Manipulation Resistance

Papers like Barakka et al. (2025) and Kumar et al. (2025) show the promise of combining blockchain and zero-knowledge proofs (ZKPs) for privacy and integrity. However, the focus is almost always on vote secrecy and correctness, not direct manipulation resistance. This idea proposes to design hybrid voting protocols where voters must prove (in zero knowledge) not only that they voted legitimately, but that their vote cannot be part of a known manipulation pattern (e.g., vote buying, coordinated misreporting). Develop formal definitions of “ZKP-enforced manipulation resistance,” and prototype such systems on testnets. This moves the manipulation conversation from abstract impossibility theorems to concrete, cryptographically-enforced guarantees—potentially raising the bar for what “strategy-proof” can mean in the real world.
