Ballot Blockchain System Design and Development on Ethereum Platform

摘要

Ballots are often held for fair decisions such as party theme selecting; however, the existing traditional ballots have some problems involving amount of human resources, cost of places, equipment, time and traffic, and repeated procedures. In order to solve the aforementioned issues, a ballot blockchain system is designed and implemented based on the smart contract of Ethereum. It is designed on the core blockchain technologies of the decentralized ledger technology, using a secure hash algorithm, anonymous user, incorruptible data, and adopting a public blockchain. The ballot blockchain system is implemented based on the MetaMask verification and the Remix interface development environment. The smart contract plays the role of the decision maker for controlling ballot activities instead of numerous human tasks. All ballot transactions are recorded in the ballot blockchain permanently when the ballot is completed. The aim of the ballot blockchain system is to achieve a fair, less time-consuming, secured, and transparent environment.
