A blockchain model for ensuring privacy, trust, and dependability of electronic voting systems

Abstract

Electronic voting systems face critical challenges in privacy, trust, and scalability. This paper proposes PQSHAC, a post-quantum secured hybrid consensus mechanism that combines hierarchical authoritative consensus with optimized sharding for scalable e-voting applications. The proposed system achieves approximately 106 blocks per second throughput while reducing storage requirements by 60% through its modular ledger architecture.
