The traditional FOO e-voting protocols adopt centralized and non-transparent count center, which leads to distrust to the center and doubts the fairness and correctness of the vote. However, blockchain is the most innovative technology in the current era and promises to solve the trust problem in the system with one center. In this paper, an improved FOO e-voting protocol is proposed using blockchain, which tries to address the limitation or weakness in existing systems. The traditional trusted third party is replaced by smart contract; specifically, our scheme is deployed using hyperledger fabric. The implementation is enforced by the consensus mechanism, which ensures the security of the blockchain. Through the analysis, the proposed scheme is proved to satisfy the necessary requirements for an e-voting protocol; meantime the trust assumption is reduced significantly. Therefore, the proposed protocol is more versatile and practical.

使用区块链的改进的FOO投票方案

传统的FOO电子投票协议采用集中式和不透明的计数中心，这导致对该中心的不信任，并怀疑投票的公平性和正确性。但是，区块链是当前时代最具创新性的技术，有望以一个中心解决系统中的信任问题。本文提出了一种使用区块链的改进的FOO电子投票协议，旨在解决现有系统的局限性或弱点。传统的受信任的第三方已被智能合约取代；具体来说，我们的方案是使用Hyperledger Fabric部署的。该实现由共识机制执行，可确保区块链的安全性。通过分析，证明该方案满足了电子投票协议的必要要求。同时，信任假设大大降低。因此，提出的协议更加通用和实用。
