Coercion-Resistant Blockchain-Based E-Voting Protocol

Chiara Spadafora, Riccardo Longo, and Massimiliano Sala

Abstract

Coercion resistance is one of the most important features of a secure voting procedure. Because of the properties such as transparency, decentralization, and non-repudiation, blockchain is a fundamental technology of great interest in its own right, and it also has large potential when integrated into many other areas. Here we propose a decentralized e-voting protocol that is coercion-resistant and vote-selling resistant, while being also completely transparent and not receipt-free. We prove the security of the protocol under the standard DDH assumption.
