A Survey of Blockchain Based on E-voting Systems

Blockchain technology as a decentralized and distributed public ledger in a P2P network has recently gained much attention. In this technology, a linked block structure is applied, and a trusted consensus mechanism is established to synchronize data modifications, making it possible to develop a tamper-proof digital platform for data storage and sharing. We think that blockchain could be used in various interactive online systems, such as the Internet of Things, supply chain systems, voting systems, etc. The scope of this survey is to shed light on some recent contributions of the security and privacy issues associated with e-voting based on blockchain. At the end of this paper, we provided a comparison for the security and privacy requirements of the existing e-voting systems based on blockchain.
