Maintaining Voting Integrity using Blockchain

The potentials of using blockchains and distributed ledgers to support voting processes have attracted significant attention in the electronic voting community. Most of these recent ideas are centered on blockchain-based e-voting protocols. Others focus on how blockchain can be exploited to simultaneously deliver auditability and anonymity of voters in the voting process. A common feature of these research efforts is the use of blockchain within e-voting contexts. We elaborate in this work the integrity requirements that must be supported by blockchain in online voting as well as offline voting prevalent in developing countries. The framework conditions for blockchain-based voting are also discussed.
